LUBRICANT FOR OVEN FLOOR OF COKE OVEN CARBONIZATION CHAMBER

摘要

Disclosed is a lubricant for the oven floor of a coke oven carbonization chamber, which can be easily spread on the oven floor of a coke oven carbonization chamber and can largely reduce the load on an extruder when coke is extruded from the carbonization chamber after the completion of the carbonization.A lubricant to be spread on the oven floor of a coke oven carbonization chamber before supplying coal thereto, which has a pyrometric cone equivalent of SK12 or higher and is composed of ceramic spheres, the major part of the spheres having a particle diameter of 1-15 mm. It is desirable that the inclination angle of the aforesaid lubricant, at which the lubricant having been in the stationary state starts to move, is 10^o or below.
