Refractory materials such as converter air bricks

Refractories for ladle generally include ladle and refractory for refining outside the furnace, refractory for electric furnace, refractory for converter, refractory for tundish, refractory for blast furnace, etc. The specific products are ladle breathable brick, electric furnace cover, tundish, etc. Slag retaining wall, pouring material, ramming material, etc.

Refractories for ladle generally include ladle and refractory for refining outside the furnace, refractory for electric furnace, refractory for converter, refractory for tundish, refractory for blast furnace, etc. The specific products are ladle breathable brick, electric furnace cover, tundish, etc. Slag retaining wall, pouring material, ramming material, etc. As a professional manufacturer of breathable bricks, Ke Chuangxin will briefly introduce several types of refractory materials.

The purpose of steelmaking manufacturers using ladle breathable bricks is to remove harmful gases and impurities, adjust ingredients, etc., so that they can complete the basic tasks of steelmaking such as oxygen supply, slagging, stirring, and heating. In addition to the ladle breathable bricks, the refractory materials for ladle and furnace refining also include magnesia carbon bricks, nozzle block bricks, skateboard bricks, spinel castables, magnesia chrome bricks, sliding nozzles, etc. The materials are magnesia carbon, high alumina, sharp Spar, aluminum carbon, etc.

Refractory materials for electric furnaces are mainly electric furnace covers, furnace bottom ventilating bricks, furnace wall side wall gunning materials, tapping fillers, etc. Many manufacturers have relatively high molten iron conversion, and the iron chute used for molten steel is made of refractory materials. . In addition, the electric furnace cover can also be made of castables.

For refractory materials for converters, manufacturers are generally divided into main materials and furnace repair and furnace protection materials. Among them, the main refractory materials mainly include magnesia carbon bricks, burnt magnesia bricks, bottom-blown argon ladle breathable bricks, and slag stoppers. Furnace repair and maintenance materials for the second converter include large-surface repair materials, hand-feed materials, dry gunning materials, carbon-containing gunning materials, taphole repair materials, etc., which are mainly used for repairing.
