METHOD FOR ANALYZING STATE IN DRY-TYPE ZINC SMELTING BLAST FURNACE AND METHOD FOR DISCRIMINATING OPERATIONAL CONDITION IN DRY-TYPE ZINC SMELTING BLAST FURNACE

摘要

PROBLEM TO BE SOLVED: To analyze the inner part by a blast furnace with an ISP method to a dry-type zinc smelting, which can reproduce an actual operation and can follow a change of a state in the furnace according to the change of operational conditions.;SOLUTION: A method for analyzing reactional state in the range, in which the reducing reaction of at least a zinc oxide, a lead oxide and an iron oxide among respective components in sintered ore, is performed as the main reaction by using a computer system, in the blast furnace for dry-type zinc smelting which extracts the zinc from the sintered ore containing at least zinc oxide, lead oxide, iron oxide, calcium oxide and silicon oxide by using coke.;COPYRIGHT: (C)2004,JPO
