PROBLEM TO BE SOLVED: To improve adhesion and corrosion resistance in a spray material using a natural dolomite clinker for reducing cost. SOLUTION: In the basic spray material, a refractory aggregate composed of 3-40wt.% natural dolomite clinker, <=60wt.% synthetic dolomite clinker, 0.5-7wt.% soft burnt magnesia fine powder having a BET specific surface area of 5-250m<2> /g and the balance other refractory starting material and in which the sum of the natural dolomite clinker and the synthetic dolomite clinker is <=80wt.% and a binder are compounded. |
