Although the steelmaking converter adopts a comprehensive furnace lining method, during use, due to premature damage to the furnace lining, it is necessary to carry out hot repair. The commonly used construction method is the gunning method, and the commonly used refractory material is magnesium gunning material. After the magnesium gunning material is sprayed out from the spray gun, it is heated to a plastic or molten state during the process of reaching the sprayed body. After gunning, it adheres very firmly and has excellent results. The magnesium oxide content of magnesium based gunning material should be greater than 90%, with reasonable particle composition, certain bonding performance, and small shrinkage rate. At low temperatures, it forms high bonding strength through the chemical action of the binder. At high temperatures, it can also form ceramic bonding and firmly adhere to the furnace lining bricks, improving the gunning effect
