摘要

冶金煤分为炼焦用煤和高炉喷吹用煤粉两类。炼焦煤最重要的特性是由技术分析(挥发物产量、灰分含量等)和决定高炉焦炭质量的冶金特性决定的。对于煤粉来说,重要的参数是由技术分析、热值和研磨指数决定的。冶金煤的需求取决于生铁的产量,而生铁的产量又取决于地区特点。即使在绿色议程时代,冶金煤仍有其优势。冶金煤供应量的增长预计将持续到 2030 年。这些煤炭大部分来自澳大利亚、俄罗斯和蒙古。俄罗斯正在实施几个大型煤炭项目(ELSI、Kolmar、Severnaya Zvezda)。目标是出口煤炭,尤其是出口到亚洲。根据作者的预测,在不久的将来,俄罗斯每年的出口量将增加 2000 万吨。全球煤炭价格取决于处于历史高位的生产成本。如果全球价格下跌,市场将迅速做出反应,因为高成本供应商将被赶出市场,限制供应,全球价格将回升。

Global Market for Metallurgical Coal

The two categories of metallurgical coal are coal for coking and pulverized coal for injection in blast furnaces. The most significant characteristics of coking coal are those determined by technical analysis (yield of volatiles, ash content, etc.) and the metallurgical properties determining the quality of blast furnace coke. For pulverized coal, the important parameters are those determined by technical analysis, the calorific value, and the grinding index. Demand for metallurgical coal depends on the output of pig iron, which, in turn, depends on regional characteristics. Even in the era of the green agenda, metallurgical coal retains its benefits. Increase in the supply of metallurgical coal may be expected to continue until 2030. Most such coal comes from Australia, Russia, and Mongolia. In Russia, several large coal projects are underway (ELSI, Kolmar, Severnaya Zvezda). The goal is to export the coal, especially to Asia. Russian exports will increase by 20 million t per year in the near future, according to the authors’ predictions. Global coal prices depend on production costs, which are at historically high levels. If global prices fall, the market will respond speedily, as high-cost suppliers are driven from the market, restricting supply, and global prices rise again.
