摘　　要：我公司1#纸机流浆箱为气垫式流浆箱,因提速要求,气垫压力升高后出现压头不稳定的现象,从而影响到浆料上网成形时流速及成形质量的稳定。我们通过对流浆箱气垫压头控制系统的改进,使气垫压力得到稳定控制,产品质量也得到了较大提高。Headbox of BM1 is air-cushioned headbox. In order to increase the machine speed, it is necessary to increase air cushion pressure of the headbox. Keeping stable higher total air cushion pressure becomes a tough work to have good performance of the stock flow on the wire-section and paperboard formation. We improved the autocon- trol system for air cushion pressure, and got stable total air cushion pressure. Product quality has been improved greatly.
