Light burnt magnesia ball is made of ordinary light burnt magnesia powder, which is mixed and pressed. Light burnt magnesia ball is mainly used for converter steelmaking and slag splashing protection, which can improve the converter life. The preparation of lightly burned magnesia ball is to add 80% lightly burned magnesia powder to 20% water, then put it into a mixer for rolling, stirring, mixing for 15 to 20 minutes to form a mixture. The product is prepared by a belt conveyor and sent to a ball-pressing machine, and then stacked. The finished product of light burnt magnesia ball is dried in shade for 48 hours and forms strength for sale.

Light burnt magnesia ball is used as slag protection component regulator for slag splashing protection of converter. Because slag splashing protection requires proper viscosity and refractoriness of slag, reasonable slag composition is the key to implement slag splashing protection. Generally, slag can not be splashed directly. It needs to be adjusted by adding a certain amount of magnesia sphere. At the same time, it can replace dolomite to reduce slag volume and increase MgO content in slag.

Magnesium oxide is a high melting point mineral with a melting point of 2800 and the content of magnesium oxide in the slag increases, which makes the slag more viscous and fireproof. It is easier for the slag to be combined with the lining to form an effective slag protective layer on the lining, so as to improve the lining life and reduce consumption.
