Furnace bottom refractory repair method of the converter having a bottom-blown function

摘要

PROBLEM TO BE SOLVED: To repair a local worn part extending in the wide range at a furnace-bottom part in a converter having a bottom-blowing function by high quality lining having uniform and sufficient thickness and excellent durability, at quicker time in comparison with the conventional method.;SOLUTION: This repairing method includes: a process in which slurry is obtained by kneading a repairing raw material for furnace bottom refractory and a resin demonstrating a self-hardening with the chemical reaction; a process in which the whole local worn part is covered with the slurry by charging the slurry toward the local worn part extending in the wide range at the furnace bottom part in the converter from the furnace opening part; and a process in which the slurry covering the whole worn position is hardened with the chemical reaction generated in the slurry.;COPYRIGHT: (C)2011,JPO&INPIT
