Vacuum furnace wire-feeding device

Abstract

The invention provides a vacuum furnace wire-feeding device. The vacuum furnace wire-feeding device comprises a drive device and a transmission device, wherein the drive device comprises a counter, amotor and a speed reducer; the transmission device comprises a transmission shaft, a drive wheel and a pressing wheel; the counter is mounted on the motor, and is used for obtaining rotation times ofa rotor of the motor; the rotor is connected to the input shaft of the speed reducer; the output shaft of the speed reducer is connected to one end of the transmission shaft; the drive wheel is connected to the other end of the transmission shaft; the pressing wheel is adjacent to the drive wheel; and a transmission channel is defined between the pressing wheel and the drive wheel. The wire-feeding device provided by the invention can precisely control wire feeding amount, and is simple and convenient in operation.

Description

technical field [0001] The invention relates to a wire feeding device, in particular to a wire feeding device for a vacuum furnace. Background technique [0002] Nowadays, when producing alloys in the metallurgical industry, in order to reduce the impact of harmful gases on product quality, vacuum furnaces are usually used for smelting production. [0003] At present, there are mainly two feeding methods in the vacuum furnace. One is to directly add the required smelting materials into the melting furnace of the vacuum furnace at one time for smelting production. The other is to put some materials into the melting furnace of the vacuum furnace first, put some materials that need to be put into the silo in different procedures, and put them into smelting production. During the production process, the materials in the hopper are put into the hopper through the funnel in stages In the melting furnace, although this feeding method can be fed in different steps, it cannot meet t...

Problems solved by technology

[0003] At present, there are mainly two feeding methods in the vacuum furnace. One is to directly add the required smelting materials into the melting furnace of the vacuum furnace at one time for smelting and production.

The other is to put some materials into the melting furnace of the vacuum furnace first, put some materials that need to be put into the silo in different procedures, and put them into smelting production. During the production process, the materials in the hopper are put into the hopper through the funnel in stages In the melting furnace, although this feeding method can be fed in different steps, it cannot meet the production requirements that require precise control of the feeding time and amount.

Because the vacuum furnace is a closed space, the temperature inside is high and the environment is complex, especially the electromagnetic induction inside the vacuum induction furnace is strong, so there is currently no suitable feeding device that can be used in the vacuum furnace
