In the forming process of refractory materials, traditional open and semi-closed presses often suffer from severe wear of core components due to dust intrusion and insufficient lubrication. This not only causes frequent shutdowns that disrupt production continuity, but also leads to a rising defect rate of products due to the degradation of equipment precision. Targeting these issues, Zhengzhou Haloong has optimised the equipment structure in a targeted manner, adopting a fully enclosed transmission design with hydrostatic screws, hydrostatic nuts and hydrostatic bearings. This design ensures that the core transmission components are protected by a clean oil film throughout operation. Combined with a dedicated fully automatic forced lubrication station that enables circulating filtration and high-pressure oil supply, it fundamentally isolates refractory dust erosion and eliminates component damage caused by omissions in manual refueling. Verified by practical applications, the service life of key equipment components has been more than doubled compared with traditional equipment, which greatly reduces the operation and maintenance costs and unplanned shutdown losses of refractory manufacturers, and ensures the continuous and stable operation of production lines.

    High-end refractory materials (such as magnesia-carbon bricks, corundum bricks and special-shaped refractory products) have stringent requirements for forming precision and density uniformity, and minor errors may lead to potential hazards such as spalling and cracking under high-temperature working conditions. Zhengzhou Haloong's fully enclosed hydrostatic servo screw press is equipped with direct drive technology of permanent magnet synchronous servo motor, abandoning the traditional clutch transmission mode. It features no idle stroke response time and a much faster operation response speed. Cooperated with high-precision displacement sensors and a closed-loop control system, it can accurately preset and real-time adjust the pressing energy, slide stroke and operation speed. The slide stroke control precision reaches ±0.05mm and the energy fluctuation is ≤±0.5%, ensuring that refractory materials are pressed and formed in the optimal plastic range. This precise control capability effectively improves the dimensional accuracy and density uniformity of products, avoids internal defects such as looseness and cracks, and makes the product qualification rate far exceed the industry average, fully meeting the stringent forming process requirements of high-end refractories.

    The current refractory material industry is accelerating its transformation towards green and intelligent development, with high efficiency, energy saving, low noise and environmental protection becoming the core demands of enterprise upgrading. In equipment R&D, Zhengzhou Haloong has thoroughly implemented the concept of green manufacturing. The fully enclosed hydrostatic structure greatly reduces transmission losses, and the servo motor is only activated during the working cycle. Compared with traditional friction presses, the comprehensive energy saving rate exceeds 55%, which significantly reduces the unit energy consumption of refractory production. At the same time, the equipment adopts a fully enclosed frame design, with pressure acting on the internal structure. The noise and vibration during operation are much lower than those of traditional impact equipment, and no complex ground foundation engineering is required. This not only improves the workshop operating environment, but also saves infrastructure investment for enterprises, perfectly complying with the national green factory construction standards and helping refractory enterprises achieve low-carbon transformation.

    Facing the development trend of high-end, intelligent and green development in the refractory material industry, Zhengzhou Haloong will continue to increase R&D investment, deepen the integrated innovation of fully enclosed hydrostatic technology with digital and automated technologies, optimise equipment performance for segmented fields such as special-shaped refractory products and high-performance refractories, and expand intelligent application scenarios. Backed by 40 years of technical accumulation in forging and pressing equipment, Zhengzhou Haloong is willing to tailor exclusive forming solutions for refractory enterprises, and work together to solve production pain points and enhance core competitiveness. We welcome refractory enterprises from all over the country to visit and negotiate, jointly build a new ecology for high-end refractory material manufacturing, and achieve a win-win future for industrial upgrading!
