Refractory and wear-resistant bricks, as core foundational materials in high-temperature wear-resistant industries such as metallurgy, cement, power, and chemical engineering, are widely used in the inner linings of key equipment such as blast furnaces, rotary kilns, boilers, and wear-resistant pipelines. They are subject to multiple tests including extreme high temperatures, material erosion, chemical corrosion, and mechanical wear over long periods. Their service performance directly determines the operational stability, service life, and production efficiency of terminal equipment. The uniformity of the body density, compactness, and wear resistance are the core indicators for evaluating the quality of refractory and wear-resistant bricks. Currently, the technical limitations of traditional forming equipment have led to problems such as rapid wear, cracking and peeling, and short service life of refractory and wear-resistant bricks, making it difficult to meet the demands of high-end, green, and intelligent development in the industry. Zhengzhou Haloong Machinery Co., Ltd. has been deeply engaged in the field of refractory forming equipment for 45 years. Through technological innovation in servo screw presses, it has solved the forming problems of refractory and wear-resistant bricks, and with the core advantages of its equipment, it has produced high-quality refractory and wear-resistant bricks, providing global refractory enterprises with full-process precise forming solutions.

The forming quality of refractory and wear-resistant bricks directly determines their wear resistance, high-temperature stability, and service life. Their raw materials are mostly high-hardness aggregates (such as corundum, silicon carbide, high-alumina bauxite) mixed with fine powder and binders. The mixed materials have poor fluidity, complex particle size distribution, and extremely high requirements for the accuracy of applied pressure, pressure application speed, and holding time.

Zhengzhou Haloong has deeply studied the raw material characteristics, forming process logic, and industry upgrading demands of refractory and wear-resistant bricks. With the core technology of direct drive by permanent magnet synchronous servo motor + static pressure flexible pressure transmission + intelligent numerical control system, it has specially optimized the HLDS series of servo screw presses, comprehensively upgrading the equipment's precision, stability, and adaptability, precisely solving the forming problems of refractory and wear-resistant bricks, and becoming the preferred equipment for mass production of high-quality refractory and wear-resistant bricks, assisting refractory enterprises in creating high-end products suitable for extreme working conditions.

Equipped with a direct drive system of permanent magnet synchronous servo motors, it completely eliminates the inefficient transmission structures such as traditional friction discs and clutches, with an extremely short transmission chain and zero energy loss in energy transmission. The pressure output is fully stable and controllable throughout the process. The equipment is equipped with Haloong's independently developed numerical control pressure control module for refractory and wear-resistant bricks, which can digitally and precisely set the impact energy, pressure application speed, stepwise pressure application times, and holding time. The energy repetition control accuracy is ≤±1%, ensuring that the pressure for each forming process is highly consistent, completely eliminating quality deviations caused by manual operation and mechanical fluctuations. In response to the poor fluidity and easy agglomeration of refractory and wear-resistant brick mixed materials, a customized stepwise flexible pressure application process is adopted. First, light pressure is applied to quickly expel the residual air inside the body, then stepwise stable pressure is applied layer by layer to compact it, and finally, long-term pressure holding is used for shaping. This ensures that all parts of the body, including the center, edges, and corners, are uniformly stressed, with density fluctuations controlled within a very small range. The density variation coefficient is far superior to industry standards, perfectly ensuring the uniform and dense quality of the entire body, significantly enhancing the wear resistance, impact resistance, and high-temperature stability of the finished product, and extending its service life.

It adopts a fully enclosed static pressure screw, nut, and dedicated heavy-duty bearing transmission structure. During operation, a stable high-pressure oil film is formed for protection, achieving flexible and uniform pressure application and completely avoiding the severe impact force and stress concentration problems caused by traditional rigid pressure application. The pressure application process is smooth and gentle, which can not only fully expel the internal pores of the body, completely eliminating porosity and delamination defects, but also gently protect the brittle body structure, avoiding edge and corner damage and internal micro-cracks. This increases the product qualification rate to over 99%, significantly reduces the waste of high-cost raw materials, and effectively extends the service life of molds, reducing material costs and improving production efficiency for enterprises. Breaking through the structural limitations of the fixed bottom dead center of traditional equipment, it adopts a successive forging forming mode. According to the material (high alumina, corundum, silicon carbide), size, and structural complexity (standard brick, special-shaped brick, composite wear-resistant brick) of the refractory wear-resistant brick, it can flexibly adjust the stroke of the slider, the depth of pressure application, and the pressure intensity, precisely meeting the forming requirements of various refractory wear-resistant bricks. It covers the full range of refractory material production scenarios in industries such as metallurgy, cement, and power. There is no need to worry about the deviation of raw material filling volume or uneven pressure application due to complex structures. Combined with a rapid mold changing system, it enables convenient and efficient mold changing, perfectly adapting to the flexible mode of multi-variety and batch production, and meeting the batch supply requirements of large-scale industrial projects.

The equipment is equipped with a dedicated forming parameter database for refractory wear-resistant bricks, integrating the optimal forming process parameters for various specifications and different materials of refractory wear-resistant bricks, including common products such as high alumina wear-resistant bricks, corundum composite wear-resistant bricks, and silicon carbide wear-resistant bricks. Operators can retrieve them with one click, eliminating the need for repeated debugging and exploration, and significantly reducing the interference of human factors on product quality. All forming parameters can be permanently saved and reused in batches, ensuring that the density, compactness, and dimensional accuracy of each batch and each product are highly consistent, easily meeting the strict quality requirements of large-scale industrial projects at home and abroad, and helping enterprises smoothly open up the overseas high-end refractory material market.

Compared with traditional friction presses, the Haloong servo screw press adopts an on-demand start-stop and sleep energy-saving intelligent mode. The servo motor only operates during the pressing process, and the standby state has zero energy consumption. The comprehensive energy-saving rate is over 55%, significantly reducing the electricity cost of refractory wear-resistant brick production, and meeting the green and low-carbon development needs of the refractory material industry. At the same time, the static pressure transmission structure has minimal wear, and is combined with a fully automatic forced lubrication system and an oil shortage alarm device, achieving maintenance-free operation, with a low failure rate and a service life far exceeding that of traditional equipment. The later maintenance cost is reduced by more than 40%, comprehensively compressing production, maintenance, and consumable costs, and helping enterprises achieve a green, low-carbon, and efficient production model.

The equipment is equipped with standardized industrial communication interfaces, which can be seamlessly linked with automatic and precise feeding machines, closed-loop distribution machines, intelligent demolding machines, non-destructive testing equipment for green bodies, and constant-temperature conveyor lines, building an automatic and intelligent forming production line for refractory wear-resistant bricks. It realizes unmanned control throughout the entire process from distribution, pressing, pressure holding, demolding to green body transfer and inspection, minimizing human intervention and ensuring forming accuracy and production efficiency. At the same time, it supports remote monitoring, parameter adjustment, fault warning, and production data traceability functions, facilitating domestic and foreign customers to remotely and real-time control production progress and product quality, fully conforming to the global trend of intelligent, digital, and green transformation in the refractory material industry, and helping enterprises build intelligent production bases for high-end refractory wear-resistant bricks.
