Product Description:


1. Structure of Metallurgical Coke of COKE BREEZE of 3 --6 MM Description:

The balance of supply and demand in general in a tighter supply, domestic demand for coke tighter supply dominant factor is no longer expanding, but by the shortage of transport capacity and resources remains tense double lead to supply shortages.But also want to see in the developed countries because of the economic crisis reduced demand for coke at the same time, the rapid growth of the economy in developing countries, will make up for the developed countries need to reduce the gap.

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.

On China's coke production distribution, the regional distribution imbalance of coking enterprises, mainly distributed in north China, east China and northeast China.

2. Main Features of the Metallurgical Coke of COKE BREEZE of 3 --6 MM:

• Quality assurance

Prices at the same time, in turn, will affect supply and demand, that is, when prices rise, the supply will increase and demand decrease, whereas will appear increasing demand and supply decrease, so the price and the mutual influence of supply and demand.

Q:What is the main purpose of the use of coke
(2) reducing agent.The reduction of ore in blast furnace is accomplished by indirect reduction and direct reduction. The indirect reduction is about 400 degrees centigrade. The indirect reduction is rising gas CO reduction in ore, iron oxide from high iron gradually reduced low iron until the metal iron, while producing CO2:
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:The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,
Coke strength index is divided into cold strength index and thermal strength indexCold strength index: M40 M25 M10
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 difference between coal and coke, heat, price, pollution, smoke, odor. Thank you experts answer
In terms of combustion, coal coke is a high pollution, therefore, coke pollution is less than coal. Coke smoke is very little, the smoke of coal is relatively large, there is also a high quality of soot rarely. When the coal is burning, the smell is bigger and the coke is not completely burnt, so the taste is small.
Q:How much coke is needed for a ton of iron
1 tons of iron: iron ore + + coke 340kg + pulverized coal injection 130kg,The process of extracting iron from iron containing minerals, mainly iron oxides, is mainly composed of blast furnace, direct reduction, smelting reduction and plasma method. From the perspective of ironmaking is metallurgy, iron rust, inverse behavior gradually mineralized, simple, pure iron reduction from iron compounds. Pure iron is not common in actual production. More iron carbon alloy.
Q:What are the requirements for coke and other accounts?
Futures account opening process1, customers need to carry the original natural person identity card or temporary identity card (must be within the validity period), at least any one settlement bank (China bank, agricultural bank, industrial and commercial bank, construction bank, Bank of Communications) debit card or passbook, to the Futures Company branch or the securities business Department (IB) personally.2, the signing of the "futures trading risk statement", "futures brokerage contract", "bank transfer", "letter of credit" and other agreements, to provide the phone, contact address and postal code.
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 is the reasonable standard of volatile content of coke
The sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%.
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.
