Description

Technical Field

[0001] The utility model relates to the technical field of vacuum induction melting furnaces, in particular to a charging chamber based on a vacuum induction melting furnace. Background Art

[0002] A vacuum induction melting furnace is a melting device that melts metal under vacuum conditions through induction heating and then pours the liquid metal into a mold to produce a metal ingot. Existing vacuum induction melting furnaces typically consist of a furnace body, a melting unit housed within it, and a mold. During operation, raw materials must first be placed in the melting unit, the furnace lid closed, and the vacuum device activated to vacuum the interior of the furnace. Once the required vacuum level is achieved, the melting unit is activated to begin melting. This entire process cannot achieve continuous production, making it difficult to meet the current needs of enterprises to improve production efficiency. Furthermore, the addition of materials requires manual labor, which affects the automatic production efficiency of the device, and the inability to add sufficient quantities, which affects the quality of the subsequent melting. Therefore, we have redesigned a feeding chamber for a vacuum induction melting furnace. Utility Model Content
