FIELD: physics.
SUBSTANCE: immersion probe has a housing whose longitudinal axis is surrounded by an outer surface. Part of the outer surface of the probe is fitted with sampling elements which pass around the longitudinal axis in the peripheral direction and which have radial extension. Around the sampling elements there is a protective layer which can dissolve or burn in molten steel or slag. The sampling elements have a flat or concave surface facing away from the immersed end of the housing of the probe. The sampling elements can also have a flat or concave surface which faces away from the immersed end and which is inclined relative the longitudinal axis in the direction of the end of the housing of the probe, opposite the immersed end. The sampling elements are in form of one or more annular segments lying one behind the other in the direction of the longitudinal axis.
EFFECT: efficient collection of slag samples.
