FURNACE REFRACTORY PRODUCT LIFE PREDICTION METHOD

摘要

PROBLEM TO BE SOLVED: To accurately predict the life of a refractory product bonded in a furnace such as a blast furnace, a converter or a heating furnace.;SOLUTION: A furnace refractory product life prediction method of the present invention is a furnace refractory product life prediction method for detecting a wear state of a refractory product by measuring a surface shape of the refractory product lined in a furnace body and predicting a life of the refractory product based on the detected wear state of the refractory product, comprises acquiring a three-dimensional shape of a furnace inner wall obtained by being measured right after a repair of the furnace body as reference data; acquiring a three-dimensional shape of the furnace inner wall obtained by being measured after operating the furnace body as operation data; and determining a wear speed of the refractory product from a difference between the reference data and the operation data, and predicting the life of the refractory product based on the wear speed of the refractory product and an operation condition of the furnace body.;COPYRIGHT: (C)2016,JPO&INPIT
