SECONDARY REFINING EQUIPMENT AND SECONDARY REFINING METHOD FOR MOLTEN STEEL

摘要

In this secondary refining equipment for molten steel a first vacuum chamber and a second vacuum chamber are respectively equipped with horizontal transfer mechanisms that move the first vacuum chamber and the second vacuum chamber horizontally between a first processing position located above a first track a second processing position located above a second track a first resting position located on the side opposite the second processing position with the first track therebetween and a second resting position located on the side opposite the first processing position with the second track therebetween said movement being in a direction orthogonal to the lengthwise direction of the first track and the second track when the first vacuum chamber and the second vacuum chamber are viewed in a plane.
