Zusammenfassung:PROBLEM TO BE SOLVED: To provide a steel casting preventing sand penetration by using a sand mold, which not resulting in the sand penetration at the complicated parts in the harsh environment thermally, when casting a thick and large size steel casting. SOLUTION: In the sand mold for casting the thick and large size steel casting, the thermally complicated parts, comprises and artificial mullite sand mold compounded with an artificial mullite as a main component. Moreover, the artificial mullite is coated with a washing compounded with a high purity aluminum as a main component not including SiO2.
