Product Description:

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 CSR64 % 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.

      We can offer below grade the NUT coke of 20 to 50 mm, origin from China.

Q:What is the main purpose of the use of coke
Direct reduction in the blast furnace in the area above 850 degrees celsius. Because the CO2 generated at high temperature immediately reacts with the carbon in coke to form CO, it can be considered that the carbon in coke is directly involved in the reduction process:CO is used as reducing agent, either indirect or direct reduction. In order to continue to add CO, requires a certain degree of reactivity of coke.
Q:Coke in the steelmaking process in the end is what
Coke is not used for blast furnace ironmakingThe use of blast furnace burden include iron ore (natural ore, sinter and pellets), solvent (limestone or dolomite), and coke, charge from top order batch into the furnace. Coke in the blast furnace ironmaking can be summarized as follows:(1) provide the heat: coke in the coke oven in front of the raceway in the intense combustion, combustion heat generated in the blast furnace smelting process is the main heat source(2) reduction: high temperature gas generated in coke combustion in the raceway, passed to the material in the process of heat rising, the endothermic reaction and coke formation, CO and H2, then CO and iron oxide in iron ore reduction reaction is transformed into metallic iron.
Q:Coke boiler belongs to coal-fired boiler
They produce coke boiler to clean fuel production to reduce emissions as the main content.
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:What kind of coke is used for steelmaking? The difference between metallurgical coke and foundry coke.
The following indexes: Metallurgical Coke metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur; two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile "1.9% full" water; 6%; "three sulfur 0.7%; metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6%" 1% "water; sulfur;
Q:The specifications for coke used in stainless steel smelting are as follows
Metallurgical coke indicators are as follows:A metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur;
Q:What does Coke test index M25 mean?
The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance
Q:Coke indicators are divided into grades
The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength
Q:What is the phosphorus content in coke
After drying, pyrolysis, melting, bonding, curing, shrinkage and other stages of the final coke, this process is called high temperature coking (high temperature carbonization)
Q:Types of coke and use of coke
The vertical furnace processing of low metamorphic coal production of calcium carbide, ferroalloy, coke, chemical fertilizer production and ultra high power electrode, aerospace and medical high technology and high value-added products such as carbon needle coke the world's most complete and unique characteristics of the Chinese coking industrial system.
