1. Structure of Nut Coke with Low Phosphorous 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: What is the density of coke?: Do you want to transport by rail? Ha ha, you might as well ask the freight forwarding clerk, he / she will tell you the various models of the volume and the weight can be installed, the conversion of the density of the pile is more accurate.

Q: Coke is how to produce, what is its purpose?: Natural coke. Coke can be obtained by high-temperature carbonization of coal:

Q: What is the reasonable standard of volatile content of coke: 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%.

Q: Why is coke used in blast furnace steelmaking?Why not use coal?: (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.(3) the role of the skeleton: the blast furnace smelting process occurs in the movement and interaction between the rising of the gas and the falling of the charge. The pellets, coke, iron ore, ore and other materials according to a certain proportion, and batch sequence into a blast furnace, blast furnace smelting in reducing atmosphere under the hot metal, after providing to the steelmaking plant of the steel-making.

Q: Listen to a lot of people say that steel is now coke is not true?: 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: What is the essential difference between coal and coke?: Coke]Coke is 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 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. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength, but requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.

Q: The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?: Of course, the sulfur content of coke is low. Coke quality requirements: two grade coke containing sulfur below 0.7%

Q: What does the M40% and M25% mean in the analysis of coke?: (2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)

Q: The coke is divided into several separate uses: Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke etc.), coke and calcium carbide with coke gasification. The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke.
