PROBE FOR TAKING SLAG SAMPLES

The invention relates to a probe for taking slag samples from liquid slag during metal (especially steel) production, said probe comprising a flat cylindrical sample cavity connected to a feeding hopper by means of a channel. The cavity is defined at least on the periphery thereof by a metal ring and at least one of the upper and lower sides of the cavity is formed by a metallic cooling element. The invention is characterised in that the feeding hopper and the channel are respectively moulded into a metal segment and the channel segment lies on the metal ring which, in turn, lies on the cooling segment formed from a copper element having a thickness corresponding to a multiple of the height of the cavity. Said elements and segments can be inserted, in a reversed above-mentioned sequence, into a metallic housing open on one side, and can be removed from same, wherefor a device is provided for ejecting elements and segments located in the housing.
