METHOD FOR MEASURING LAYER THICKNESS DISTRIBUTION OF CHARGED MATERIAL IN BLAST FURNACE, AND APPARATUS FOR MEASURING LAYER THICKNESS DISTRIBUTION USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring layer thickness distribution of charged materials in a blast furnace, with which the layer thickness distribution along the furnace radial direction from the furnace center to the furnace wall of the charged materials can be precisely obtained in a short period of time, and an apparatus for measuring the layer thickness distribution of charged materials in the blast furnace using the method.;SOLUTION: The method includes: a measuring step; a shaping line deriving step; a correcting step; and a layer thickness distribution deriving step. In the shaping line deriving step, a continuous function F1 for regulating an estimated shaping line 50 is set in advance. This continuous function F1 is a plurality of functions continued in the furnace radial direction, and regulated with a first linear function f11, a first curving function f21, a second linear function f12, and a second curving function f22, lined up from the furnace wall toward the furnace center side. The first primary function f11 is a function where a line regulated by the function is positioned in the vicinity of the furnace wall and is a straight line in the horizontal direction.;COPYRIGHT: (C)2010,JPO&INPIT
