During the induction heat treatment process, some process parameters such as heating, cooling, self-tempering, affecting the quality of the quenching parts, so it is necessary to comply with the relevant process regulations. Dongguan Guangyuan variable frequency sensing heating equipment found so...
In the steel pipe weld annealing, there are two types of steel pipe longitudinal welds and annealing on the weld welds, and the two methods have been described in detail. 1. A longitudinal direct weld annealing steel pipe longitudinal welds in the longitudinal direction of steel pipe is to refin...
Sensive annealing is cooled in air after the workpiece reaches an annealing temperature, so it is actually inductive normal fire, but it is used to annealing. Induction annealing is widely used in steel pipe weld annealing, recrystallization of reflections (such as high pressure tubing portions)...
1. Eliminate stress and normal tractor high pressure tubes are cold-headed expansion (20 steels), and also use induction normal fire to restore normal.
