Abstract:

In the production of siliceous bricks for hot blast stove, the method of mixing loading of checker bricks with other shaped bricks that is used in the past is changed and the centralized loading of checker bricks on the selected kiln cars in “two-step pit” location in tunnel kiln is done and the brick setting method is improved. Therefore the finished product qualified rate of checker bricks is raised and no influence on finished product rate of other shaped bricks is ensured.
