In the production process of refractory brick, the crack problem is always a troublesome problem. Whether it is due to brick shape, molding mold, uneven cloth or operation and molding pressure, the generation of cracks may lead to a decline in product quality, and even cause waste.

Take high aluminum brick as an example, its forming process may cause cracks for various reasons. Among them, the unreasonable brick design, the lack of exhaust groove and vent hole in the molding mold, the uneven fabric and the problems of the molding operation and the molding press may lead to the crack.

In order to solve this problem, Zhengzhou Hualong developed a synchronous servo electric screw brick press. This brick press adopts a special molding process, first light pressure exhaust, and then re-molding, which effectively reduces the crack problem of refractory bricks and improves product quality.

Specifically, the servo electric screw press, through precise control and pressure regulation, can achieve a combination of light pressure exhaust and heavy molding during the molding process. In the light pressure exhaust stage, the press gradually compacts the material at a lower pressure while discharging the gas within it, thereby reducing the compression and residue of the gas inside. In the remolding stage, the press strikes and shapes the material at a higher pressure to achieve the required compactness and shape.

This special molding process can not only effectively reduce the cracks on the surface of refractory brick, improve the quality and aesthetics of the product, but also improve the production efficiency and reduce the production cost. Compared with the traditional press, the servo electric screw press has higher forming accuracy and more stable performance, and can meet the forming needs of various complex brick shapes.

In short, Zhengzhou Hualong synchronous servo electric screw brick press through its special molding process and precise control technology, successfully solved the problem of surface cracks of refractory bricks, providing strong support and guarantee for the production of refractory bricks.
