Integral Pouring of 1#2300m Blast Furnace Hearth in a Steel Plant in Liaoning


Product Introduction

In March 2013, 1#2300m ³ of a steel mill in Liaoning Province began to deteriorate in furnace type, with damage to steel bricks and cooling walls in furnace throat, high water temperature difference in local cooling walls in Tiekou area, reduced smelting intensity of blast furnace, and increased fuel ratio, which made it impossible to maintain normal production. West China carried out a comprehensive overhaul of the blast furnace body. Through the protective grill, the structural integrity of uneroded carbon bricks was greatly protected, the eroded carbon brick is repaired by using Huaxi high thermal conductivity castable, which shortens the construction period and saves nearly one million yuan in maintenance cost. The side wall of the furnace cylinder is cast as a whole by using Huaxi HX-RJ.
