Problems solved by technology

However, according to user feedback, mullite cast steel bricks are difficult to meet the requirements of ultra-high temperature resistance, high corrosion resistance, high strength and good thermal shock stability for special alloy steel mold casting. For example, German users want to produce higher High-grade alloy steel is needed, and we hope that merchants will develop, produce and provide higher-grade poured steel brick products

Abstract

The present invention discloses a steel-casting brick for producing high-grade special alloy steel and a production method thereof. The steel-casting brick is prepared through processes of crushing raw materials, preparing mud, molding, drying, firing and pre-delivery inspecting;and comprises components, by weight percentage, 65-75 % of tabular corundum powder; 10-20 % of andalusite fine powder; 5-15 % of alpha-Al2O3 ultrafine powder and 2-3 % of soft clay powder, wherein the tabular corundum powder consists of 50-60 % of tabular corundum particles and 10-15 % of tabular corundum fine powder, the tabular corundum powder contains 98.5 % of Al2O3 or more and 0.5 % of Fe2O3 or less, the andalusite fine powder contains 55 % of Al2O3 or more and 1.0 % of Fe2O3 or less, and the alpha-Al2O3 ultrafine powder contains 99 % of Al2O3 or more. The steel-casting brick provided by the invention can be used as molded steel-casting bricks for special alloy steel with ultra-high temperature resistance, high corrosion resistance, high strength and good thermal shock stability.

Description

technical field [0001] The invention belongs to the field of high-quality shaped refractory products of refractory materials, and in particular relates to a poured steel brick for producing high-grade special alloy steel. Background technique [0002] At present, most of the cast steel bricks used in the production of alloy steel are mullite cast steel bricks. Mullite cast steel bricks are made of high-quality bauxite as the main raw material, and a small amount of mullite and alumina are first introduced into the matrix of the bricks. And kaolin, the production process is as follows: raw material crushing - mud preparation - molding - drying - firing - inspection - storage - delivery. The production method has easy-to-obtain raw materials, relatively low production cost, strong corrosion resistance and good thermal shock stability. However, according to user feedback, mullite cast steel bricks are difficult to meet the requirements of ultra-high temperature resistance, hig...
