Abstract

A device for transporting molten metal in the pouring bay of a blast furnace and a process for operating this device. At least one main runner with skimmer, which main runner is installed after the tapping door of the blast furnace, is provided as well as runoff gutters arranged downstream with a transfer station into the molten metal transfer cars. A pipe section with connecting branches, which is followed by a second pipe section with a slide, is flanged to the runout in a gas-tight manner. This second pipe section is also connected in a gas-tight manner to the intake opening of the main runner. A T-shaped pipe section, which allows the pig iron to flow into one of the pig iron transfer cars, is arranged at the end of the pipe sections. To keep clear the open cross section of the wear lining of the pipe section, inert gas is blown in, which also keeps the ceramic plate of the sliding shutter clear.
