控制轧制(TMCP)技术是取代离线热处理生产高性能钢材的一种生产技术,它的核心包括:(1)控制轧制温度和轧后冷却速度、冷却的开始温度和终止温度;(2)轧制变形量的控制;(3)钢材的成分设计和调整。由于不通过热处理炉离线处理即可生产高性能钢材,既为开发新品种增加了途径,又减少热处理设备投资,大幅度减少热处理能耗,且可节约合金资源,是具有高度实用价值的新技术。 Controlled rolling (TMCP) is a production technology that takes the place of off-line heat treatment to produce high-performance steel. Its core includes: (1) controlling the rolling temperature and cooling rate after rolling, the starting and ending temperature of cooling; (2) Rolling deformation control; (3) steel composition design and adjustment. As the high-performance steel can be produced without going through the heat treatment furnace off-line, it not only increases the ways for developing new varieties, but also reduces the investment in heat treatment equipment, drastically reduces the heat treatment energy consumption, and can save alloying resources. It is a new technology with high practical value .
