Plain carbon strip Q235 grain growth in reheating progress

摘要：

　　Before hot rolling the ingot of plain carbon steel Q235 should be heated to austenite temperature to decrease distortion resistance.The grain size will affect the following hot rolling process.In this paper,the behaviour of Q235 grain growth in reheat furnace was studied with the method of physical simulation.To achieve the equation of grain growth in heating progress,the samples was carried out in different peak temperature and holding time at the Gleeble1500.With the kinetics equation grain size can be calculated and the results provide a basis for the setting of progress parameter during reheating of ingot.
