摘要： PURPOSE:To enable long time casting of metal strip, to prevent deviation of the strip thickness and to improve the surface characteristic by arranging an internal cooling chamber in a side plate and arranging copper alloy pate on surface forming casting space. CONSTITUTION:The side plate 6 providing water cooling pipe 21 is abutted on end faces of rolls 3, 3a, and this side plate 6 is cooled by the internal water cooling 21 and vibrated by fitting on an agitator 32. Further, as material for the side plate 6, at first prevention from growth of solidified shell and wear resistance against sliding with the roll at the view point of prevention from penetration of molten metal must be considered. From these points, the copper alloy plate is arranged at the surface forming casting space. By the apparatus using this side plate 6, the growth of the solidified shell developed on the surface of the side plate 6 is prevented. Therefore, any trouble caused by falling out the shell grown in the pouring basin part at kissing part of the twin rolls, biting it into the roll and occurring abnormal rolling reduction, the trouble of casting interruption can be eliminated.

摘要： PURPOSE:To uniformize thin hoop width by prearranging a rolling reduction force standards at driving side and an operating side for free cooling rolls and correcting each the reduction force based on changing size of the roll gap and changing load of total reduction force. CONSTITUTION:Corresponding to a driving side chock 8A and an operating side chock 8B for the free cooling rolls 2, oil pressure sensors 22A, 22B are arranged respectively and also gap sensors 14A, 14B, which detect roll gaps l1, l2 corresponding to both sides respectively, are arranged. A standard rolling reduction force settler 17 prearranged standard reduction forces P01, P02 for the driving side and the operating side respectively. The sum of the reduction forces measured by the sensors 22A, 22B and the difference between the summary force and the standard total reduction force are calculated by an integrator 24, and further, the reduction forces to correct for the driving side and the operating side are calculated to execute the reduction control, based on the changing size of the roll gap and the total changing load. As a solidification at width direction is uniformized, the width of the thin hoop metal is uniformized.

摘要： PURPOSE: To obtain an excellent iron loss characteristic without dropping a magnetic flux density and without making a thin belt fragile by a method wherein Ta in a very small amount is added to an Fe-B-Si-based amorphous alloy. CONSTITUTION: A very small amount of Ta is added to an Fe-B-Si-based amorphous alloy. The composition of the amorphous magnetic alloy is expressed by Fea Bb Sic Tad , in which 70 atm. or higher. Then, the molten metal is annealed at a temperature of about 380 to 400 deg.C. Thereby, it is possible to obtain an amorphous magnetic alloy in which an iron loss is reduced by a strain-removing annealing operation and whose magnetic flux density is enhanced.

摘要： PURPOSE:To previously quantitatively evaluate the embrittlement degree of amorphous metal without restriction in a sample shape by quantifying the structural change amount generated in embrittlement of the amorphous metal by using a thermal analysis. CONSTITUTION:The specific heat of amorphous metal in a temperature range of its crystallizing temperature or lower is measured by a heat compensation differential scanning calorimeter with an amorphous metal in no embittlement state as a reference sample. It is preferable to set the temperature rising velocity at the time of measuring the specific heat to about 5-100km/min. On the other hand, a specific heat curve to become a reference is previously obtained, and a specific heat temperature curve in the temperature range of the crystalline temperature or lower of the amorphous metal sample measured by the calorimeter similarly is collated with the reference curve. The area change amount obtained from the change of a locus for the reference curve is used as the scale of the embrittlement degree.

摘要： PURPOSE:To produce a rapidly cooled solidified alloy thin strip having excellent surface characteristics by holding the part near the part where an injected molten metal accumulates in a gaseous atmosphere consisting of a prescribed compsn. CONSTITUTION:This molten metal is injected from a molten metal nozzle 1 to form a molten paddle 3 between the molten metal and a cooling roll 2. The molten metal is rapidly cooled and solidified by extraction of the heat from the cooling roll 2b, by which a thin strip 4 is formed. At this time, carbon dioxide is blown to the paddle 3 by an injection nozzle 5 and nitrogen is blown by an injection nozzle 6 to the surface upstream of rotation of the cooling roll 2, by which the part near the paddle 3 is held in the atmosphere of the prescribed gaseous oxygen and carbon dioxide concn. The injection angle of the injection nozzle 6 is preferably at 0 to 50 deg..
