Product Description:


1. Metallurgical Coke of Coke Strength after Reactivity 64 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 mmcoke breeze of 3 to 6 mm, and so on.

Q:What is the difference between coke and carbon residue
Coke concept:Bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should Have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. In the steel-making pig iron sulfur content greater than 0.07% is waste. By blast furnace furnace into sulfur from 11% ore; 3.5% from limestone; 82.5% from coke, so coke is the main source of sulfur in charge coke. Sulfur directly affects the production of blast furnace coke. When the sulfur content 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 sulfur content of large and medium-sized metallurgical coke the blast furnace is less than 0.4 - 0.7%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the 0.02 - 0.03% or less
Q:What does Coke test index M25 mean?
. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10, our method using migon drum test in Germany.
Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
6, the horizontal type coke oven drying machine(7) gas purification circulating water.... supporting technology(8) dry cooling technology of interlayer water-cooled steam.(9) microcomputer precise dosing system
Q:Why does Coke provide heat during ironmaking?
Yes;To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;
Q:What is cokeWhat applications are, what is the fire of Malachite copper
Malachite is a kind of copper, copper smelting with coke burning malachite is under high temperature.
Q:I'd like to have a coke
Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on.
Q:Coke is divided into several kinds of specifications ah
(Lord Jiao Meilian) {for precision casting and ductile casting for} fixed carbon above 86; sulfur ash is below 0.5; 12; 1.5: volatile fiddle coke grain size 4cm--8cm or above 10cm: fixed carbon furnace for {}} setting common casting coke particle size 25cm:{for precision casting and ductile casting for 3 more than 88 tons of sulfur ash; 0.5; 10; 1.5: volatile foundry coke particle size 25cm:{type applicable to the above all high precision ductile casting export and international index: {8cm} fiddle coke for common casting and casting products such as strict fire pump fittings; fasteners such as high fixed carbon above 788385} sulfur: {for copper, aluminum, plastic, chemical coke} fixed carbon above 83 gas coal coke: {for carbon monoxide gas extraction, rich gas} fixed carbon about 78 coal coke: {casting parts annealing, Coke, coke, civilian chemical copper, aluminum, plastic} fixed carbon about 65 coke, coke coal: {civil casting parts of annealing, chemical coke}
Q:What is the phosphorus content in coke
Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
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
