摘要： An ultralow-iron-loss grain oriented silicon steel plate remarkably improved in the undercoating adhesion onto the matrix surface, remarkably reduced in iron loss as compared with the prior art materials and also excellent in magnetic strain characteristics can be produced at a low cost with a high producibility by forming, at the boundary between the surface of a matrix and a tension isolating coating of a silicon steel plate, a boundary layer such as a layer of a nitride/oxide of at least one element of Fe, Si, Al and B or an ultrathin undercoating comprising a nitride/oxide of at least one element of Fe, Si, Al and B finely dispersed in the coating component same as the tension isolating coating, optionally after dissolving the matrix surface by dipping the steel plate in an aqueous solution of chlorides mainly comprising SiCl4 or after conducting flattening or pickling in an aqueous solution of SiCl4.

摘要： A continuous heat treating furnace comprising a quenching zone (11) constituting one of a plurality of furnace zones excluding the first and the last zones and adapted to quench materials by blowing an atmospheric gas and, as atmospheric gas sealing means, a roll seal room (3) disposed at an entrance and partitioned by first and second roll seal devices (4A, 4B) arranged in that order from the upstream side and a third roll seal device (4C) disposed at an exit, wherein the entrance of the first roll seal device is connected to the exit of the third roll seal device and/or roll seal rooms are connected to the upstream-most portion (6) of the quenching zone, an in-furnace hydrogen concentration being controlled to not lower than 10 % in the quenching zone and to not higher than 10 % in zones on the entry side of the quenching zone. The above design can provide a continuous heat treating furnace that can prevent by a simple means mixing of an atmospheric gas in the quenching zone using a gas jet cooling system with an atmospheric gas in zones adjacent to the quenching zone (heating zones and cooling zones), and an in-furnace atmospheric gas control method that can prevent nitriding.

摘要： A low-carbon, low-phosphorus steel material which consists of 0.001 to 0.025 wt.% carbon, up to 0.60 wt.% silicon, 0.10 to 3.00 wt.% manganese, 0.005 to 0.030 wt.% phosphorus, up to 0.01 wt.% sulfur, up to 0.10 wt.% aluminum, 0.1 to 1.5 wt.% copper, 0.1 to 6.0 wt.% nickel, 0.0001 to 0.0050 wt.% boron, and iron and unavoidable impurities as the remainder. The steel material forms a stable amorphous rust on its surface in an early stage to thereby combine excellent weatherability, which is required for use in a salty atmosphere as in coastal regions, with weldability and toughness.

摘要： A method of manufacturing metal foil capable of a high-efficient rolling without sacrifice in a metal foil shape; specifically, a method of manufacturing metal foil not larger than 0.2 mm in thickness by cold rolling in a plurality of passes, wherein rolling is effected by using a soft work roll during rolling ranging from a first pass to a pass preceding a kiss rolling occurrence, rolling reduction of higher than 30 % is accomplished by using a hard work roll in a pass where kiss rolling occurs and rolling reduction of not higher than 20 % is accomplished by using a soft work roll in a final pass or in a pass preceding the final pass and the final pass. When a hard work roll is to be used, a decision for kiss rolling is made anew and a target load in the relative pass is adjusted accordingly.

摘要： In order to display the results of detection of a flaw, such as a crack, in or just under the surface of an object, a defect signal at a level between zero and a threshold value is displayed in acolor belonging to a color area in the color space, and a defect signal at a level above the threshold value is displayed in a color belonging to a color area different from that of the former signal. Further according to the level of the defect signal, the color in the color area or the darkness is changed. As a result, even a very weak defect signal can be displayed without exception, preventing any small defect from being overlooked.
