Aluminum bronze continuous casting furnace based on electromagnetic stirring and autonomous stirring

Abstract

The invention discloses an aluminum bronze continuous casting furnace based on electromagnetic stirring and autonomous stirring, and relates to the technical field of continuous casting. The aluminumbronze continuous casting furnace based on electromagnetic stirring and autonomous stirring comprises a furnace body, an electromagnetic stirrer, an ultrasonic generator arranged at the upper part ofthe furnace body and a high-temperature graphite conduction mechanism, wherein the electromagnetic stirrer is fixedly installed at the front position where melt of the furnace body is discharged, andthe ultrasonic generator is installed at the top of the furnace body and transmits energy to the end part of a graphite sleeve at the top. According to the aluminum bronze continuous casting furnace based on electromagnetic stirring and autonomous stirring, the structure is refined and uniformed through electromagnetic stirring during solidification, so that formed impurities with relatively lightdensity can be removed at the fusion end through ultrasonic waves, and a high-quality casting blank which is low in impurity content, low in oxygen content and uniform in structure can be produced.

Description

technical field [0001] The invention relates to the technical field of continuous casting, in particular to an aluminum bronze continuous casting furnace based on electromagnetic stirring and autonomous stirring. Background technique [0002] Continuous casting technology has played a vital role in the development of the contemporary iron and steel industry. Compared with traditional techniques, it has the effects of simplifying the production process, increasing metal yield, saving energy consumption, reducing labor force and improving the quality of casting slabs. As an auxiliary means to improve steel productivity, electromagnetic stirring was first applied to the continuous casting process of steel. Electromagnetic stirring technology can greatly improve the cleanliness of steel, reduce subcutaneous pores, expand the equiaxed grain area of ​​slab, and reduce composition segregation and Superheat, while electromagnetic stirring is also suitable for aluminum bronze.

AI Technical Summary

Problems solved by technology

[0003] When electromagnetic stirring is used to stir the aluminum bronze liquid, the precipitated impurities and copper slag are suspended in the copper liquid. Under the influence of the density of the copper liquid, the impurities and copper slag cannot float to the liquid surface by themselves. It can remove more impurities and copper slag, but it cannot fully consume or decompose the impurities and copper slag in the copper liquid. Therefore, it is necessary to collect and treat the suspended impurities and copper slag in the copper liquid to ensure the further improvement of the billet quality.

[0004] Such as the Chinese authorized patent publication number is (CN 206862111 U) a kind of vacuum consumable electrode arc melting furnace, including crucible, control box, electrode lifting mechanism, electrode rod, electrode chuck, consumable electrode, furnace shell, pumping The vacuum mechanism and the water cooling mechanism realize self-stirring and impurity removal through the bottom electromagnetic stirrer and the side wall electromagnetic stirrer. The melting furnace cannot collect and process the impurities suspended in the metal melt after removing impurities by electromagnetic stirring.
