1. 如果纸板水分过高，预热辊温度达不到要求，须增加锅炉蒸汽压力，使之供出的蒸汽达到饱和蒸汽，一般情况下蒸汽压力应该保持在1.1Mpa±0.2Mpa。
1. If the moisture content of the paperboard is too high and the temperature of the preheating roller cannot meet the requirements, the boiler steam pressure must be increased to make the steam supplied reach saturated steam. Generally, the steam pressure should be maintained at 1.1MPa ± 0.2MPa.
2. 如果水分偏低，就要调节导纸辊，减少预热面积，同时要充分利用单面机上喷雾装置（湿润辊），对原纸进行喷雾，增加原纸水分，使之达到标准要求。
2. if the moisture is low, adjust the guide roll and reduce the preheating area. At the same time, we should make full use of the spray device on the single plane (Shi Rungun) to spray the base paper and increase the moisture content of the base paper, so as to meet the standard requirements.
3. 平板烘缸在工作时，不到万不得已时，不能停车。单面机要更换原纸前应提速，在桥架上增加堆积量；复合机在接到信号后应降速，待单面机完成接纸后，再行提速。若设备发生故障等必须停车时，应将输送带提升，以防停留在平板烘缸上纸板水分过度流失。
3. When the flat dryer is working, it cannot stop until it is absolutely necessary. Speed up the single-sided machine before replacing the base paper and increase the stacking amount on the bridge; After receiving the signal, the speed of the compound machine shall be reduced, and the speed shall be increased after the paper receiving of the single-sided machine is completed. If the equipment fails and must be stopped, the conveyor belt shall be lifted to prevent excessive loss of paperboard moisture staying on the flat dryer.
4. 对于单面机而言，要调节好上胶辊与刮胶辊的间隙。一般情况下，上胶辊与刮胶辊的间隙为0.2mm一0.25mm，涂胶辊与主瓦楞辊在热机状态下的间隙应比所用瓦楞纸的厚度大0.02mm。
4. For the single-sided machine, the gap between the upper rubber roller and the rubber scraping roller shall be adjusted. In general, the gap between the upper rubber roller and the rubber scraping roller is 0.2mm-0.25mm, and the gap between the rubber coating roller and the main corrugating roller under hot engine state shall be 0.02mm greater than the thickness of the corrugated paper used.
对于双面机而言，刮胶辊和上胶辊的间隙也为0.2mm一0.25mm，压辊与上胶辊之间间隙应比所通过的单面瓦楞纸板高度小0.05mm一0.1mm，且两辊两端间隙应保持一致，可用塞尺测量。
For the double-sided machine, the gap between the rubber scraping roller and the rubber feeding roller is also 0.2mm-0.25mm. The gap between the pressing roller and the rubber feeding roller shall be 0.05mm-0.1mm smaller than the height of the single-sided corrugated board passed, and the gap at both ends of the two rollers shall be consistent, which can be measured with a feeler gauge.
为了有效控制温度，在瓦楞纸板生产线上，很多地方都设置了加热器和烘干板。通常情况下，车速在100m/min以上的瓦楞纸生产线，糊液的固化温度应为160℃～180℃。如果采用蒸汽加热方式，则要求锅炉饱和水蒸汽的压力应达到0.9MPa～1.4 MPa。而瓦楞纸生产线上对瓦楞纸板含水量影响比较大的设备主要是单面机组和烘干机组。针对不同情况，应该随时对这些部分做出相应的调整，以便生产的顺利进行。
In order to effectively control the temperature, heaters and drying boards are set up in many places on the corrugated board production line. Generally, the curing temperature of the paste solution of the corrugated paper production line with a speed of more than 100m / min shall be 160 ℃ ~ 180 ℃. If steam heating is adopted, the pressure of saturated steam of boiler shall reach 0.9mpa ~ 1.4mpa. The main equipment on the corrugated paper production line that has a great impact on the water content of corrugated board are single-sided unit and drying unit. According to different situations, these parts should be adjusted at any time to facilitate the smooth progress of production.
