人工计算复杂冶金流程是一项令人厌烦的工作。工程师在计算中很容易差错。人工计算流程不但费用高而且时间长。这就促使一些从事提取冶金研究、设计和建设的机构研究如何使用计算机解决流程计算问题。尽管化学工业流程设计的专用程序已经设计出来,但这些程序往往不能求解含固体颗粒的流程。Flour 矿业和金属公司研制成功一种新的计算机应用系统,专门用于矿物加工工业流程设计。这个系统采用了顺序模块化计算方法(the sequential modular Computationtechnique),可以积累成一个冶金过程程序库,供通用执行系统调用。应用这种计算方法,能够迅速计算新的工艺流程,编制附加程序的工作量很少。FLEXMET 流程求解系统的执行性能是本文的主题。这里考查的主要特点包括:人机对话输入数据处理,流程计算自动排序,单元作业模型的灵活适应,先进的循环管理和定值控制计算。
Manually calculating complex metallurgical processes is an annoying job. Engineers are prone to error in their calculations. The manual calculation process is not only expensive but also takes a long time. This has prompted some institutions engaged in extraction metallurgy research, design and construction to study how to use computers to solve process calculation problems. Although proprietary procedures for the design of chemical industry processes have been designed, these procedures often fail to solve the process of containing solid particles. Flour Mining and Metals Corporation has developed a new computer application system designed specifically for the design of mineral processing industrial processes. The system uses the sequential modular compution technique and can be built into a metallurgical process library for general purpose execution system calls. With this method of calculation, a new process flow can be calculated quickly and the effort required to program additional processes is minimal. FLEXMET process solving system performance is the theme of this article. The key features examined here include input data processing for human-machine dialogues, automatic sorting of process calculations, flexible adaptation of unit job models, advanced cycle management and set-point control calculations.
