Product description
Ramming mix for electric furnace Production Technics: 1.Based on high purified compound dolomite sand and high purified magnesia, 2.Add magnesia iron sand 3.Adding certain quantity of anchoring agent . Production Feature: 1.Easy to sinter ; 2.Strong anti-permeability; 3.High refractoriness; 4.Long service life. Application: Ramming for the slope and bottom of EAF Use method : 1.Spread the material in the bottom with thichness of100mm to 150mm and rammed hard, 2.Clean the surface, repeat the ramming work once again 3.Put a piece of steel sheet on the surface to avoid damage on the surface when putting scrap and hot metal.
