Process characteristics of mould making for slope protection
It has lower hot forging deformation resistance, good plasticity,
wide forging temperature range, low cold forging cracking and
precipitation of net carbide.
2. annealing process
Spheroidizing annealing has wide temperature range, low annealing hardness, small fluctuation range and high spheroidizing rate.
The cutting parameters are large, the tool loss is low, and the machined surface roughness is low.
4. oxidation and decarburization sensitivity
When heated at high temperature, the oxidation resistance is good,
decarburization rate is slow, insensitive to heating medium, and has
little pitting tendency.
After quenching, it has uniform and high surface hardness.
After quenching, a deeper hardened layer can be obtained and quenched with a mild quenching medium.
7. quenching deformation and cracking tend to be small in
conventional quenching, small in shape, warping, slight distortion, and
low in deformation tendency. The sensitivity of conventional quenching
is low, and it is not sensitive to quenching temperature and workpiece
The relative loss of grinding wheel is small, and the maximum
amount of grinding without burn is large. It is not sensitive to
grinding wheel quality and cooling condition, and is not easy to wear
and grinding cracks.
