COIL FOR MEASUREMENT OF INSIDE OF BLAST FURNACE, AND METHOD AND APPARATUS FOR MEASURING MIXING DEGREE OF CHARGED RAW MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a coil for measurement of the inside of a blast furnace that has durability and can be manufactured at low cost in use in the blast furnace, and to provide a technique for measuring a mixing degree of a charged raw material using the same.;SOLUTION: The coil 30 for measurement disposed in the blast furnace 10 includes: a bobbin 32 configured by a refractory whose center is hollow; a metal wire 34 with heat resistant coating that is wound outside the bobbin 32; a heat resistant resin 36 for fixing the metal wire 34 to the bobbin 32; and an insulation material cover 38 covering an outer peripheral surface of the coil. The coil is used to measure a mixture ratio of cokes and sintered ore in the charged raw material.;COPYRIGHT: (C)2013,JPO&INPIT
