1. Structure of Metallurgical Coke of Coke    breeze    of    size    0-10mm Description:

Iron ore is the important raw materials of iron and steel production enterprise, natural ore (iron ore) after crushing, grinding, magnetic separation, flotation, re-election and other procedures gradually selected iron.Is containing iron or iron compounds can economic use of mineral aggregate.

The world's iron ore resources concentrated in Australia, Brazil, Russia, Ukraine, kazakhstan, India, the United States, Canada, South Africa and other countries.China as the world's largest iron ore demand and its own iron ore reserves is not less, but unfortunately low grade, from an industrial economy perspective, rather than from Australia, Brazil and other countries is rich in the rich iron ore imports.

Q:The cost of iron ore and coke
At present the general level of building materials enterprises, the price of 2400 yuan / ton steel
Q:The difference between semi coke and coke
Coke strength is poor, poor permeability, high temperature performance is poor, the use of a large risk, easy to cause fluctuations in blast furnace conditions. Prices are relatively cheap. Low temperature coke and high temperature are all coal products.
Q:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
The following indexes: Metallurgical Coke metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur; two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile "1.9% full" water; 6%; "three sulfur 0.7%; metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6%" 1% "water; sulfur;
Q:What are the main uses of coke
A small smelting industry, used to produce calcium carbide, carbon disulfide, phosphorus etc.. In the iron and steel enterprises, coke powder is also used as sintering fuel. Coke can also be used as raw material for the preparation of raw materials for the synthesis of water gas.   4, in order to make the blast furnace operation to achieve better technical and economic indicators, smelting coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties.
Q:The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,
Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
Q:Standard grade two grade coke standard
Quality index of cokeCoke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). 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). The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test.
Q:Coking coal, coke, coal, steam coal what is the difference?
Coal is used to generate electricity, which is used to burn coalPower coal is generally only coal
Q:What is coke? What is the use?
In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength. But requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
Q:What is the reasonable standard of volatile content of coke
11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.
Q:Effect of coke powder ratio on the index
6, the size of coke in the blast furnace, coke screening is very important. We used the coke size requirements: large oven coke particle size greater than 40mm (1300--2000 square meters); small blast furnace coke particle size greater than 25 mm. But experiments show that some steel mills, coke size 40--25 mm good. More than 80mm of coke are screened to little change in the size range. This fragmentation of the coke uniform gap, small resistance furnace is running well.Purpose: various specifications of Shanxi foundry coke, metallurgical coke, coke car or high sulfur transport cars online sales. The specific indicators are as follows:Fixed carbon 83 or above; sulfur less than 0.5; 1.5 or less volatile; ash about E:Focal mechanism:Violin coke size 8 cm -150 cm:Metabituminous:Bulk modified coke:Size of 25 cm:
