How to avoid spalling of refractory brick blank with electric numerical control Screw press

The formation of Fire brick is to use external force and model to compress the material of the brick, so that the material in the mold becomes a billet with a certain size, shape, density and strength. This is an important process for preparing Fire brick. The quality of the formed product directly affects the quality of the final product. The electric numerical control Screw press relies on digital control to control the speed of pressurization and decompression at will, and even control the pressure curve of each brick in the porous mold to ensure the reasonable distribution of pressure in time and space. It is beneficial for eliminating gas, achieving automatic control, and obtaining bricks with uniform density, accurate size, and less peeling, thus obtaining high-quality bricks.

The quality of the blank is represented by unit weight, size, and qualification rate. Common defects (such as missing edges, corners, honeycomb like, pitted surfaces, and peeling) can affect the pass rate of forming. However, the most serious defect is hidden peeling. In order to reduce peeling, when using a friction brick press, the rule of "light first, then heavy, and slow lifting" should be followed for operation. The "headlights" mainly consist of exhaust gas. The compressed gas remaining in the brick will significantly increase the elastic post effect of the brick. The 'rear weight' is to increase the density of bricks. Slow head up "is to slow down the decompression speed and reduce the elastic aftereffect. Even so, the friction brick press is still formed through stamping, and the internal quality and external dimensions of the bricks produced are difficult to accurately control. The electric numerical control Screw press solves this big problem.

The peeling phenomenon of Fire brick usually requires one, two or three times of treatment to remove, but it is usually difficult to remove. Therefore, improving the quality of Fire brick and reducing the possibility of spalling is a pressing process of Fire brick. The important part of product quality control is to reduce the brick peeling phenomenon, which can be well controlled after using the electric numerical control Screw press. It is also increasingly widely used in this industry.
