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:Effect of coke powder ratio on the index
Quality index of cokeHigh temperature carbonization coke is the solid product, its main ingredient is carbon, the pore structure of spores (or pore porous) with crack and irregular crack. Have a direct impact on how much strength and crushing strength of coke, the index of crack usually (crack length per unit volume of coke in the index) to measure indicator. Pore structure is mainly used for measuring the porosity of spores (pore volume percentage of the total volume of coke) said that it affects the reactivity and strength of coke. The coke used for different purposes, the porosity index requirements change, but it usually requires 40 to 45% metallurgical coke porosity, casting requirements of 35 to 40%, the export of coke need to crack about 30%. coke with high and low levels of porosity, the use of coking coal has a direct relationship, such as gas refining is mainly coke, crack, high porosity, low strength; as in coking coal Break the coke refining base of small, low porosity and high strength. The strength of coke is usually the crushing strength and abrasion resistance of two indexes to represent the strength of coke can be broken. No cracks or defects and M40 values along the fault reference external shock resistance structure; wear strength of coke coke refers to the ability to form glass the surface resistance to foreign friction and no fragments or powder, expressed as the value of M10. The degree of M40 crack coke compressive strength affect the value, value of pore structure of coke impact wear resistance of M10 spores. The determination of M40 M10 and a lot of value, many German migon drum test our method.
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
The answer is: (I), (III);(2) under the condition of high temperature, calcium phosphate reacts with carbon and silica to produce calcium silicate, phosphorus and carbon monoxide. The reaction equation is Ca3 (PO4) 2+5C+3SiO2High temperature. 3CaSiO3+2P+5CO =, calcium silicate is silicate, so can produce cement, brick or building materials such as,
Q:Coke can be used to do what carbon black can be used to do?
Carbon black in plastics industry is the first use of carbon black pigment coloring, is cheap. Second carbon black in plastics industry use is to have good ultraviolet absorption effect, its application shows quite obvious protective effects in plastic. Third carbon black in plastics industry use is conductive.
Q:Coke and coal is one thing
Not the same thing.Coal is often said of coal, including bituminous coal, lignite, anthracite, etc.
Q:How much sulfur content of Coke will affect the casting process of nodular cast iron
The level of spheroidization is not enough. The final sulfur content of molten iron before the spheroidizing treatment is best at 0.03%
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:It was concluded that the following two facts: coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore
K, Ca, Na, C, Mg, Al is not able to use C, CO, H2 and so on to restore the preparation of metal, because these metals are very active, can be used to restore copper and iron ore, indicating that the reduction of strong;
Q:What kind of coke is needed for smelting special steel
3) skeleton: smelting process in blast furnace is gas rise and decline occurred in the opposite charge of movement and interaction, the core permeability is the key operation of blast furnace. In the upper column, gas flow distribution of coke layer; in the middle of the column material, the coke from the skeleton effect, support has been melting the iron ore, the normal gas rise; in the lower column, high temperature in the solid massive existing coke and has become liquid hot metal and slag mixed together, become loose skeleton gas rising and falling iron and slag.
Q:What is the difference between coking coal and coke
Therefore, coke is not coking coal, coking coal is one of the products after processing
Q:The difference between coke and coal
Coal is known as the black gold, the food industry, which is one of the main sources of energy used in the human world since eighteenth Century...
