1. Structure of Nut   Coke   with   Normal   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.

Our country's metallurgical industry has a long history, is the original fuel charcoal smelting industry, due to the charcoal burning temperature is lower, and short duration of fire and not easy to master hour, therefore, directly affect the level of smelting, to make the steel quality is not guaranteed. Later, people use coal as smelting, coal combustion temperature is higher, and the combustion duration is longer than charcoal, but easily broken after coal is heated in the oven, affect the burden of permeability, and high content of sulfur in coal, directly affect the quality of the cast iron. After a period of practice, it has been found that the coal after dry distillation (i.e., separated flame heating), volatile components may be removed, and the porosity increased, resembling charcoal, fire is better than that of coal, but also can avoid charcoal and coal. This after carbonization of coal is coke.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

1) What are coke's main physical properties?

on the relative density of density, coke, coke porosity, thermal conductivity for the heat capacity of coke, coke, coke, coke ignition temperature, coke thermal expansion coefficient of thermal stress and coke, coke shrinkage rate, coke resistivity permeability, etc.

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 ℃.

2) 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.

3)Main type

Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.

Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.

In China, "natural coke" used as a fuel. Underground coal seam spontaneous combustion, and can also form natural coke. Natural coke, the grey to dark grey color, more porous, can sometimes show hexagonal prism shape. Compared with artificial coke, weight big, small porosity, density.


Q: Various types of coal coke are the main test items
If you need to test coal, caking index (G value), glial layer (X, Y) and other indicators, the index also includes the detection of more coal ash melting point (ash melting), hydrocarbon, the Hardgrove grindability index of coal, burning, swelling, activity, Oaxaca coal coal. Slag index.
Q: What chemical plant used to coke
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: F.C Ash S V.M H2O SizeMore than 85 less than 15 less than 8 less than 0.8 less than 1.5 10-70mm over 90%,I would like to ask, what is the size of the corresponding coke? Metallurgical coke or something else, there is no relevant information about, thank youF.C = 85, Ash = 15, H2O = 8, S = 0.8, V.M = 1.5, Size:10-70mm 90% and above, so clear, like the product, the current price?
Metallurgical coke indicators are as follows:A metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur;
Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?
In addition to the reaction of iron and iron oxide will react C+O2=CO2; reaction exothermic;
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: What is the amount of waste gas produced by a ton of coke burning
The coking coal is heated to 1000 DEG C under the condition of isolated air (high temperature carbonization)
Q: What is the difference between coke and carbon residue? Coke is a high-temperature refining, carbon residue can be used for civilian fuel it?
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: Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
Tomatoes to the bottom of the potNot a few good tomatoes in the pot boil, it will naturally fall.4, beer and liquor to the bottom of the potIf cooking is careful not to paste pot, the pot dish, if not easy to brush off, can pour a little wine and beer and a small amount of water (1:1:0.5 ratio) mixed cover, placed 5 minutes after it is easy to scrub clean.
Q: In the coke analysis index, M40% and M25% respectively mean what?
(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: How to determine the maturity of coke or not?
The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.
