Abstract
The present invention relates to a kind of preparation processes of powder metallurgy auxiliary material, it includes raw material mixing, fusing sintering, Shape correction and finished product packing.Procedure of processing of the present invention is rigorous, high in machining efficiency.
Description
Technical field
The present invention relates to a kind of preparation processes of auxiliary material, and in particular to a kind of preparation process of metallurgical auxiliary.
Background technology
Existing metallurgical auxiliary preparation process, generally existing preparation process is cumbersome, and processing efficiency is low, and production cost is high
The problems such as, do not meet actual production requirement.
The content of the invention
Goal of the invention：The purpose of the invention is to overcome deficiency of the prior art, it is rigorous to provide a kind of procedure of processing,
The preparation process of powder metallurgy auxiliary material high in machining efficiency.
Technical solution：In order to solve the above-mentioned technical problem, the preparation of a kind of powder metallurgy auxiliary material of the present invention
Technique, it comprises the following steps,
（1）By refining slag, iron powder, lime stone, silica according to 10：（5-7）：（2-3）：1 ratio mixing；
（2）Above-mentioned mixture is sent into vacuum drying oven and melts sintering, 1500-1800 DEG C was first heated in 30-50 minutes, heat preservation
20 minutes, 500-600 DEG C was then cooled in 10-20 minutes, 2000 DEG C were finally warming up in 30-45 minutes, heat preservation 10
Room temperature cools down after minute；
（3）Above-mentioned sintering feed is put into trimmer and carries out Shape correction；
（4）Finished product packing.
Advantageous effect：Compared with prior art, the present invention its remarkable advantage is：The procedure of processing of the present invention is simple, each to walk
Suddenly coordinate rigorous, effectively improve processing efficiency, production cost is low, meets actual production requirement.
Specific embodiment
With reference to embodiment, the present invention is further illustrated.
