| Abstract: | By analyzing the causes of disqualified elongation rate of controlled rolling Q420C steel plate, it is found out that mixed grain and hard phase structures the major causes of the elongation rate disqualification of steel plate. Aiming at the above causes, process improvement measues have been taken for the controlled rolling Q420C steel plate of thickness 440 ram. The problem of disqulified elongation rate of controlled rolling Q420C steel plate is resolved at last. |
