Summary:The invention relates to a method for preparing AZ91D magnesium alloy semi-solid sizing agent by rotating pouring, which is characterized in that AZ91D magnesium alloy is melted and refined in a smelting maintaining furnace, then cooled to 630-650 DEG C, and insulated for 10-30 minutes; a stainless steel rotating pouring tube is preheated to 60-80 DEG C, with the rotating speed of the pouring tube controlled at 0-105r/min, and the inclination of the rotating pouring tube being 20-30 degrees; then the AZ91D magnesium alloy melt is poured into the rotating tube through a deflection tube; a crystallizer is preheated to 470-500 DEG C; the AZ91D magnesium alloy melt enters the crystallizer through the rotating pouring tube, and insulated for 5-15 minutes. The method for preparing the AZ91D magnesium alloy semi-solid sizing agent by rotating pouring has a simple device, low cost, convenient operation, high practicality; the prepared AZ91D magnesium alloy semi-solid sizing agent has fine grain organization and even
