It is put into roller（2）Number heating furnace is heated to 250 DEG C~280 DEG C, and two heating furnaces are incubated 60 minutes~80 minutes, then with
Stove air cooling.
In above-mentioned technical proposal, more specifically technical scheme can also be：In step, carburizing time to 20 minutes~
A waste air operation is carried out at 30 minutes.
Further, surface clean is carried out to each part for being driven metallic bond after step A terminates.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention is all the time carried out each part at classification according to structure and shape to being driven in the heat treatment process of metallic bond
Reason, makes transmission metallic bond not only improve wearability, and is not susceptible to the situation of adhesion, reduces damage, improves the qualified of finished product
Rate.
2nd, the present invention distinguishes running-surface Carburization Treatment in high temperature to each part for being driven metallic bond, makes carburizing uniform,
The hardness, wearability and fatigue resistance of each part are improved, extends the service life of transmission metallic bond；Carburizing tempering terminates
Surface clean is carried out to each part afterwards, to remove the burnt skin formed due to carbon atom due to high-temperature oxydation in each parts surface.
3rd, each part is cooled using oil cooling mode after quenching, oil guard film is formed beneficial in each parts surface, prevents
Oxidation is got rusty；Tempering uses average tempering mode, makes the hardness of each part moderate and uniform, avoids each part from producing Temper brittleness
Property, eliminate stress caused by high-temperature heating.
