Product Description:

    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 metallurgical coke (met coke) of 30-80mm, the NUT coke of 10 to 30 mm, coke breeze of 0 to 10 mm, and so on.

We can offer below grade met coke, origin from China.

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:What is the reasonable ratio of coal to coke
There are lignite, bituminous coal, anthracite, semi anthracite these categories. 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.
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:The chemical composition of coke is m10.m25
Abrasion resistance refers to the ability of coke coke can resist friction without generating surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, the influence of coke pore structure of abrasion strength M10 value determination method of.M40 and M10 was more in China the migon drum test in Germany. As shown in table 31-1.After the completion of the test, the sieve with the pore diameter of 40mm and 10mm screening, greater than the percentage of 40mm particle size is M40, less than 10mm of the particle size of the M10 value. The intensity of the provisions of China Metallurgical Coke indicators are shown in table 31-2.
Q:Coking tower and coke tower is what relationship?
Coking plant coal tower, primary cooling tower, cooling tower, etc.. The coal tower is used to store coal for coke oven. The cooling tower is used to cool the gas and cooling tower cooling water.
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:How to remove the bottom of coke steel
After high temperature sintering, and carbonization of things, glued to the pot, often with chemical methods.The most effective way to do this is by hand:Soak in hot water for a few hours (or a day and night).
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. In the steel-making pig iron sulfur content greater than 0.07% is waste. By blast furnace furnace into sulfur from 11% ore; 3.5% from limestone; 82.5% from coke, so coke is the main source of sulfur in charge coke. Sulfur directly affects the production of blast furnace coke. When the sulfur content 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 sulfur content of large and medium-sized metallurgical coke the blast furnace is less than 0.4 - 0.7%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the 0.02 - 0.03% or less
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:The difference between semi coke and coke
The difference between them is that the final temperature of the two, the use of different raw materials, product yield and product properties are not the same. Low temperature coke. Under the condition that the coal is isolated from the air, the product is heated to 500 to 600 DEG C to obtain the product. It uses the raw coal is lignite, metamorphic degree of coal, long flame coal and gas coal. The final purpose of the low temperature carbonization is to obtain high yield coal tar
