The consumption of refractory bricks for steelmaking is very large, and directly affects the life of steelmaking furnace and smelting cost. Therefore, when selecting refractory bricks, in addition to meeting the requirements of the smelting process, it is also necessary to rationally utilize the resources according to their condition and to continuously improve the technology of pumping material calcination and brick-making.
The consumption of refractory bricks for steelmaking is very large, and directly affects the life of steelmaking furnace and smelting cost. Therefore, in the selection of refractory bricks, in addition to should meet the smelting process requirements, but also according to the resource situation, the rational use, and constantly improve the pump material calcination and brick technology, with a view to using the appropriate refractory bricks, to achieve the furnace long life and low consumption.
At present, the refractory bricks used in the lining of oxygen converter furnace are mainly carbon-containing alkaline refractory bricks, such as tar dolomite bricks, tar magnesium dolomite bricks, tar magnesium bricks, magnesium-carbon bricks and various impregnated bricks. In addition, there are refractory spray coating for spraying.
Since the use of oxygen converter steelmaking, countries generally use magnesium and dolomite refractory bricks for furnace lining, or a mixture of the two made of refractory bricks used. The general trend is to improve the purity of raw materials, appropriate increase in magnesium oxide content, improve the density of refractory bricks and increase the residual She carbon content in the direction of the development of refractory bricks for lining of the furnace gradually improve the quality of varieties are also increasing.
