Conclusions
-
1.
The heating time for disks of the thicknesses indicated does not limit the possibility of using automatic lines for low-distortion heat treatment in dies. To increase the throughput of the line (for heat treatment of disks 10 mm thick, for example) it is possible to use multiposition heating of the parts, multirow equipment, etc.
-
2.
To reduce distortion during heat treatment to the minimum, we recommend quenching in dies for dat parts with the following thicknesses:<-3 mm for parts made of carbon steels U7 and U8;≤10 mm for parts made of structural alloy steels of the 65G type;≤10 mm for carburized steel of the 20Kh type.
