1. Structure of Low price of coke coal metallurgical coke price with low sulfur met coke Description：
Coke is made by high temperature metallurgical coke for blast furnace smelting, casting and gasification. Occurring in the process of coking after recovery and purification of coke oven gas is a high calorific value of fuel, is an important industrial raw material in organic synthesis.
Hematite in the main ingredients of Fe2O3, namely, iron oxide.Fe2O3 in nature as variants known there are two more homogenous, namely alpha Fe2O3 and gamma Fe2O3, in which the mass fraction of Fe is about 69.9433034300%.The former stable under natural conditions, known as the hematite;Is better than the latter under natural conditions of alpha stable Fe2O3, in metastable state, called a magnetic hematite.Iron ore often contains classes with foreign matter like Ti, Al, Mn, Fe2 +, Ca, Mg, and small amounts of Ga and Co.Trigonal system, perfect crystal rare.Hematite crystals for steel gray, implicit crystal;Earthy red hematite.Streaks of cherry red color or fresh pork liver.Metal to a half metallic luster.Sometimes tarnish.Hardness 5 ~ 6.The proportion of 5 ~ 5.3.

5. FAQ
Q: How do we guarantee the quality of our products?
A: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.
- Q:Who knows the proportion of pig iron and coke used in Cupola
- There are doubts: blank parts output is too low.3, blank export rate: raw materials into melting after the formation of blank, under normal circumstances, the common casting investment for every 1 tons of pig iron, scrap steel and other major raw materials, the lowest to 85% iron, after casting output blanks, nozzle, nozzle, riser, riser for iron smelting water ratio of about 30%; blank standard export rate, nozzle, riser re melted continue after put into use; production enterprises invested 1 tons per dryer, iron scrap and other major raw materials to the lowest 85% of the hot metal, roughly the same with ordinary casting, casting blank after the (standard yield) for hot metal ratio is about 70%, water riser for hot metal ratio is about 15%, and the same outlet riser re melted after continued use.
- Q:What is the use of coke
- The physical properties of the coke coke coke screening composition, physical properties including bulk density, coke coke coke true relative density, apparent relative density and porosity of coke, coke, coke, thermal conductivity and specific heat of coke thermal stress, ignition temperature of coke, coke, coke thermal expansion coefficient of shrinkage, resistivity and permeability of coke coke. The physical properties of coke are closely related to its mechanical strength, thermal strength and chemical properties at room temperature. Following the main physical properties of coke: true density is 1.8-1.95g/cm3 0.88-1.08g/ cm3; apparent density; porosity is 35-55%; bulk density is 400-500kg/ m3; the average heat capacity is 0.808kj/ (KGK) (100 C), 1.465kj/ (KGK) (1000 DEG C); the thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C); ignition temperature (air) is 450-650 DEG C; dry ash free calorific value is 30-32KJ/g;
- Q:We would like to export a batch of coke, I would like to know what information is required for a permit
- Step 1: apply for an electronic key:The electronic key is equivalent to the enterprise identity authentication, after the application is similar to online banking U shield, the cost of 350 yuan. Including the physical Key ($150) and digital certificate price ($200), where Key is a one-time fee, digital certificates for the annual cost, valid for one year.
- Q:What is the density of coke?
- There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
- Q:What is the difference between coke and coking coal
- Coking coal is a kind of bituminous coal with a high degree of deterioration, and the thermal stability of the resultant colloid is good when the coke is produced separately. The block size of the coke is large, the crack is small and the strength is high
- Q:The chemical composition of coke m10.m25 refers to?
- The physical properties of coke and its chemical composition are mainly determined by the type of coal used and the coking process
- Q:What kind of coke is needed for smelting special steel
- It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnace
- Q:Coke in the whole process of steelmaking in the end is what to do, just to provide heat or carbon and other substances into steel or iron?In the study of coal classification inside, one is divided into coking coal, coking coal and coke as main, and then you see is steel or iron coke must material. What is not clear. In the end, out of coal mining is mainly used to burn energy extraction, or said that coal like oil can be converted into other products, which is a coke can convert?
- It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnaceAfter the hot metal to steel in converter against the general converter, scrap also need to add a certain amount of used to balance the heat. Hot metal and scrap are added to the converter after the oxygen lance for oxygen operation, the oxidation of oxygen to carbon in liquid iron, silicon, manganese, phosphorus, sulfur and some non-metallic inclusions to form steel. Adding lime, dolomite, iron oxide and mine slag and coolant is needed in oxygen at the same time. After the completion of steel smelting in the tapping process according to different requirements with the corresponding iron alloy steel, after also refining process.
- Q:Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke)
- Q:How to calculate the average particle size of coke
- That is, "(volume) of the table of the percentage, in addition to the corresponding boundary value", these values are added, then the countdown. For example, the boundary 0 to 1 has a value of 10%, between 1 and 2, and between 2 and 4 has a value of 40%, and between 4 and 8, then D (3,2) = / (0.1/0.5 + 0.3/1.5 + 0.4/3 + 0.2/6) = 1/ (+ + 0.2 + + + 0.13 + +) = 1/0.56 = = =
