Sep 25, 2018· The strength and density of coke is particularly important when it is used in a BF, as the coke supports part of the ore and flux burden inside the BF. Metallurgical coal possesses the ability to soften and re-solidify into a coherent, porous mass, when heated from 300 deg C to 550 deg C in the absence of air in a confined space.
Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most expedient. There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.
Sep 26, 2015· Petrographic analysis of coal is a major tool for predicting coke strength. The important properties of coal for the prediction of coke strength are as follows. Crucible swelling number (CSN) The range of CSN in coking coals is 3 minimum to 6 maximum. Prime coking coals have higher CSN values while soft coking coals have low CSN values.
