Abstract: There is provided a method of continuous casting two or more long products using a single continuous twin casting strand (CCM) comprising two sub-strands. The process control of the method is automatic and comprises master/slave logic. wherein one sub-strand of the twin casting strand is a master sub-strand and remaining sub-strand(s) are slave sub-strand(s). The master strand has non-controlled metal flow and liquid metal level in the master sub-strand is regulated by adjusting casting speed. The liquid metal level in said slave strand(s) is regulated by adjusting the liquid metal pouring rate.
