Product Description:


1. Structure of Metallurgical Coke of  10-15mm Low Sulfur Met Coke  Description:

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.Blast furnace with coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.For the blast furnace operation to achieve better technical and economic indexes of metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the nature of the thermal state in the smelting process.Coke in addition to a large number of used in ironmaking and smelting non-ferrous metal (metallurgical coke), also used in casting, chemical industry, calcium carbide and ferroalloy, its quality requirement is different.If foundry coke, general demand big granularity, low porosity, high fixed carbon and sulfur content is low;Chemical gasification with coke, lax to strength requirement, but it requires good reactivity, high ash melting point;Calcium carbide production with focal requirements to improve the fixed carbon content as much as possible.

limit production rate in more than 50%, some small coking plant maintain only coke oven heat preservation.

5. FAQ

1)Do you have a warehouse?

yes,we have.

2)How about your company?

Our company began to export coke when China cancelled 40% of coke export tariffs and quotas on January 1, 2013. We export many kinds of coke, such as CSR60 % and CSR 62% metallurgical coke (met coke), the NUT coke of 20 to 50 mmcoke breeze of 3 to 6 mm, and so on.

Q:Effect of coke powder ratio on the index
Quality index of cokeHigh temperature carbonization coke is the solid product, its main ingredient is carbon, the pore structure of spores (or pore porous) with crack and irregular crack. Have a direct impact on how much strength and crushing strength of coke, the index of crack usually (crack length per unit volume of coke in the index) to measure indicator. Pore structure is mainly used for measuring the porosity of spores (pore volume percentage of the total volume of coke) said that it affects the reactivity and strength of coke. The coke used for different purposes, the porosity index requirements change, but it usually requires 40 to 45% metallurgical coke porosity, casting requirements of 35 to 40%, the export of coke need to crack about 30%. coke with high and low levels of porosity, the use of coking coal has a direct relationship, such as gas refining is mainly coke, crack, high porosity, low strength; as in coking coal Break the coke refining base of small, low porosity and high strength. The strength of coke is usually the crushing strength and abrasion resistance of two indexes to represent the strength of coke can be broken. No cracks or defects and M40 values along the fault reference external shock resistance structure; wear strength of coke coke refers to the ability to form glass the surface resistance to foreign friction and no fragments or powder, expressed as the value of M10. The degree of M40 crack coke compressive strength affect the value, value of pore structure of coke impact wear resistance of M10 spores. The determination of M40 M10 and a lot of value, many German migon drum test our method.
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 = = =
Q:The chemical composition of coke m10.m25 refers to?
M10 refers to the wear resistance of coke, M25 refers to the crushing strength is the mechanical strength. Mainly the cold strength of coke. Coke is also the most important indicator is the hot state, CRI thermal reaction and CSR reaction intensity. In blast furnace production, both cold and thermal strength are important.
Q:How to distinguish the level of coke. What is metallurgical coke
Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Other more specific can see here:
Q:The coke is divided into several separate uses
Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. The metallurgical coke quality standard (GB/T1996-94) developed in China is the quality standard of blast furnace.
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:Types of coke and use of coke
China's coking industry has been formed with conventional machine coke oven blast furnace ironmaking production of metallurgical coke, with heat recovery coke oven production machinery foundry and foundry
Q:Coke crushing equipment prices, manufacturers offer is how much
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%.
Q:I'd like to have a coke
Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage.
Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
Two, the type of coke:Coke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.1, metallurgical coke, 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.The metallurgical coke quality standard (GB/T1996-94) made in China is the quality standard of blast furnace
