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

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.
