The degreasing and pre-sintering integrated furnace is a piece of equipment that combines the two process steps of degreasing and pre-sintering, primarily used for processing a variety of materials, including powder metallurgy materials, high-temperature alloys, cemented carbides, and magnetic materials. The following is a detailed introduction to the degreasing and pre-sintering integrated furnace:

I. Application Industries

In the iron and steel metallurgy industry, it is widely used in the production of high-strength steels, alloy steels, stainless steels, and other materials. Heat treatment can enhance the hardness, strength, and wear resistance of steel, thereby extending its service life. Moreover, integrated pre-sintering furnaces that combine degassing, degreasing, and pre-sintering with heat treatment can effectively remove impurities and oxides from steel, improving its purity and crystallinity and further elevating its quality.  

In the automotive manufacturing industry, heat treatment is primarily employed in the production of components such as automobile engines, transmissions, and chassis. Through heat treatment, the strength, toughness, and corrosion resistance of these components can be enhanced, while their fatigue resistance and resistance to deformation are also improved. Furthermore, integrated pre-sintering furnaces that combine degassing, degreasing, and pre-sintering with heat treatment can refine the material’s microstructure, resulting in superior mechanical properties and wear performance. 2

In the aerospace industry, heat treatment is extensively employed in the manufacturing of critical components such as aero-engines and aircraft structural parts. It enhances the high-temperature strength, creep resistance, and stress-corrosion resistance of these components, thereby ensuring their safety and reliability under extreme operating conditions. Moreover, integrated pre-sintering and heat-treatment furnaces that combine degassing, debinding, and pre-sintering enable precise control over material microstructure and phase transformations, resulting in superior high-temperature oxidation resistance for the final components. 2

In the electronic device manufacturing industry, it is primarily used in the production of semiconductor devices and electronic components. The integrated furnace for degassing, debinding, and pre-sintering also enables precise control over grain boundaries, crystal defects, and the distribution of electronic states, thereby enhancing the material’s electronic properties and conductivity. 2

        II. Functional Features

1. Integrated Design: The integrated debinding and pre-sintering furnace combines the two processes into a single piece of equipment, eliminating the need for repeated handling of products in conventional processes and thereby enhancing production efficiency and product quality.

2. Temperature Field Uniformity: Advanced thermal field control technology is employed to ensure uniform temperature distribution in both the degreasing and pre-sintering stages, thereby promoting consistent product quality.

3. Effective degreasing and grease collection: Equipped with a dedicated degreasing sealed furnace chamber and a grease trap, this design effectively reduces contamination on the inner furnace walls, insulation shields, and heating elements, thereby enhancing the efficiency of degreasing and grease collection.

4. Isostatic sintering: During the pre-sintering stage, constant-pressure control is employed to suppress metal volatilization and enhance the densification and quality of the final product.

        III. Scope of Application

Integrated degreasing and pre-sintering furnaces are widely used in the following fields and for the following materials:

  Powder metallurgy: includes MIM Stainless steel, Prime Minister Degreasing and sintering of stainless steel and other products.

  Superalloys and Cemented Carbides: Used for degreasing and pre-sintering treatments of materials such as superalloys and cemented carbides.

  Magnetic materials: Suitable for degumming and pre-firing processes of magnetic materials such as ferrite magnetic sheets and other electronic components.

  Advanced ceramics: used in tape casting, injection molding, 3D Debinding and degassing processes for advanced ceramic materials produced by tape casting and dry pressing.
