摘要： PROBLEM TO BE SOLVED: To generate a highly accurate method based on a method kind in a method for analyzing existing program information, preparing job rule information and generating the method of an object from the job rule information and object information. SOLUTION: Job rule kind judgement 101 inputs the job rule information 200 and data item information 300, judges the kind of a job rule and prepares the job rule information 210. The object information 400 sets the name and kind of the attributes of the respective objects. A method setting chart 600 sets the method kind determined from a rule kind and an attribute kind. Job rule selection 103 selects the job rule for which a corresponding object is present, method kind specification 104 specifies the method kind by referring to the method setting chart 600 and the method is generated through processings from method setting 105 and thereafter and is stored in method information 500.

摘要： PURPOSE:To avoid the scattering of signal and noise amplitude at a defect part and raise the sensitivity by providing a demagnetizer upstream side of a leakage-flux flaw detector and quantify the size of the defect. CONSTITUTION:A demagnetizer 14 is placed upstream side of a leakage-flux flaw detector 6. With this demagnetizer 14, a strip 1 processed on line is continuously demagnetized. As for the demagnetizer 14, such a one is suitable that generates alternating magnetic field and obtains attenuation effect by passing there the strip 1. Since the strip before the magnetic flaw detection is demagnetized using the demagnetizer 14, scattering in the magnetic characteristics of the strips with different components in steel can be avoided. Resultingly, the output signal and noise amplitude of defects detected with the leaked magnetic flux flaw detector 6 can be equalized, and so a certain discrimination level can be determined and also the defect size can be quantified from the output signal of the defect.

摘要： PURPOSE:To prevent the formation of a wood-grain pattern by providing a looper capable of adjusting the length of a steel strip in a reflowing device. CONSTITUTION:A steel strip 2 is sent into a plating tank 1 by a deflector roll 3, and the strip 2 is electroplated with tin by a conductor roll 4. The strip 2 is passed through a muffle furnace in the form of loop, and a carriage 18 is vertically moved to change the distance of reflowing. Consequently, since the length between the conductor rolls 12 and 14, namely the electric resistance, is changed, the temp. rise per unit time is controlled, and the coating weight to form a wood-grain pattern is controlled without lowering the line speed.

摘要： PURPOSE:To replate a tin free steel sheet to recover defective one by applying temper-rolling again to an off-grade tin free steel sheet of defective appearance to dissolve appearance defect and then chrome-plating it. CONSTITUTION:Temper-rolling is executed to the tin free steel sheet of off-grade with appearance defect such as scratch or irregular color tone. The steel sheet appearance defect of which is dissolved by this way is chrome-plating. In this case, the steel sheet is more preferably chrome-plated after the destroyed chromium layer of the upper layer is adequately removed in a pretreatment of the plating process than in a state that the steel sheet is chrome-plated while appearance defect of the steel sheet is destroyed and removed by temper-rolling again as it is. As a result, the defective is saved and the good appearance tin free steel sheet excellent in corrosion resistance is obtained.

摘要： PURPOSE:To prevent the generation of wood grain patterns while retaining the island-shaped distribution of tin by accelerating the formation of an oxide film after melting of tin in an atmosphere where an oxygen concn. is high. CONSTITUTION:The steel plate is enclosed by sealing rolls 3 and a sealing box 4 at the time of executing a reflow treatment at a high speed. Pure gaseous oxygen is charged therein and the oxygen concn. is controlled to >=30%. The temp. of the steel plate of this time is set at about the m. p. of the tin and the tin is distributed uniformly to the island shape on the surface of the steel plate by the balance of the surface tension of the molten tin and the interfacial tension of the base iron.
