Product Description:

1. Structure of NUTCoke of Size is 20--40 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:It was concluded that the following two facts: coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore
Coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore, indicating that aluminum is the most active
Q:What is the amount of waste gas produced by a ton of coke burning
Metallurgical coke with high carbon content, high porosity, high strength (especially high temperature strength), is an important fuel and reducing agent of blast furnace ironmaking, but also the entire blast furnace pillar supporting agent and loose agent
Q:With the number of 1 tons of steel smelting coke
Because it can reduce energy consumption and reduce costs. So in the iron and steel enterprises coke rate decreased as the main goal of public relations, all the staff for the blast furnace coke rate reduction efforts. A few data in Liaoning, the average coke rate of Anshan and Benxi, Anshan Benxi is 330kg/t, is 360kg/t, that is to say a pig needs 330 360kg and coke production 2 saddle of the iron and steel enterprises. Shanghai Baosteel coke for the best in the country, can reach about 280kg/t. Is about 280kg per ton iron coke, the national leading level.
Q:The chemical composition of coke m10.m25 refers to?
M10 refers to the wear resistance of coke, M25 refers to the crushing strength is the mechanical strength. Mainly the cold strength of coke. Coke is also the most important indicator is the hot state, CRI thermal reaction and CSR reaction intensity. In blast furnace production, both cold and thermal strength are important.
Q:Why does Coke provide heat during ironmaking?
In addition to the reaction of iron and iron oxide will react C+O2=CO2; reaction exothermic;
Q:Coke is how to make it? What is the use?
Improving the coal preparation process is the way to expand the coking coal source and improve the quality of coke. At present, most of the coking plants in China adopt the mixed grinding process. This process can not be treated according to the different hardness of coal, so it is only suitable for the coking coal with good caking property and uniform coal quality. A new coal preparation process has three kinds: single comminution process is various, coal crushing alone first, and then according to the provisions of the proportion, then mixing; the first group grinding process, hardness of similar kinds of coal, according to the proportion of each group, were sent to the respective crushing requirements the particle size, then mixing the crushing process; is crushed to a certain degree of coal sieving, the coarse grain group screened were crushed again, so that the coarse grain group cohesiveness, inert material with high content of ground fine, avoid good bonding facies excessive grinding components.
Q:Coke can be used to do what carbon black can be used to do?
Carbon black in plastics industry is the first use of carbon black pigment coloring, is cheap. Second carbon black in plastics industry use is to have good ultraviolet absorption effect, its application shows quite obvious protective effects in plastic. Third carbon black in plastics industry use is conductive.
Q:How long should it be to store coke in the open air
And the most important thing is to avoid the sun. Coal and coke, like the sun, the temperature inside the stack is very high. So try to cool down.
Q:Effect of coke powder ratio on the index
2, the phosphorus content of coke: iron metallurgical coke content should be 0.02 - 0.03%.3, coke ash: blast furnace coke ash effect is very significant. The amount of coke ash in coke increased by 1%, an increase of 2 - 2.5%., therefore, a decrease in coke ash is necessary4, coke volatile: according to the coke can be judged by the volatile content of volatile volatile is greater than 1.5%, then the coke; volatile less than 0.5 - 0.7%, which means that too much, generally mature volatile metallurgical coke to about 1%.5, coke moisture: moisture fluctuations should not be measured in coke, causing fluctuations in the furnace conditions. In addition, increased M04 coke moisture content high, low M10, the drum index error
Q:I'd like to have a coke
Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage.
