where is your company warehouse?
In Tianjin
- Q: What is the density of coke?
- Do you want to transport by rail? Ha ha, you might as well ask the freight forwarding clerk, he / she will tell you the various models of the volume and the weight can be installed, the conversion of the density of the pile is more accurate.
- Q: What is the difference between metallurgical coke and chemical coke
- Quality index of cokeCoke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). 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. 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.

- Q: How to remove the bottom of coke steel
- After high temperature sintering, and carbonization of things, glued to the pot, often with chemical methods.The most effective way to do this is by hand:Soak in hot water for a few hours (or a day and night).
- Q: What does the M40% and M25% mean in the analysis of coke?
- M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
- Q: Natural gas can replace coke smelting pig iron
- No, it's not just the temperature. It takes the chemical reaction of carbon and iron oxide to produce iron.Chemical equation: C+Fe 3O4 - Fe+CO2
- Q: What are the quality indicators of coke
- 2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%. 3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary. 4, volatile in coke: according to the volatile content of coke can determine the maturity of coke. Such as volatile content is greater than 1.5%, is said to produce coke; volatile less than 0.5 - 0.7%, it is said to be overdone, the general maturity of metallurgical coke volatile is divided into about 1%. 5, the moisture in the coke: water fluctuations will make the measurement of coke is not allowed, resulting in fluctuations in furnace conditions. In addition, the increase in the moisture content of Coke will make the M04 high, M10 is low, the drum index error. 6, the screening of coke composition: in the blast furnace coke particle size is also very important. In the past, the particle size of coke in our country is as follows: the coke size of large coke oven (1300 - 2000 square meters) is greater than 40 mm; the coke size of medium and small blast furnace is larger than 25 mm. However, some of the steel test shows that the coke particle size of 40 - 25 mm as well. Larger than 80 mm of coke to be whole, so that the particle size range. The coke block is uniform, the gap is large, the resistance is small, and the furnace condition runs well. Coke use: Shanxi sales all kinds of specifications of foundry coke, metallurgical coke, high sulfur coke trucks or wagons can transport
- Q: Effect of coke powder ratio on the index
- 6, the size of coke in the blast furnace, coke screening is very important. We used the coke size requirements: large oven coke particle size greater than 40mm (1300--2000 square meters); small blast furnace coke particle size greater than 25 mm. But experiments show that some steel mills, coke size 40--25 mm good. More than 80mm of coke are screened to little change in the size range. This fragmentation of the coke uniform gap, small resistance furnace is running well.Purpose: various specifications of Shanxi foundry coke, metallurgical coke, coke car or high sulfur transport cars online sales. The specific indicators are as follows:Fixed carbon 83 or above; sulfur less than 0.5; 1.5 or less volatile; ash about E:Focal mechanism:Violin coke size 8 cm -150 cm:Metabituminous:Bulk modified coke:Size of 25 cm:
- Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- 4, coke in volatile coke: according to the volatile content of coke can determine maturity. Such as volatile than 1.5%, said coke; volatile matter less than 0.5 - 0.7%, said too much, generally mature metallurgical coke volatile is about 1%.5, the moisture in the coke: water fluctuation will make coke measurement is not allowed, thus causing the furnace condition fluctuation. In addition, coke moisture will increase the M04 high, M10 low, to the drum index error6, coke screening composition: grain size of coke in blast furnace smelting. It is very important to China in the past, coke size requirements: on the coke oven (1300 - 2000 square meters) of coke particle size greater than 40 mm; medium and small blast furnace coke particle size greater than 25 mm. But some mills tests show that the coke 40 - 25 mm in size as well. More than 80 mm coke to whole, little change in its size range. So the coke size uniform, large gap, small resistance, the furnace is running well.
