1, heat treatment is the most important, which determines the high quality of products.

2. The process method should be optimized and the equipment performance should be mastered.

3. The parameters of each section are selected correctly, and those with high efficiency and reliability are preferred.

4, heating insulation cooling, interlocking is not sloppy.

5, steel composition changes, should consider the influence of phase transformation.

6. By calculating and adjusting the parameters, the process is reliable and more practical.

7, steel categories to distinguish, reasonable options more scientific.

8. The heating temperature is very important, and the holding time should be sufficient.

9, high alloy steel to be segmented, slow heating is guaranteed.

10, overheating and underheating are unfavorable, but more consideration is needed.
