Basic principles for determining the forging temperature range of forgings
- Feb 12, 2018 -

Forging start forging temperature and forging end temperature, that is, forging temperature and final forging temperature between the interval is called forging temperature range.

Starting from improving plasticity and reducing deformation resistance, it is hoped that as much as possible to improve the heating temperature of forging billet; but to ensure product quality, to avoid heating defects, the heating temperature is too high and not good. In order to reduce the number of fires, save energy and improve labor productivity, not only hope that the heating temperature is high, but also hope that the end of the forging temperature is lower; but in order to avoid severe work hardening and lead to forging cracks, forging temperature should not be too low. Thus, these factors are contradictory to each other, so to determine the forging temperature range must be fully considered.

The basic principles for determining forging temperature range:

1, to ensure forging billet in the forging temperature range has good ductility and lower deformation resistance.

2, to ensure good quality (referring to the internal organization and mechanical properties) forgings.

3, as far as possible to expand the forging temperature range, in order to reduce the fire, save energy and improve forging productivity.

Forging business in the above principles to consider, the idea of building the first quality, first of all to ensure that the billet heating is good, to ensure that the forging out of good plastic and good ductility, while reducing the heat to improve labor productivity and reduce heat loss .
