In the refractory industry, it has long been a universal consensus that "raw materials lay the foundation, and forming processes determine quality". As downstream sectors such as steel, cement and ceramics raise demands for the long-cycle stable operation of high-temperature equipment, the homogenization level of refractory products has become a core indicator determining their service life, thermal shock resistance and high-temperature creep properties. With 45 years of dedicated expertise in the refractory forming equipment field, Zhengzhou Haloong Machinery Manufacturing Co., Ltd. takes the servo electric screw press as the core carrier, and provides full-process solutions for the homogeneous production of refractory products through precise control and cutting-edge technology, empowering the industry to shift from "passive adaptation" to "proactive creation of stability".

The homogenization of refractory products essentially means offsetting the compositional fluctuations and uneven phases of natural minerals through industrialized methods, and realizing the performance consistency control from raw materials to finished products. In traditional production, even after fine batching and mixing, uneven pressure and energy control deviations in the forming stage will still lead to inconsistent billet density and disordered internal pore distribution. These minor defects will be amplified drastically after high-temperature calcination, ultimately affecting the overall performance of products. Especially with the popularization of composite homogenization technology, the introduction of functional raw materials such as andalusite and kyanite has placed higher demands on the pressure precision and stability of forming equipment – and Zhengzhou Haloong’s servo electric screw press is the key equipment to solve this problem.

Precise Energy Control: Laying the Core Foundation for Homogenization

Haloong’s servo electric screw press adopts servo motor direct drive technology, abandoning the traditional clutch transmission mode to achieve precise presetting and repeated execution of pressing energy. The pressure output error of each stroke is close to zero, fundamentally ensuring that every product bears the same forming energy. Tailored to the characteristics of refractory production, the equipment can simulate manual striking processes and realize programmed control of "light pressing for air exhaust first, heavy striking for forming later", effectively avoiding defects such as air holes and delamination inside billets and ensuring uniform brick density. Compared with traditional friction presses, the energy control precision of Haloong’s equipment is improved by more than 30%, providing core technical support for product homogenization.

Structural Optimization: Strengthening the Stability Guarantee for Homogenization

Haloong’s refractory-specialized press features a fully enclosed hydrostatic structure. The screw, nut and bearing form a stable oil film through a forced lubrication system, which not only extends the equipment service life to twice that of ordinary models, but also ensures the smoothness and consistency of slide movement, avoiding pressure fluctuations caused by mechanical wear. With a structural bottom-dead-center-free design, the equipment can flexibly adjust the pressing force and frequency according to raw material characteristics, achieving adaptive forming for different batches of raw materials. It also effectively avoids the risk of overload jamming, guarantees the continuity and stability of the production process, and eliminates the impact of human operation and equipment failures on homogenization from the process level.

Intelligent Collaboration: Building a Full-Process Homogenization System

Zhengzhou Haloong deeply understands that homogeneous production is not the independent effect of a single device, but the result of full-process collaboration. Its presses can seamlessly connect with automatic weighing and feeding systems, online inspection and palletizing equipment, and the Haloong Cloud Network Platform, forming a fully automated production line from batching, feeding and forming to inspection. The automatic weighing and feeding system ensures precise and consistent raw material dosage for each mold; the press achieves standardized forming; online inspection equipment screens out unqualified products in terms of size and density in real time; and the Cloud Network Platform enables full traceability of production data, realizing a high degree of consistency in product performance between batches through digital management and control. After a silicon carbide brick manufacturer introduced Haloong’s complete set of equipment, the product dimensional accuracy deviation was controlled within ±0.5mm, the rejection rate was reduced by 40%, and the homogenization level was significantly improved.

Green and High Efficiency: Balancing Homogenization and Economic Efficiency

While ensuring homogeneous quality, Haloong’s presses demonstrate remarkable energy-saving and environmental protection advantages. The servo motor operates only during working cycles, saving more than 55% energy compared with traditional friction presses. Combined with low-noise and low-vibration design, it drastically reduces production energy consumption and environmental impact. The slide moves at an extremely high speed when approaching the bottom dead center and has a short contact time with the mold, which not only improves forming efficiency, but also reduces mold wear and lowers comprehensive production costs. This "high quality + high cost performance" feature enables small and medium-sized refractory enterprises to easily achieve the upgrading of homogeneous production.

As the refractory industry transforms toward high-end and green development, homogenization will become a key indicator of enterprises’ core competitiveness. Zhengzhou Haloong will continue to focus on technological innovation, optimize the precise control and intelligent collaboration capabilities of its presses, and provide more targeted solutions to help refractory enterprises break through quality bottlenecks and lay a solid foundation for the high-quality development of the industry. Zhengzhou Haloong always advances side by side with refractory enterprises, forging homogeneous quality with ingenuous equipment and empowering industrial upgrading with technological innovation.
