Abstract: 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, Al2O3, 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.

Abstract: A purification method of a recovered aluminum melt for an automobile hub includes nitrogen degassing of a gas permeable brick pouring ladle bottom layer arranged on a lower portion of a gas permeable brick pouring ladle and argon degassing of a rotor degasser arranged on an upper portion. The invention has a good degassing and deslagging effect and high purification efficiency, and achieves energy conservation and environmental protection.
