METHOD FOR ESTIMATING COKE EXTRUSION FORCE AND METHOD FOR REPAIRING COKE OVEN

摘要

In an extrusion force estimation device 1, an oven wall profile acquiring unit 171 measures irregularities on the inner wall surfaces of a carbonization chamber so as to acquire oven wall profiles. A coke shape estimating unit 173 estimates an outer shape of coke that is produced in the carbonization chamber based on the oven wall profiles. A extrusion force estimating unit 175 defines an active state for a side surface position of the coke at which a coke width is smaller than an oven width and defines a passive state for a side surface position of the coke at which a coke width is larger than the oven width based on the oven wall profiles and the estimated outer shape of the coke. Then, the extrusion force estimating unit 175 calculates oven wall friction force for each side surface position of the coke using a previously set apparent Young's modulus of the coke in accordance with definition of the active state or the passive state for the side surface position of the coke so as to estimate the extrusion force based on the oven wall friction force.
