西南林业大学本科结课（设计）论文题目：111国造纸行业现状及发展趋势教学院（部）材料工程学院专业林产化工学生姓名艾麦尔玉荊・指导教师评阅人中国造纸行业现状及发展趋势摘要：制浆造纸生产的自动控制，过去应用的范围十分有限，主要集中在制浆过程的局部简单仪表控制和纸机的电气传动控制方而，大量的控制内容是通过现场人工调整实现的。改革开放以来，通过国外先进技术产站的引进，以及借鉴相关行业自动控制方面的经验，自动控制在造纸生产中逐步得到了应用，正朝着整厂集中控制的方向发展。近年来，许多厂家在生产过程的重点环节进行了自控系统的技术改造，如蒸煮控制、盘磨控制、配浆控制、丄浆流送控制、纸机传动、纸机干燥部多段通气控制（热泵控制）和水分定量检测等方而，取得了明显的效果。StatusquoanddevelopmenttrendofChina^spaperindustryAbstract:automaticcontrolofpulpandpaperproduction,thescopeofapplicationisverylimitedinthepast,mainlyintermsofthelocalelectrictransmissioncontrolsimpleinstrumentcontrolandmachinepulpingprocess,alargenumberofcontrolcontentisachievedthroughon-sitemanualadjustment.Sincethereformandopeningup,throughtheintroductionofforeignadvancedtechnologyproducts,aswellasdrawingontheexperienceoftherelevantindustryautomaticcontrol,automaticcontrolinpaperproductiongraduallybeenapplied,ismovinginthedirectionofthedevelopmentofcentralizedcontroloftheentireplant.Inrecentyears,manymanufacturersinkeyaspectsoftheproductionprocessofthetechnologicaltransformationoftheautomaticcontrolsystem,suchascookingcontrol,discrefinercontrol,withpulpcontrol,sizingapproachflowcontrol,machinedrive,papermachinedryingsectionmultistageventilationcontrol(pumpcontrol)andquantitativedetectionofmoisture,etc.,andachievedremarkableresults.目录1前言...............................................................12造纸行业现状及特点.................................................22.1制浆过程........................................................22.2造纸过程........................................................63制浆的工艺发展及存在的问题...........................................73.1原料的结构不合理，对外依存度高..................................73.2我国实施造纸原料木浆供应的必要性.................................83.3APP国“立足中国，绿色承诺”理念及宣言...........................84造纸行业发展趋势.....................................................94.1我国造纸行业大幅扩张.............................................94.2我国造纸行业市场空间大.........................................114.3国内纸业市场的竞争格局.........................................125造纸行业市场结构的发展趋势..........................................135.1集约化.........................................................135.2高档化.........................................................145.3林纸-一体不匕..................................................145.4多元化..........................................................156生产线的发展趋势....................................................156.1控制系统以现场总线为核心.......................................156.2全集成自动化思想................................................156.3现场总线........................................................166.4仪表（总线型变送器）............................................166.5控制内容的广泛性和控制方式的专业化..............................177小结论..............................................................19参考文献................................................................
