    摘要: 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: (L 1 /D 1 ) + (L 2 /D 2 ) + (L 3 /D 3 ) + (L 4 /D 4 ) > 25.

    摘要: Sample chamber (3) comprising a cover plate (32) and a housing (30) forming a heat sink, said housing (30) including an immersion end (16) having a first opening (20) for a molten-metal inflow conduit (7) and an opposing end (18), and a first face (40) extending between said immersion end (16) and said opposing end (18), said first face (40) having a depression extending from proximate the immersion end (16) towards the opposing end (18), said depression being in direct flow-communication with the first opening (20) to receive the molten metal from the inflow conduit (7).
    The cover plate (32) and the housing (30) are assembled together along a first plane (AF) to form a sample cavity including the depression such that an analysis surface of the solidified-metal sample (S) formed within the sample cavity lies in the first plane (AF). The sample cavity and the first opening (20) are aligned along a common longitudinal-axis (X) and the first opening (20) is spaced apart from the first plane (AF).
    The ratio between the thermal diffusivity of the solidified-metal (S) and the thermal diffusivity of the material forming the housing (30) is between 0.1 and 0.5, the housing (30) is configured to be inseparable from the solidified-metal sample (S) and at least a portion of the housing (30) is directly adjacent to the solidified-metal sample (S) and lies in the first plane (AF).

    摘要: 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 first and second openings for an inflow conduit and a gas coupler, respectively. The first face of the housing includes a distribution zone, an analysis zone and a ventilation zone. A depth of the analysis zone is greater than 1.5 mm and less than 3 mm. The cover plate and the housing assemble together to form a sample cavity. An analysis surface of a solidified steel sample formed within the sample cavity lies in a first plane. In a flow direction of the molten steel, there are no increases in a width dimension of the sample cavity and a ratio of the length to depth of the sample cavity increases.
