Abstract
A coke extrusion force estimation method includes: measuring irregularities on an inner wall surface of a carbonization chamber to acquire an oven wall profile; estimating an outer shape of a coke produced in the carbonization chamber based on the oven wall profile; defining an active state for a side surface position of the coke at which a coke width is smaller than an oven width and defining a passive state for a side surface position of the coke at which a coke width is larger than an oven width based on the oven wall profile and the estimated outer shape; and calculating 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 to estimate the extrusion force based on the oven wall friction force.
