Method and plant for the manufacture of a deep-drawing steel strip or sheet

Abstract From the Canadian patent

In the manufacture of steel strip or sheet suitable for use as deep-drawing , steel for the manufacture of can bodies by deep-drawing and ironing there are , performed the steps of (i) providing a low-carbon steel in the form of a slab (ii) rolling the slab in the austenitic region to reduce its thickness to a transfer thickness, (iii) cooling the rolled slab having the transfer thickness into the ferritic region, (iv) rolling the rolled slab in the ferritic region to a finished thickness. To provide a steel having reduced tendency to "earing" in can body manufacture the transfer thickness is less , than 1.8 mm and the total thickness reduction in the ferritic region from the transfer …
