Water porous media at the national level high adsorption coke coke factory outlets

High temperature carbonization coke is a solid product, the main ingredient is carbon, the spore pore structure (or hole spore porous body) has cracks and irregular. Crack little direct impact on the strength and the crushing strength of coke, the index generally crack degree (referring to the crack length per unit volume of coke within the number) to measure. Indicators hole spore structure is mainly used to measure the porosity (pore volume of coke only a percentage of the total volume) to represent it affects coke reactivity and strength. Coke for different purposes, the indicator of porosity, generally the porosity metallurgical coke requirements in 40 to 45%, Foundry requires 35 to 40 percent, coke exports should be around 30%. The level and degree of coke crack porosity, the use of coal and coke has a direct relationship, such as the gas coal refining was mainly coke, crack and more high porosity and low strength; and to serve as a basis coking coal coke smelting was crack small, low porosity, high strength. Coke strength usually crush strength and abrasion resistance two indicators to indicate. Coke filter is mainly used in the blast furnace and for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting blast furnace, a reducing agent, heating agent and the material column skeleton. Blast furnace using coke instead of charcoal, laid the foundation for large-scale modern blast furnace, it is a major milestone in the history of metallurgy. For the blast furnace operation to achieve better technical and economic indicators, metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties. In addition to a large number of coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and ferroalloy, their quality requirements vary. Such as foundry coke, general requirements for large size, low porosity, high fixed carbon and low sulfur; chemical coke gasification, strict requirements for strength, but requires that the reaction is good, high ash melting point; carbide production coke requirements maximize the fixed carbon content.

Coke strength usually crush strength and abrasion resistance two indicators to indicate. Coke crushing strength refers to the coke resistant to external shocks without the ability to force structure cracks or defects broken along with the value represents M40; abrasion resistance of coke coke refers to resist foreign Friction force without producing surface capacity glass chips or powder form, is represented by M10 value. Crack of coke crushing strength M40 affect its value, pore structure of coke influence spore abrasion resistance M10 value. Determination of M40 and M10 a lot of value, our use of German 米贡 drum test method.
