The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, our company sang songs to the mark the 70th victory anniversary. In September, we organized all employees to sing "My Country and I" and made a film.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S690QL1 steel plate are higher than that of annealed S690QL1 steel plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of S690QL1 steel plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.
