Patent No .: CN201110005359.4 Patentee: General Research Institute of Iron and Steel A method for producing high strength plastic automobile steel plate for continuous annealing process belongs to the technical field of automotive steel. By increasing the deformation energy of cold-rolled steel sheet and obtaining the non-equilibrium structure, the time required for reverse transformation of austenite is greatly shortened, and the condition of obtaining good strong plasticization within 1 ~ 10min annealing and holding time is satisfied, Continuous annealing of automotive steel cold-rolled sheet and continuous galvanizing production equipment process conditions. In addition, the use of group
