摘要
目前,一些高性能钕铁硼磁性材料在烧结前需要在充满惰性气体的手套箱中保存,然后通过移动手套箱和烧结炉对接实现封闭式装料。但在操作方式上仍是各台炉子独立工作,炉子之间无信息交换,装料方式也是由现场操作者手动移动手套箱和炉子对接,完成对炉子的进出料,再根据炉子生产工艺,以手动模式执行对炉子的抽真空、加热、冷却等过程。在对生产设备的智能化改造过程中,可靠性、经济型和实用性一直是生产制造企业追求的目标,因此本文提出了一种基于西门子S7通讯的小型PLC网络在手套箱-烧结炉集群控制系统中的应用方案,可实现稳定、可靠的无人化控制管理。
At present,some high-performance NdFeB magnetic material needs to be stored in a glove box filled with inert gas before sintering.However,in terms of operation mode,each furnace still works independently,and there is no information exchange between furnaces.The charging mode is that the on-site operator manually moves the glove box to connect with the furnace to complete the feeding and discharging of the furnace,and then according to the furnace production process,the operator performs the vacuuming,heating and cooling manually.With the intelligent transformation of production equipment,reliability,economy and practicability have always been the goals of the production workshop.Therefore,this paper proposes an application scheme of small PLC network based on Siemens S7 communication in cluster control system for glove box-sintering furnace,which can realize stable and reliable unmanned control and management.
