Refractory material for electric furnace and cause of damage?

Damage reason: metamorphic layer is formed mainly by the high temperature furnace cover and slag splash and the role of working layer caused by erosion and spalling. Smoke hole and electrode arc radiation high temperature and high speed airflow and furnace dust. The furnace wall under high temperature, slag and molten steel corrosion and mechanical wear of steel scrap.In addition the direct radiation of high temperature hot electrode arc. Also under mechanical impact the lining body is mainly affected by erosion and scrap steel and slag of the molten pool and the bottom form. In addition, smelting steel, method of operation, design and construction of the stove.
The top of the aluminosilicate refractory or alkaline refractory bricks to improve the ability of high temperature resistance and slag erosion; with the development of top now ultra high power electric arc furnace using tin not burned magnesia chrome brick;The ordinary electric furnace wall mainly adopts dolomite brick and magnesia brick, magnesia brick, ultra high power electric furnace smelting special steel or magnesia chrome brick and magnesia brick quality;The bottom and the permanent lining made of high purity magnesia brick or magnesite or dolomite brick, working layer adopts magnesite or high-purity magnesia prepared or castable refractory ramming material or a mixture of magnesite or dolomite sand, both made of ramming material.The steel tank adopts high alumina, magnesia, wax stone, carbon or silicon carbide materials, can be built or ramming or vibration pouring construction.

Taurus Refractory ramming mass Factory mainly engaged in professional manufacturer of development, production and sales of the refractory mixture such as melting copper, aluminum and zinc furnace lining. And supply castable refractory for copper smelting, ramming mass for molten copper,fire clay,refractory mortar, refractory cement ,refractory mixture, refractory concrete and silica sand for copper smelting.
