Gunning material

Gunning material is made of high-quality fused magnesia sand and high-quality magnesia-calcium synthetic sand as raw materials, through a strict and special particle size ratio, adding a variety of additives and composite binders, and adding recarburizers and additives. Fast self-flow, short sintering time, high sintering strength, fast solidification, erosion resistance, slag erosion resistance, high characteristics. Improve furnace age and effectively reduce molten steel pollution.

Physical and chemical indicators:

(1). Magnesium>65% Silicon>2% Carbon>7% Granularity: 0-5 0-8mm Bulk density:>2.4%. Apparent porosity>28

(2). Magnesium: 80% silicon; <2% carbon>7% particle size:0-5 0-8mm, body density:>2.4% apparent porosity>25
