Coke Breeze with Size 3-6mm for Sinter plants
1. Structure of Coke Breeze with Size 3-6mm for Sinter plants 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: Standard grade two grade coke standard
- 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%.
- Q: How to calculate the average particle size of coke
- That is, "(volume) of the table of the percentage, in addition to the corresponding boundary value", these values are added, then the countdown. For example, the boundary 0 to 1 has a value of 10%, between 1 and 2, and between 2 and 4 has a value of 40%, and between 4 and 8, then D (3,2) = / (0.1/0.5 + 0.3/1.5 + 0.4/3 + 0.2/6) = 1/ (+ + 0.2 + + + 0.13 + +) = 1/0.56 = = =
- Q: Effect of coal fineness on coke
- The fineness of pulverized coal, which is less than 3mm of grain size, has a great influence on the quality of coke. The fineness of coal is one of the indexes of coal blending quality. In the production, when determining the fineness of coal, we should consider two aspects of the quality uniformity and production operation.
- 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: Who knows the proportion of pig iron and coke used in Cupola
- There are doubts: if the scrap ratio is too large to increase the difficulty of processing, product quality can not be guaranteed. The proportion is too high or too low are abnormal.2, auxiliary material input: foundry auxiliary materials mainly coke. Ordinary casting (except dry cylinder) 1 tons ~ ~ 5 tons cupola, each investment of 1 tons of coke, according to the situation of the piece can be from 4.5 tons to 5.5 tons. Ordinary blank (special pieces extra), 5 tons to 10 tons per 1 tons of coke in cupola furnace about 6.5 tons to 7.5 tons of blank (waste products re melted are calculated according to the above method).
- Q: Why is coke used in blast furnace steelmaking?Why not use coal?
- The reason of coke used in blast furnace steelmaking:Coke is the product after the desulfurization of coal, because the removal of sulfur in coal, coal tar and other harmful substances, no longer in the process of steelmaking, the impact on the quality of steel, the formation of unnecessary ingredients.
- Q: What is the use of coke
- Finally made coke, this process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis
- Q: Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- 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)
- Q: In the coke analysis index, M40% and M25% respectively mean what?
- M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%
- Q: What's the difference between coke and coke?
- In the process of coal carbonization of coal material: when the temperature is higher than 100 degrees in coal water evaporation; the temperature rises to 200 degrees above, combined with the release of water in coal; up to 350 DEG C, caking coal begin to soften, and further the formation of colloid viscous (this phenomenon does not occur, peat lignite; etc.) to 400 ~ 500 degrees most of the gas and tar precipitation, called a thermal decomposition products; at 450 to 550 DEG C, the thermal decomposition continues, gradually thickening and curing the formation of residue char!
