Aimed at the disadvantage of the traditional annealing

such as

low efficiency

high energy consuming

polluting the environment

bad oxidation of the product surface

and so on

a new technique carrying through the annealing and soften treatment with pulse electric current on the Q235 steels was put forward in the test.The experimental device was designed and the parameter was optimized in this research.And the annealing mechanism was also explored according to the analyzing of the metallurgical structure and th...
