1. Structure of Metallurgical Coke of Coke Strength after Reactivity 62 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) 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.

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:What is the difference between metallurgical coke and chemical coke
Chemical coke:Chemical gasification coke, the intensity of the requirements are not strict, but requires a good reaction, high ash melting point; calcium carbide production requirements for coke to improve the fixed carbon contentQuality index of coke
Q:What is the essential difference between coal and coke?
(1) power coal(2) coking coal (bituminous coal)(3) coal used in coal chemical industry, which mainly includes gasification coal, coal for low temperature carbonization, hydrogenation of liquefied coal and so on.
Q:China's coke iron smelting began in what time?
The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool
Q:Coking coal, coke, coal, steam coal what is the difference?
Coking coal is the raw material for coke
Q:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
Formed coke is a product obtained through several steps:(1) environmental protection continuous high efficiency carbonization furnace(2) the use of anthracite powder to produce plastic molding coke and supporting technology(3) a new type of environmentally friendly carbonization carbonization furnace without three wastes discharge.(4) hydraulic press
Q:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
The following indexes: Metallurgical Coke metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur; two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile "1.9% full" water; 6%; "three sulfur 0.7%; metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6%" 1% "water; sulfur;
Q:Who knows what the provisions of the coke train sampling country?
Three, instrument and equipment of drying box: with automatic temperature adjusting device, can maintain the temperature of 170 DEG C and 105 a 180 a 110 C, the tray is made from galvanized sheet iron or aluminium sheet, size is about 300mm x 200mm X 20mm. The glass weighing bottles: diameter 40mm, high 25mm, and a grinding cover tightly. Dryer: inside the color of silica gel or granular anhydrous calcium chloride
Q:Why use coke instead of carbon in blast furnace ironmaking
The role of coke in the blast furnace: 1 reducing agent 2 heating agent 3 skeleton role. Combined with the effect of coke in the blast furnace can know compared with coke instead of charcoal. The coke oven gas is produced high calorific value of fuel, and is an important raw material for organic synthesis industry.
Q:What are the main uses of coke
Main use of coke:1, is the most important coking products, more than 90% countries most coke used in blast furnace, blast furnace with coke instead of charcoal, laid the foundation for the large-scale modern blast, is an important milepost in the history of metallurgy.
