摘要 |
An improved ramming composition for use in the iron and steel industry includes between 65-80% by weight mullite, 5-15% by weight silicon carbide, 2-5% by weight graphite, 2-6% by weight ball clay, and 5-10% by weight of a binder formed from a dispersion of 15-70% by weight silica in water. The silica binder replaces binders composed of petroleum pitch, clay, or other organic materials. The silica binder causes the ramming composition to have a longer use life, increased strength, and reduced tendency to crack, oxidize or smoke. |
