Product Description:

1. Structure of The  NUT  Coke  of  Size  is  10 – 30  mm 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:Why does casting coke require phosphorus?
As everyone knows, sulfur and phosphorus is harmful substances in the metal, because the sulfur is out in coke processing, so this index is not required, but the phosphorus in this process has not been effectively removed, so this is the requirement of foundry process or smelting plant. Phosphorus can reduce the strength of the metal, will lead to the metal "cold crisp", so to control the phosphorus content of coke, to prevent phosphorus into the metal.
Q:Relationship between coke M40 and M25
50 kilograms of size greater than 60 mm coke coke samples, in meters Qom in the drum at 50 rpm speed of 100 revolutions (4 minutes), with the aperture is 40 mm (25 mm) sieve screening, measuring more than 40 mm (25 mm) and the weight percentage of the coke, the total weight of the coke drum, denoted as M40 (or M25).
Q:Coking tower and coke tower is what relationship?
The question is not clear, according to the words you say should be: coking tower = coke towerThat will not help you
Q:Ca3 (PO4) 2, SiO2, coke and other raw materials for the production of silica gel (SiO2? NH2O), phosphorus, phosphoric acid and CH3OH, the comprehensive utilization of raw materials in the following process
The answer is: Ca3 (PO4) 2+5C+3SiO2High temperature. 3CaSiO3+2P+5CO =; production of cement, brick or building materials such as;(3) R Si, Si and HCl reaction is the reaction of SiHCl3 with hydrogen, by the reaction of the hydrolysis of SiHCl3, IV, and the generation of hydrogen and oxygen in a certain range will explode, so it must be in contact with oxygen and anhydrous conditions,Therefore, the answer is: SiHCl3 hydrolysis, while the production of H2, mixed with O2 explosion, etc.;(4) methanol oxidation reaction, under acidic conditions, methanol in the cathode of carbon dioxide and hydrogen ions, CH3OH+H2O-6e-=CO2+6H+,The answer is: CH3OH+H2O-6e-=CO2+6H+;(5) the significance of this link in industrial production: recycling of raw materials, energy saving and emission reduction,The answer is: recycling of raw materials, energy-saving emission reduction;(6) from P to H3PO4, the phosphorus and oxygen into water and phosphorus pentoxide, compound phosphate, the equation is P+O2=P2O5, P2O5+3H2O=2H3PO4,The answer is: P+O2=P2O5; P2O5+3H2O=2H3PO4
Q:What is the difference between the industrial analysis of coke and the industrial analysis of coal samples
Coke GB/T 1996-2003, volatile coke is the most difficult to do
Q:Coke is how to make it? What is the use?
Coke production has prepared the material into the coal charging car from coal tower, were sent to the furnace chamber. The gas produced by the dry distillation is sent to the chemical product recovery workshop for processing. After a coking period (from charging to pushing the required time is generally 14 to 18 hours, depending on the carbonization chamber and the width), a pusher will mature by refining coke coke machine into the coke car; coke quenching, coke is discharged into the cold coke; then screening and storage (Figure 4).The coking plant is generally composed of two coke ovens. The two coke ovens are arranged on the same central line, and a coal tower is arranged in the middle. A furnace with coke oven machinery -- corresponding charging car and coke machine, machine coke, coke quenching car and motor vehicle; also equipped with a set of facilities including coke quenching, coke quenching tower, coke quenching pump, coke powder and coke powder sedimentation tank grab, arranged in the end furnace group. The center of the coke quenching tower is not less than 40 meters from the center of the carbonization chamber. If dry coke quenching, coke oven station. The coking plant is also equipped with the necessary piping and reversing system.
Q:China's coke iron smelting began in what time?
The ancient iron smelting method in smelting iron block, lower temperature, iron ore solid reduction sponge iron, and iron into play by forging. Smelting iron block, furnace, furnace with ground and shaft 3. The block iron making in our country began in the spring and Autumn period, and in the near future, the pig iron with more than 2% carbon dioxide was refined and used as a casting tool
Q:How many degrees of coke ignition temperature can ignite coke
Ignition temperature (450-650) in air;Dry ash free base low calorific value is 30-32KJ/g;The specific surface area is 0.6-0.8m2/g
Q:How much coke oven gas is produced?
Each ton of refining coke can produce 430 cubic meters of gas, half melted combustion, the other half must be recovered with a special device, it can only be discharged directly into the air or "point sky lanterns
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
