- a casting section to cast steel blooms;
- a rolling section including a plurality of in-line rolling stations to roll said blooms into rails at least about 500 feet long and free of any weld seams;
- a controlled cooling and final cooling section to cool the rolled rails; and
- a rail transfer bed section to transfer the rolled rails laterally.
- 2. The system of claim 1 wherein said rails are about 1440 feet in length.
- 3. The system of claim 1 wherein said casting section is comprised of a hot metal transfer area, a hot metal degasser and reheating area, at least one caster, a bloom transfer bed, and a bloom holding furnace.
- 4. The system of claim 1 wherein said rolling section is comprised of a crop-shear area, an induction heat area, a descaler, and a continuous rolling mill.
- 5. The system of claim 1 wherein said rolling section and controlled cooling section are in-line with each other.
- 6. The system of claim 1 wherein said rolling section, controlled cooling section and casting section are in-line with one another.
- 7. The system of claim 1 further comprising a post-formation section comprised of inspection, defect painting, end sawing and imperfection-removing means.
- 8. The system of claim 7 wherein said imperfection-removing means are comprised of means for sawing the rail and welding means for welding the rail back together.
- 9. A system for manufacturing railroad rails comprised of:
- a casting section to cast steel blooms, comprised of a hot metal transfer area, a hot metal degassing and reheating area, at least one caster, a bloom transfer bed, and a bloom holding furnace;
- a rolling section to roll said blooms into rails at least about 500 feet long and free of any weld seams, comprised of a crop/shear area, an induction heat area, a descaler, and a rolling mill including a plurality of in-line rolling stations;
- a controlled cooling and final cooling section to cool the rolled rails; and
- a rail transfer bed section to transfer the rolled rails laterally.
- 10. The system of claim 9 wherein said casting section contains a plurality of casters.
- 11. The system of claim 9 further comprising a post-formation section comprised of inspection, defect painting, end sawing and imperfection removing means.
