Method for producing converter slugging agent through electrolytic aluminum overhaul slag

The invention discloses a method for producing a converter slugging agent through electrolytic aluminum overhaul slag. The method comprises the steps that firstly, the electrolytic aluminum overhaul slag is classified, electrolyte left after picking out carbon blocks is processed through a ball mill until the particle sizes are 1 mm-5 mm; secondly, vermiculite raw materials are purchased, the vermiculite raw materials comprise, by weight percent, 30%-45% of SiO2, 5%-35% of Fe2O3, less of 20% of Al2O3, 15%-26% of MgO, less of 1% of CaO, a jaw crusher is used for crushing the raw materials into3 mm-5 mm to serve as aggregate during pelletizing; thirdly, the materials are mixed according to the mass percent of 80: 17 to be uniform, and 3% of heavy oil is added to serve as a binding agent; fourthly, the materials are pressed into the 30 mm-50 mm spherical slugging agent through a dry powder ball press machine, and the spherical slugging agent comprises components including, by weight percent, 2%-10% of Fe2O3, les
