Refractory concrete composition and metallurgical application thereof

摘要: The refractory concrete composition is comprised of 5-20% and preferably approximately 10% a binder consisting silica having grain size lower than 5 mu m between 1 2 an aluminous compound high alumina content with 20 0 in respective proportions from 3 to 7 approximately, which are appropriate obtain mullitization at temperature during the rise. Application making protection linings or moulded objects particularly intended plants for continuous cold injection casting steel.
