洗精煤的含硫量对钢铁质量及环境危害极大。冶金部门在冶炼过程中为了把硫除去,以保证钢铁质量,在技术上要采取很多措施,在经济上付出较大代价。煤炭部门在制定洗精煤价格时,应充分考虑煤的含硫量这一因素,把硫在质量规格和价格上体现出来。现行的煤炭价格,是以洗精煤的灰分为基础,再根据洗精煤的煤种、水分、硫分等指标的不同,按一定比价率制定的。各项质量指标在价格中所占的比价率,是以煤在使用过程中,其在技术上所起作用的大小、经济效果的好坏来确定。但现行的计价办法中这些指标的比价率是否已经体现了它们在技术经济上的作用,做到了按质计价,还值得
The sulfur content of clean coal is of great harm to the quality and environment of the steel. Metallurgical departments in the smelting process in order to remove sulfur in order to ensure the quality of steel, in the technical measures to be taken to pay a higher price in the economy. In formulating the price of coal washing, the coal sector should give full consideration to the sulfur content of coal and reflect the quality and price of sulfur. The current price of coal is based on the ash of the clean coal, and then according to the coal washing, water, sulfur and other indicators of the different, according to a certain ratio. The ratio of the quality indicators in the price is determined by the size of the technical role played by the coal during its use and its economic effect. However, whether the ratio of these indicators in the current valuation measures has demonstrated their technical and economic role, that they are price-quality and worthwhile
