High-temperature-resistant smelting furnace

Abstract

The invention relates to a high-temperature-resistant smelting furnace. The high-temperature-resistant smelting furnace comprises a shell, wherein a heat-resistant layer is arranged between the shell and an inner cavity, a feeding device is arranged on the inner cavity, the feeding device extends to the position above the shell and is fixed through a fixing part, the top of the shell is provided with a ventilation device, the ventilation device extends into the inner cavity, a heat-resistant plate is arranged at the bottom of the inner cavity, the heat-resistant plate is connected to a combustion cavity, and the combustion cavity is connected to a variable-frequency motor; and the variable-frequency motor is fixed to the shell, a plurality of layers of surrounding coils are arranged at the bottom of the shell, current passes through the coils to be connected to the variable-frequency motor, the variable-frequency motor is connected to a vacuum pump, and the vacuum pump extends into the inner cavity through a vacuum pipe. The high-temperature-resistant smelting furnace has the advantages of being simple in structure and easy to operate, the working efficiency and the working precision of the overall structure are effectively improved through use of a controller, errors are reduced, the overall structure is stable and firm, the service time is long, and the comprehensive economic benefit is improved.

Description

technical field [0001] The invention specifically relates to a high temperature resistant smelting furnace. Background technique [0002] The smelting furnace is mainly used to dissolve metal at high temperature to re-prepare metal products such as alloys. Its internal high-temperature gas is directly discharged to reduce the utilization rate, and the cooling cannot be achieved during the ventilation process, so the high-temperature gas is prone to impact , reduce the firmness of the structure. The existing smelting furnaces are mainly heated by coal, which not only wastes resources, but also increases costs. In a long-term high-temperature environment, the temperature is unstable and shortens the service life, which is not conducive to long-term development. Contents of the invention [0003] The object of the present invention is a high temperature resistant smelting furnace to solve the existing technical problems. [0004] In order to achieve the above object, the pre...
