轻烧镁球是选用普通轻烧镁粉，经混料后压球而制成。轻烧镁球主要用于转炉炼钢，溅渣护炉，能提高转炉炉龄。轻烧镁球的制备是将80%轻烧镁粉加入20%水，放入混碾机进行碾压、搅拌、混合15～2Omin形成混合料，通过皮带输送机送人压球机制备出产品，然后进行堆放。轻烧镁球成品经过48小时阴干并形成强度后，以备销售。

    轻烧镁球用做转炉溅渣护炉的护渣成分调节剂。因为溅渣护炉要求炉渣要有合适的粘度和耐火度，合理的炉渣成分是实施溅渣护炉的关键。一般的炉渣不能直接进行溅护炉，需要加入一定量的氧化镁球进行调节，同时代替白云石的使用，减少渣量，提高炉渣中MgO的含量。

    由于氧化镁是高熔点矿物，熔点2800℃，炉渣中氧化镁含量的提高，使炉渣粘度变大，耐火度提高，炉渣更容易与炉衬结合在一起，在炉衬上形成有效的炉渣保护层，从而提高炉衬寿命，降低消耗。

Light-burned magnesium balls are made from ordinary light-burned magnesium powder, which are pressed after mixing. Light-burned magnesium balls are mainly used in converter steelmaking and slag splashing to protect the furnace, which can increase the converter age. The light-burned magnesium ball is prepared by adding 80% light-burned magnesium powder to 20% water, putting it into a mixer, rolling, stirring, and mixing for 15 to 20 minutes to form a mixture. The product is prepared by a ball conveyor and a ball conveyor. And then stack them. The light-burned magnesium spheres are ready for sale after 48 hours of over-drying and strength.

    Light-burned magnesium balls are used as slagging component regulators for converter slag splashing protection furnaces. Because the slag splashing furnace requires proper slag viscosity and fire resistance, reasonable slag composition is the key to the slag splashing furnace. General slag can not be directly splash-protected. It is necessary to add a certain amount of magnesia balls for adjustment, and instead of using dolomite, reduce the amount of slag and increase the content of MgO in the slag.

    Because magnesium oxide is a high-melting point mineral with a melting point of 2800 ° C, the increase in the content of magnesium oxide in the slag makes the slag viscosity greater and the fire resistance improved. The slag is more easily combined with the lining, and an effective slag protective layer is formed on the lining, thereby Improve furnace lining life and reduce consumption.
