Product Introduction
The electric furnace spraying material series developed by our company is made of high-quality heavy burned magnesia sand and other alkaline composite materials, mixed with special composite binders and additives through reasonable particle size composition. Good sintering, strong slag resistance, and the rebound rate is small, high adhesion rate, easy to spray repair operation. Can be widely used in the hot zone of electric furnace, ultra-high power electric furnace, slag line, furnace slope, side wall, tapping port and other parts of the hot repair, is to make the furnace lining to achieve uniform erosion, improve the life of the ideal supporting materials.
