 note = {The line-heating process by oxy-acetylene gas flame is extensively applied to the bending of thicksteel plates in fabrication of steel structures. But it is one of the difficult manufacturing techniques in the ship-building industry. In order to solve the technical problems in plate-bending process, a lot of investigations were conducted in the past 30 years in Japan. Although their results have been reported many papers concerning line-heating method, there are many problems remaining unsolved and is not used enough yet in automatic and efficient process of ship-hull plate-bending. The authors carried out the preliminary experiments on the effects of line-heating for the efficient method of plate-bending. The purpose of this study is to find a relation between several heating conditions and induced angular distortions. In this investigation the following facts were clarified; 1) It is necessary to consider the heating breadth for calculation of angular distortion. 2) Angular distortion is influenced by not only the difference of peak temperatures at heating sufrace and back surface but also the value of peak temperature at heating surface. 3) Angular distortion is affected considerably by the pre-heating due to heat conduction., 長崎大学工学部研究報告, 23(40), pp.55-64; 1993},
