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.

Coke is mainly used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, compound and the function of stock column frame.

Blast furnace with Coke instead of charcoal, which laid a foundation for the large-scale of modern blast furnace, is a major milestone in the history of metallurgy.

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?

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) 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.

Q:What is the main purpose of the use of coke
(1) heating.The heat needed for blast furnace smelting is provided by the combustion of coke and fuel, and the hot air is provided, and the heat of coke combustion accounts for 75% ~ 80%. The ash content of coke is low, and it still keeps a certain degree before falling to the tuyere.
Q:Various types of coal coke are the main test items
Coal test items which specific indicators of coal test:Generally include coal test indicators include: calorific value of coal (calorific value), sulfur content (sulfur), ash, volatile, fixed carbon, char residue characteristics, total moisture, water analysis and other indicators
Q:Who knows what the provisions of the coke train sampling country?
Methods for determination of moisture content of coke, a method of introduction of a certain quality of coke samples, placed in a drying box, drying at a certain temperature to a constant quality. Calculation of the percentage of water content in the mass loss of the coke sample. Two. Reagent color silica gel: industrial products
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:Why use coke instead of carbon in blast furnace ironmaking
The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace, the CO reduces the iron oxide, and the part of CO burns, and the whole process will release a lot of heatCheck information, combined with the knowledge of the professional knowledge, for reference purposes only!
Q:How many degrees of coke ignition temperature can ignite coke
Ignition temperature (450-650) in air;Dry ash free base low calorific value is 30-32KJ/g;The specific surface area is 0.6-0.8m2/g
Q:Is the power plant using coking coal or coke?
According to the use of coal can be divided into: injection coal, coal, coal coking coal can be divided into: lean coal, coking coal, gas coal, fat coal, lignite in five categories. Coking coal is used to refine coke. The power plant's coal coal power coal can also be said that under normal circumstances, can not be used for coking coal can be used to make electricity.
Q:Coke is divided into several kinds of specifications ah
Three: 1 2 3 coke metallurgical coke of high sulfur cokeCoke is in coal under the condition of air isolation, heating to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). 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.
Q:What is the use of coke
A definition of English Name: Coke, coke metallurgical coke blast furnace coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
Q:Types of coke and use of coke
The vertical furnace processing of low metamorphic coal production of calcium carbide, ferroalloy, coke, chemical fertilizer production and ultra high power electrode, aerospace and medical high technology and high value-added products such as carbon needle coke the world's most complete and unique characteristics of the Chinese coking industrial system.
