Refractory production is a high-energy-consuming, high-material-consuming, and labor-intensive industry. The current predicament of efficiency improvement and consumption reduction in refractory production lines at home and abroad lies in the performance shortcomings of forming equipment, coupled with the limitations of traditional production methods, resulting in low overall production line efficiency. Research data shows that refractory production lines using traditional friction presses and ordinary hydraulic presses not only have a qualified product rate of less than 85%, with a raw material waste rate of 15% to 30%, but also have a unit product energy consumption 40% higher than the industry's advanced level. Moreover, each production line requires 6 to 8 operators, with high labor costs.

Specifically, the core pain points of efficiency improvement and consumption reduction in refractory production lines are concentrated in four aspects: First, low forming efficiency. Traditional equipment has slow pressurization speed and complex stroke control, with an average daily output of less than 800 pieces per unit. Moreover, mold replacement and parameter adjustment take a long time, seriously affecting the continuity of the production line and making it difficult to meet the demands of large-scale production. Second, high energy consumption. Traditional friction presses and hydraulic presses operate continuously, consuming a large amount of electricity even during non-pressing periods, with energy losses during transmission reaching 30% to 50%. This makes it difficult to meet the global trend of green and low-carbon energy conservation. Third, severe raw material waste. Due to insufficient pressure control accuracy, the green bodies are prone to cracks, chipped corners, and porosity, with a large number of unqualified green bodies unable to proceed to the next process. Additionally, uneven material distribution during the forming process further exacerbates raw material waste, contrary to the development direction of efficient utilization of waste in the refractory industry. Fourth, high reliance on manual labor. Traditional forming equipment requires manual parameter adjustment, auxiliary loading and unloading, and quality inspection of green bodies. Human operation errors not only affect production line efficiency but also lead to quality differences in the same batch of green bodies, making it difficult to meet the demands of intelligent manufacturing upgrades.

With the global high-temperature industry's transition towards green and low-carbon, high-precision, and high-end, the refractory industry is gradually upgrading towards high-density, high-strength, low-carbon, and intelligent production. "High efficiency, energy conservation, low carbon, and intelligence" have become the core competitiveness for the survival and development of refractory enterprises. The domestic and international markets have put forward more stringent requirements for the efficiency and energy consumption of refractory production lines, not only requiring large-scale and efficient production but also demanding a significant reduction in unit product energy consumption and a significant increase in raw material utilization to cope with international carbon rules and reduce overall production costs. Against this backdrop, Zhengzhou HALOONG, relying on 45 years of equipment research and manufacturing experience, has combined the raw material characteristics and forming process features of various refractories (high alumina, magnesia, carbon, silica, etc.) to optimize and upgrade the servo screw press, launching dedicated equipment for various refractory production lines, covering the full tonnage range from 200T to 1600T. With core technology, it has solved the pain points of efficiency improvement and consumption reduction in production lines, becoming a core support for global refractory enterprises to achieve green and efficient production and break through development bottlenecks. It showcases the technical strength of "HALOONG" as the leading brand of electric screw presses, helping enterprises break free from the constraints of traditional production models and achieve high-quality development.

Zhengzhou HALOONG's HLDS series servo screw press, as a national patent product, adopts the third-generation permanent magnet synchronous servo motor direct drive technology, aligning with the global high-end refractory forming equipment standards. It targets the core pain points of refractory production line efficiency improvement and consumption reduction, creating a full-process precise forming and intelligent control system. It can perfectly adapt to the batch forming and customized production of common refractories, high-density refractories, special-shaped refractories, and complex-structured refractories. Its six core advantages comprehensively enhance production line efficiency and reduce energy consumption, helping refractory enterprises achieve the core goal of "30% efficiency improvement, 60% energy conservation, and raw material utilization rate increased to over 99%". It meets the upgrade demands of intelligent manufacturing production lines for domestic and international refractory enterprises, empowering the green and efficient upgrade of the refractory industry through equipment innovation. Adopting a direct drive design with permanent magnet synchronous servo motors, it discards the traditional clutch and gear transmission structure, achieving precise digital control of the press speed, pressure, and stroke. The energy repetition control accuracy is ≤±2.5%, approaching the level of the world's top servo forming equipment. It can precisely meet the special forming requirements of various refractory materials, such as "light pressure exhaust, heavy pressure forming, and gradient compaction". The precise pressure control can effectively prevent defects such as cracks, chipped corners, and porosity in the green bodies, stably increasing the green body qualification rate to over 99%, significantly reducing the waste of raw materials caused by unqualified green bodies, and raising the raw material utilization rate to over 99%. This aligns with the technical trend of efficient utilization of waste and by-products in the refractory industry. Additionally, the servo motor only outputs energy during the pressing operation, without any unnecessary energy loss. Compared to traditional friction presses, the energy consumption per unit product is directly reduced by over 60%, with a motor efficiency of ≥95%. This significantly reduces energy consumption in the forming process, helping enterprises cope with challenges posed by international carbon border adjustment mechanisms and other green regulations.

Overcoming the shortcomings of traditional equipment, such as slow press speed and cumbersome stroke control, the HALOONG servo screw press adopts a design without a fixed bottom dead center, allowing flexible adjustment of forming parameters. It can quickly adapt to the forming requirements of different materials and specifications of refractory materials without complex debugging. The mold change time is reduced by more than 50%. Moreover, when the equipment approaches the bottom dead center, the slider speed is extremely fast, enabling the completion of the forming process before the refractory raw materials and binders cool down. The daily output of a single machine can be increased to over 1,200 pieces, with an efficiency improvement of over 30% compared to traditional equipment. The production capacity of a single production line can easily meet the needs of refractory material intelligent manufacturing projects with an annual output of 50,000 tons or more. The efficient forming performance can reduce the waiting time of the production line, enabling continuous and large-scale production of green bodies, significantly enhancing the overall efficiency of the production line, and helping enterprises quickly respond to domestic and international market orders.

It features a fully enclosed static pressure screw, nut, and bearing transmission structure, forming a stable oil film for protection during operation. Combined with an automatic forced lubrication system, it effectively reduces equipment wear. Compared to ordinary screw presses, the service life is increased by more than double. The transmission chain is short and the structure is simple, without friction discs, gearboxes, and other easily damaged and consumable parts. Later maintenance is convenient, with maintenance costs reduced by over 60% and equipment failure rates reduced by over 60%, ensuring continuous and stable operation of the production line and reducing downtime losses caused by equipment failures. At the same time, the equipment operates smoothly, with no vibration at low speeds, avoiding uneven material distribution and green body quality deviations caused by vibration, further reducing raw material waste and rework losses, indirectly enhancing the overall efficiency of the production line, and providing stable support for large-scale and efficient production of refractory material production lines.

Equipped with the intelligent production management system independently developed by Zhengzhou HALOONG, it is equipped with standardized industrial communication interfaces, enabling seamless integration with upstream and downstream equipment such as automatic feeding systems, raw material proportioning systems, spray release agent equipment, automatic green body picking robots, and green body inspection equipment, achieving full automation and digital control of the refractory green body forming process.

Full automation operation can significantly reduce the reliance on manual labor, with only 2-3 operators required per production line, reducing the workforce by over 60% compared to traditional production lines, significantly lowering labor costs. At the same time, the equipment can receive real-time data from upstream raw material proportioning and feeding speed, automatically adjusting the forming parameters to avoid parameter deviations caused by manual intervention, ensuring consistent quality of green bodies in the same batch and reducing rework losses, further enhancing production line efficiency. Additionally, the system supports remote monitoring and parameter adjustment, facilitating remote control of production by domestic and foreign customers. The operation is simple and easy to learn, with one-button operation that does not require skilled operators, helping enterprises achieve the dual goals of "reducing staff and increasing efficiency". Relying on the core advantages of servo direct drive technology, the equipment achieves the "start on demand, sleep for energy saving" mode, with no unnecessary power consumption. It not only complies with the domestic "Emission Standard of Air Pollutants for Refractory Materials Industry" (GB 41618-2022), but also meets overseas environmental protection standards and carbon reduction requirements, helping refractory material enterprises obtain the "green pass" for the international market. Meanwhile, the equipment operates without transmission noise, significantly improving the workshop working environment and achieving green production. The precise forming process can reduce raw material waste and pollutant emissions, promoting the refractory industry's transformation towards low-carbon and green development, in line with the global industrial green development trend. Additionally, the equipment's performance is on par with international top levels, but its price is only one-tenth of that of similar foreign equipment, enabling enterprises to reduce input costs while enhancing product quality and market competitiveness, and easily meeting the demands of the overseas high-end refractory market.

As a fundamental supporting industry for high-temperature industries, the green and efficient development of the refractory industry directly affects the energy conservation, safety, and sustainable development of global high-temperature industries. Enhancing production efficiency and reducing consumption is the key to achieving structural optimization, value-added improvement, and low-carbon transformation in the refractory industry. Currently, the global refractory industry is transforming towards "high efficiency, long life, low carbon, and intelligence".
