Product Description:

1. Structure of Met   Coke   of    30  ----   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.

Coke production of coking coal (coking coal), also known as metallurgical coal, belongs to the bituminous coal or sub-bituminous coal. Or use the various ratio of coal blend coking. Coking coal in the coke oven is isolated from oxygen after 1000 ° C carbonization is volatile component has been removing, the rest of the solid matter or coke. With the need of ironmaking as little as possible of sulphur, phosphorus pests, so should choose low sulfur, low phosphorus of coking coal.

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

From around the world, the coking coal resources are scarce, it is the precious resources must be protected, so has been seldom used coking coal coking alone. In China, the first kind of typical coal coking coal with hebei feng feng coal mine, shanxi gujiao cetrimonium, heilongjiang drops of jixi, anhui huaibei zhangzhuang and dabao top-coal panzhihua in sichuan province.The second category of typical coal coking coal have jilin tonghua iron works and the Inner Mongolia baotou beach ditch coal.Benxi, northeast China hebei tangshan, jingxing, shandong xinwen, etc., are all famous origin of coking coal.

Q:Is the power plant using coking coal or coke?
If most of the solid fuel is burning coal, but coking coal, which is very strong viscosity of coal is not good, it is very interesting to use the individual plant with it, the purpose is to change the fuel characteristics.Coking coal and coke, commonly used in metallurgical industry.Coal will be heated to a process of coke, but you really want to get coke, to specialized production. Power plants do not produce coke, they only have gray coke
Q:What is the difference between coking plant and coke plant
Ha-ha,Coking plant, is a chemical industry, a variety of products,,Such as the production of coal tar, gas, coke and other chemical raw materials
Q:What is the reasonable ratio of coal to coke
According to the proportion of each unit type, different operation, different existing coal and different coke quality requirements are different and so on, can be said to suggest that the landlord can look at the altar of the myriads of changes, in some aspects of the coal blending, grasp some general principles, and then develop the proportion according to the actual situation.
Q:Why is coke used in blast furnace steelmaking?
The reason of coke used in blast furnace steelmaking:Coke is the product after the desulfurization of coal, because the removal of sulfur in coal, coal tar and other harmful substances, no longer in the process of steelmaking, the impact on the quality of steel, the formation of unnecessary ingredients.
Q:Mechanism of carbon and coke is not the same as the price which high?
Stick out almost all with crack. And they say the yield of 180 kg / hour also is very different, not only the normal production hours when the output of 100 kilograms. I had also directed his blog to the thought, the personality is good. It seems that I really fooled. Later on the Internet listen to friends that they and Beijing Shouke, and sell equipment are a group of Shouke and powerful equipment are factory Hebei Ba Chau do, the technician will not help garbage shit escape love who are also the factory to help Hebei Ba Chau cultivated. It is the general black crow. The wolf escaped, and ventured into the mouth. I put my story and I just hope I don't have the same people cheated, Juyuan suzerain is the biggest liar. Equipment market is too dirty, the bone charcoal mechanism shall not ah!
Q:What are the ingredients of coke
Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage. 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.
Q:China's coke iron smelting began in what time?
In the early period of the Warring States period, China has mastered the technology of decarbonization and heat treatment. The late Warring States period, but also invented a reusable "Iron Fan" (made of iron casting metal utensils of the hollow device). The Western Han Dynasty, appeared the crucible process. At the same time, the further expansion of the scale of shaft furnace. In 1975, in the vicinity of Zhengzhou guxing town discovered and unearthed Han iron smelting sites, site area of 120 thousand m2, two parallel excavated foundation of blast furnace, blast furnace volume of about 50m3
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: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:Purpose of using coke in iron making raw materials
Purpose as follows:1. Provide the heat required for the reaction2, do reducing agent, generate CO, at the same time itself can also restore the iron
