Stainless steel die covering slag

Abstract

The invention discloses stainless steel die covering slag. The stainless steel die covering slag is characterized by comprising, by weight, 18.93%-20.87% of clinker, 3.87%-6.56% of sodium carbonate, 4.56%-6.71% of fluorite, 32.53%-39.36% of perlite, 19.39%-20.73% of power plant ash, 7.16%-8.64% of high-aluminum powder, 11.47%-12.78% of feldspar powder, 8.35%-10.78% of amorphous graphite and 1.98%-3.45% of silico-calcium powder. The stainless steel die covering slag has a thermal insulation property, surface solidification of molten steel can be prevented, direction contact between the air andthe molten steel can be effectively isolated, secondary oxidation of the molten steel is avoided, cracks are prevented and the quality of casting blanks is improved.

Description

technical field [0001] The invention relates to a stainless steel mold powder. Background technique [0002] Stainless steel is a tool steel with high hardness, high wear resistance and high heat resistance. Because stainless steel contains chromium, titanium and other easily oxidized elements, it is the most difficult steel type in die casting. At present, the general stainless steel die casting Mold flux needs to be separately added with exothermic agent and thermal insulation agent during use, resulting in complex processing technology and high cost. Contents of the invention [0003] The purpose of the present invention is to provide a kind of stainless steel molding flux. [0004] In order to achieve the above object, the present invention adopts the following technical solutions to realize: [0005] A stainless steel mold mold powder, which is composed of the following components in weight percentage: 18.93-20.87% of clinker; 3.87-6.56% of soda ash; 4.56-6.71% of f...
