1. Structure of Metallurgical Coke of Coke Strength after Reactivity 62 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.
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.

We have organized several common questions for our clients，may help you sincerely：
1) How to guarantee the quality of the products？
We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
2) What are coke's main physical properties?
The average heat capacity is 0.808 kj/(KGK) (100 ℃), 1.465 kj/(KGK) (1000 ℃)
Thermal conductivity is 2.64 kj/(MHK) (room temperature), 6.91 kj/(MHK) (900 ℃);
Ignition temperature (air) is 450-650 ℃.
3) 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 mm, coke breeze of 3 to 6 mm, and so on.
- Q:Can the sulfur content of coke affect the casting process of nodular cast iron at 0.65?
- The level of spheroidization is not enough. The final sulfur content of molten iron before the spheroidizing treatment is best at 0.03%
- Q:The coke is divided into several separate uses
- Gasification coke is used for the production of coke gas. The utility model is mainly used in a fixed bed coal gas producer with solid slag discharging, and is used as a gasification raw material to produce CO and H2 as combustible components. The main reaction of gasification process:C+O2 - CO2+408177KJ
- Q:Natural gas can replace coke smelting pig iron
- Coke at high temperature (also some blast furnace pulverized coal, heavy oil, natural gas and other auxiliary fuel) in carbon with bubbling air oxygen in the combustion of carbon monoxide and hydrogen generated in the furnace, removing the rise in iron ore in the process of oxygen, thereby reducing iron. The molten iron is released from the taphole. An iron ore, which is a mixture of non - reducing impurities, such as limestone, to form a slag from the slag. The produced gas is discharged from the top of the furnace, and is used as a fuel for a hot blast stove, a heating furnace, a coke oven, a boiler, etc.. Blast furnace smelting is the main product of pig iron, as well as by-products of blast furnace slag and blast furnace gas.
- Q:What is the reasonable ratio of coal to coke
- Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and carbon, hydrogen, oxygen and three of the total possession of more than 95% of the quality of the machine, is a very important energy, metallurgy, chemical industry is an important raw material
- 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:I see that there are metallurgical coke and coke on the Internet, what is the difference between them (I hope to be able to say in detail) and a level of two points, how is this going on?.. Where is the quality of coke in China? Hunan good coke plant which? Although the problem is a little bit more, I hope that insiders can give some useful information. Extremely grateful.
- Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough
- Q:What is the effect of coke moisture on the blast furnace?
- 1, a large number of high coke moisture (when the rain open storage of coke in blast furnace smelting coke), if not timely load back down, will cause a relatively large impact on the furnace, coke is better then no timely adjusting load will cause heat phenomenon.
- Q:How coal is turned into coke in the coking chamber
- Simply put is to let the coal in the isolated air furnace heating, volatile volatile, and the rest is cokeOf course, the volatile ingredients to be collected, are the baby
- Q:Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce
- The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace, the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!
- Q:How to determine the maturity of coke or not?
- The sulfur content of coke: refers to the percentage of sulfur content in coke. Sulfur is one of the harmful impurities in pig iron smelting. The sulfur content in the pig iron is more than 0.07%. 82.5% of the sulfur from blast furnace charge into the furnace comes from coke, so coke is the main source of sulfur. 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 by 3.7%, with the increasing of the amount of ore 0.3%, blast furnace production decreased 1.5 - 2%.
