摘要
铸造是获得机械产品毛坯――铸件的主要工艺,也是机械装备制造业生产
的重要基础环节。提高浇注的自动化程度,是实现高精度、高品质铸件生产的
技术保证,还是铸造工人从繁重的体力劳动和恶劣的生产环境中解脱出来的重
要技术手段。本课题采用激光定位、超声波液位测量技术、先进伺服驱动技术
以及人工示教方法,通过工业可编程序控制器(PLC )数字化平台,实现了自
动瞄准浇口杯,自动检测铁水液面变化,模拟人工示教方法自动完成浇注。在
线参数修正技术,实时补偿浇注包因铁水高温长时侵蚀挂渣所导致的浇注状态
的变化,进一步提高了倾转式自动浇注机控制的精确度,改善了自动浇注机的
性能。

Abstract
The founding is a principal technique and a importantly radical link of machine
equipment building , by which embryo of machine product―the foundry is made.
Heightening automation of pouring is a technical guarantee by which the producing
foundry is assured with high accuracy and quality, which is still the important
technical mean to free workers from strenuous manual labor and disgusting
circumstances. There are technologies of locating with laser which takes aim at the
poured cap automatically, of measuring the high degree of iron liquid in the pouring
container with supersonic, of advanced servomechanism driving and of artificial
teaching through manual work by imitating which the auto-making pouring is
completed, by digital intermediary of Programmable Logic Controller in my thesis.
Though the state of pouring has been changing for the pouring container corroded
by high temperature iron liquid, the changing parameters of pouring are
compensated at real time by the technology of parameters modified online, which
further enhanced the control accuracy to the tilting type auto-pouring machine ,
improved its function.
