Abstract
In an arrangement for capturing and conducting away flue gases forming during charging of, and pouring off from, metallurgical vessels in a steel-making plant, the material to be charged and poured off is brought into and out of the operating position by a container displaceable by means of a crane. The crane trolley is designed to form a displaceable unit with a hood having a draft opening. The hood, in the operating position, covers the container and the mouth of the metallurgical vessel, and the draft opening borders on the discharge opening of a chimney so as to form a flow connection therewith.
