Patent number: 10151669Abstract: A sampler has a sample chamber for a sample forming from a molten material, at least one lower cooling body, at least one upper cooling body, at least one inner cooling body, and at least one filling part. The sample chamber is surrounded jointly at least by the lower cooling body and the inner cooling body, such that at least the sample chamber can be cooled by at least the lower and inner cooling bodies. The filling part merges into the sample chamber by a filling opening. Between a region of the outer surface of the inner cooling body and a region of the outer surface of the upper cooling body opposite the outer surface of the inner cooling body, the sampler has at least one gap for conducting at least one gas. The volume of the respective cooling bodies is larger than the volume of the gap.Type: GrantFiled: September 7, 2016Date of Patent: December 11, 2018Assignee: Heraeus Electro-Nite International N.V.Inventors: Guido Cappa, Gerrit Broekmans

Patent number: 9909810Abstract: An immersion device is provided for molten metal, as well as a method for making steel. The immersion device allows a trouble free operation. The immersion device includes a measuring head, a carrier for the measuring head, and a lance detachably connected to the carrier, preferably by a detachable tubular connecting element. A gas path runs from the lance to the detachable tubular connecting element. A gas tight connection is provided between a connecting surface of the lance and the detachable tubular connecting element. The tubular connecting element has wipers in the form of fins, which wipe the connecting surface of the lance during attaching and/or detaching the tubular connecting element and the lance.Type: GrantFiled: June 9, 2016Date of Patent: March 6, 2018Assignee: Heraeus Electro-Nite International N.V.Inventors: Gerrit Broekmans, Jan Cuypers

Patent number: 9128013Abstract: A sampler is provided for taking samples from melts having a melting point higher than 600° C., in particular for metal or cryolite melts. The sampler includes a carrier tube having an immersion end and having a sample chamber assembly arranged on the immersion end of the carrier tube. The assembly has an inlet opening and a sample cavity for the melt and is arranged at least partly inside the carrier tube. The sample chamber assembly has on a part of its outer surface a coupling device, arranged inside the carrier tube, for coupling a carrier lance. A method is also provided for taking samples using such a sampler.Type: GrantFiled: May 4, 2012Date of Patent: September 8, 2015Assignee: Heraeus Electro-Nite International N.V.Inventors: Lihuan Song, Gerrit Broekmans, Guido Jacobus Neyens, Dries Beyens
