hardened and tempered equipment technical reform
hardened and tempred equipment technical reform
1)It is reform for the existing equipment techical according to the process testing and analysis of the heating treatment spring steel strips' surface blueing.what is more,it is increased ammonia decomposition,measuring,safety device at the begining of the entrance of quenching and temper's furnace.
2)Our factory having already transformed the technical for the existing blueing furnace.and furnace body length from 6250mm to 12900mm,changing the furnace tube with oval into rectangular,and it is add an air outlet in the centre of the furnace tube.and take measure in energy-saving structure,which can make the temperature more uniform and remain the runing speed constant when quenching and tempered
3)To be reformed for the production line,improve the productivity.and it is made sure the blueing furnace length according to the quenching speed,it is better to adopt the temperature best match the blueing time for different size.
Conclusion:according to experiment test and speed operation these days,we found the principle of the blueing and the main factor has effect on the steel strips' blueing.and make sure that the best temperature and blueing time for various size,and reforming the production line of the quenching and tempered,which not only can improve the blueing quality and rust resistance of our factory's heating treatment spring steel strip,but also can enhance our competition,reflecting our advantage of heating treatment with hardened and tempered in advance.
