Title:
鋼帯を非連続的に製造するための方法及びプラント
Document Type and Number:
Japanese Patent JP2009520882
Kind Code:
A
Abstract:
A process for manufacturing steel strips with solution of continuity. The steps of the process include a continuous casting step for thin slabs with a high “mass flow,” a shearing step and subsequent heating in furnace, followed by a multiple stand rolling step with the average temperature of the product at the inlet of the rolling mill being higher than the surface temperature, which is equal to at least 1100° C., lower than that measured in the inner central area by about 100° C. A plant is also described for the accomplishment of such process where at the inlet of a furnace, possibly of the induction type, combined with a temperature maintaining tunnel a shear is provided for cutting into pieces a slab coming from continuous casting with the distance between the outlet of the continuous casting and the inlet into the finishing rolling mill is not greater than 100 m.
