A melting furnace with electromagnetic stirring device

Abstract

The invention relates to a smelting furnace with an electromagnetic mixing device. The smelting furnace mainly comprises an upper molten pool, a lower molten pool and two groups of electromagnetic mixing units, wherein each group is composed of three same electromagnetic mixing mechanisms; the electromagnetic mixing mechanisms comprise hydraulic cylinders, coils, magnetizers, connecting frames andchassis; the upper molten pool and the lower molten pool are connected by virtue of two communicating pipes which are symmetrical from left to right; and the two groups of electromagnetic mixing units are respectively installed in the positions of the two communicating pipes. According to the smelting furnace, the magnetizers are distributed at an array, so that the communicating pipes are surrounded by magnetic fields, and various kinds of molten metal are uniformly mixed; piston rods are controlled by the hydraulic cylinders so as to drive the three electromagnetic mixing mechanisms in eachelectromagnetic mixing unit to alternately swing up and down in sequence, so that the distribution of the magnetic fields around the communicating pipes in the acting positions of the electromagneticmixing units is changed in real time, irregular movement of the molten metal is realized, and the uniform mixing of the various kinds of molten metal is guaranteed.

Description

technical field [0001] The invention relates to a melting furnace, in particular to a melting furnace with an electromagnetic stirring device. Background technique [0002] Smelting is a fire method in which metal materials and other auxiliary materials are put into a heating furnace for melting and tempering, and certain physical and chemical changes occur in the materials in the high temperature (1300-1600K) furnace to produce crude metal or metal enrichment and slag metallurgical process. It is one of the casting production processes and a very important process in metal processing production. [0003] Stirring is a critical part of the melting furnace process. Its purpose is to make the alloy composition evenly distributed and the melt temperature tend to be consistent. After the furnace material is melted, necessary stirring should be carried out to make the temperature in the molten pool rise evenly, which is also conducive to rapid melting. Stirring also reduces l...

AI Technical Summary

Problems solved by technology

This iron stirring tool directly contacts the molten metal, which will increase the iron content in the melt. At the same time, it is easy to bond some organic matter and moisture on the stirring shovel, which will react in the melt and generate hydrogen ions and other harmful substances. elements, seriously affecting product quality

Due to the limitation of the furnace door and stirring tools, the stirring area is small, resulting in uneven stirring, and it is difficult to achieve the uniformity of the alloy composition, resulting in increased energy consumption, low product quality and productivity
