Description

technical field

[0001] The invention relates to the technical field of dewaxing equipment, and specifically discloses a dewaxing pre-burning furnace. Background technique

[0002] The pre-sintering furnace is a heat treatment furnace that can provide materials with a specific temperature, a specific environmental pressure and a vacuum degree. The pre-sintering furnace generally includes a vacuum device, a heating and heat preservation device, a process gas device, a cooling device, a control device and a dewaxing device. Among them, the dewaxing device is used to collect the molding agent added to the product. In order to make the product shape better, a molding agent is generally added to the product, but if the molding agent stays in the product, it will affect the quality of the product. The molding agent will be in a gasified state at high temperature, and the gasified molding agent will move directionally by blowing or pumping, and the molding agent will be recovered a...
