Abstract

The embodiment of the invention discloses a degassing unit for a smelting furnace. The degassing unit comprises a gas outlet pipe, wherein a stator is fixed at the gas outlet pipe; a rotating rotor is arranged in the stator; a pushing part is arranged at the end part of the rotor; the pushing part is provided with a spray nozzle communicated with the gas outlet pipe. According to the degassing unit for the smelting furnace, as the stator and the rotor are arranged at the gas outlet pipe, wherein the rotor can rotate inside the stator, and the pushing part can rotate at a high speed under the action of sprayed gas, so that gas in the degassing unit for the smelting furnace can be uniformly sprayed out, thus gas entering molten metal can be distributed more uniformly, and the degassing rate of the molten metal can be increased.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a degassing device for a smelting furnace. Background technique [0002] In the process of metal smelting, it is often necessary to pass inert gas into the molten metal through the degassing device used in the smelting furnace to remove hydrogen. However, the gas outlet of the current degassing device used in the smelting furnace is directly connected to the furnace, and the gas emitted by the degassing device used in the smelting furnace is not sufficiently diffused, and the hydrogen cannot be removed smoothly, thereby affecting the quality of the molten metal. [0003] To sum up, how to improve the degassing rate in the metal smelting process has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a degassing device for a smelting furnace, so as ...
