Matching of productive capacity among working procedures and allocating of continuous casting machines for quality steel in a converter plant

On the basis of the production run research of a BOF steelmaking workshop, the matching analysis and comprehensive research of productive capacity among BOFs, LFs and CCMs were carried out from the aspect of basic mass flow parameters. Applying OPT technology to this study, the bottleneck of coordinating operation for the previous process was the continuous casting machine (CCM), which was determined through analyzing three ways to enhance productive capacity. The optimized scheme of productive capacity matching for different working procedures was put forward, which was the strands of CCM increased from 4 to 5 in the former process of the steelmaking plant. At last, the matching mode of converters, LFs and CCMs in the medium and small size BOF process was discussed, and the matching mode of one BOF-one LF-one CCM is feasible on some condition.
