Product Description:

1. Structure of Nut   Coke   with   Low   Phosphorous 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.

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
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.
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?
Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. In the steel-making pig iron sulfur content greater than 0.07% is waste. By blast furnace furnace into sulfur from 11% ore; 3.5% from limestone; 82.5% from coke, so coke is the main source of sulfur in charge coke. Sulfur directly affects the production of blast furnace coke. When the sulfur content 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 sulfur content of large and medium-sized metallurgical coke the blast furnace is less than 0.4 - 0.7%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the 0.02 - 0.03% or less
Q:The reaction of the blast furnace ironmaking is the reduction reaction: the coke produces CO in the furnace,
Thermal strength index: CSR CRIM40 M25 is the bigger the better, the smaller the better M10CSR the bigger the better the smaller the better CRISpecific standards to see the specific requirements of steel mills
Q:Braised meat burning coke, iron black layer, I do not know how to clean, please help answer
Shanlihong to paste potIf the bottom of the pot cooking, cooking paste, can put a few shanlihong put the pot, add a little cold water boil (not dry), paste pot bottom will soon get rid of.
Q:What is the amount of waste gas produced by a ton of coke burning
The coking coal is heated to 1000 DEG C under the condition of isolated air (high temperature carbonization)
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%
Q:What is coke? What is the use?
Lay the foundation for large-scale modern blast furnace, is an important milepost in the history of metallurgy. The blast furnace operation and achieve good technical and economic indexes, smelting with coke (coke) must have appropriate chemical and physical properties, including thermal properties in the smelting process.
Q:What is the phosphorus content in coke
Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
Q:Who knows what the provisions of the coke train sampling country?
Three, instrument and equipment of drying box: with automatic temperature adjusting device, can maintain the temperature of 170 DEG C and 105 a 180 a 110 C, the tray is made from galvanized sheet iron or aluminium sheet, size is about 300mm x 200mm X 20mm. The glass weighing bottles: diameter 40mm, high 25mm, and a grinding cover tightly. Dryer: inside the color of silica gel or granular anhydrous calcium chloride
Q:Effect of coke powder ratio on the index
Evaluation of coke quality1, coke: sulfur sulfur is a harmful impurity, pig iron smelting, which makes it one of the iron quality. In steel and iron sulfur content greater than 0.07%, is a waste. From the 11% blast furnace of sulfur ore; 3.5% limestone; 82.5% from coke, so coke is the main source of sulfur. The charge directly affects the coke into blast furnace of sulfur when the sulfur content of coke production. For more than 1.6%, 0.1% sulfur, each additional 1.8%, increase the amount of coke, an increase of 3.7%, ore blast volume added limestone to reduce the yield by 0.3%, sulfur content of 1.5 - 2% metallurgical coke requirements do not exceed 1% 0.7%., the sulfur content of metallurgical coke is less than - 0.4 large and medium sized blast furnace
