Neutral Ramming Mass / Mixes


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-erosive attack of molten metal's 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.
