Product Description:

1. Structure of Metallurgical Coke of MET COKE SIZE OF 30-80MM Description:

Sulfur content in coke: sulfur is one of the harmful impurities of iron smelting, it lower the quality of cast iron.The sulfur content in pig iron for steel making is more than 0.07% for the trash.By the blast furnace burden into furnace sulfur 11% came from the ore;3.5% from limestone;82.5% from coke, so coke is the main source of sulfur in charge.Coke sulfur content directly affect the blast furnace ironmaking production.When coke sulfur content is greater than 1.6%, sulfur, every 0.1% increase in coke consumption increased by 1.8%, increased by 3.7%, for the amount of limestone ore content of 0.3% by 1.5 - a 0.3% increase in the blast furnace production. The sulfur content of metallurgical coke is not greater than 1%, large and medium blast furnace using the sulphur content in metallurgical coke is less than 0.4-0.7%.

Q:Relationship between coke M40 and M25
Visible: the two are called coke crushing strength index, has a certain correlation. Coking coking coal coke, the two general values are relatively large, and vice versa.The specific number of relations, to specific measurement of different manufacturers of coke M40 and M25 values, statistical regression, in order to determine.
Q:Sulphur content of coal and coke,
The sulfur content of coking coal basically all into the coke, only a small number into the gas but the number is very limited. How much coal is the amount of sulfur in the general coal is the sulfur. It should be said that coke is basically a little lower and a little bit limited.In the process of coking volatile will be a lot of consumption, ash will increase 2-3%.
Q:The coke is divided into several separate uses
Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
Q:What is the density of coke?
The true density of coke: 1.8 ~ 1.95kg/cm3; apparent density: 0.8 ~ 1.08kg/cm3; pile density: 400 ~ 500kg/cm3
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:What is the difference between coke and coking coal
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed coal gas producer with solid slag discharging. It is used as the raw material to produce CO and H2 gas
Q:What is the essential difference between coal and coke?
(1) power coal(2) coking coal (bituminous coal)(3) coal used in coal chemical industry, which mainly includes gasification coal, coal for low temperature carbonization, hydrogenation of liquefied coal and so on.
Q:Coke coal charcoal are used for what
Coal:The use of coal is very extensive, according to the purpose of its use for three main purposes:(1) power coal,(2) coking coal,(3) coal used in coal chemical industry, which mainly includes gasification coal, coal for low temperature carbonization, hydrogenation of liquefied coal and so on.
Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
Coke GB/T 1996-2003, volatile coke is the most difficult to do
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.
