Description

Technical field:

[0001] The technical solution to be protected by the present invention belongs to the technical field of casting technology, specifically, it is a casting method of stave with high melting point metal steel as the matrix. Background technique:

[0002] Cooling walls are widely used in steelmaking blast furnaces, launders and other equipment. Compared with the currently widely used nodular cast iron stave, the cast steel stave, as a new generation of blast furnace stave, has the advantages of high elongation, high tensile strength, high melting point, thermal shock resistance and good overall thermal conductivity. The base body of the steel stave is integrated with the cooling pipe, which eliminates the gap between the base body and the cooling pipe in the ductile iron stave, reduces thermal resistance, and thus improves the service life of the blast furnace. The base material of the cast steel stave is low-carbon alloy steel with a high melting point. Gener...
