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.

5. FAQ
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: Standard grade two grade coke standard
- 2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%.3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary.4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%.
- Q: What is cokeWhat applications are, what is the fire of Malachite copper
- Coke is used for heating, and coke is also used as a reducing agent to process the iron ore, the oxide ore, the malachite is the copper oxide
- Q: The chemical composition of coke is m10.m25
- Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand is about 30%. The crack and porosity of coke and coking coal for the level, which has a direct relationship, such as coal based coke refining cracks, porosity, high strength, low; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is used to denote the crushing strength and abrasion resistance of the two indicators.
- Q: Used in a restaurant?Dry or dry carbon carbon, coke or coke, and I do not know which word is a word of this sound. The use of coke for iron making. They are more than 1000 yuan price.The main problem is: dry carbon is coke?Toxic smoke, then the chimney can not do? Can I use the blower?
- Dry carbon is not coke, but the combustion will produce a lot of harmful substances, it is recommended to install a more advanced cleaning device. Thank you
- Q: What are the main uses of coke
- A small smelting industry, used to produce calcium carbide, carbon disulfide, phosphorus etc.. In the iron and steel enterprises, coke powder is also used as sintering fuel. Coke can also be used as raw material for the preparation of raw materials for the synthesis of water gas. ??4, in order to make the blast furnace operation to achieve better technical and economic indicators, smelting coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties.
- Q: Effect of coal fineness on coke
- The fineness of pulverized coal, which is less than 3mm of grain size, has a great influence on the quality of coke. The fineness of coal is one of the indexes of coal blending quality. In the production, when determining the fineness of coal, we should consider two aspects of the quality uniformity and production operation.
- Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?
- Generate CO2;Of course, high temperature will produce CO, but not many;Please ask questions
- Q: What is the use of coke
- The physical properties of the coke coke coke screening composition, physical properties including bulk density, coke coke coke true relative density, apparent relative density and porosity of coke, coke, coke, thermal conductivity and specific heat of coke thermal stress, ignition temperature of coke, coke, coke thermal expansion coefficient of shrinkage, resistivity and permeability of coke coke. The physical properties of coke are closely related to its mechanical strength, thermal strength and chemical properties at room temperature. Following the main physical properties of coke: true density is 1.8-1.95g/cm3 0.88-1.08g/ cm3; apparent density; porosity is 35-55%; bulk density is 400-500kg/ m3; the average heat capacity is 0.808kj/ (KGK) (100 C), 1.465kj/ (KGK) (1000 DEG C); the thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C); ignition temperature (air) is 450-650 DEG C; dry ash free calorific value is 30-32KJ/g;
- Q: What is the effect of coke moisture on the blast furnace?
- The influence of coke moisture on blast furnace can be divided into two parts:
- Q: How to determine the maturity of coke or not?
- The degree of fragmentation of coke: refers to the different levels of coke accounted for the percentage of total coke production. The particle size of coke is very important in blast furnace smelting. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well.Breaking strength of metallurgical coke (M40 drum index)The breaking strength of metallurgical coke is an index to reflect the breaking resistance of coke.Wear resistance of metallurgical coke (M10 drum index)The wear resistance of metallurgical coke is an index to reflect the wear resistance of coke.
