An induction furnace for high-efficiency horizontal continuous casting

Abstract

The invention discloses a high efficiency induction furnace for horizontal continuous casting. The high efficiency induction furnace comprises a furnace body, a tilting system, a water cooling system and an electrical system, wherein the furnace body comprises a shell, an induction body and an accommodating container used for smelting; the accommodating container used for smelting is mounted in the shell; the induction body is formed by coils and comprises an iron core, the coils, a water cooled jacket and an induction body shell; the coils are spaced at equal intervals and fixedly mounted on the iron core; the iron core comprises a lower base and a vertical iron core body; the lower base is fixedly mounted at the bottom of the shell; the vertical iron core body is fixedly mounted on the lower base; the upper end of the vertical iron core body is fixedly connected with the interior of the shell through a bolt; the induction body shell wraps the outer parts of the coils; the shell wraps the outer parts of the induction body and the accommodating container used for smelting; a heat preservation layer is arranged in the shell; and a heat insulation layer is arranged on the outer surface of the shell.

Description

technical field [0001] The invention relates to the field of melting furnace equipment, in particular to an induction furnace for high-efficiency horizontal continuous casting. Background technique [0002] Induction melting furnace is a kind of melting equipment, which is composed of intermediate frequency power supply, capacitor cabinet, furnace body, mechanical tilting device and so on. As a kind of smelting equipment, it has a history of decades in cast copper smelting and double smelting. my country also has rich experience in the manufacture and application of power frequency furnaces and intermediate frequency furnaces. In power structure, frequency conversion technology, integrated control, Remarkable progress has been made in many aspects such as recirculating cooling technology. There are more and more manufacturers using induction melting furnaces and heat preservation, including the famous manufacturer Ningbo Shenguang Furnace Co., Ltd. Features of induction fur...

Problems solved by technology

4) Impact on the environment: the dust of the induction melting furnace is oxide fine particles; strong electromagnetic pollution; the pollution is all in the plant; the induction furnace uses electricity as energy, and the power consumption per ton of copper liquid is about 2160MJ (600kWh)

[0003] However, the melting rate of the current induction melting furnace is relatively small. For this problem, the current method is to increase the overall power by reducing the number of coils; however, this solution will easily cause the local temperature of the induction body of the melting furnace to be too high Resulting in a reduction in the overall life of the device
