PROBLEM TO BE SOLVED: To provide a manufacturing method of a plate for a slide gate having denseness and excellent corrosion resistance without causing the breakage, etc., of the plate while holding the heat shock resistance even in the case of making apparent porosity to <=10% after firing. SOLUTION: In 90-98 wt.% refractoriness inorganic aggregate containing at least aluminum base and zirconia base raw material and 2-10 wt.% carbon base raw material, 3-8 wt.% (outer ratio) thermal setting resin and 0.5-2 wt.% (outer ratio) aluminum powder composed of scaly flake powder and spherical atomized powder, are added. Silicon powder having 0.33-2 times by wt. of the aluminum powder is added and kneaded and after forming and drying, this formed silicon powder is fired at 1000-1400 deg.C in a non-oxidizing atmosphere. |
