Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 連続圧延設備における板材接合部の板座屈防 止装置に関するもので、接合部の熱効率を向上させ、座 屈防止板の溶損や板材への溶着を防ぐことを目的として いる。 【構成】 接合すべき先行粗圧延材１１の後端部と後行 粗圧延材１２の先端部とを少し離して設定し、油圧シリ ンダ１６によって上下の各クランプ１７及びこれに装着 した座屈防止板１を各々の圧延材１１，１２の上面及び 下面に押圧して拘束する。座屈防止板１は粗圧延材幅方 向に櫛歯状の切欠部１ａを形成しておく。誘導コイル１ ３に高周波電流を印加通電し、先行粗圧延材１１の後端 部及び後行粗圧延材１２の先端部に板厚方向に貫通する 磁束によってその平面内に励起渦電流２０を発生させて 誘導加熱したのち、入側フレーム１５を油圧シリンダ１ ８により板材長さ方向に移動させ押圧接合を行なう。 (57) [Abstract] [Purpose] The present invention relates to a plate buckling prevention device for plate material joints in continuous rolling equipment, which improves the thermal efficiency of the joints and prevents the buckling prevention plate from being melted or welded to the plate material. Has an aim. [Structure] A rear end portion of the preceding rough rolled material 11 to be joined and a leading end portion of the following rough rolled material 12 are set apart from each other by a hydraulic cylinder 16 to prevent upper and lower clamps 17 and buckling prevention attached thereto. The plate 1 is pressed against the upper surface and the lower surface of each rolled material 11 and 12 to be restrained. The buckling prevention plate 1 is formed with comb-shaped notches 1a in the width direction of the rough rolled material. Induction coil 1 3 is applied with a high-frequency current, and an induced eddy current 20 is generated and induced in the plane by the magnetic flux penetrating the trailing end of the preceding rough rolled material 11 and the leading end of the following rough rolled material 12 in the plate thickness direction. After heating, the inlet frame 15 is attached to the hydraulic cylinder 1. The plate material is moved in the length direction by means of 8 to perform pressure bonding.
