一、“控制轧制”及其效应“控制轧制”法是控制钢材在热加工时诸工艺参数,即 (1) 加热温度; (2) 在奥氏体区变形量的分配和道次压下量; (3) 变形速度和总变形量; (4) 终轧温度; (5) 冷却速度; (6) 卷取温度。通过控制这些工艺参数,能使钢材内部组织结构达到所期望的形态,从而有效地发挥钢的内在潜力,大幅度提高钢材的性能。但根据设备、工艺和轧材的品种与形状之不同,控制的参数有主次之分。如轧制中厚板时一般强调控制变形量和终轧温度,而轧制板卷或线材时则强调控制冷却速度和卷
First, the “controlled rolling” and its effects “controlled rolling” method is to control the steel in the thermal processing of the process parameters, namely (1) heating temperature; (2) distribution of austenite deformation and pass pressure (3) Deformation speed and total deformation; (4) Finishing temperature; (5) Cooling rate; (6) Coiling temperature. By controlling these process parameters, the internal structure of the steel can be brought to the desired shape, thereby effectively exerting the inherent potential of the steel and greatly improving the properties of the steel. However, according to the equipment, technology and rolled products of different varieties and shapes, the control of the parameters of the primary and secondary points. Such as the rolling plate generally emphasizes the control of deformation and finishing temperature, while rolling the coil or wire is emphasized when the control of cooling rate and volume
