MgO and MgO-CaO series dry spray grouts

The product dry molding, construction fast, smooth surface after construction, can effectively reduce the tundish working layer material on the molten steel pollution. The product does not add water during construction, which can greatly shorten the time required for tundish baking, thereby reducing fuel consumption. The service life of magnesium dry material is more than 24 hours, and the service life of magnesium calcium dry material is more than 12 hours. Environmentally friendly magnesium dry vibrating material is characterized by strong slag erosion resistance, no irritating gas during baking, environmental protection, no carbon or hydrogen increase in molten steel during use, and clean molten steel. The material has been used in many steel mills, the effect is remarkable.
