Problems solved by technology

[0004] However, the amount of binder added in the raw materials of the above-mentioned patent refractory bricks is relatively large (about 2-6%). Even if the binder has high temperature resistance, it still partially decomposes in a high temperature environment, thereby leaving Lower porosity, resulting in a reduction in the strength of refractory bricks

Abstract

The invention relates to the field of refractory materials, and discloses a two-component refractory brick and a production method thereof. The brick is produced from a slurry A and a slurry B; the slurry A includes fused chromium oxide, sintered chromium oxide particles, chrome corundum particles, alumina micro-powder, magnesium oxide micro-powder, zirconia micro-powder, yttrium oxide micro-powder, lanthanum and / or lanthanide metal oxide micro-powder, metallic aluminum micro-powder, metallic chromium micro-powder, metallic zirconium micro-powder, metallic yttrium micro-powder, resorcinol diglycidyl ether, sodium dodecyl benzene sulfonate, ethanol and water; and the slurry B includes the fused chromium oxide, sintered chromium oxide particles, chrome corundum particles, alumina micro-powder, magnesium oxide micro-powder, zirconia micro-powder, yttrium oxide micro-powder, lanthanum and / or lanthanide metal oxide micro-powder, metallic aluminum micro-powder, metallic chromium micro-powder, metallic zirconium micro-powder, metallic yttrium micro-powder, a cationic photocuring initiator, tetradecyltrimethylammonium bromide, ethanol and water. The two slurries are adopted to reduce the use amount of a binder and improve the physical properties of the refractory brick.

Description

technical field [0001] The invention relates to the field of refractory materials, in particular to a two-component refractory brick and a preparation method thereof. Background technique [0002] High chrome bricks have the advantages of high refractoriness and mechanical strength, low thermal expansion coefficient, strong wear resistance and slag resistance, and good thermal shock stability, which are incomparable to ordinary refractory bricks. [0003] The applicant's prior patent CN201510023179.7 discloses a metal high chromium brick, which is composed of fused chromium oxide, sintered chromium oxide particles, chromium corundum particles, alumina micropowder, magnesia micropowder, zirconia micropowder, yttrium oxide micropowder, It is composed of lanthanum and lanthanide metal oxide powder, metal aluminum powder, metal chromium powder, metal zirconium powder, metal yttrium powder and binder. The invention also provides a method for preparing metal high-chrome bricks, t...
