    Abstract: A plain carbon steel strip is continuously cast in a twin roll caster and passes to a run out table on which it is subjected to accelerated cooling by means of cooling headers whereby it is cooled to transform the strip from austenite to ferrite at a temperature range between 850null C. and 400null C. at a cooling rate of not less than 90null C./sec, such that the strip has a yield strength of greater than 450 MPa. The strip after casting and before cooling is passed through a hot rolling mill to reduce the thickness of strip by at least 15% and up to 50%.
