Problems solved by technology
The following problems exist in the use of intermediate frequency electric furnaces: Nowadays, high temperatures are generated during the use of intermediate frequency electric furnaces. The body of the electric furnace will be damaged by the high temperature after long-term use. In severe cases, it will cause harm to the user. The use effect of the device is poor, and it cannot continuously cool down the electric furnace at a certain time interval
The invention with the patent number CN211120614U proposes an IGBT intermediate frequency electric furnace diversion device, which drives the fixed plate to move downward through the hydraulic cylinder at a certain interval, and the sliding plate is moved downwards under the action of the support wheel on the inner wall of the mounting frame during the movement of the fixed plate. The inner side moves, and then the sliding plate compresses the support spring, so that the openings of the first fitting port and the second fitting port are aligned, thereby starting the diversion effect. However, this invention can only conduct diversion cooling to the bottom of the intermediate frequency electric furnace, and cannot The outer side of the intermediate frequency electric furnace is effectively diverted to cool down, the cooling effect is obvious and the effect is poor, and the spring is used as the reset part. After the spring is used for a long time, the elastic force changes significantly, and the aging will affect the normal use of the device. lower sex

The invention discloses an IGBT medium-frequency electric furnace flow guiding device. The flow guiding device comprises a gear box, a flow guiding box and an electric furnace; a hanging rib is arranged on the inner side of the flow guiding box; a hanging frame is hung on the hanging rib; the electric furnace is arranged at the top end of the hanging frame; an upper flow guiding opening is formedin the middle of the top end of the gear box and communicates with the interior of the flow guiding box; and an upper flow guiding pipe communicating with the upper flow guiding opening is arranged inthe gear box. The flow guiding box is arranged, during use, the electric furnace is placed on the hanging frame in the flow guiding box, the electric furnace is located in the middle of the inner side of the flow guiding box, the outer side of the electric furnace is in clearance connection with the inner side of the flow guiding box, the outer side flow guiding effect of the electric furnace isachieved, and compared with a traditional flow guiding device, the flow guiding device has the advantages that the flow guiding range is more comprehensive, and the flow guiding and cooling effect iseffectively improved.
Description
technical field [0001] The invention relates to the technical field of electric furnace equipment, in particular to an IGBT intermediate frequency electric furnace guide device. Background technique [0002] Intermediate frequency electric furnace is a power supply device that converts power frequency 50HZ alternating current into intermediate frequency (above 300HZ to 1000HZ). The intermediate frequency electric furnace heating device has the advantages of small size, light weight, high efficiency, excellent thermal processing quality and favorable environment. Coal furnaces, gas furnaces, oil furnaces and ordinary resistance furnaces are a new generation of metal heating equipment. The following problems exist in the use of intermediate frequency electric furnaces: Nowadays, high temperatures are generated during the use of intermediate frequency electric furnaces. The body of the electric furnace will be damaged by the high temperature after long-term use. In severe cases...
