A particulate quick-setting refractory composition for monolithic linings of metallurgical vessels comprising, by weight, from about 80 to 98 percent basic refractory aggregate, from about 0.5 to 4 percent glassy silicate, from about 0.5 to 3 percent calcium oxide and from about 1 to 5 percent glassy alkali metal polyphosphate, with optionally up to about 4 percent chromic oxide exclusive of any contained in the basic refractory aggregate, up to about 6 percent clay and up to about 6 percent carbon. The monolithic lining suitably replaces the entire refractory brick lining of steelmaking vessels such as the cone section of the basic oxygen furnace. |
