1. Structure of The Metallurgical Coke of Size is 30 -- 80 mm 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.

5. FAQ
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:How to remove the bottom of coke steel
- So that the whole place to restore the original black dye can be done.Water sandpaper rubbing can of course, but in the end to more than 1000 mesh water sandpapering. Another 100 clean cloth polishing line. The coke on the stove can only be removed by hand.Finally, wash the rice cooker, stove, as well as your tired hands, thoroughly washed several times. Here, everything is back to normal, as if nothing had happened.
- Q:How coal is turned into coke in the coking chamber
- The kiln chamber wall set to continue burning, and some heat incoming kiln (indirect heating). High temperature gas flow (800 DEG C, is mixed with coal pyrolysis, chemical products into the fabric of unburned.
- Q:After the long-term use of non stick pan, oil stains can not be effectively removed, over a long period of time in the non stick coating on the formation of a layer of coke, the effect of losing non stick. As a result of this layer of coke is relatively dense and smooth, scouring cloth has been ineffective, steel ball can not be used to damage the coating, what chemical or physical methods to remove this layer of coke?
- Four, wash the metal wire ball friction force discoloration, and always use water to clean out the dirt.So that the whole place to restore the original black dye can be done.Water sandpaper rubbing can of course, but in the end to more than 1000 mesh water sandpapering. Another 100 clean cloth polishing line. The coke on the stove can only be removed by hand.Finally, wash the rice cooker, stove, as well as your tired hands, thoroughly washed several times. Here, everything is back to normal, as if nothing had happened.
- Q:The difference between coal and coke
- The production of coke products in general is mainly based on high temperature carbonization, and the carbonization temperature usually needs about 1000 degrees celsius. After years of development, the current large-scale coke furnace equipment and technology is relatively mature, have equipment to improve the yield so as to achieve large-scale production conditions, coke furnace built in recent years, each with a yield of about 500 thousand tons, the highest can be even more than 1 million tons / year, such as the recent launch of mine international coking plant two chamber coke oven 7.63 m, each with a yield of 1 million 100 thousand tons per year.
- Q:In the coke analysis index, M40% and M25% respectively mean what?
- (2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)
- 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:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
- Orange to the bottom of the potCut a few slices of orange into the pot boil, stuffy night, second days will be turned over the paste paste, it is easy to clean up.7, the old telephone card, magnetic card washing paste potProblem Description: run out of phone cards, shopping cards, discount cards, VIP cards piled up, although there are people who love this kind of thing, but most people had no interest, so, or use it to do something. When cooking is paste pot, if made of hard coke fouling cleaning shovel, cause scratches with the wooden shovel, and difficult to completely remove the coke fouling. Why not let those old cards reflect the use value?Method of operation: with the card along the edge of the pot, and gradually remove the coke scale clean. Note that when you do not need to force too hard. If the card is made of hard plastic, can also be used to scrape the dirt on the gas stove.
- Q:Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers
- To be exact, you don't need coke for steelmaking, you say that it's iron making
- Q:What does the M40% and M25% mean in the analysis of coke?
- M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
- Q:What are the main uses of coke
- Main use of coke:1, is the most important coking products, more than 90% countries most coke used in blast furnace, blast furnace with coke instead of charcoal, laid the foundation for the large-scale modern blast, is an important milepost in the history of metallurgy.
