Product Description:

1. Structure of CRI   28%    Metallurgical   Coke  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. Separate focal piece of micro cracks along, namely coke porous body, also known as coke. Focal body consists of porosity and the pore wall, hole wall is also called the coke quality, its main component is carbon and minerals. How much coke crack directly affect the size and crushing strength of coke. Focal piece of micro cracks and holes spore structure of coke and abrasive resistance and high temperature reaction performance of coke has a close relationship. Spore structure usually use stomata average pore size and pore size distribution, specific surface area and pore wall thickness parameter.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

1) 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.

2) 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.

3) 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.

Q:How to determine the maturity of coke or not?
The sulfur content of coke: refers to the percentage of sulfur content in coke. Sulfur is one of the harmful impurities in pig iron smelting. The sulfur content in the pig iron is more than 0.07%. 82.5% of the sulfur from blast furnace charge into the furnace comes from coke, so coke is the main source of sulfur. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased by 3.7%, with the increasing of the amount of ore 0.3%, blast furnace production decreased 1.5 - 2%.
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:What's the difference between coke and coke?
When the dry distillation is carried out in the chamber type dry distillation furnace, the primary thermal decomposition product is contacted with the red hot coke and the high temperature furnace wall, and the two thermal decomposition occurs, and the thermal decomposition product (coke oven gas and other coking chemical products) is formed in the two timeThe solid product of low temperature distillation is a black semi coke with loose structure, low gas yield and high tar yield;The high temperature distillation solid product is the structure compact silver gray coke, the coal gas production rate is high and the tar production rate is low
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:With the number of 1 tons of steel smelting coke
The use of coke pig iron smelting blast furnace, for each different, which is each blast furnace coke ratio (the ratio of the iron smelting a ton of coke by iron determined how many meals). The country or the world, the iron and steel enterprises coke are not the same, the coke rate is as low as possible, but there are many factors which restrict the level of coke, such as advanced level equipment, raw material and fuel quality, or the operator level, advanced process and so on many factors which influence
Q:Relationship between coke M40 and M25
50 kilograms of size greater than 60 mm coke coke samples, in meters Qom in the drum at 50 rpm speed of 100 revolutions (4 minutes), with the aperture is 40 mm (25 mm) sieve screening, measuring more than 40 mm (25 mm) and the weight percentage of the coke, the total weight of the coke drum, denoted as M40 (or M25).
Q:How much coal can a kilogram of coal weigh?
The ratio is about 1 to about 0.7, that is, about 1 kilograms of coking coal can produce a total of about 0.7 kg of coke
Q:How to distinguish the level of coke. What is metallurgical coke
The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke "
Q:In the coke analysis index, M40% and M25% respectively mean what?
(2) mainly used in: Coal Science and Technology (first level), coal processing and utilization (level two), coal chemistry and coal quality analysis (level three)
Q:What are the indicators of first grade coke and the two grade coke?
The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)
