Problems solved by technology

[0003] However, the general metal casting sub-furnace slag removal method has the following defects: a small amount of slag will remain in the metal solution, which cannot effectively improve the quality of the metal solution; sticky slag will remain on the inner wall of the furnace, which will easily cause damage to the furnace after a long time. Therefore, it is necessary for us to design a sub-furnace slag removal method for metal melting and casting.

Abstract

The invention discloses a sub-furnace slag removal method for metal casting. The method comprises the steps of firstly, preparing of a slag removal agent, secondly, throwing of the slag removal agent,thirdly, slag collection, fourthly, slag removal, and fifthly, in-furnace bonded slag treatment. In the first step, components including, by mass percent, 30%-40% of silicon dioxide, 20%-30% of aluminum oxide, 20%-30% of sodium chloride, 10%-15% of calcium fluoride and 10%-15% of sodium fluosilicate are selected and are weighed according to the mass percent sum being 100%, weighed raw materials are put into a screening machine to be crushed and screened, and the slag removal agent is prepared. According to the sub-furnace slag removal method, slag is effectively treated, the quality of a metal solution is improved, bonded slag in a smelting furnace can be treated conveniently, the smelting furnace can be protected effectively, and the service life of the smelting furnace can be prolonged.

Description

technical field [0001] The invention relates to the technical field of metal melting and casting, in particular to a method for removing slag in a sub-furnace of metal melting and casting. Background technique [0002] Metal melting and casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification, and cleaning, a casting with a predetermined shape, size and performance is obtained. The casting blank is almost formed. The aim of no machining or less machining reduces cost and to some extent time. [0003] However, the general metal casting sub-furnace slag removal method has the following defects: a small amount of slag will remain in the metal solution, which cannot effectively improve the quality of the metal solution; sticky slag will remain on the inner wall of the furnace, which will easily cause damage to the furnace after a long time. So it is necessary for us to design a sub-furnace s...
