Abstract

1. Apparatus for holding and guiding an immersion lance through which products are introduced into a steel melt by means of a carrier gas characterized by the fact that the apparatus has two arms (4, 5) flexibly interconnected by a shaft (15g) as well as two guide arms (6, 7) parallel to the arms (4, 5) a central bracket (3), an immersion lance mounting support (11) and a device (13) for raising and lowering the two arms (4, 5) with the immersion lance (2), acting on one of the guide arms (7), the two arms (4, 5) being connected, at their respective ends opposite to said shaft (15g) and via a shaft (15b) and a shaft (15j) respectively, to the bracket (3) and to the lance mounting support (11) respectively.
