Refractory materials, as the core foundational materials for high-temperature industries such as steel, cement, glass, and non-ferrous metals, directly affect the safe production and equipment service life ofdownstream industries. With the expansion of global refractory material market demand, large-scale and efficient production has become the core competitiveness for refractory material enterprises to capture the market. High-speed pressing forming technology has become an inevitable trend in the industry's development. However, the technical shortcomings of traditional forming equipment have severely restricted the development of the refractory material high-speed forming industry.

 Specifically, the core pain points of refractory material high-speed pressing forming are concentrated in three aspects: First, the imbalance between high speed and precision. Traditional friction presses and ordinary hydraulic presses have lagging responses, poor pressure control accuracy during high-speed pressing, unstable energy release, which can lead to uneven internal stress distribution in the green body, resulting in cracks, chipped corners, and uneven density, making it difficult to increase the green body qualification rate, with a raw material waste rate as high as 20% to 35%. Second, insufficient stability during high-speed operation. Traditional equipment has complex transmission structures, with high friction losses and severe vibrations during high-speed operation, not only increasing the equipment failure rate but also further affecting the forming accuracy, making it impossible to achieve long-term continuous high-speed production. Third, limited adaptability. Traditional equipment has a fixed structure, making it difficult to flexibly adapt to the forming requirements of different materials (high alumina, magnesia, carbon, etc.) and different specifications of refractory materials, especially for the high-speed forming of large and irregular refractory materials, which can lead to deformation, dimensional deviations, and other problems, resulting in low equipment utilization.

 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, benchmarking against the global high-end refractory material forming equipment level. It targets the core demands of "high-speed response, precise pressure control, stable reliability, and energy efficiency" in refractory material high-speed pressing forming, creating a full-process intelligent high-speed forming system. It can perfectly adapt to the high-speed batch forming of various refractory materials such as standard refractory bricks, irregular bricks, honeycomb lattice bricks, and large prefabricated blocks, helping refractory material enterprises reduce costs, increase efficiency, improve quality, and expand production. It meets the upgrade needs of domestic and foreign refractory material enterprises' intelligent manufacturing production lines, reshaping the new paradigm of refractory material high-speed forming with equipment innovation.

 Adopting a direct drive design with permanent magnet synchronous servo motors, it discards the traditional clutch and gear transmission structures, featuring a short transmission chain and rapid response. The motor start response time is ≤0.03 seconds, and the empty stroke speed of the slider is increased to over 300mm/s. Near the bottom dead center, the slider speed can be instantly increased, achieving rapid compaction and forming of refractory materials. Compared to traditional equipment, the HALOONG servo screw press increases the forming speed by more than 50%, with an average daily brick pressing capacity of over 1,500 pieces per unit. It can achieve continuous and large-scale high-speed mass production, significantly shortening the delivery cycle, helping refractory material enterprises quickly respond to market demands and enhance market competitiveness. At the same time, the equipment adopts a "demand-driven start, sleep energy-saving" mode, with no unnecessary power consumption, and motor efficiency ≥95%, achieving a dual breakthrough in high-speed forming and energy conservation and emission reduction, in line with global carbon reduction requirements.

 It overcomes the shortcoming of pressure loss of control during high-speed pressing of traditional equipment, equipped with HALOONG's independently developed precise pressure control system, with energy repeat control accuracy ≤±1%. Pressure and stroke can be precisely preset through digital programs, achieving a stepwise forming process of "high-speed exhaust and precise compaction", effectively eliminating internal pores in the green body, ensuring uniform density and precise dimensions during high-speed pressing. Additionally, the equipment has no fixed bottom dead center design, allowing flexible adjustment of pressing parameters based on raw material characteristics and forming requirements, avoiding local over-pressing or under-pressing during high-speed pressing, stabilizing the green body qualification rate at over 99%, significantly reducing the rework losses of unqualified green bodies, and increasing raw material utilization to over 99%, reducing production costs from the source. By referring to the advanced technical standards of the industry, HALOONG has optimized the pressure control algorithm to keep the density variation coefficient during high-speed forming below 1.5%, far exceeding the industry average. This ensures the high-temperature stability and erosion resistance of refractory products.

 The equipment adopts a fully enclosed static pressure screw, nut and bearing transmission structure. During operation, a stable oil film is formed for protection, and it is combined with a fully automatic forced lubrication system. This effectively reduces the friction loss during high-speed operation, and the equipment wear is reduced by more than 70% compared to ordinary screw presses, with the service life increased by more than one fold. The transmission structure is simple and the operation is stable. During high-speed operation, the vibration is small and the noise is low. The equipment failure rate is reduced by more than 60%, allowing for 24-hour continuous high-speed production. This reduces the downtime losses caused by equipment failures and ensures the continuity of production. At the same time, the equipment is equipped with a dual braking protection device. In case of power failure or emergency stop, the slider automatically rises to the upper limit point, eliminating the risk of jamming and safety accidents, providing double protection for high-speed forming production and meeting the needs of large-scale continuous production.

Equipped with the intelligent production management system independently developed by Zhengzhou HALOONG, it is equipped with standardized industrial communication interfaces, which can be seamlessly connected with upstream and downstream equipment such as automatic feeding systems, raw material proportioning systems, demolding agent spraying equipment, automatic part removal robots, and green body inspection equipment, achieving full automation and digital control of the entire refractory high-speed pressing process. Full automation operation can significantly reduce the reliance on manual labor. Each production line only requires 2-3 operators, reducing the workforce by more than 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, and automatically adjust the forming parameters to avoid parameter deviations caused by manual intervention, ensuring consistent quality of refractory products in the same batch and further improving the efficiency of high-speed forming. In addition, the system supports remote monitoring and parameter adjustment, facilitating the remote control of production by domestic and foreign customers. The operation is simple and easy to learn, and stable production can be achieved without skilled operators, reducing the training costs of enterprise personnel.

Refractory materials industry, as a core supporting industry for high-temperature industries, its forming technology upgrade and iteration directly relate to the energy conservation, safety production and sustainable development of global high-temperature industries. It is also an important breakthrough for the refractory materials industry to transform towards high-end and high value-added. Currently, the global refractory materials industry is accelerating the transition from the traditional low-efficiency and low-quality forming mode to a high-speed, precise, intelligent and green direction.
