Patent number: 10359343Abstract: An immersion device for collecting a slag sample and measuring a molten metal parameter is provided. The immersion device includes an inflow conduit for directing the molten slag to a slag sample chamber and a measuring element for measuring the parameter of the molten metal. The inflow conduit and the measuring element are arranged in the top area of an immersion end of the immersion device and/or are facing towards an immersion direction. During immersion in the immersion direction into the molten slag and then the molten metal, the molten slag enters an external portion of the inflow conduit and is directed through an inner portion of the inflow conduit to the slag sample chamber. Reliable slag collection and molten metal measurement also in a converter can thereby be achieved. A method of collecting a slag sample and measuring a molten metal parameter is also provided.Type: GrantFiled: September 12, 2017Date of Patent: July 23, 2019Assignee: Heraeus Electro-Nite International N.V.Inventors: Dries Beyens, Paul A.
