Molten metal rabbling furnace

Abstract

The invention discloses a molten metal rabbling furnace which comprises a furnace body, a rotational flow importer and a rotating magnetic field generator. An inlet is formed on the top of the furnace body and an outlet is formed in the bottom of the sidewall of the furnace body, wherein a door is mounted at the outlet. The rotational flow importer in mounted at the inlet of the furnace. The molten metal flows into the inside of the furnace body through the rotational flow importer. The molten metal flows into the furnace body in a way of eddy when flows out of the rotational flow importer. The rotating magnetic field generator is mounted at the periphery of the furnace body and can rotates around the furnace. The molten metal rabbling furnace firstly uses the rotational flow importer to generate the eddy so as to enable the molten metal to have a certain velocity to form the eddy when flowing into the furnace body. The rotating magnetic field generator supplies rotating and changing magnetic fields and uses the electromagnetic theory to enable the induced current to be generated in the eddy of the molten metal and uses the induced current to form electromagnetic force to enable the eddy of the molten metal to be continued. The rabbling of the molten metal can be achieved through the eddy.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a molten metal stirring furnace. Background technique [0002] In the field of metallurgy, melting metal is a very common and important process. The molten metal can be used to cast metal parts of various shapes. In the process of metal melting and casting, the uniformity of molten metal will determine the product quality of subsequent processes. Due to the high melting point and high density of metals, it is difficult to achieve uniformity during melting and transportation, which will lead to insufficient melting of some raw materials, or condensation during transportation. In order to solve this problem, the molten metal needs to be stirred to improve the uniformity of the molten metal. [0003] Stirring equipment in the prior art usually utilizes mechanical stirring, that is, a mechanical device is inserted into molten metal for stirring. Mechanical stirring is likel...

AI Technical Summary

Problems solved by technology

Mechanical stirring is easy to affect the purity of the molten metal due to the need to extend the mechanical device into the molten metal

Another stirring method is vacuum stirring. Although it has little influence on the purity of the molten metal, the cost of vacuum stirring is high and the stirring force generated is not enough.
