Patent number: 10495551Abstract: A sampler for taking samples from a molten metal bath, particularly a molten iron includes a sample chamber assembly having a cover plate and a housing. The housing has first and second openings for an inflow conduit and a gas coupler, respectively. The first face has an analysis zone, a ventilation zone, and a distribution zone. A depth of the analysis zone is 0.5 mm to 1.5 mm. The cover plate and the housing are assembled together to form a sample cavity. The sample chamber assembly chills the molten iron received therein to a solidified white structure metal sample. An analysis surface of the sample lies in a first plane. In a flow direction of the molten iron, there are no increases in width of the sample cavity and a ratio of the length to depth of the sample cavity increases.Type: GrantFiled: December 6, 2017Date of Patent: December 3, 2019Assignee: HERAEUS ELECTRO-NITE INTERNATIONAL N.V.Inventors: Dries Beyens, Jean-Paul Verhoeven

Patent number: 10352832Abstract: A sampler for taking samples from a molten metal bath, particularly a molten steel bath, includes a sample chamber assembly having a cover plate and a housing. The housing has an immersion end provided with an inflow conduit and including a sample cavity including a distribution zone, an analysis zone, and a ventilation zone. The sample cavity is dimensioned into four contiguous segments each of which has a respective length and depth. The four contiguous segments satisfy the formula: (L1/D1)+(L2/D2)+(L3/D3)+(L4/D4)>25.Type: GrantFiled: December 11, 2017Date of Patent: July 16, 2019Assignee: HERAEUS ELECTRO-NITE INTERNATIONAL N.V.Inventors: Dries Beyens, Jean-Paul Verhoeven
