Abstract
A steel-smelting lance assembly has a fixed support head having a horizontal lower face and is formed with a plurality of fluid passages opening at the face. A plurality of fluid-carrying conduits are permanently connected to the head and communicate with these passages. A lance tube is provided on its upper end with a connector piece having an upper face and formed with a plurality of passages opening at the face and alignable with the passages of the support head. A pair of bolts pivoted on the support head are engageable in notches on the connector piece so as to align the passages in the connector piece with the passages in the support head and allow the two faces of these elements to be clamped together by tightening nuts on the bolts.
