METHOD FOR ESTIMATING COKE EXTRUSION LOAD IN COKE OVEN

摘要

PROBLEM TO BE SOLVED: To provide a method for estimating a coke extrusion load in a coke oven, in which method the extrusion load of coke cake can be estimated by a simple method when a projection part exists on the oven wall in a carbonization chamber of the chamber type coke oven and a dry distillation insufficient zone exists in the coke cake owing to combustion failure in a combustion chamber. ! SOLUTION: The method for estimating the coke extrusion load in the coke oven comprises the steps of: forming coke cake test pieces each of which has a non-dry-distilled zone therein and different width of the non-dry-distilled zone; conducting an extrusion test of the coke cake by using an extrusion load measurement unit, in which the projection part is formed on the side wall corresponding to the oven wall in the carbonization chamber of the coke oven; measuring the force required when the coke cake rides over the projection part; preliminarily forming a relationship between the width of the non-dry-distilled
