控制轧制可以看作是对低合会钢在控制最佳加热制度、达到终轧温度前的最佳变形制度和轧后控制最佳冷却制度相配合条件下的高温形变热处理。这种轧制方法作为微合金化钢种的先进生产工艺已在各工业发达国家如日本、美国、英国、西德、意大利等得到广泛应用。采用这种先 Controlled rolling can be seen as the low temperature steel in the control of the optimal heating system, to achieve the final rolling temperature before the best deformation system and rolling control the best cooling system with high temperature deformation heat treatment. This rolling method as an advanced production technology of microalloyed steel has been widely used in various industrialized countries such as Japan, the United States, Britain, West Germany and Italy.
