Neutral Ramming Mass

This refractory mix is high alumina mix where in predominant aggregate component of alumina imparts a strong skeleton aggregate structure of superior uniform heat stability. The refractory mix is characterized by an ability to withstand corrosive-errosive attack of molten metals and their acids, semi basic and basic slags during repeated exposure thereto together with excellent volume stability, superior structure heat stability, low apparent porosity, a high contact angle with molten steel and strong abrasion resistance Matrix.
The refractory mix is produced by selecting specific fractions of alumina grains used in high performance refractories along with various Chrome compounds, combination of special clays, as tackifying agents are used, which has good plasticity ,does not swell in water, stands high temperature along with binder to increase strength of the lining at elevated temperatures. Importance of bulk density is always considered and maintained for which different fractions of components are used in the matrix.
