为适应国民经济的调整,造纸行业正在采用新技术。其中,增大造纸机烘缸直径的生产工艺就是一个新的突破。由于烘缸直径的增大和面板厚度的增加,给烘缸的焊接带来很多困难。其中,控制烘缸面板的焊接变形,成为烘缸制造中的关键。 In order to adapt to the adjustment of the national economy, the papermaking industry is adopting new technologies. Among them, increasing the production process of paper machine dryer diameter is a new breakthrough. As the dryer diameter increases and panel thickness increases, to the drying cylinder welding brings many difficulties. Among them, the control of the deformation of the dryer panel welding, drying cylinder manufacturing has become the key.
