随着计算机应用的普及，计算机技术在冶金工程中也得到广泛的应用。冶金工程中的计算往往是运算步骤繁杂，原理简单，适于使用计算机运算。本文针对两种典型的工艺流程图进行了物料的有价成分平衡计算的计算机编程，并对所编的程序进行举例验证，程序运行结果与手工计算结果吻合。 With the popularity of computer applications, computer technology has also been widely used in metallurgical engineering. Calculations in metallurgical engineering are often complicated steps, the principle is simple, suitable for use of computer computing. In this paper, two kinds of typical process flow chart were carried out for the computer programming of the calculation of the valuable components of the material, and the examples of the program were verified by examples. The results of the program are in good agreement with those of the manual calculation.
