The study aims to develop a new,resource-saving cold-rolled steel production process for floor,and to obtain the best stamping performance of this material.In this experiment,using X2-4-10 box type resistance furnace equipment,combined with hardness curve method,L9(3 factors and 3 levels)orthogonal test,and a new orthogonal data analysis method,the influence of process parameters such as heating temperature,holding time and cooling mode on the material performance are explored.Finally,the optimum batch annealing process suitable for the full specification of cold rolled floor steel under the chemical composition system was obtained:710℃heating temperature+8 h holding time+slow cooling methods,which contributes to providing a certain theoretical basis for the industrial trial production.
