Product Description:

1. Structure of Metallurgical Coke of Coke lumps20-50MM 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. 

1/3 coking coal is a new coal, it is the high volatile, strong cohesiveness of a kind of bituminous coal, is between the transition between and among coking coal, fat coal, gas coal coal.Separate coking can generate molten sex good, high strength of the coke.Coke crushing strength generated close to fat coal coke, coke wear-resisting strength and significantly higher than the air fertilizer coke coal gas coal is generated.

5. FAQ

As a special and rare types of high-quality coking coal in Australia, the United States, Canada and other countries have been strategic protection, become strategic raw materials.As early as in 2009, the ministry of land and resources issued about the implementation of the national mineral resources planning, points out that strengthening the protection of important advantage of mineral and mining management, deal with the national economy is of important value of the special and rare types of coal which protective mining, reasonable control the scale of production, strengthen the rational use of coking coal, fat coal, etc.

Q:What is the main purpose of the use of coke
(3) column frame.The density of coke in blast furnace burden is the smallest, and the coke volume accounts for 35% ~ ~ ~ of the total volume of blast furnace burden. Coke is relatively strong, and in the tuyere area has always been to maintain the block, so it is the skeleton of the blast furnace column, from the loose material column, to ensure that the column has a good gas permeability of the role of the furnace is an important factor.
Q:Relationship between coke M40 and M25
Both are expressed in terms of the crushing strength of the cold mechanical strength index of coke quality.Among them, because of the specific measurement methods are not the same, so the use of different records.
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:Coke crushing equipment prices, manufacturers offer is how much
It is a solid product of high temperature carbonization, the main component of which is carbon, which is a kind of crack and irregular pore structure.
Q:China's coke iron smelting began in what time?
Han also invented the "fried steel law", that is, the use of pig iron "fried" mature iron or steel of the new process, the product is called steel. At the same time, the rise of "100 steelmaking" technology. The Eastern Han Dynasty (AD 25 ~ 220), when the emperor of the Ming Dynasty, invented the hydraulic blast furnace, that is, "water discharge". The invention of ancient water row in China, about 1100 years earlier than europe. After the Han Dynasty, the method of steel. "Qi Shu Qi, even referred to as" places "big steel", later known as the filling steel, also known as steel group. This is another important achievement of the ancient steelmaking technology in china. According to the "Encyclopedia of" records: Chinese is the earliest use of coal iron country, the Han Dynasty have been tried, song and Yuan dynasties have been popularized. To the Ming Dynasty (AD 1368 ~ 1644) has been able to use coke smelting pig iron.
Q:Why does Coke provide heat during ironmaking?
Yes;To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;
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 effect of coke moisture on the blast furnace?
The influence of coke moisture on blast furnace can be divided into two parts:
Q:What's the connection between coking coal and coke
Coking coal is divided into two categories, the first category of coking coal dry ash free volatile Vdaf>10% ~ 28%, G>65 bond index, thickness, y = 25mm. This part of the coking coal is particularly good, can separate the qualified blast furnace coke. Another kind of coking coal dry ash based volatile Vdaf>20% ~ 28%, caking index G>50 ~ 65, coking than the former difference. Coking coal is a kind of typical coking coal, which has a good thermal stability
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!
