Split type constant magnetic thermal circulation pit furnace

Abstract

The invention provides a split type constant magnetic thermal circulation pit furnace. The split type constant magnetic thermal cycle pit furnace comprises a furnace body with an inner cavity, the inner cavity comprises a heating cavity and a cooling cavity, a heating assembly capable of moving between the heating cavity and the cooling cavity is arranged in the inner cavity, a magnetizing body is arranged on the outer side of the heating cavity, a hearth is arranged in the heating cavity, the hearth is provided with a gas pipe used for vacuumizing the inner portion of the hearth and filling inert gas into the hearth, and a temperature sensing piece and a temperature control assembly are arranged corresponding to the heating assembly. Compared with an existing pit furnace, the split type constant magnetic thermal circulation pit furnace can be rapidly heated and rapidly cooled, automatic temperature control of all heating areas is achieved, materials needing to be magnetized can be machined, and the requirements for high-efficiency machining and production are met.

Description

technical field [0001] The invention relates to a well-type furnace for producing amorphous iron cores, in particular to a split-type constant magnetic heat circulation well-type furnace. Background technique [0002] Pit furnace series equipment is mainly suitable for pre-sintering, sintering and smelting processes of electronic ceramics, rare earth materials, heat-sensitive components and rare metals. Well-type furnaces are generally relatively large, and the space of the furnace core is very large, and the above-mentioned processing materials also have high temperature requirements, and generally require high temperatures. The heating surface of traditional wall heating elements is relatively small, resulting in the temperature Different, it needs a relatively long heat conduction process to make the temperature inside the furnace core uniform. At this time, it is suitable for processing sub-ceramics, rare earth materials, heat-sensitive elements and rare metals. The work...

Well-type furnaces are generally relatively large, and the space of the furnace core is very large, and the above-mentioned processing materials also have high temperature requirements, and generally require high temperatures. The heating surface of traditional wall heating elements is relatively small, resulting in the temperature Different, it needs a relatively long heat conduction process to make the temperature inside the furnace core uniform. At this time, it is suitable for processing sub-ceramics, rare earth materials, heat-sensitive elements and rare metals. The work efficiency is not high, and the production and processing time is long; and there is no The structure that is convenient for rapid cooling of heating components and the annealing treatment of materials in the furnace cannot meet the requirements of high-efficiency processing and production; for materials that require magnetic treatment, there is no corresponding magnetic component, so it cannot be used Production of materials requiring magnetic treatment
