摘要:介绍了圆网纸机采用折流带压活动弧形板成形器、三辊半湿压光机，改换大辊径压榨，增加烘缸组，增设表面施胶机和压光机等系统的技术改造情况。生产实践表明，改造后，车速由改造前的95～130/min提高到95～230 m/min，日产量由改造前的35～45 t提高到100～135 t，且所生产的挂面箱纸板和瓦楞原纸档次得到了提高。

Abstract:The rebuilding experience of a cylinder machine is introduced in this paper. A cylinder machine consisted of a former with movable arc plate and zigzag flow was rebuilt, in addition to the original three rolls hemi-dry calender was replaced by a large diameter roll press and the number of drying cylinders was increased, a surface sizing press and a calender were newly installed. The speed of the rebuilt machine increased from 95~130 m/min to 95~230 m/min, and its capacity increased from 35~45 t/d to 100~135 t/d when packaging paper was produced.
