Abstract

The invention provides an atmosphere bell-type furnace, and relates to the technical field of sintering furnaces of electronic products. The atmosphere bell-type furnace comprises a furnace body, wherein a gas outlet communicated with the hearth is formed in the top of the furnace body; gas inlets communicated with the hearth are uniformly formed in the side wall at the bottom of the furnace body in the circumferential direction; a mixing chamber communicated with the gas inlets is arranged at each of the gas inlets; a gas circulating system is further arranged on the furnace body; one end of the gas circulating system is connected with the gas outlet; the other end of the gas circulating system is connected with the each of the mixing chambers; a mixed gas regulating system is also arranged on the furnace body; the mixed gas regulating system is connected with each of the mixing chambers; an oxygen content analysis system is arranged in the furnace body; the oxygen content analysis system is connected with the mixed gas regulating system. According to the atmosphere bell-type furnace, before a mixed gas enters the furnace body, the mixing volume of a nitrogen flow and an air flow is regulated, so that gases entering the furnace body can be mixed uniformly in proportion, and the product can achieve a better sintering effect.

Description

technical field [0001] The invention relates to the technical field of sintering furnaces for electronic products, in particular to an atmosphere bell furnace. Background technique [0002] With the increasing development of electronic products, the requirements for the performance and quality of electronic product components are getting higher and higher, and soft ferrite materials are one of them. The material is more and more inclined to high quality requirements, small batches, short production cycles and other requirements. Compared with the previous pusher furnace, the bell furnace trades time for space, and completes a series of control of atmosphere concentration and ambient temperature in a smaller space. This meets the market requirements of modern ferrite materials such as small batch, high quality and short cycle. [0003] Atmosphere bell furnace series equipment is mainly suitable for high-temperature sintering processes of electronic ceramics (functional cera...
