Abstract
The invention discloses a heat treatment process for a disc cutter. The heat treatment process comprises the following steps that 1, the disc cutter is preheated to 600 DEG C-650 DEG C through a heating furnace; 2, the preheated disc cutter is quenched, the quenching temperature is 1050 DEG C-1100 DEG C, and after quenching lasts for one hour, the disc cutter is put into aviation kerosene to be soaked for three hours and cooled; 3, the quenched and cooled disc cutter is put into a tempering furnace and tempered, the tempering temperature is 400 DEG C-420 DEG C, and after tempering is conducted, the disc cutter is put into machine oil to be soaked for three hours and cooled; 4, the tempered and cooled disc cutter is heated to 1100 DEG C-1200 DEG C in a vacuum at the heating speed of 400 DEG C/min, and then the disc cutter is immediately put into liquid nitrogen with the temperature being minus 180 DEG C and rapidly cooled; and 5, the cooled disc cutter is heated to 250 DEG C and then put into quartz sand to be subjected to natural cooling.
Description
Technical field
The present invention relates to the Technology for Heating Processing of cutting disc.
Background technology
The toughness of cutting disc, hardness and the wearability commonly used at present are all not ideal enough.
Summary of the invention
It is an object of the invention to provide the Technology for Heating Processing of a kind of cutting disc, it can improve the toughness of cutting disc, hardness and wearability.
For achieving the above object, the technical scheme is that the Technology for Heating Processing designing a kind of cutting disc, comprise the steps:
1) cutting disc is preheated to 600-650 DEG C by heating furnace；
2) being quenched by the cutting disc after preheating, hardening heat is 1050-1100 DEG C, puts into soak in aerial kerosene cool down for 3 hours after quenching 1 hour；
3) cutting disc after quenching being cooled down is put into and is carried out tempering in tempering furnace, and temperature is 400-420 DEG C, puts into immersion in machine oil and cool down for 3 hours after tempering；
4) cutting disc after tempering being cooled down heats to 1100-1200 DEG C with the firing rate of 400 DEG C/min in a vacuum, puts into immediately after in the liquid nitrogen of-180 DEG C and cools down rapidly；
5) cutter after cooling is heated to 250 DEG C, place into natural cooling in quartz sand.
Advantages of the present invention and having the beneficial effects that: providing the Technology for Heating Processing of a kind of cutting disc, it can improve the toughness of cutting disc, hardness and wearability.
