微碳钢热轧温度参数的实验室研究

STUDY OF HOT ROLLING TEMPERATURE PARAMETERS FOR MICRO-CARBON STEEL IN LABORATORY

针对微碳钢的特点 ,在实验室进行了模拟试验 ,在“三高一低”的原则下 ,研究了微碳钢加热温度对AlN溶解的影响 ,终轧温度及冷却速度对热轧晶粒度的影响 ,卷取温度对AlN和渗碳体析出的影响。提出了生产微碳钢的热轧温度参数 。

According to the characteristics of micro-carbon steel,simulative test was taken in laboratory under the principle of 'high heating temperature,high beginning rolling temperature,high final rolling temperature and low rolling temperature'.The effects of heating temperature on the AlN solubility,final rolling temperature on the grain size,coiling temperature on the AlN and cementite carbide precipitation,cooling rate on the grain size were conducted.The hot rolling temperature parameters of micro-carbon steel in laboratory were put forward.
