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 10o or below.
