Alternate Cokemaking: Coal Compaction, Briquetting & Reverts
Due to high competition in the steel market, the trend is to use alternative materials in the mixture of coal. Charcoal was studied in order to produce coke that meets the specifications of blast furnaces, but with low cost. Charcoal is considered an inert material, but brings the great advantage of a low level of sulfur. Thus, through this work, we tried to analyze the changes in metallurgical coke properties caused by the addition of coal in different proportions and grain sizes. The results showed that, through the addition of thicker charcoal (70% <2.83) and up to 2% in mineral mix coals, it is possible to obtain high levels of mechanical strength in low-sulfur coke.
