Because the problem of the billet crack of fire clay bricks is complicated and all kinds of reasons are intertwined, so it is not easy to distinguish which type of billet is. At the time of the emergence of the billet, we must pay special attention to understand, analyze and find the root cause. As to the same type of crack, we need to judge that timely whether the crack is a high temperature crack or low temperature crack, so as to make the temperature control during the drying process, humidity control, pressure control and gas flow control.
The status of the temperature and the heat flow, the size and direction of the gas flow play an important role on cracks. Improve the front temperature which is generally controlled at 100 degrees, and the horizontal temperature of the surface of the dry kiln should be controlled within 15. Upper and lower temperature difference should be the smallest and drying temperature should be stable. In the middle section of dry kiln, the top and side of the kiln inlet should be equipped which can adjust the temperature difference between the upper and the lower temperature.
