Abstract
A method of refining steel utilizing induction melting furnaces sized for use in micro mills consists of charging a medium frequency induction melting furnace having a maximum production rate of about 50 tons per hour with pre-refined steel, and melting steel in the furnace. The melted steel is transferred to a refining vessel, the refining vessel has a high free board, induction heating and stirring capacity and apparatus for supplying blasts of gas. The refined steel is then transferred to a tundish for a continuous casting operation.
