一、选题理由 9Cr_2系轧辊是齐钢产量大、效益高的锻件产品。锻后热处理退火工艺分两类:第一类是采用710℃等温球化退火工艺。该工艺特点是球化组织合格率高,但热处理周期长,能源消耗量大,生产成本也高;第二类是不完全退火。该工艺特点是球化组织合格率低,但热处理周期短,能源消耗量少,生产成本也低。鉴于当前能源紧缺的情况,需要寻找一种既能节约能源、降低生产成本、加快生产周期,又能保证

First, the reasons for the topic 9Cr_2 Department of Roller is Qi steel production, high efficiency forgings products. After forging heat treatment annealing process is divided into two categories: The first is the use of 710 ℃ isothermal ball annealing process. The process is characterized by high pass rate of ball organization, but the heat treatment cycle is long, the energy consumption is large, the production cost is high; The second is incomplete annealing. The process is characterized by low pass rate of ball organization, but the heat treatment cycle is short, less energy consumption, low production costs. In view of the current energy shortage, the need to find a way to save energy, reduce production costs, speed up the production cycle, but also to ensure
