    摘要: An apparatus and method for imaging the interior of a hot dip melt pot snout of a hot dip steel coating apparatus through the snout thereof. The system provided for high visual contrast and high resolution imaging, without the need for external illumination. The inventive apparatus and method image the interior of the hot dip melt pot snout at infrared wavelengths, and preferably in a wavelength range of 0.7 to 3 microns. The inventive apparatus and method provide valuable information about the condition of the hot dip melt pot snout and steel coating process which may be used to improve the quality of the produced coated steel.

    摘要: The invention relates to a method for the production of a martensitic steel sheet having a yield point greater than 1300 MPa. The method comprises the following steps consisting in: supplying a semi-finished steel product having a composition containing, expressed as weight percent, 0.15% ≤ C ≤ 0.40%, 1.5%≤ Mn ≤ 3%, 0.005% ≤ Si ≤ 2%, 0.005%≤ Al ≤ 0.1%, S ≤ 0.05%, P≤ 0.1%, 0.025%≤ Nb ≤0.1% and, optionally, 0.01% ≤ Ti ≤ 0.1%, 0% ≤ Cr ≤ 4%, 0% ≤ Mo ≤ 2%, 0.0005% ≤ B ≤ 0.005%, 0.0005% ≤ Ca ≤ 0.005%, the remainder of the composition being formed by iron and the inevitable impurities resulting from production; heating the semi-finished product to a temperature T
    1 between 1050°C and 1250°C and, subsequently, subjecting the heated semi-finished product to rough rolling at a temperature T
    2 between 1050 and 1150°C, with a cumulative reduction rate ε
    a greater than 100%, such as to obtain a sheet having an austenitic structure that is not totally recrystallised, with an average grain size of less than 40 micrometres and preferably less than 5 micrometres; and cooling the sheet, such as to prevent the transformation of the austenite, at a rate V
    R1 greater than 2°C/s to a temperature T
    3 between 970°C and Ar3+30°C, and, subsequently, subjecting the cooled sheet to final hot rolling at temperature T
    3 , with a cumulative reduction rate ε
    b greater than 50%, such as to obtain a sheet that is then cooled at a rate V
    R2 above the critical cooling rate.

    摘要: The invention mainly relates to metal siding (5), which is to be attached to a supporting structure via an array of profile members, including: at least one ribbed metal sheet (6) consisting of alternating ledges (9) and grooves (10), at least two clips (7) inserted into and attached to one of the grooves (10), the clips (7) consisting of a base (13) and two symmetrical arms (15) arranged so as to form at least one narrowed area (16) and at least one widened area (17), at least one cover (8) fitted onto or into the clip (7), the cover (8) consisting of a profile member made of a cap (18) and two symmetrical arms arranged so as to form at least one narrowed area (20) and at least one widened area (21), the shapes and sizes of which are substantially equivalent to those of the narrowed (16) and widened (17) areas of the clip (7), respectively, at least one flat element (22) wedged into at least one of the widened areas (17, 21) and preventing the movement of the cover (8) relative to the clip (7). The invention also relates to the related manufacturing method and manufacturing kit.
