Direct rolling process for heavy-medium plate billet continuous casting-rolling mill set

The present invention discloses a straight rolling process of heavy and medium slab continuous-casting continuous-rolling mill train. Its technological process includes the following steps: converter-LF furnace-casting machine-cutting slab into size-feeding roller table-high-pressure water descaling-vertical roll sizing-roughing-hot coiling box-flying shear cutting head and cutting tail-high pressure water descaling-finished rolling-laminar flow cooling-coiling to obtain finished product. It is characterized by adopting casting blank straight rolling process.
