我厂回转窑矩形滚圈电渣焊接成功,是高举“鞍钢宪法”旗帜,大搞群众运动,发扬自力更生、艰苦奋斗的革命精神所取得的丰硕成果。1969年,我们总结了手工焊接断裂滚圈的经验,受万吨水压机电渣焊接立柱等部件的启发,成功地解决了用两台电渣焊机对称焊接两个半滚圈以后,又进一步解决了四块90°滚圈 The success of electroslag welding of rectangular rolling circle of rotary kiln in our factory is a fruitful result achieved by holding high the banner of “Ansang Steel Constitution”, carrying out mass movements and carrying forward the revolutionary spirit of self-reliance and hard work. In 1969, we summarized the experience of hand-welding broken coils, inspired by electroslag welding columns such as 10,000 tons of hydraulics, and successfully solved the problem of symmetrically welding two and a half rollers with two electroslag welders Four 90 ° rollers
