Blast Furnace Coke Hardness Mineral Processing & Metallurgy

Changes in coke hardness affect the working of the blast furnace, for soft coke is an obstacle to proper furnace operation Soft coke is due to a low hydrogenoxygen ratio in the coal charged; increasing this ratio increases the hardness of the coke The best means of determining the hardness of coke is the combined tumbler and ballmillBall hardness is in the 60–67 HRC range They wear better than 440C stainless steel and throughhardened carbon steel They are also recommended for applications where a throughhardened steel ball is needed in larger sizes (½" and larger) They are sometimes packaged with a very light oil finish to reduce rust due to humidityGrinding Media & Grinding Balls | Union Process, Inc
