Abstract

A secondary cold rolled shadow mask steel strip and manufacturing method thereof comprising following processes: converter steelmaking continuous casting hot rolling pickled cold rolling continuous annealing secondary cold rolling and finishing and oil removal. Mass percentages of various main elements of the obtained shadow mask steel strip are: C=0.001% Mn 0.10 0.40% Al:0.02 0.06% Si=0.025% P=0.015% S=0.01% O=0.004%. Allowance is Fe and inevitable foreign substance. Through composition design on various elements in one aspect a weight percentage of carbon is controlled within a low content range and in the other aspect a decarburizing annealing process is omitted and a temperature of the continuous annealing is decreased shortening a production cycle and reducing production costs; through optimization of a secondary cold rolling process parameter and processing method degreasing and leveling processes are not needed and at the same time steel materials with excellent material performance and high surface quality are obtained.
