Product Description:


1. Structure of Metallurgical Coke of Coke Strength after Reactivity 62 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.

2. Main Features of the Metallurgical Coke of Coke Strength after Reactivity 62:

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 main purpose of the use of coke
(1) heating.The heat needed for blast furnace smelting is provided by the combustion of coke and fuel, and the hot air is provided, and the heat of coke combustion accounts for 75% ~ 80%. The ash content of coke is low, and it still keeps a certain degree before falling to the tuyere.
Q:Coke boiler belongs to coal-fired boiler
In addition, the utility model is characterized in that the utility model is used for heating and catering industry. Generally speaking, coke boiler belongs to coal fired boiler. Reason is that coke is a coal and fat coal for coke production.
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:China's coke iron smelting began in what time?
The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool
Q:What are the ingredients of coke
Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage. 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.
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 is the difference between coking coal and coke
Therefore, coke is not coking coal, coking coal is one of the products after processing
Q:What is the effect of coke moisture on the blast furnace?
1, a large number of high coke moisture (when the rain open storage of coke in blast furnace smelting coke), if not timely load back down, will cause a relatively large impact on the furnace, coke is better then no timely adjusting load will cause heat phenomenon.
Q:What's the connection between coking coal and coke
Coking coal is divided into two categories, the first category of coking coal dry ash free volatile Vdaf>10% ~ 28%, G>65 bond index, thickness, y = 25mm. This part of the coking coal is particularly good, can separate the qualified blast furnace coke. Another kind of coking coal dry ash based volatile Vdaf>20% ~ 28%, caking index G>50 ~ 65, coking than the former difference. Coking coal is a kind of typical coking coal, which has a good thermal stability
Q:Coke is how to produce, what is its purpose?
Coke is a color of deep gray to black solid, soft; internal structure of porous, and sometimes can be six square column.
