Abstract
An apparatus and method including a runner system for transferring molten metal from a blast furnace to transfer cars. The runner system comprises a single main runner with primary and secondary outlets. In the preferred embodiment the secondary outlet is a nozzle positioned midway between the lower end of the runner and the blast furnace. During tapping the nozzle is opened and closed to control the flow of metal. When the nozzle is closed molten metal flows down the runner, through a primary outlet and into a bottle car. When the nozzle is open, metal flows through the nozzle into a bottle car positioned beneath the nozzle.
