Problems solved by technology

[0003] The workpiece after demolding needs to be degreased before sintering. The degreasing step requires a lot of energy consumption and produces more waste. It is necessary to simplify the degreasing process, combine multiple steps together, and pass through the gas phase or liquid at the same time Phase degreasing can not be more ideal and rapid degreasing

Abstract

The invention relates to a spraying-type degreasing furnace and a degreasing process. The spraying-type degreasing furnace comprises a furnace body and support plates which are arranged in the furnace body layer by layer in an up-down manner. The spraying-type degreasing furnace is characterized in that a plurality of workpiece grooves are formed in each support plate, a plurality of through holes are formed in each support plate, spraying pipelines communicated with a furnace cavity are arranged on the upper portion of the furnace body, discharging pipelines communicated with the furnace cavity are arranged on the lower portion of the furnace body, and the furnace body is provided with an air way communicated with the furnace cavity. Gas phase and liquid phase alternation degreasing is realized in the same furnace cavity, so that operation steps and energy consumption needed for heating are reduced; gas and liquid can pass the through holes formed in the support plates quite well, so that degreasing uniformity is guaranteed.

Description

technical field [0001] The invention relates to a degreasing furnace and a degreasing process thereof, in particular to a spray type degreasing furnace. Background technique [0002] Powder metallurgy is a process technology for producing metal or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to manufacture metal materials, composite materials and various types of products. Powder metallurgy has similarities with the production of ceramics. Therefore, a series of new powder metallurgy technologies can also be used for the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problems of new materials and plays a pivotal role in the development of new materials. [0003] The workpiece after demolding needs to be degreased before sintering. The degreasing step requires a lot of energy consumption and produces more waste. It is necessary to sim...
