Product Description:

1. Structure of CNBM   Metallurgical   Coke  ---   30 to  80 mm Description

Coke is a hard texture, with carbon as the main component of irregular porous body, with cracks and defects in silver. The true density is 1.8 ~ 1.95 g/cm3, bulk density is 400 ~ 500 kg/m3, the porosity of 35% ~ 35%,.Coke all vertical and horizontal crack can be seen with the naked eye observation. The vertical and horizontal crack along the thick break, still is focal piece containing micro cracks.

Currently found in the earliest coke in our country, is in Guangdong new will be a unearthed in the ancient ruins in the late 13th century, during the southern song dynasty period in our country. Thus concluded that China's song dynasty, have been used to coke ironmaking. Guangdong new will find coke is also found that the earliest in the world. In Europe, the UK in 1788 began with coke ironmaking, this is the earliest record of western countries, the more than 500 years later than our country.

5. FAQ

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

1)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.

2) Application of coke

     Used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury

     Other non-ferrous metal smelting of blast furnace,

     Reducing agent, compound

     The function of stock column frame.

3) The history of coke

Currently found in the earliest coke in our country, is in Guangdong new will be a unearthed in the ancient ruins in the late 13th century, during the southern song dynasty period in our country. Thus concluded that China's song dynasty, have been used to coke ironmaking. Guangdong new will find coke is also found that the earliest in the world. In Europe, the UK in 1788 began with coke ironmaking, this is the earliest record of western countries, the more than 500 years later than our country.

Although the use of coke earliest in our country, but has not seen through the records. Coking and the earliest recorded with coke can be found in the late Ming dynasty in China side to write the physical knowledge, he pointed out that coal everywhere all have, "smelly burning-out and closed into stone, chisel and charging again yue reef (coke), May 5, fire, cook Fried mine stone, will save Labour". This smelly coal, it is to point to contain volatiles more coking coal, the coal sealed burning-out, becomes hard coke, used for smelting, the effect is very good.

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
Coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore, indicating that aluminum is the most active
Q:Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the comprehensive utilization of raw materials in the following process
(1) according to the definition of replacement reaction, there are two kinds of compounds in the reaction of II, contains two kinds of compounds in the product, so it is not the replacement reaction of reactants, IV no elemental, so it is not a replacement reaction, V reaction is a chemical reaction, I and III reaction with replacement reaction conditions, so is the replacement reaction,
Q:How to distinguish the level of coke. What is metallurgical coke
Coke type: coke 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
Q:The chemical composition of coke is m10.m25
Quality index of cokeThe quality index of coke coke [] is a solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index of general degree (refer to how to crack crack length unit the volume of coke in the measure.) to measure the pore structure of the main indicators for the porosity (coke pore volume only percentage of the total volume) that it affects the coke reactivity and strength
Q:What is the density of coke?
There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
Q:What chemical plant used to coke
. 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
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
4, coke in volatile coke: according to the volatile content of coke can determine maturity. Such as volatile than 1.5%, said coke; volatile matter less than 0.5 - 0.7%, said too much, generally mature metallurgical coke volatile is about 1%.5, the moisture in the coke: water fluctuation will make coke measurement is not allowed, thus causing the furnace condition fluctuation. In addition, coke moisture will increase the M04 high, M10 low, to the drum index error6, coke screening composition: grain size of coke in blast furnace smelting. It is very important to China in the past, coke size requirements: on the coke oven (1300 - 2000 square meters) of coke particle size greater than 40 mm; medium and small blast furnace coke particle size greater than 25 mm. But some mills tests show that the coke 40 - 25 mm in size as well. More than 80 mm coke to whole, little change in its size range. So the coke size uniform, large gap, small resistance, the furnace is running well.
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:What are the ingredients of coke
The chemical composition of coke including fixed carbon, ash, sulfur, volatile matter and moisture. Except moisture, other ingredients in dry coke as basis.
Q:What is the phosphorus content in coke
Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
