Abstract

The invention discloses a yield and efficiency increasing method for smelting rough metal magnesium by a Pidgeon process, and aims to provide a more effective new yield and efficiency increasing method for smelting rough magnesium. According to the technical scheme, high-quality magnesium clinker is adopted, a quality analysis method is changed, and a new production formula of the high-quality magnesium clinker is designed. The ratio of raw materials to the magnesium is reduced, and the yield of the rough magnesium in a single tank and profit are improved. The method is a unique method for improving a process technology for smelting the magnesium by the Pidgeon process in future.

Description

technical field [0001] The invention relates to a new magnesium smelting method which utilizes three raw materials of high-quality magnesium clinker, ferrosilicon and fluorite according to the weight ratio to formulate ingredients, as the crude magnesium smelting charge of the Pidgeon process. More specifically, it is a new smelting method that uses high-quality magnesium clinker to replace the low-quality calcined dolomite used in current production to increase the output and profit of a single pot of crude magnesium. Background technique [0002] At present, the traditional smelting process for the production of crude magnesium metal by the Pidgeon method is to use calcined white, ferrosilicon, and fluorite after dolomite roasting. The pellets used for smelting are loaded into a horizontal stainless steel vacuum reduction tank and heated to 1200°C in a reflection heating furnace. After the magnesium oxide is reduced, magnesium vapor is released, and the magnesium vapor is ...
