1. Structure of the  NUT  Coke  of  Size is  20 –-- 50  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:Purpose of using coke in iron making raw materials
It can capture the oxygen atoms in iron oxide or magnetic iron oxide to form carbon dioxide. The reaction equation is as follows:3C+2 (Fe2O3) = ==3 (CO2) +2Fe at high temperature2C+ (Fe3O4) = ==2 (CO2) +3Fe at high temperature
Q:Coke indicators are divided into grades
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).
Q:Coke is divided into several kinds of specifications ah
Three: 1 2 3 coke metallurgical coke of high sulfur cokeCoke is in coal under the condition of air isolation, heating to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis. 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:In the coke analysis index, M40% and M25% respectively mean what?
M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
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%.
Q:What is the sample quantity of coke moisture test? What is the test time? How many degrees? That is the national standard.
Methods for determination of moisture content of coke, a method of introduction of a certain quality of coke samples, placed in a drying box, drying at a certain temperature to a constant quality. Calculation of the percentage of water content in the mass loss of the coke sample. Two. Reagent color silica gel: industrial products
Q:Coke and coal is one thing
Not the same thing.Coal is often said of coal, including bituminous coal, lignite, anthracite, etc.
Q:We would like to export a batch of coke, I would like to know what information is required for a permit
1, the Ministry of commerce website download and fill in the import and export license enterprise electronic key application form".2, fill in the application form, the "Registration Form for foreign trade dealers original and copy" or "foreign investment enterprise approval certificate original and copy" and "for the people of the Id original and photocopy" issued by the Department of foreign trade and economic cooperation when sending license, receiving approval.3, through the examination and approval, notify the enterprise payment. The examination and approval authorities will fax to Beijing materials guofuan e-commerce security certification of the company, making the electronic key by guofuan company, guofuan company will make a good electronic key, the installation and use of CD, invoice and electronic key receive confirmation etc. three express mail to the examining and approving authority for the examination and approval organ shall notify the enterprise.
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 role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.
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%
