ABSTRACT:
A method of sampling a stream of molten material, such as slag, matte, or the like, by moving a cooled sampling arm through the stream to pick up a coating of solidified molten material as a sample, and recovering the sample by collecting pieces of the coating as it contracts and breaks apart. Apparatus for carrying out the method comprises a sampling arm, means for cooling the arm, means for moving the cooled arm through a stream of molten material, and means for recovering the broken coating sample. In preferred forms of the apparatus, a hollow sampling arm is internally cooled continuously and comes to rest over a sample recovery bin or other receiving means for recovering the broken pieces of the coating sample as it contracts and the pieces fall off by gravity.
