摘要： PROBLEM TO BE SOLVED: To provide an isothermal forging method which can simply, easily and surely maintain a material temperature in a die to a prescribed level, can surely prevent a material from being overheated above the prescribed temperature by fairly holding a processing speed during forging, can process a high-strength, high-toughness and high-quality component at high speed by micronizing a crystal grain, can eliminate heat-treatment after processing to minimize post-processing work, and thus is excellent in mass productivity.
SOLUTION: The isothermal forging method includes the steps of: heating the die; measuring and monitoring a die temperature; controlling the heating temperature in the die heating step so as to converge and maintain the surface temperature of a die inside to the processing level of the metal material on the basis of the temperature measured in the die temperature-monitoring step; heating a solution-heat-treated metal material to a temperature of ≥100°C to its recrystallization temperature or below; and forging the heated metal material by charging in the die whose temperature is controlled to a processing level in the above heating temperature-controlling step.

摘要： PROBLEM TO BE SOLVED: To minimize a deviation from the base material part of a weld zone material concerning the surface characteristics of a roll by making the carbon quantity of the deposited metal of a weld zone a level by which a crack does not generate even when welding by a welding method with a high heat input in an internal layer area covering the greater part of a thickness on the inside surface side of the cylindrical body of the weld zone, also a level by which quench hardness equivalent to the part of the base material of the cylindrical body is obtained in the external layer area of a remaining thickness. SOLUTION: In a manufacturing method for a cylindrical body closing in a cylindrical shape by connecting by welding the straight tip edges of the base material of the cylindrical body constituted by one body bent by bending a metallic plate or constituted by plural bodies, first of all, after forming a primary weld zone by performing welding covering the greater part of a thickness positioning on the inside surface side of the cylindrical body of the weld zone or covering the whole thickness by a welding method with a high heat input by a filler metal whose carbon quantity is 0.05 to 0.20%, a desired groove for a secondary welding is formed by grinding and reshaping the outside surface side of the cylindrical body of the primary weld zone.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of gap liable to be caused in end parts of a welding surfaces, and to excellently weld the whole welding surface when the end parts are diffusion-welded to each other. SOLUTION: In this method, when a welding system in which end faces of metals are butted to each other through an insert are heated and raised in temperature above the melting point of the insert, the compression force orthogonal to the welding surface is applied to the welding system by a plurality of cycles for a short time, a part in the vicinity of the welding surface is plastically deformed, and the end faces are closed attached to each other through the insert to achieve the excellent liquid phase diffusion welding of the whole end faces. By repeatedly applying the compression force for a short time, the butted metals are prevented from being misaligned in the thickness direction.
