我单位是一个原材料供应部门,每年冶金用原材料费用比重很大。如何在保证原材料的功能的前提下降低成本呢?应用价值工程技术达到了此项目的。 一、以原煤代替洗精煤生产焦炭 1985年我厂炼焦用洗精煤缺少15.95万吨,煤炭部规定计划外超发洗精煤加价20％,这样全年要多 My unit is a raw material supply department, a large proportion of the cost of raw materials for metallurgy each year. How to reduce the cost under the premise of ensuring the function of raw materials? Application value engineering technology to achieve this project. First, the coal instead of coal washing coal production coke In 1985, I plant the lack of 159,500 tons of coke clean coal, the Ministry of Coal provides unplanned extra-clean coal fare increase of 20%, so that more throughout the year
