Coke filter does not contain toxic and harmful substances, in acid and neutral are insoluble in water, compression wear resistance, have enough surface area and reasonable particle size distribution. Because coke filter has good solid particles keep ability, so it can improve the reliability of the suspended particle removal ability, suitable for drinking water and industrial water filtration.
Coke is mainly used in blast furnace and used for copper, lead, zinc, titanium, imony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, heating agent and columnar skeleton. Blast furnace with coke instead of charcoal, laid the foundation for the large-scale modern blast, is an important milepost in the history of metallurgy. In order to make the operation of blast furnace achieved good technical and economic indexes, smelting with coke (coke) must have appropriate chemical and physical properties, thermal properties in the smelting process.
