With the continuous development of industrial technology,the research and development of new materials has higher requirements.The microstructure changes of stainless steel and carbon steel hot rolled steel plates during heating and cooling were observed in situ with the microscope imaging system of high temperature confocal microscope.The starting and ending points of phase transformation at each stage,the whole process of austenite grain change,and the accumulation and growth of inclusions in molten steel were determined by experimental observation.
