Abstract (en)
[origin: WO2014019673A1] The invention relates to a method for producing steel strip of carbon steel using a thin slab caster such as a DSP or DSC for continuously casting the carbon steel or a conventional slab caster with a hot connect to a hot rolling installation, comprising the following steps: providing a molten steel containing the following elements (in weight %): 0.06 - 0.17 C, max 3.0 Mn, 0.1 - 2.0 Al(zo), max 0.01 Ca and optionally one or more of the following elements: max 1.0 Cr, max 2.0 Si, max 1.0 Mo, max 0.1 P, max 1.0 Cu, max 2.5 Ni, max 0.2 V, max 0.2 Ti, max 0.1 Nb, max 0.01 B the remainder being Fe and unavoidable impurities; providing the molten steel to the mould of a thin slab caster or conventional slab caster with hot connect; casting the steel into a strand; cutting the strand into slabs; rolling the slabs into strips after the slabs have undergone a temperature equalizing or reheating step. The invention also relates to hot rolled and cold rolled and annealed steel strip thus produced.
