Description

Technical Field

[0001] This invention relates to the field of metal processing technology, specifically to a raw material sintering apparatus for precision metal processing. Background Technology

[0002] Metallic materials generally refer to pure metals or alloys used in industrial applications. There are about 70 kinds of pure metals in nature, among which common ones include iron, copper, aluminum, tin, nickel, gold, silver, lead, zinc, etc. Alloys usually refer to materials that are composed of two or more metals or metals and non-metals and have metallic properties. Sintering is a process of heating powder or powder compacts to a temperature below the melting point of the basic components and then cooling them to room temperature in a certain way and at a certain rate. The result of sintering is that the powder particles bond together, the strength of the sintered body increases, and the aggregate of powder particles is transformed into an aggregate of grains, thereby obtaining products or materials with the required physical and mechanical properties.

[0003] Before metal processing, the metal raw materials need to be sintered to aggregate more granular or blocky metals together. In most cases, the nozzles of existing sintering equipment are aimed at the same part, resulting in uneven sintering. Moreover, the temperature received by the metal at the bottom is lower than that of the metal at the top, and the overall sintering time is longer. Summary of the Invention
