The Dryer cylinder of the paper machine is one of the main equipment in the drying section. The dryer cylinder of the paper machine is an alloy cast iron pressure vessel, which is mainly used to dry wet paper. Its importance is self-evident.
From the analysis of the paper machine Dryer cylinder structure, the cylinder surface width is about 1.1-4.5m, and the diameter is 1-4m. The middle cylinder of the dryer is a cylindrical shell of equal thickness, and the end covers on both sides are one. The flat shell with variable thickness and curvature. The cylinder body and the end cover are connected by bolts. The load is mainly saturated steam input through the shaft head of the paper machine. In addition, a pressurized roller acts on the cylinder of the paper machine. , Thus forming a linear load acting along the axis of the cylinder, so the paper machine dryer material cast iron is a brittle material, used as a pressure vessel, it needs special attention when using it.
