Abstract
Effective controlled billet rolling on the OAO MMK 5000 mill permits the production of pipe for underground pipelines (diameter 1220 mm; wall thickness 22 mm) from steel of strength category X80. The slab temperature before rolling may be reduced to 1100°C, with corresponding adjustment in the rolling energy and with the required solubility of carbonitrides of the microcomponents, so as to ensure the required strength.
