Abstract
A sublance for use in performing measurements and/or taking samples in a metallurgical furnace, which has an elongate outer body (3), (11) having at its upper end a suspension structure (4), and at its lower end (12) a probe (10). Near the upper end, the body is divided by a rotational coupling (8), (9) into two parts, the lower part 11 being relatively rotatable about the longitudinal axis, so that bending distortion of the lance in use can be reversed by turning the lance through 180.degree.. To achieve a simple construction, the inner and intermediate tubes (15), (14) within the lance are not rotationally divided but extend within the rotatable outer part (11) to the lower end (12) where the inner tube (15) is rotationally coupled to the probe.
