Manufacturing process of magnesium metal refining kettle

Abstract

The invention discloses a manufacturing process of a magnesium metal refining kettle, and belongs to the technical field of casting, so as to solve the technical problems that the magnesium metal refining kettle is difficult to manufacture and the percent of pass is low. In order to solve the technical problems above, according to the technical scheme adopted for the manufacturing process of the magnesium metal refining kettle, the manufacturing process of the magnesium metal refining kettle comprises the step of the manufacturing process of the magnesium metal refining kettle: before pouring, constructing a sand mold of a lower box body, putting the sand mold into lost foam, connecting an upper box body with the lower box body through a bolt, and then exhausting gases in a box body, after the box body is vacuumized, pouring from a pouring gate at the central position of the lower box body, melting the lost foam, meanwhile, continuously vacuumizing, exhausting air in a pouring liquid, cooling and molding. A duckbilled running channel device is particularly adopted for pouring; in the condition that steelmaking procedures are the same, the manufacturing percent of pass of the magnesium metal refining kettles is increased to above 85 percent from below 50 percent by adopting the design of the duckbilled running channel device for the manufacturing process of the magnesium metal refining kettle.

Description

technical field [0001] The invention relates to a manufacturing process of a metal magnesium refining pot, which belongs to the technical field of casting. Background technique [0002] The magnesium metal smelting industry developed relatively late, and it was only in the ascendant after the 1990s. However, technological progress has been relatively slow. In view of the particularity of metal magnesium smelting, especially the particularity and danger of the refining process, and the quality of metal magnesium refining pots has not been well improved in the magnesium industry, which has caused great harm to production. constraints and security risks. The quality problem of the refining pot is mainly the bottom of the pot. The conventional manufacturing method is die casting, which mainly relies on the natural pressure of molten steel to remove air, so it is difficult to completely eliminate the problem of pores in the casting. The smelting of metal magnesium mainly relies...
