Abstract
A slag control shape is releasably mounted on a cover for a molten metal vessel. An actuator is connected to a slag control shape release member to retract the release member from a first position engaged with the slag control shape to a second position separated from the slag control shape allowing the slag control shape to freely drop into the molten metal receptacle. The actuating end of the actuator is located at an easily accessible operator position for remote actuation of the release member. In one embodiment, the actuator is a flexible cable attached at one end to the release member mounted on the cover and having a second end located remote from the cover at an easily accessible operator position. In another embodiment, one end of a cable wound in a plurality of turns about a rotatable shaft mounted in a reel is attached to the slag control shape. A spring biasingly engages the shaft to control the rate of rotation of the shaft and thereby the rate of payout of the cable and the rate of descent of the slag control shape into the molten metal vessel. A detector counts the revolutions of the shaft as the cable is paid out to measure the distance the slag control shape has descended into the vessel.
