摘要铸造生产是由多工序组成的连续生产过程，为了有效地满足用户对产品质量要求，实现企业提质降耗的目标，必须对所有工序进行综合控制。尤其在大批量生产模式下质量控制的有效性对企业产品的竞争力至关重要，建立网络环境下的质量控制系统，可以及早发现问题并控制产品的质量。根据黄石某铸造有限公司有关铸件批量生产模式，对网络环境下的质量控制技术进行了分析，提出了适用于批量生产模式质量过程控制的实现方法。系统设计了数据采集、管理、分析的整体解决方案，有效地实现了产品质量的过程控制，并实现了基于Web的质量控制系统，对DISA造型生产线生产的各工序的质量进行综合控制，达到以最低成本制造出符合用户要求的优质产品并保证如期交货的效果。关键词：实时信息；质量监控系统；迪砂造型线AbstractCastingproductionisasuccessiveprocessconsistingofmanyworkingprocedures．Inordertomeetuser'sdemand，improveproductqualityandreducethecost，allworkingproceduresshouldbecontrolledsynthetically．Thevalidityofqualitycontrolespeciallyundervolumeproductioniscriticaltothecompetitivenessofproducts．Buildingqualitymonitoringsystemunderwebcanfindtroubleearlierandcontrolqualityofproductsassoonaspossible．BasedonthemodelofoneDISALtd．ofHuangshiandanalysisofthequalitycontroltechnologyunderweb．thispaperproposesthemethodofrealizingqualitycontrolundervolumeproduction．Thewholeprojectdesignsthesolutionstodataacquisition，managementandanalysis，whicheffectivelyrealizesthecourse—controlofthequalityunderweb．BysyntheticallycontrolingeachworkingprocedureinDISApatternproductline，highqualityproductscanbeproducedatthelowestcost，bothmeetingthedemandsofusersandguarantyingtheconsignmentinduetime．Keywords：real-timeinformation；qualitymonitoringsystem；DISApatternproductline目录1绪论.....................................................................................................................................11.1引言................................................................................................................................11.2国内外铸造生产线质量监控系统的发展现状...................................................11.3论文的课题背景及意义............................................................................................31.4论文研究的内容与价值............................................................................................42总体框架结构设计........................................................................................................52.1基于实时信息的铸造生产线监控系统的主要任务及组成............................52.2基于实时信息的铸造生产线监控系统的关键技术..........................................62.3基于实时信息的铸造生产线监控系统的总体框架设计.................................73SPC质量统计分析与预测..........................................................................................93.1SPC技术原理...............................................................................................................93.2SPC分析与监控阶段................................................................................................154基于实时信息的生产线监控系统......................................................................184.1各生产流程监测仪器设备的选用........................................................................184.2数据的收集与分析...................................................................................................204.3信息的反馈与修正..............................
