In the sintering process of the soft magnetic ferrite, the glue discharging process is a very critical link in the product sintering process. When the soft magnetic ferrite is pressed into a compact, in order to increase the mechanical strength and density of the product, a certain amount of binder (PVA), stearate zinc and the like are usually added into the material as additives to increase the binding force of the particles. These substances must be completely volatilized before the solid-phase reaction of the product takes place and are discharged out of the kiln, and the process of discharging these additives and water is called a binder removal process.
