The issue of the speed at which coke ovens are built
Thread Content
I remember when I went to Canada for heat treatment of coke ovens, an expert said that no more than a few layers of silica bricks could be laid on the oven each day. . I don’t understand why. Does any expert know why? Where does this theory come from? Thank you :)
The number of floors varies in different locations; it is usually three floors. What’s important is that the clay’s property is that its strength increases as the temperature rises; at room temperature it has little strength and is soft, like dough, making it difficult to create proper seams when building structures with it. Let the fireclay dry layer by layer
Remember, the regenerator is very important; the lattice bricks must be placed correctly, and the correct model must be used. We’ve suffered the consequences of placing them improperly back then – now they’re severely deformed, which causes great damage to the furnace
Three layers in general areas, one layer in the ramp area. The consistency of the mud is important, and the weight of the bricks also needs to be taken into account.
Generally, no more than 4 layers are built in one day, and the height difference between adjacent walls should also not exceed 4 layers; the main reasons for this are the slow curing speed of the mortar and the high load-bearing capacity of the wall surfaces, which can lead to deformation
Different leaders have different requirements; some demand 3 layers, while others require 5 layers, but generally it is 3 to 6 layers (1 layer per day in the ramp area). With an increasing number of construction layers, and given that silicon bricks are relatively heavy while the newly laid mortar is soft, it is difficult to control the elevation levels as well as the size of the brick joints.
