Abstract
Methods and apparatuses for continuously producing steel intermediate products are disclosed. Liquid steel is cast into plural moulds to continuously produce plural bloom strands using continuous casting apparatus. Subsequently, one or more of the bloom strands is fed in-line to respective rolling mills configured to hot roll the input continuously cast bloom strands to produce rolled billets.
Claims26
A method of continuously producing steel intermediate products, comprising:
- casting liquid steel into plural moulds to continuously produce plural bloom strands;
- and
- feeding one or more of the bloom strands in-line to respective rolling mills configured to be selectively engageable to hot roll the input continuously cast bloom strands to produce rolled billets,
- wherein the rolling mills comprise two or more cantilever rolling mill stands in which bearing supports for the rollers of each stand support the rollers at only one end, and wherein the angle of the axes of the rollers of the first cantilever rolling mill stand for a given bloom is set at 45 degrees to the top surface of the bloom and wherein the angle of the axes of the subsequent rolling mill stands is set at 90 degrees to each other.

Apparatus for continuously producing steel intermediate products, comprising:
- continuous casting apparatus arranged to, in use, continuously produce plural bloom strands;
- and
- one or more in-line rolling mills each arranged to be selectively engageable to receive and hot roll, in use, one of the continuously cast bloom strands to produce rolled billets,
- wherein the rolling mills comprise two or more cantilever rolling mill stands in which bearing supports for the rollers of each stand support the rollers at only one end, and wherein the angle of the axes of the rollers of the first cantilever rolling mill stand for a given bloom is set at 45 degrees to the top surface of the bloom and wherein the angle of the axes of the subsequent rolling mill stands is set at 90 degrees to each other.
