The selection of high-quality refractory materials is an important measure to extend the life of blast furnace-magnesia carbon brick price

Under normal circumstances, corundum bricks and silicon carbide series refractory materials used in blast furnace bodies have good results. Microporous carbon bricks, hot-pressed carbon bricks, graphite, and semi-graphite bricks can be used for hearth and furnace bottom, which have good performance, or adopt a complete UCAR system. Microporous carbon brick is combined with ceramic cup technology, graphite material and good cooling system cooperate. It shows good use effect under different blast furnace conditions.

Extending the life of a blast furnace is a comprehensive research problem. The life of a blast furnace is not only related to the material and quality of refractory materials, but also affected by many factors such as cooling equipment, cooling water quality, construction quality, raw fuel conditions, operation level, inspection and maintenance methods, etc. For the longevity of blast furnaces, these aspects must be strengthened and the overall level must be improved. The selection of new high-quality refractory materials is an important measure to prolong the life of the blast furnace. Before selecting refractory materials, the damage mechanism of the blast furnace lining must be analyzed, and measures should be taken according to local conditions, combined with the smelting conditions and economic endurance of the plant, equipped with cooling system, and refractory materials should be selectively used.
