1. Structure of Metallurgical Coke of Coke Strength after Reactivity 65 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) 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?

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 ℃.

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: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:What are the national standards for grade two coke?
Volatile content is not greater than 1.80; crushing strength: M40:76.1 - 80, M25:88.1 - 92; wear resistance: M10: not more than 8.5;
Q:How coke is involved in steelmaking,
. It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace according to a certain proportion, batch and order
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
There is no containing copper sulfate solution with tin. Because the copper iron can be displaced from the salt solution in their description, copper and iron;To sum up, we can know that C, Al, Cu, Fe four elements of the order of activity is Al > C > Fe > Cu;The answer is: Al > C > Fe > Cu.
Q:Coking tower and coke tower is what relationship?
Coking plant production capacity on the exclusion of the tower is also on the two: first, the coal tower; the two is coke bin;
Q:The difference between coal and coke
The semi coke production tend to low temperature carbonization, distillation temperature at 600 degrees Celsius, due to a late start, at present the low temperature carbonization furnace single furnace annual output of 30 thousand tons / year in most equipment under low temperature carbonization furnace forum of more than 50 thousand tons / year scale is still at the exploratory and experimental stage, technology of the large-scale equipment is still not mature, can only achieve centralized mass production using a combination of multi furnace technology. The use of coal field is quite widespread, especially in the carbonaceous reducing agent has unique properties, economic advantages are very obvious.
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 is the difference between coke and coking coal
Coking coal is a kind of bituminous coal with a high degree of deterioration, and the thermal stability of the resultant colloid is good when the coke is produced separately. The block size of the coke is large, the crack is small and the strength is high
Q:What is the difference between coking coal and coke
Coking coal is an essential raw material for the production of coking coal, coking coal is one of the main uses of coke, coke is full of coking coal, coking coal is necessary for coke.
Q:The difference between coke and coal
This is the nature of coal from the formation of coal is coal, and coal deep-processing products
