Problems solved by technology

The continuous operation of the product cannot be realized, and because the temperature measured by the thermocouple in the furnace is different from the temperature of the smelted product
When the furnace door is opened, the smelted product is often oxidized, which reduces the quality of the product

Embodiment Construction

[0004] The equipment is mainly composed of a transfer chamber, a horizontal gate valve, a horizontal heat-insulating door, a vertical vacuum furnace body, two crucibles heated by medium frequency induction, a hydraulic tiltable mechanism, valves and a vacuum unit. The overall equipment is a vertical structure, and the transfer bin can be fed while smelting, and the upper crucible is smelting while the lower crucible is warmed and purified at the same time. The purified product can be discharged directly from the discharge port of the valve. The purpose of continuous furnace smelting can be achieved by going round and round like this.

Abstract

The invention relates to a continuous vacuum smelting furnace in the vacuum smelting furnace industry; the present vacuum smelting furnace only can realize the primary smelting but not the continuous smelting. The invention is a single-chamber double-crucible dumpable continuous vacuum furnace. The main structure of the invention comprises a transfer chamber and a vacuum furnace-smelting chamber. The transfer chamber can implement the charging while smelting the furnace, and the materials can be directly charged into the smelting furnace by a horizontal gate valve when the horizontal gate valve in the middle is opened. After the smelting furnace finishes the smelting, a hydraulic dumpable mechanism pours the smelted solution into the next crucible which can implement the heat preservation and purification. The upper crucible can implement the charging while smelting, and the lower crucible can implement the discharging through the valve after finishing the heat preservation. Therefore, the purpose of mass production of vacuum smelting furnaces is orderly and continuously realized.

Description

technical field [0001] The invention belongs to the field of vacuum smelting industry, in particular to a single-chamber continuous vacuum smelting furnace. Background technique [0002] The current vacuum smelting furnace is a single-chamber single-crucible heating structure. Generally, the furnace door can be opened after smelting, heat preservation, purification and cooling to take out the smelted products. The continuous operation of the product cannot be realized, and the temperature measured by the thermocouple in the furnace is different from the temperature of the smelted product. When the furnace door is opened, the smelted product is often oxidized, which reduces the quality of the product. Contents of the invention [0003] The invention is a single-chamber double-crucible pourable continuous vacuum furnace. Its main structure is composed of transfer bin and vacuum smelting chamber. The transfer bin can be fed while smelting. There is a horizontal gate valve ...
