Product Description:

Nut Coke of Size 20-40mm for Ferro Alloy Plants


1. Structure of Nut Coke of Size 20-40mm 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:Purpose of using coke in iron making raw materials
Purpose as follows:1. Provide the heat required for the reaction2, do reducing agent, generate CO, at the same time itself can also restore the iron
Q:What are the requirements for the quality of coke in blast furnace smelting
Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 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%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%.3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary.
Q:What are the quality indicators of coke
Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). 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.
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:What is the difference between coking plant and coke plant
Production equipment and production processes are complex.Coke plant, generally only the coal into coke on it, so simple.
Q:Who can talk about the coke industry prospects?
But at present, the iron making technology without coke has not yet been relatively mature, and it is not dominant compared with the traditional ironmaking technology. Coke industry still has development prospects.
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
Q:Why is coke used in blast furnace steelmaking?
The role of coke in blast furnace steelmaking is as follows:(1) providing heat: the coke burns fiercely in the raceway in front of the tuyere of the coke oven, and the heat generated by the combustion is the main heat source in the process of blast furnace smelting.
Q:What kind of coke is needed for smelting special steel
The role of coke in blast furnace ironmaking can be summarized as follows: 1:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.
Q:Mechanism of carbon and coke is not the same as the price which high?
Now, carbon factory has been discontinued, I start the original work - cable maintenance. The first floor of the post is my hair, said all no empty words. A combination of equipment quality is too bad, and Beijing Shougang, cleaning the equipment of large and the fact they are and exactly the same. Beijing is a liar equipment. Zhang Lian do is a donkey trading, factory equipment do Ba Chau are defective, they sold to Beijing fake technology company. I was at his factory inspection equipment of Shougang crooks in the factory. They stay trapped the loss of numerous investors. I now have been unable to recover
