Description

Technical Field

[0001] The utility model belongs to the technical field of alloy co-penetration equipment, in particular to a long rod multi-element alloy co-penetration equipment. Background Art

[0002] The multi-element alloy co-penetration process is used to treat the surface of metal parts, which can significantly improve the surface corrosion resistance of metal parts and is widely used in products such as thin plates and standard parts. At present, the multi-element alloy co-penetration process is usually carried out by the powder method. Specifically, the metal parts, multi-element alloy powders and additives are placed in a furnace pot, and a heating furnace is used to heat and raise the temperature during the rotation process. After a certain process time, the furnace pot is taken out of the heating furnace, and then the workpiece is taken out of the furnace pot.

[0003] For small metal parts, the aforementioned multi-element alloy co-infiltration process is easier to carry out, because small metal parts occupy a small volume and are easier to put into and take out of the furnace tank. However, for metal parts such as long rods, there are many inconveniences during the co-infiltration process. First, due to the long size of the long rod, the size of the furnace tank is also relatively long, which makes it difficult to put the long rod into and take out of the furnace tank; secondly, the longer furnace tank requires an extended heating furnace, so the furnace cover that is suitable for the heating furnace is also heavier. Due to the lack of a suitable control structure for opening and closing the cover, it is more time-consuming and laborious to put the furnace tank in before the process and take it out after the process.

[0004] In summary, it is necessary to develop and design a new type of long rod multi-element alloy co-infiltration equipment to solve the above-mentioned technical problems. Utility Model Content
