A riser tube coating for a cast aluminum alloy includes a coating-riser tube contact layer material and a coating-aluminum liquid contact layer material. The present invention has a coating protection effect to the maximum mainly by designing ratios of ZrO, AlO, ZnO, binders and other materials and a coat drying heat treatment process, and finally realizes effects of protecting a riser tube, being free of aluminum sticking and prolonging a service life.

Riser tube coating for cast aluminum alloy and using method thereof

Disclosed is a casting ladle for casting aluminum alloy in the present application. The casting ladle includes a liner contact layer, a first thermal insulation layer, a second thermal insulation layer, and a housing layer sequentially from inside to outside. The first thermal insulation layer includes first AlOparticles and at least one first oxide particle selected from the group consisting of first SiOparticles, first CaO particles, and first MgO particles. The second thermal insulation layer includes at least one second oxide particle selected from the group consisting of second AlOparticles, second SiOparticles, second CaO particles, and second MgO particles. The second thermal insulation layer has a porosity of 60-75% and a pore size of 2-5 mm.
