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.
