在辊式弯曲机上生产弯曲型钢,是轧钢上的一个新的技术方向。弯曲型钢的生产和使用,对节约金属上具有重大的经济意义。目前,我们国内对弯曲型钢的性能、品种、生产工艺及设备等;不论生产部门或使用部门都还很不熟悉。有必要加以广泛宣传和介绍,以引起冶金工业部门和使用部门的重视并推广弯曲型钢的生产和使用。一、弯曲型钢的特点近年来用带钢、薄板卷、热轧的和冷轧的薄钢板作为原料,在冷状态下加以弯曲而成弯曲型钢的新技术 The production of curved steels on roll benders is a new technical direction for rolling. The production and use of curved sections of steel is of great economic importance for saving the metal. At present, our domestic performance of the curved steel, variety, production technology and equipment; regardless of the production department or the use of departments are still not familiar with. It is necessary to make a wide publicity and introduction to attract the attention of the metallurgical industry departments and departments and promote the production and use of curved steel. First, the characteristics of curved steel In recent years with strip, sheet coil, hot rolled and cold rolled sheet as raw material, in the cold state to be bent into a new technology bending steel
