Quality control of cast steel bricks

When the steel brick passes through the molten steel, it must withstand high temperature erosion, and the inner wall will have residues hanging on the inner wall of the brick, and some manufacturers will require the use of two or more times.

However, if the production of poured steel bricks is improved, the flat bottom is changed to the bottom of the pot, so that the circulation is fast, the inner wall will not hang slag, even if the use of the inner wall hang slag, slight knock off the slag, can be reused. However, in the production process, the level of production personnel is a big technical test.

First of all, start from the mold, if the bottom is made live, the casting steel brick is easy to handle, but it is easy to cause the lower part of the brick is not dense, if the bottom of the pot is made dead, so that you can press the bottom porcelain in the process of pressing the brick, but the semi-finished product is not convenient, but in order to be more convenient to use, then use the solid bottom to press the brick, the technical requirements of the brick skilled workers, The brick produced in this way is easy to knock off the inner wall slag when in use and make repeated use.

After the casting steel brick is solved from the forming part, it is the sintering problem, because the casting steel brick has a special shape, it can only be installed in the upper part of the kiln car, so as to ensure that the burned brick does not deform, but this is bound to cause a long burning cycle problem, and only when the upper part also has the appropriate temperature of the underlying brick, it is burned together with the lower brick, so the cost will increase.

Pressed brick, fired brick these two big decisions can be fired out of the appropriate cast steel brick, but one of them is to use two fillers when pressing the brick, if the powder of a filler aggregate is formed at one time, it is bound to cause the brick surface rough, if the first mix a certain proportion of the material pressed into, and then the powder scattered on the pressed surface, In this way, the appearance and inner wall of the cast steel brick are smooth, which helps the flow more smoothly.

In short, the production process of casting steel bricks is more complex than that of ordinary bricks, and the process of pressing bricks is not the same, and then the master of sintering temperature during the firing process can ensure that the product can be used well.
