Question

The thickness of iron slabs after rolling is around _______

(a) 550 mm

(b) 150 mm

(c) 100 mm

(d) 250 mm

The question was posed to me in class test.

My doubt stems from Manufacture of Tinplate in division Metal Packaging Materials of Food Packaging Technology

Answer 1

The correct option is (d) 250 mm

Easy explanation: These metalloids must be substantially reduced in the steelmaking stage, and this is commonly accomplished using a basic oxygen furnace. From the furnace, the steel is cast into ingots, which are subsequently rolled into slabs about 250 mm thick or, more commonly today, continuously cast into slab form.
