摘要： PROBLEM TO BE SOLVED: To provide a continuous bright annealing technique of a steel strip, in which the development of new defective shape in the strip width direction caused by the load of conveying tension is restrained, at the time of correcting the deformation in the longitudinal direction of the strip developed in a cold working. SOLUTION: A position, at which the steel strip 1 during conveying in a catenary type tension annealing furnace reaches the temp. corresponding to the boundary part for changing from the elastic deformation with the load of the conveying tension in a heating zone 2 to the plastic deformation, is obtd. A support roll 9 is arranged at the portion in the elastic deformation range side adjoined to the boundary part and the steel strip 1 is annealed by acting resisting force with the support roll against the compression stress acted in the width direction of this steel strip 1 at the position of the steel strip 1 in contact with the support roll 9 and also, the shape of the steel strip 1 is corrected.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a low thermal expansion alloy for electronic parts, free from the occurrence of inferior etching, such as striped irregularity, which causes local deterioration in image visibility and capable of high precision etching. SOLUTION: The cross-sectional shape of a prism-shaped steel ingot composed of an Fe-Ni alloy containing 30-45 wt.% Ni and prepared by the ingoting process or a prism-shaped slab composed of the above alloy and prepared by the continuous casting process is regulated so that the ratio of the length (b) of the side in a rolling direction to the length (a) of the side perpendicular to a rolling direction, b/a, becomes >=0.6. The ingot or slab is slabbed at >=50% draft or forged and then subjected to hot rolling and cold rolling.

摘要： PURPOSE:To execute cold-rolling to an electromagnetic steel sheet into profile having good cross section in the sheet by adjusting angle of tapered part at one side of working roll and overlapping length of the tapered part and sheet end part according to (Si+Al) content in the electrical steel sheet to be rolled. CONSTITUTION:At each one side of barrel part in the upper and lower working rolls 1a, 1b, the linear tapered part 2 is formed so as to be point symmetry between both rolls and both rolls are made shiftable in the arrow mark roll axes direction. By using this rolling mill, the cold-rolling is executed to the electrical steel sheet 3. In the above rolling method, the angle of the above tapered part 2 and the overlapping length of the tapered part 2 and sheet end part in the sheet width direction are adjusted according to (Si+Al) content in the above steel sheet 3 to be rolled. By this method, without developing breakage of the sheet, crack of the sheet end part, edge drop, etc., the electrical steel sheet 3 is rolled to obtain the profile of good cross section in the sheet.

摘要： PURPOSE:To roll a plate to a desired sectional profile by determining the shape of the convergent part of work rolls in accordance with a profile transfer rate and controlling the sectional shape of the plate. CONSTITUTION:The difference in radius between a reference point O (the start point of a general roll caliber) and the work roll 2 at the distance X from the end of the plate 1 is designated as R and the rolling reduction of the material to be rolled as t. The transfer rate P is P=( t/ R)X100%. The value of P is determined by the plastic deformation characteristics, such as deformation resistance, including the working history of the plate, the roll deformation including local deformations and the transverse distribution of a draft, etc. The value is determined theoretically or by actual measurement. The sectional shape in the longitudinal direction of the roll barrel in the convergent part of the work roll 2 is determined by referring to this value so as to obtain an arbitrary or desired sectional profile.
