When traditional friction presses and ordinary hydraulic presses are used for the formation of refractory slab bricks, the core pain points are particularly prominent: Firstly, the pressure control accuracy is low, and it is difficult to flexibly adjust the pressing force according to the proportion and particle size distribution of aluminum-carbon raw materials. This often leads to defects such as loose centers, over-pressed corners, and surface cracks in the bricks. It is especially difficult to control the uniform distribution of graphite particles, resulting in a low product qualification rate and inability to meet the requirements of high-end continuous casting processes. Secondly, the force transmission is uneven, and the complex transmission structure leads to high energy loss, making it impossible to achieve uniform pressure throughout the entire blank. The density variation coefficient of the brick exceeds the standard, and it is prone to peeling and damage due to stress concentration during high-temperature service, shortening the service life of the slab brick and increasing the downtime and replacement costs during continuous casting production. Thirdly, parameter adjustment is cumbersome. For different specifications and raw material proportions of refractory slab bricks, manual adjustment of stroke and pressure parameters is required, resulting in low mold change efficiency and poor adaptability, making it difficult to balance the demands of large-scale mass production and customized production. Fourthly, the energy consumption is high and maintenance is difficult. Traditional equipment has a lot of ineffective energy consumption, with energy consumption 50% higher than servo equipment. Moreover, the core components wear out quickly, and remote control is difficult, making it unsuitable for global production layouts. At the same time, the implementation of international rules such as the EU's carbon border adjustment mechanism, along with rising labor costs and stricter environmental protection requirements, further urges refractory slab brick manufacturers to upgrade their forming equipment and seek efficient, precise, energy-saving, and intelligent forming solutions.

Compared with traditional forming equipment, the servo screw press, with its core advantages of digital precision pressure control, flexible adaptability, and energy efficiency, is the best choice for the formation of refractory slab bricks. It can not only solve the problems of uneven pressure and high defect rate of traditional equipment but also make up for the shortcomings of ordinary hydraulic presses, such as lagging response and high energy consumption. It perfectly meets the core production requirements of refractory slab bricks, such as high density, precise dimensions, stable performance, and energy conservation, and is more suitable for the green and intelligent transformation trend of the refractory materials industry, helping enterprises enhance their core competitiveness.

Relying on 45 years of experience in the research and development and manufacturing of refractory forming equipment, Zhengzhou Haloong has deeply integrated the third-generation permanent magnet synchronous servo direct drive technology with the semi-dry forming process of refractory slab bricks, creating a dedicated servo screw press for refractory slab bricks. It meets the global high-end equipment standards and, based on the characteristics and particle size requirements of aluminum-carbon raw materials, achieves the core goals of "precise pressure control, flexible adaptability, high efficiency and energy conservation, and stable reliability". It has become a "core weapon" for domestic and foreign refractory slab brick manufacturers, comprehensively solving the industry's forming pain points and promoting the transformation of refractory slab brick production towards high quality, high efficiency, and low energy consumption.

It adopts a permanent magnet synchronous servo motor direct drive design, eliminating the traditional clutch and gear transmission structure. The transmission chain is short and energy loss is low. It is equipped with an intelligent pressure control system that can precisely preset the pressing energy, speed, and frequency through digital programs, with a repeatable control accuracy of pressure ≤ ±1%, far exceeding the industry average. It intelligently matches the three-stage forming process of "light pressure exhaust - medium pressure shaping - heavy pressure densification" to meet the core requirements of refractory slab bricks for "exhaust - densification - formation". It thoroughly eliminates the internal pores of aluminum-carbon raw materials, effectively solving the layer cracking and delamination problems caused by traditional equipment pressing. At the same time, it precisely allocates the pressing force according to the proportion and particle size distribution of aluminum-carbon raw materials, ensuring uniform density from the center to the edge of the blank, with a density variation coefficient controlled below 1.5% and a porosity reduced to below 15%. This significantly improves the compressive strength, resistance to steel water erosion, and thermal shock resistance of refractory slab bricks, effectively eliminating forming defects such as cracking, corner chipping, and porosity. The product qualification rate is stable at over 99%, fully meeting the international and domestic refractory material industry standards and the quality requirements of high-end continuous casting processes for slab bricks. Breaking through the structural bottom dead center limitations of traditional equipment, the servo screw press adopts a sequential forging mode. It can flexibly adjust the slider stroke and press angle according to the requirements of different specifications and thicknesses of refractory sliding board bricks, without worrying about overload jamming caused by material size deviations or changes in raw material properties. Whether it is standard sliding board bricks, special-shaped sliding board bricks, large sliding board lining bricks, or customized sliding board brick products, precise forming can be achieved, ensuring that the dimensional accuracy error of the brick body is controlled within ±0.5mm, perfectly replicating the mold shape, eliminating problems such as edge material deficiency and dimensional deviation, and ensuring the precise fit of the sliding board brick with the sliding water mouth, avoiding the risk of steel leakage. At the same time, the equipment can flexibly adapt to aluminum-carbon billets with different compression ratios without frequent adjustments to the equipment structure, significantly enhancing the forming adaptability and helping enterprises expand their refractory sliding board brick product matrix to meet diverse market demands.

Relying on 45 years of refractory forming process experience, the servo screw press can intelligently customize forming programs and press parameters based on the characteristics of aluminum-carbon raw materials from different origins and with different ratios. For different specifications of refractory sliding board bricks, it is equipped with a rapid mold changing system, making mold replacement convenient and efficient. Combined with the built-in refractory sliding board brick forming parameter database, it can automatically adjust the press energy, speed, and stroke according to product requirements without frequent manual adjustments, significantly reducing production preparation time. The equipment has a high single-stroke processing efficiency and can achieve continuous and stable mass production, with a production efficiency improvement of over 30% compared to traditional friction presses. It can meet both small-batch customized production and large-scale mass production needs, helping enterprises quickly respond to domestic and international market orders and enhance market competitiveness.

Equipped with the intelligent production management system independently developed by Zhengzhou Haloong, it is equipped with standardized industrial communication interfaces and can be seamlessly linked with upstream and downstream equipment such as automatic feeding systems, raw material ratio systems, billet detection equipment, and intelligent storage systems, building an intelligent production line for the entire process of refractory sliding board brick forming, achieving unmanned control from "raw material entry - ratio - pressing - inspection - storage". The system supports remote monitoring and parameter adjustment, facilitating remote control of production by domestic and foreign customers, real-time collection of forming data, providing data support for process optimization, reducing errors caused by manual intervention, and is simple and easy to operate, even for non-professionals, significantly reducing labor costs and improving production stability, in line with the global trend of intelligent manufacturing.

Adopting the "on-demand start, sleep energy saving" intelligent mode, the servo motor only operates during the forming process, and stops and sleeps during feeding, demolding, mold changing, and other processes, without unnecessary power consumption. Compared to traditional friction presses, it saves more than 55% of energy, with motor efficiency ≥ 95%, saving a large amount of energy costs for enterprises each year. At the same time, the equipment intelligently optimizes the forming process, shortens the forming cycle, intelligently matches mold fitting parameters, reduces billet rework losses, and increases the utilization rate of aluminum-carbon raw materials to over 99%, reducing raw material waste and carbon emissions, meeting global carbon reduction requirements and the green transformation needs of the refractory industry, helping enterprises achieve multiple goals of "energy conservation, cost reduction, and efficiency improvement", and enhancing their competitiveness in the international market.
