铜闪速熔炼冶金计算程序研究

摘要：闪速炉系统是一个庞大的复杂系统，其生产具有高度非线性、多环节、多操作变量的强烈耦合性，熔炼过程具有系统动力学特性的不确定性和对控制性能的高依赖性，使用传统的人工经验判断和探索性的试生产的方法很难满足闪速熔炼过程的不断优化的要求，因此充分利用现代计算手段的先进性和具有普遍性的模型技术在闪速炉熔炼生产中显得十分重要。物料平衡计算和能量平衡计算应用在工业生产的各个领域、各个阶段：在生产之前操作参数的优化需要输入物料的组成，在实际生产过程中需要进行配料和配风的计算。对于一个已建成的闪速炉系统，其生产气力究竟有多大，又主要受到哪些因素的制约，如何在生产过程中协调各环节因素以实现系统的最佳匹配等，这些问题已成为各闪速炉用户关注的一大焦点。为了适应生产强化的要求，更好的协调系统配置，科学地挖掘闪速炉生产潜力，本文通过对铜闪速熔炼过程中物料平衡及能量平衡计算的研究，建立了相应的衡算模型，建立并完善了闪速炉数值熔炼模型，开发了Matlab计算程序。

The research of Metallurgical calculation in

Copper Flash Furnace

Abstract: Flash smelting Furnace system is a large complex system, its production has the important character of the strong coupling of high nonlinear, multi-link, and multi-variable operation. Smelting process has the uncertainty of the system dynamics and the high dependence on the performance of control. Using the traditional artificial judging by experience and exploratory way has cannot meet the request of the continuous optimization for the flash smelting process, therefore, it is very important to take full advantage of the advanced modern computing means and universal model technology in the production of flash smelting furnace. The calculations of material balance and energy balance are used by various fields and various stages of industrial production: the optimization of operating parameters before production need for inputting the composition of materials. The calculations of the feed and the volume of blast are needed in the actual production processes. For a completed flash furnace system, how much productivity it has? What is the main factors ? How to adjust various aspects of factor so that the system can has the best match in the production process. All these problems have become a major focus of concern for the flash Furnace users. In order to adapt to the requirements of the enhanced production, better coordinated system configuration, and scientifically Mining production potential of flash furnace, the paper set up a model of accounting, mathematical model of balance calculation of the flash smelting furnace through the study on the material balance calculation and energy balance calculation for the copper flash smelting process. Meanwhile, it developed a MATLAB program.

Keywords:Flash smelting Furnace; material balance; heat balance; mathematical model of balance calculation; program
