Coke obtained from high temperature coking is used for blast furnace smelting, casting and gasification. Coke produced in the process of recovery, purification of coke oven gas is both high calorific value of fuel, but also an important organic synthesis of industrial raw materials.Commonly size: 0.5-1, 1-2, 2-4, 4-6, 6-8, 8-16mmFeatures of the coke:Large adsorption capacity.Large specific surface area.Chemical stability.Long service cycle.Usage of the coke:Coke filterCoke filter because of its high mechanical strength, multi-porosity, good adsorption performance, sewage interception ability, coke filter to remove suspended solids in water, water purification, has a very good effect. Coke filter is widely used in chemical, steel, oil, printing and dyeing and other industrial water treatment coke filter.metallurgical cokeCoke is mainly used for blast furnace ironmaking and for the copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal blast furnace smelting, from the reducing agent, heaters and column skeleton role. Ironmaking blast furnace using coke instead of charcoal, laid the foundation for the modernization of modern blast furnace, metallurgical history is a major milestone. In order to achieve good technical and economic indicators for blast furnace operation, smelting coke (metallurgical coke) must have appropriate chemical and physical properties, including the thermal properties in the smelting process. Coke in addition to a large number of iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and ferroalloy, its quality requirements are different. Such as casting with coke, generally require large particle size, low porosity, fixed carbon and low sulfur content; chemical gasification with coke, the intensity is not strict, but requires good reactivity, ash melting point higher; calcium carbide production requirements Try to increase the fixed carbon content.Fuel grade cokeSpecification of the coke:Fixed carbon80-86%S1%Ash12%Moisture1.6%V.M.1.5%P0.003%Porosity 79.5%Hydrochloric acid dissolution rate0.86%Note:S of the coke: S is one of harmful impurity of the iron smelting. If the S content above 0.07%, the iron will be waste product.P of the coke: The P content should be bellow 0.02-0.03%, when you iron smelting.Ash of the coke: The ash add 1%, the coke need add 2-2.5%.Volatile matter of the coke: According to the content of the volatile matter we could adjust the grade of the maturity of the coke. Moisture of the coke: Moisture will make the M40 on the high side and make the M10 on the low side.Size: A. Coke powder: 0-1, 0-3mmB. Coke granular: 5-25mmC. Coke block: 25-80mmGraphite carburizing agentWith the continuous progress of metallurgical technology, in order to adapt to the intensification of smelting process, the requirements of high quality and efficiency of steelmaking technology, in a ladle recarburizing agent has been widely adopted as a supplementary means, our factory developed the development of molten steel carburetion agent with high fixed carbon content, low content of sulfur and increasing carbon effect is stable, the recovery rate is high, the smoke is less when using, do not pollute environment and is an ideal material for molten steel carburetion.High quality carburizing agent generally refers to after graphite carburant, in under the condition of high temperature and carbon atoms arranged in graphite morphology, so called for graphitization. Graphite can reduce the content of impurities in the carburant, enhance the carbon content, reduce the content of sulfur and nitrogen.Specification of the graphite carburizing agent:Commonly size0-10, 1-5, 5-8mmFixed carbon98.5%S(Normal)0.05%S(Low)0.03%N(Normal)700PPM(0.07-0.01%)N(Low)150-300PPM(0.015-0.03%)Moisture0.5%Ash0.5%V.M0.5%Petroleum CokeThe petroleum coke is carbonized by petroleum coke calcination and purification. The appearance is round or prismatic, with metallic luster, porous, carbonaceous. Petroleum coke is characterized by high carbon and low sulfur, low ash, metallurgical chemicals, machinery, electricity and other industries ideal carbon material and reaction intermediates, petroleum coke is a widely used carbon agent. Petroleum coke increased carbon converter converter smelting, high carbon steel in the use of impurities with little oil coke as a carbon agent, the top blown converter smelting just with carbon requirements is fixed carbon is high, ash, volatile and Sulfur, phosphorus and other impurities to be low, and to dry, clean, moderate size of the carbon agent, the particle size is too easy to burn easily, too thick to join after the molten steel surface is not easy to be absorbed by molten steel. Petroleum coke is refined by crude oil by-product, crude oil distillation or vacuum distillation of the residue and oil asphalt, can be used as a raw material for the manufacture of petroleum coke, and then get the coke after the oil coke. The production of petroleum coke is less than 5% of the crude oil used, and the high content of impurities in the petroleum coke can not be directly used as the carbon agent and must be calcined. The calcination of petroleum coke is to remove sulfur, moisture, and volatiles, and the raw petroleum coke is calcined at 1200 to 1350 ° C to make it a substantially pure carbon. The largest user of calcined petroleum coke is made of aluminum, and 70% is used to make an anode that reduces bauxite. China's production of calcined petroleum coke, for cast iron to increase the amount of carbon agent accounted for about 6%. Raw oil coke in the high content of impurities, can not be directly used as a carbon agent, must be calcined, the petroleum coke calcination is to remove the sulfur, moisture, volatile, the raw petroleum coke at 1200-1350 ºC calcination can make it Basically pure carbon. Calcined petroleum coke is widely used in industry, can be used for steelmaking, ironmaking, general casting and other industries, can also be used as casting on the brake disc, crankshaft, brake pads and so on.Specification of the petroleum coke:Commonly size1-5mmFixed carbon98.0%S(low)0.05-1.0%S(Middle)1-2%S(High)2-3%Moisture0.5%Ash0.6%V.M0.5%Brake pad manufacturing:size----40-120, 30-150, 20-100mesh.
