Abstract

The invention relates to a refractory material for steel making, particularly a metal composite low-carbon magnesium-carbon composite material. The metal composite low-carbon magnesium-carbon composite material is prepared by carrying out pressure molding on the following components in percentage by weight: 85-95% of magnesite, 2.0-4.5% of graphite, 1.0-6.0% of metal steel fiber, 0.5-2.0% of phenol formaldehyde resin and 1.5-5.0% of metal deoxidizer. The metal deoxidizer is composed of metal aluminum powder and silicon powder in a ratio of 2.0:1-3.0:1. The composite material enhances thermal shock stability and high-temperature strength of the low-carbon magnesium-carbon brick.

Description

technical field [0001] The invention relates to a refractory material for steelmaking. Background technique [0002] With the continuous progress of the society and the rapid development of the iron and steel industry, the requirements for the quality of steel varieties are continuously improved, making the working conditions of various refining furnace linings tend to be high temperature, the heat load time is prolonged, combined with oxygen blowing, argon blowing and vacuuming, Especially in the case of smelting low-carbon steel, ultra-low carbon steel and killed steel, the commonly used magnesia-chrome bricks, alumina-magnesia-carbon bricks, magnesia-dolomite bricks, castables, ordinary magnesia-carbon bricks, etc., can no longer meet the requirements of steel Quality improvement and smelting speed requirements. [0003] At present, refining furnace steelmaking is also known as out-of-furnace refining, and there are more than 30 methods, among which DH, RH, AOD, VOD, LF,...
