Problems solved by technology

[0002] HAK-2 diffusion pre-alloyed Fe-Mo-Cu-Ni powder is an iron-based powder, which is widely used in iron-based powder metallurgy high-strength structural parts, such as transmission parts of automobiles, motorcycles, tractors, machine tools, and textile machines At present, this type of powder is mainly imported from Canada, its brand is DB46, and at least 3,000 tons are imported every year; while the existing domestic production process of this iron powder is relatively cumbersome, the production line is long, the composition is difficult to control, and the quality fluctuates greatly. The formability and compressibility of the powder are poor, and the compression density of the DB46 powder can reach up to 7.05g / cm 3

Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like figure 1 As shown, the HAK-2 diffusion pre-alloyed Fe-Mo-Cu-Ni powder production process of the present invention includes the following steps from left to right: raw material mixing, FT treatment, treatment powder mixing, comprehensive treatment, crushing, sieving Sorting, batching, lubricant mixing, product packaging, among which,

[0023] 1) Mixing of raw materials: using a three-dimensional mixer to mix iron powder and black molybdenum powder into mixed raw materials, the mixing time is 30-60 minutes, and the mass percentage of black molybdenum powder is 0.3%-2%;

[0024] 2) FT treatment: use a reduction furnace to process mixed raw materials, the furnace...

Abstract

The invention discloses an iron-based powder production process and particularly relates to an HAK-2 diffusion prealloying Fe-Mo-Cu-Ni powder production process. According to the HAK-2 diffusion prealloying Fe-Mo-Cu-Ni powder production process, the hardness of power after sintering is 3 RB more than that of DB46, the compressibility is higher by 0.05g / cm3, a production route is short, and ingredients, process parameters and product quality are easy to control. The HAK-2 diffusion prealloying Fe-Mo-Cu-Ni powder production process sequentially comprises the steps of raw material mixing, FT treatment, treated powder mixing, comprehensive treatment, breaking, screening, blending, lubricant mixing and product packaging from left to right.
