Product Description:

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.

Bituminous coal under the condition of the air, heated to 950-950 ℃, after drying, pyrolysis, molten, bonding, solidification and contraction phase resulting coke, this process is called high temperature coking (high temperature carbonization).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.

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:Coke and coal is one thing
Coke is bituminous coal under the condition of isolated air, heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, solidification, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization).Coke is a deep processing of coal products.
Q:What information is needed for coke export license
1, the Ministry of commerce website download and fill in the import and export license enterprise electronic key application form".2, fill in the application form, the "Registration Form for foreign trade dealers original and copy" or "foreign investment enterprise approval certificate original and copy" and "for the people of the Id original and photocopy" issued by the Department of foreign trade and economic cooperation when sending license, receiving approval.3, through the examination and approval, notify the enterprise payment. The examination and approval authorities will fax to Beijing materials guofuan e-commerce security certification of the company, making the electronic key by guofuan company, guofuan company will make a good electronic key, the installation and use of CD, invoice and electronic key receive confirmation etc. three express mail to the examining and approving authority for the examination and approval organ shall notify the enterprise.
Q:Standard grade two grade coke standard
Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 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:What is the effect of coke moisture on the blast furnace?
2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa
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:How much coke is needed for a ton of iron
Iron ore in blast furnace, mainly iron and oxygen compound. At high temperature, the carbon monoxide produced in the coke and the carbon dioxide in the injection and the carbon monoxide generated by the carbon capture the oxygen in the iron ore, which is called the reduction. The iron ore is used to produce pig iron by reduction reaction. The gangue in the iron ore, the ash in the coke and the spraying material and the flux of the limestone in the furnace are combined to generate the slag, and the slag is discharged from the taphole and the slag outlet respectively. The gas is derived from the top of the furnace, which is used as industrial gas after dust removal. Modern blast furnace can also use the top of the high pressure, with the export part of the gas power generation.
Q:Who can talk about the coke industry prospects?
Steelmaking is definitely not coke, but now most of the very mature iron making technology needs coke, the future direction of development of iron is not used or less coke
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:What is the essential difference between coal and coke?
[coal]Coal is a kind of solid combustible mineral which is buried in the underground plants and has been formed by the complex biochemical and physicochemical changes. Coal is a kind of solid combustible organic rock, which is mainly formed by the chemical reaction of the remains of plants.
Q:How coal is turned into coke in the coking chamber
Simply put is to let the coal in the isolated air furnace heating, volatile volatile, and the rest is cokeOf course, the volatile ingredients to be collected, are the baby
