Product Description:

the Nut Coke of 20-50mm for Ferro Alloy Plants

1. Structure of the Nut Coke of 20-50mm for Ferro Alloy Plants 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:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
Quality index of cokeCoke is the solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index generally refers to the unit volume of the crack (crack number within the coke grain length). To measure the pore structure of the main indicators to measure with porosity (only coke pore volume accounted for percentage of the total volume) that it affects the coke reactivity and strength. The different uses of the coke porosity index for different requirements, the general metallurgical coke gas hole rate in 40 ~ 45%, foundry requirements in 35 ~ 40%, coke export requirements in 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 and coking coal as a base; Coke coal refining. Crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of two indicators. The coke crushing strength is that coke can resist foreign impact force without ability along cracks or defects at the broken table, shown by M40 wear; strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, M10 value and abrasion strength influence of coke pore structure. M40 and M10 were determined by lot. In China the migon drum test in Germany.
Q:Method for removing coke from nonstick pan bottom
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 semi coke production tend to low temperature carbonization, distillation temperature at 600 degrees Celsius, due to a late start, at present the low temperature carbonization furnace single furnace annual output of 30 thousand tons / year in most equipment under low temperature carbonization furnace forum of more than 50 thousand tons / year scale is still at the exploratory and experimental stage, technology of the large-scale equipment is still not mature, can only achieve centralized mass production using a combination of multi furnace technology. The use of coal field is quite widespread, especially in the carbonaceous reducing agent has unique properties, economic advantages are very obvious.
Q:Who can talk about the coke industry prospects?
With the rapid development of the domestic and international iron and steel industry, the demand for coking products is increasing rapidly, the investment is heating up, and the industry is expanding rapidly. But the coking industry of high resource consumption, production and emissions, especially the emissions of harmful substances, causing serious waste of resources and environmental pollution, brings great pressure to the sustainable development of national economy, which also hindered the rapid development of coking industry.
Q:Coke coal charcoal are used for what
Coke:The utility model is mainly used for blast furnace ironmaking and smelting of blast furnace for non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc.. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. 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:Why does Coke provide heat during ironmaking?
Generate CO2;Of course, high temperature will produce CO, but not many;Please ask questions
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 cokeWhat applications are, what is the fire of Malachite copper
Coke is a kind of reducing agent (C), under the heating conditions and some of the oxidation reduction reaction, can restore some important minerals, such as steel mills, etc..
Q:What are the requirements for coke and other accounts?
Futures account opening process1, customers need to carry the original natural person identity card or temporary identity card (must be within the validity period), at least any one settlement bank (China bank, agricultural bank, industrial and commercial bank, construction bank, Bank of Communications) debit card or passbook, to the Futures Company branch or the securities business Department (IB) personally.2, the signing of the "futures trading risk statement", "futures brokerage contract", "bank transfer", "letter of credit" and other agreements, to provide the phone, contact address and postal code.
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.
