Abstract

The invention relates to a castable and particularly discloses an anti-seepage castable which is prepared from the following raw materials in parts by weight: 53-76 parts of flint clay, 13-21 parts ofmagnesia fine powder, 8-14 parts of baryta feldspar powder, 4-10 parts of cement, 2-7 parts of a seepage-proofing agent, 3-9 parts of nanometer potato powder, 4.5-9 parts of potash feldspar fine powder, 1.5-4 parts of silicon carbide, 9-16 parts of calcium hexaluminate, 2.5-7.5 parts of sodium aluminate and 0.1-0.6 part of 2-morpholineethanesulfonic acid. The anti-seepage castable has excellent seepage-proofing performance.

Description

technical field [0001] The invention relates to castables, in particular to an anti-seepage castable. Background technique [0002] The production of large-scale aluminum alloy ingots in the non-ferrous industry, as well as the further processing of aluminum strips, aluminum foils and other products require high precision in the control of aluminum alloy components. As the key equipment of the aluminum alloy deep processing project, the lining material of the large-scale aluminum smelting furnace, especially the lining material used at the bottom of the aluminum inlet inclined groove, the side wall and the throat of the aluminum smelting furnace, plays an important role in controlling the composition of the aluminum alloy. play an important role. Liquid aluminum not only contains elements such as magnesium, silicon and zinc with high chemical activity, but also has excellent fluidity and is easy to penetrate into the furnace lining. The bottom, side wall and lining materia...
