Description
Technical field
The present invention relates to metal heating processing technology technical field, and in particular to ferrite magnetic member Technology for Heating Processing.
Background technology
Powder part is a kind of that metal dust is compressing by high temperature, high pressure, and then carrying out the handling process such as high-frequency quenching carries out hardness, the heat of toughness
Treatment.Powder part has the advantages that high intensity, high rigidity, high-wearing feature, gradually replaces traditional work in fields such as such as auto industrys at present
The metal parts of skill, the development trend as following metal parts.At present, when carrying out high-frequency quenching to ferrite magnetic member using traditional handicraft, go out
The probability of existing crackle is up to 30% or so, how to reduce it and the probability of crackle occurs, and it is current problem demanding prompt solution to improve product percent of pass.
The content of the invention
It is an object of the invention to provide a kind of process is simple, ferrite magnetic member Technology for Heating Processing that is easy to operate, effectively improving product percent of pass.
In order to solve the problems existing in background technology, the present invention is to use following technical scheme：Ferrite magnetic member Technology for Heating Processing, including it is following
Step：
(1), preheat, the pre-heat treatment, 200~400 DEG C of preheating temperature, 3~5 seconds preheating time are carried out to the ferrite magnetic member；
(2), cool down for the first time, through the ferrite magnetic member after the preheating natural cooling, 1~3 second cool time in atmosphere；
(3), heat, the ferrite magnetic member after being cooled down through the first time is heated in heating furnace, the heating-up temperature is divided into three sections, described the
One section of temperature is 500~600 DEG C, and the second segment temperature is 600~700 DEG C, and the 3rd section of temperature is 700~800 DEG C, described
Heat time is 5~15 minutes；
(4), cool down for second, cooled down in quenching liquid through the ferrite magnetic member after the heating, 4~6 seconds cool times；
(5), finished product packing.
The present invention has following beneficial effect：Ferrite magnetic member Technology for Heating Processing of the present invention, including preheat, cool down for the first time, heat,
The step such as second cooling and finished product packing, wherein, heating-up temperature, the heat time of each step by testing repeatedly, and at heating
The reason stage is divided into three bringing-up sections, to obtain optimal thermal effectiveness, the probability of crackle occurs below 4%, effectively improves product qualified
Rate.In addition, the features such as present invention has process is simple, easy to operate, improve production efficiency, reduces production cost.
