Slag 30 Slag Remover is a type of flux used in the steel industry to remove impurities, such as slag, from the surface of molten metal. It is made from a blend of mineral components, such as fluorite, lime, and silica, that help to break down and dissolve the slag, allowing it to be easily skimmed off the surface of the molten metal.Slag 30 Slag Remover is designed to be used with a variety of different types of steel, including carbon steel, stainless steel, and alloy steel. It is typically added to the molten metal in a controlled manner, and then stirred to ensure even distribution. As the slag begins to dissolve, it rises to the surface of the molten metal, where it can be skimmed off using specialized equipment.
