Abstract:

In view of the bricking furnace door of coke oven’s defects such as short life，difficult to repair，easy to dissipating heat and often product glutinous，the article analyzed the cause of destroying，advance a new theory about improving the structure of lining，developing the new materials and using a new method by whole pouring.Combine the method with smearing materials on the lining,the new method guarded against damage of the lining，let the life of the furnace door have more than tripled,reduced the loss of heat and cut down the worker’s work load.Achieve the aim of safe production，energy conservation and long life.
