Description

Technical Field

[0001] The invention belongs to the technical field of refractory materials, and in particular relates to a refractory material production device. Background Art

[0002] There are many refractory materials used in existing buildings. Refractory bricks are an extremely important type of refractory material in the field of refractory materials. The brick blanks of refractory bricks are mixed with a variety of refractory raw materials, including refractory clay, high-alumina bauxite, silica, etc. Refractory bricks are generally formed by pressing the refractory materials with a forming press and then firing them. For example, a two-way pressurized refractory brick forming press is disclosed in the invention patent with the authorized patent announcement number CN115319892B, in which the upper plate of the mold is fixedly arranged at the lower position of the upper hammer head; the sliding rails are fixedly arranged at the left and right sides of the upper inner side of the press frame; the forming mold is fixedly arranged on the upper part of the forming mold bracket, and the forming mold bracket is fixedly arranged on the bottom of the press frame; the lower hydraulic cylinder is fixedly arranged at the bottom middle position of the forming mold bracket, and the upper and lower surfaces of the brick blank are pressurized by the upper and lower hydraulic cylinders to improve the density of the upper and lower surfaces of the brick blank, so that the density of the upper and lower surfaces of the brick blank can also be better controlled.

[0003] In the existing refractory brick blank forming equipment, when a press is used to extrude the refractory material in the mold box, the pressure mainly acts vertically on the upper and lower surfaces of the brick blank. In this case, the material is subjected to greater pressure in the vertical direction, and the particles will be more tightly compacted. For the side of the brick blank, it is mainly formed by the lateral flow and filling of the material under the constraint of the box under the action of vertical pressure. The pressure on the side is generated by the lateral extrusion force after the material is compressed in the vertical direction. This extrusion force is smaller than the pressure in the vertical direction, so the degree of bonding between the particles is relatively weak, resulting in the upper and lower surface strength of the brick blank being higher than the side strength. In order to improve the tightness of the side of the refractory brick blank in the prior art, a refractory material production equipment that can improve the side strength of the refractory brick blank is needed. Summary of the invention
