1. Structure of Metallurgical Coke of Coke Strength after Reactivity 60 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's main physical properties are as follows:
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 ℃;
Low calorific value of dry ash-free basis for 30-32 kj/g;
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.

- Q:How to remove the bottom of coke steel
- Two, with cooking shovel (Mason's Pihui knife is best) to remove surface soft.Three, the same with a spade close to the bottom of the pot to eradicate. Until the last thing left is black.Four, wash the metal wire ball friction force discoloration, and always use water to clean out the dirt.
- Q:What are the requirements for coke and other accounts?
- 4, I personally set the password and password.5, the customer I own the bank transfer agreement, my ID card, bank debit card to the corresponding bank outlets for bank transfer procedures.6, the day of the day to accept the phone call Futures Company visit, after the successful return of T+1 days of commodity futures trading.7, the customer into the gold (silver period transfer; non bank transfer).8, customer online transactions (start trading).
- Q:Ask: coking coke tower tower and what is the relationship?If you can give a working principle to explain what is better!Coking tower in oil coking plant
- Coking plant coal tower, primary cooling tower, cooling tower, etc.. The coal tower is used to store coal for coke oven. The cooling tower is used to cool the gas and cooling tower cooling water.
- Q:The difference between coal and coke
- Today, the Customs Tariff Commission of the State Council issued the notice on the implementation of the tariff plan in 2013. Shang magnesium network noticed,. This important change, apparently stems from the WTO requires China to cancel the export of raw materials restriction policy decisions. In recent years, due to higher export tariffs, coke exports almost stagnant, but also indirectly affect the production of magnesium metal. Due to insufficient supply of coke oven gas, and the price increases, the production of primary magnesium in the main producing area of Shanxi magnesium metal has been seriously reduced. Shang magnesium network analysis, the abolition of coke and semi coke export tariffs next year, the amount of exports should be theoretically faster recovery, some of the original magnesium production capacity will be restored. However, the government may take other measures to limit coke and semi coke production, coupled with the western economic downturn, exports may be rapid growth. Therefore, the coke industry after the abolition of export tariffs on the market situation remains to be seen, the impact on the magnesium industry has yet to be further assessed.
- Q:Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you
- Foundry coke is used in cupola melting iron will fuel. Because the blast furnace cupola and metallurgical industry is different, only melting effect, without reduction reaction, the furnace is not so dephosphorization, the phosphorus in coke, some will come back to this in the metallurgical molten iron, called "Rephosphorized", this is decided by the principle of thermodynamics and kinetics. To make the original low phosphorus iron phosphorus increased harmful phosphorus. Therefore, the general foundry to buy Coke require low phosphorus coke. Some foundry with part of lime and dolomite in dephosphorization of iron in cupola, in the process, can relax the requirements for coke. However, this is suitable for large-scale, continuous production of iron.
- Q:Coke is divided into several kinds of specifications ah
- (Lord Jiao Meilian) {for precision casting and ductile casting for} fixed carbon above 86; sulfur ash is below 0.5; 12; 1.5: volatile fiddle coke grain size 4cm--8cm or above 10cm: fixed carbon furnace for {}} setting common casting coke particle size 25cm:{for precision casting and ductile casting for 3 more than 88 tons of sulfur ash; 0.5; 10; 1.5: volatile foundry coke particle size 25cm:{type applicable to the above all high precision ductile casting export and international index: {8cm} fiddle coke for common casting and casting products such as strict fire pump fittings; fasteners such as high fixed carbon above 788385} sulfur: {for copper, aluminum, plastic, chemical coke} fixed carbon above 83 gas coal coke: {for carbon monoxide gas extraction, rich gas} fixed carbon about 78 coal coke: {casting parts annealing, Coke, coke, civilian chemical copper, aluminum, plastic} fixed carbon about 65 coke, coke coal: {civil casting parts of annealing, chemical coke}
- Q:What is the reasonable standard of volatile content of coke
- Generally speaking, the volatile content of coke is about 1.5 or so, but not more than 2
- Q:What is the use of petroleum coke
- According to the quality can be divided into two kinds of primary and qualified products. Qualified products are divided into six grades. Used in the manufacture of electrodes, calcium carbide, corundum and so on and used as a filling tank, also used as insulating materials and fuel, etc..
- Q:What does the M40% and M25% mean in the analysis of coke?
- (1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.
- Q:What are the quality indicators 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. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test. Evaluation of the quality of coke, 1 of sulfur 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%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. 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 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%
