MODULAR MICRO MILL AND METHOD OF MANUFACTURING A STEEL LONG PRODUCT

摘要

A modular micro mill for manufacturing steel long product from scrap metal using an induction melting furnace is disclosed. Scrap or pre-refined metal is delivered and melted in the induction melting furnace, the melted steel then being transferred by a preheated tundish to a casting station for producing billets. From the caster the billets are transferred directly to a billet staging station and stored in queue for delivering to main conveyor leading directly to the rolling mill without being cooled to ambient. The bars produced by the rolling mill are then quenched to impart desired metallurgical properties within the finished product. A control system runs the operation of the production line of the modular micro mill, the control system specifically adapting production rates, conveyor speeds, temperatures, etc. of components upstream within the production line based on the specific requirements and/or dimensions of the finished product exiting the production line.
