The invention discloses a high-magnetic-induction oriented silicon steel six-roller five-rack cold continuous rolling and cold rolling process, which is characterized in that a normalized raw material coil is subjected to a first rolling process on a pickling rolling mill combined unit, the raw material does not need to be preheated by steam before on-line uncoiling, electromagnetic induction heating is not adopted before the raw material enters a rolling mill, then the raw material is subjected to two-pass rolling on a single rack, and the final rolling thickness is 0.257 mm. According to the six-roller five-rack cold continuous rolling and cold rolling process for the high-magnetic-induction oriented silicon steel, the six-roller five-rack cold continuous rolling process is simple and reasonable, after a pickling rolling mill combined unit is adopted for carrying out first-rolling-process cold rolling on a high-magnetic-induction oriented silicon steel normalized pickling coil, two-pass rolling is carried o
