1. Structure of Metallurgical Coke of Coke Strength after Reactivity 64 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: What is the sample quantity of coke moisture test? What is the test time? How many degrees? That is the national standard.
- Test procedureDetermination of total moistureA, said the samples size less than 13mm with pre dried and weighed for about 500g (referred to 1g), smooth specimen,B, a sample tray is placed on the 170 a 180 C in the drying box, LH removed after cooling, weighing 5min. C, check dryness, each time 10min, until the two consecutive quality difference in LG, calculate the quality of the last time.Determination of moisture content of samplesA, with the weighing bottle drying to constant quality in advance and has quickly called weighing samples size less than 0.2mm uniform mixing of the 1 + 0.05g (referred to 0.0002g), flat on the weighing bottle.B, will be filled with a sample of the bottle to be placed in the 105-110 drying box drying 1H, remove the weighing bottle immediately covered with lid, put into the dryer to cool to room temperature (about 20min), weighing.C, check of dry, insult 15min, until two consecutive poor quality in 0.001g, take the quality of the last calculation, if quality is weight gain first calculated on the basis of.Five, the calculation of test resultsCalculation of total moisture content according to formula (L):
- Q: Who knows the proportion of pig iron and coke used in Cupola
- Raw material inputs: the main raw material for casting pig iron, scrap steel, manganese, etc.. Under normal circumstances after the melting of ordinary cast iron scrap iron and scrap steel ratio of 9:1 or so, the drying enterprises use pig iron and scrap ratio of about 6:4, according to the requirements of the product. Because pig iron and scrap carbon content is not the same, the higher the carbon content of pig iron is about 4 ~ 4.3, low carbon steel scrap, about 0.8.
- Q: What kind of coke is needed for smelting special steel
- The role of coke in blast furnace ironmaking can be summarized as follows: 1:(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: Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
- If the paste pot may wish to try the following several waysBrush pot1, with hot water can be, it is easy to wash, do not use wire brush the ball, put the pot brush bad, if it is aluminum brush used for cooking after eating on the body is very good. (if you must brush it, you can use the cloth to replace the steel ball)
- Q: The chemical composition of coke m10.m25 refers to?
- M10 refers to the wear resistance of coke, M25 refers to the crushing strength is the mechanical strength. Mainly the cold strength of coke. Coke is also the most important indicator is the hot state, CRI thermal reaction and CSR reaction intensity. In blast furnace production, both cold and thermal strength are important.
- Q: The cost of iron ore and coke
- At present the general level of building materials enterprises, the price of 2400 yuan / ton steel
- Q: How long should it be to store coke in the open air
- The ground is flat, so it is convenient to transport.In addition, if it can be stored indoors, try not to open. For shelter.
- 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: Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
- 3, calcium carbide coke is conductive body and a heating body for electric arc furnace of coke in the production of calcium carbide. Calcium carbide with coke into the electric arc furnace, arc heat and heat resistance at high temperature (1800-2200 degrees Celsius) under the action of complex reaction and lime, calcium carbide formation in the molten state (carbide). The generation process of the following reaction type available:CaO+3C - CaC2+CO-46.52KLCalcium carbide with coke should have low ash, high reactivity and high resistivity and grain size. The secondary characteristics, but also try to remove the powder and reduce moisture. Its chemical composition and particle size should meet the following requirement: >84% <14% fixed carbon, ash, volatile <2.0%, sulfur
- Q: The two day of the fire is not wang you have a good way to have any good way. Such online
- Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage.
