Preparing method for high-performance pouring material
The invention discloses a preparing method for a high-performance pouring material. The high-performance pouring material comprises 20-40 parts of high alumina bauxite with the grain diameter ranging from 0 mm to 1 mm, 10-30 parts of high alumina bauxite with the grain diameter ranging from 1 mm to 3 mm, 10-20 parts of high alumina bauxite with the grain diameter ranging from 3 mm to 5 mm, 15-25 parts of high alumina bauxite with the grain diameter ranging from 5 mm to 8 mm, 15-25 parts of silica powder, 10-35 parts of heat insulating aggregate, 4-9 parts of dolomite, 2-5 parts of tartaric acid, 1-3 parts of explosion-proofing fibers, 1-3 parts of metallic aluminum powder, 1-3 parts of graphite powder, 5-10 parts of gangue, 5-15 parts of mullite bricks, 5-10 parts of zirconite, 3-7 parts of chromium sesquioxide, 3-12 parts of fused magnesia-zirconia materials, 6-15 parts of phenolic resin and 25-45 parts of dense corundum. The preparing method for the high-performance pouring material has the advantages that after burning is carried out, the strength is high, the descending range of the strength is low along with the rising of the heat treatment temperature, the thermal shock resistant performance is good, and the curing time is short.
