Operation method of blast furnace wall structure and the blast furnace

摘要

PROBLEM TO BE SOLVED: To provide a structure for furnace wall in a blast furnace and a method for operating the blast furnace with which even in a position using a copper or a copper alloy-made stave cooler, the variation in the furnace an be estimated at once.;SOLUTION: The structure for furnace wall in the blast furnace, which forms the furnace body by fitting the stave cooler on the side wall of the blast furnace body, has the features that plural cast iron-made ribs 1 are disposed on the circumference of an inner peripheral surface of the furnace wall at a prescribed interval and the longitudinal length of these ribs 1 is oriented to the furnace height direction, and pressure gages 6 for detecting the pressure in the furnace and thermometers 5 for detecting the temperature of the cast iron-made rib are embedded into the ribs 1. The method for operating the blast furnace has the features that the condition in the furnace is estimated by measurements of the pressure gages 6 and the thermometers 5 embedded in the cast iron-made ribs 1 disposed in the inner peripheral surface.;COPYRIGHT: (C)2002,JPO
