Abstract: 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.

Abstract: A cup assembly for holding a sample to be analyzed spectrochemically, includes a tubular longitudinal member which is disposed symmetrical about a central axis. The tubular member extends longitudinally between a first end and a second end. An indented peripheral flange is defined at the second end. The indented flange has an inverted L shaped cross-section. An annular collar extends longitudinally between a first end and a second end. An internal peripheral flange is defined at the first end. The internal flange has an inverted L shaped cross-section complementing the indented flange of the tubular member. When a substantially thin film is interposed between the second end of the tubular member and the first end of the annular collar, the film is retained between the sample cell body and the collar between the indented flange and the internal flange. The cup may have a funnel shaped sample retaining chamber.

Abstract: A device is provided for sampling metal melts, in particular molten iron and molten cast iron, with a sample chamber having an inlet opening and tellurium arranged in the sample chamber. The sample chamber contains 0.01 to 0.05 g/cm3 tellurium based on the volume of the sample chamber and the tellurium is in powder form having an average particle size of at most 150 ?m. Additionally or alternatively, the tellurium is in powder form having an average particle size of at least 150 ?m and a specific surface area of 0.03 to 0.1 m2/g.

Abstract: Optical qualities of a production lot of base material used in the fabrication of semi-finished lenses may be accurately determined by employing chipper plate samples produced from the base material in accordance with aspects of the present invention. In various implementations of the present invention, the chipper plates samples may be fabricated by subjecting base material to an extended cycle time and temperature profile using a mold having cavities of different thicknesses. The resulting chipper plates provide an improved indication of the color of semi-finished lenses molded from the production lot as well as an improved indication of resin stabilizer defects that may be utilized during a pelletizing process to control and enhance the quality of a production lot. Furthermore, the chipper plates may be provided by suppliers as samples of a production lot to enable customers to base purchasing decisions on a reliable and accurate measure of optical properties.

Abstract: A process and a device for easily and rapidly producing a metal sample for analysis for determining the content of impurities in a molten metal with high accuracy. More particularly, according to the metal sample production process, a metal sample for high accuracy analysis is produced by solidifying a collected molten metal without segregating impurities contained in a molten metal, by rapidly cooling a collected molten metal using a metal sample production device having a thin-walled mold having a thin sample collection space for collecting a molten metal, and an opening/closing operation part with which the mold can be freely opened/closed.

Abstract: A method and apparatus for molding a reproducible uniform concrete test cylinder. Concrete is poured into a concrete test cylinder mold. A cap having at least one excretion hole is placed on the top portion of the concrete test cylinder mold. The cap is pressed against the top portion of the concrete test cylinder mold thereby excreting excess concrete through the excretion hole in the cap. After the cap is separated from the poured concrete, the poured concrete is allowed to cure within the concrete test cylinder mold for a predetermined time. Then, the cured concrete is removed from the concrete test cylinder mold thereby producing a uniform and reproducible concrete test cylinder.
