Analysis and Optimization of Stamping Properties of SPCC Cold Rolled Strip
YIN Cuilan
Abstract：The analysis to the different annealing temperature under SPCC strip of metallographic showed that SPCC steel in the annealed at 600℃ has occurred recrystallization, in 680-720℃, the grain is uniform, and there are a certain number of pancake grains, higher than 720℃, grain start growing. Cold rolled plate pressure ratio respectively 73.85% and 70%, the grain is uniform, the corresponding comprehensive mechanical properties can be got the best. Through optimizing cold rolling total percent reduction rate to 70%-78% and optimal annealing process parameters, stamping property indexes such as yield strength, tensile strength, elongation at break, n value, r value and IE value were significantly increased, and the process stability improved. The unqualified ratio due to the properties was reduced by 2.68%, and the loss due to quality objection was decreased by 125 000 Yuan per year.
