Abstract
The invention discloses a kind of heat treatment process of cutting disc, include the following steps：1) cutting disc is preheated to 600 650 DEG C by heating furnace；2) cutting disc after preheating is quenched, hardening heat is 1,050 1100 DEG C, and quenching is put into impregnate 3 hours in aviation kerosine and be cooled down after 1 hour；3) it cutting disc after cooling will be quenched is put into tempering furnace and be tempered, temperature is 400 420 DEG C, is put into impregnate 3 hours in machine oil after tempering and is cooled down；4) cutting disc after cooling will be tempered and is heated to 1,100 1200 DEG C in a vacuum with the heating speed of 400 DEG C/min, put into 180 DEG C of liquid nitrogen and cool down rapidly immediately after；5) cutter after cooling is heated to 250 DEG C, places into natural cooling in quartz sand.
Description
Technical field
The present invention relates to the heat treatment process of cutting disc.
Background technology
The toughness of currently used cutting disc, hardness and wearability are all not ideal enough.
Invention content
The purpose of the present invention is to provide a kind of heat treatment process of cutting disc, can improve toughness, the hardness of cutting disc
And wearability.
To achieve the above object, the technical scheme is that a kind of heat treatment process of cutting disc is designed, including as follows
Step：
1) cutting disc is preheated to 600-650 DEG C by heating furnace；
2) cutting disc after preheating is quenched, hardening heat is 1050-1100 DEG C, and quenching is put into boat after 1 hour
It impregnates 3 hours and is cooled down in empty kerosene；
3) it cutting disc after cooling will be quenched is put into tempering furnace and be tempered, temperature is 400-420 DEG C, after tempering
It is put into impregnate 3 hours in machine oil and be cooled down；
4) cutting disc after cooling will be tempered and is heated to 1100-1200 DEG C in a vacuum with the heating speed of 400 DEG C/min,
It puts into -180 DEG C of liquid nitrogen and cools down rapidly immediately after；
5) cutter after cooling is heated to 250 DEG C, places into natural cooling in quartz sand.
The advantages of the present invention are：A kind of heat treatment process of cutting disc is provided, cutting disc can be improved
Toughness, hardness and wearability.
