    摘要： The invention provides an anti-skulling material for use in the outlet nozzle of a metallurgical vessel, e.g. a tundish.
    By providing a particulate, sinterable or partially-sinterable filler material in granulated form, the granules containing the desired proportion of the particulate constituents, the invention enables greater consistency and uniformity of sintered crust to be formed in the nozzle area during contact with the molten metal in the vessel.

    摘要： A method for producing a metal ingot by using an electron-beam melting furnace including an electron gun capable of controlling a radiation position of an electron beam, and a hearth that accumulates a molten metal of a metal raw material, in which, in a downstream region between an upstream region in which the metal raw material is supplied onto the surface of the molten metal and a first side wall, an irradiation line is disposed so as to block a lip portion and so that two end portions are positioned in the vicinity of the side wall of the hearth. A first electron beam is radiated onto the surface of the molten metal along the irradiation line, and the first electron beam is radiated along the irradiation line. By this means, the surface temperature (T2) of the molten metal along the irradiation line is made higher than the average surface temperature (T0) of the entire surface of the molten metal in the hearth, and a molten metal flow from the irradiation line toward upstream that is a direction toward the opposite side to the first side wall is formed in an outer layer of the molten metal.

    摘要： [Problem]
    To provide a method for producing a metal ingot, which makes it possible to inhibit impurities contained in molten metal in a hearth from being mixed into the ingot.
    [Solution]
    A method for producing a metal ingot by using an electron-beam melting furnace having an electron gun and a hearth that accumulates a molten metal of a metal raw material, wherein the metal raw material is supplied to the position on a supply line disposed along a second side wall of the hearth that accumulates the molten metal of the metal raw material. A first electron beam is radiated along a first irradiation line that is disposed along the supply line and is closer to a central part of the hearth relative to the supply line on the surface of the molten metal. By this means, a surface temperature (T2) of the molten metal at the first irradiation line is made higher than an average surface temperature (T0) of the entire surface of the molten metal in the hearth, and in an outer layer of the molten metal, a first molten metal flow is formed from the first irradiation line toward the supply line.

    摘要： A slag volume evaluation method for a molten metal surface includes calculating an approximation curve indicating a correspondence between a thickness of slag and a density parameter in advance by measuring thicknesses of a plurality of pieces of the slag which float on a surface of a molten metal in a container and differ from each other in thickness, and calculating a value of the density parameter which is correlated to a density in a pixel region corresponding to the plurality of pieces of the slag in a captured image of a molten metal surface in the container; and calculating a volume of the slag by calculating and integrating the thickness of the slag for each of pixels constituting the captured image obtained by capturing an image of the molten metal surface which is an evaluation target, according to a value of the density parameter of each of the pixels and the approximation curve.

    摘要： A method for cleaning a surface of a twin-roller continuous thin strip casting roller, each casting roller of the twin-roller continuous thin strip casting machine using two brush rollers arranged at the top and bottom for cleaning the surface thereof, wherein a rotational direction of at least one brush roller is the same as the casting roller, a linear speed of the casting roller is constant and greater than a rotational speed of the casting roller, and a roller surface cleaning device controls a distance or a pressure between the brush rollers and the casting roller by means of a position control device fixed on a casting roller bearing seat, and controls the flattening amount to be within 1-10 times of the average pit depth of the casting roller face after brushed, so as to ensure cleaning efficiency of the roller surface. During the twin-roller thin strip continuous casting process, the present invention can improve cleaning efficiency of the continuous thin strip casting roller, make the coefficient of thermal conductivity of the roller surface to be uniform and increase cast strip quality.
