Furnace bottom window structure of aluminum melting furnace with bottom agitating device

Abstract

The invention provides a furnace bottom window structure of an aluminum melting furnace with a bottom agitating device. Four upright stiffened plates are sequentially connected end to end to form a square frame support which is welded with a rectangular stainless steel plate, the rectangular stainless steel plate is horizontally welded with a horizontal stiffened plate and longitudinally welded with a longitudinal stiffened plate, and the horizontal stiffened plate and the longitudinal stiffened plate are in mesh arrangement, thus forming an integrated furnace bottom window structure. The furnace bottom window structure has advantages of being capable of improving serviceability of the agitating device, avoiding sagging and deformation of the steel plate of the window after long-time use and reducing risk of equipment in use, novel and reliable structure, no maintenance, being capable of slowing down demagnetization of the agitating device, improving agitating effect of the agitating device and being widely applicable to the aluminum melting furnaces with the bottom agitating devices.

Description

technical field [0001] The invention relates to a bottom structure of an aluminum smelting furnace, in particular to a bottom structure of an aluminum smelting furnace with a bottom-mounted stirring device in the aluminum smelting industry. Background technique [0002] At present, due to industry development and technological progress, domestic and foreign aluminum smelting industries have higher and higher requirements for aluminum smelting equipment. The application of electromagnetic stirring devices and permanent magnetic stirring devices in aluminum smelting furnaces is also increasing. The application of the stirring device in the aluminum smelting furnace can shorten the smelting time, reduce the burning loss of the aluminum melt, non-contact stirring, no pollution of the melt, make the temperature and chemical composition of the melt uniform, greatly improve the quality of the alloy, reduce the A series of advantages such as labor intensity of workers. However, fo...

AI Technical Summary

Problems solved by technology

However, for bottom-mounted electromagnetic stirring devices and permanent magnetic stirring devices, the structural form of the furnace bottom window at the stirring device has always been a problem that plagues the industry.

In the past, a stainless steel plate was directly welded at the bottom window of the furnace. From the actual use situation, aluminum leakage at the stirring window and concave deformation in the middle of the steel plate have occurred on many furnaces.

Especially the aluminum leakage at the stirring window will cause damage to the stirring device and other equipment at the bottom of the furnace
