Light burnt magnesia ball
Light burnt magnesia ball is made of magnesium oxide as the main raw material, adding water and binder at the same time, stirring and pressing under high pressure.
Light burnt magnesia ball is mainly used as the composition regulator of converter slag splashing. Because the slag splashing requires proper viscosity and fire resistance, reasonable slag composition is the key to realize the slag splashing.
Generally slag can not be sprayed directly to protect the furnace. A certain amount of magnesia ball is added to adjust the slag. Since MgO is a kind of high melting point mineral, the melting point is 2800℃, the increase of MgO content in slag will increase the viscosity of slag and improve the fire resistance.
The slag is easy to combine with the lining, forming an effective slag protection layer on the lining, improving the life of the lining and reducing the consumption.
