Product Description:

1. Structure of NUT   Coke   of    20  ----  50  mm  Description

Coke is a hard texture, with carbon as the main component of irregular porous body, with cracks and defects in silver. The true density is 1.8 ~ 1.95 g/cm3, bulk density is 400 ~ 500 kg/m3, the porosity of 35% ~ 35%,.Coke all vertical and horizontal crack can be seen with the naked eye observation. The vertical and horizontal crack along the thick break, still is focal piece containing micro cracks.

Coke production of coking coal (coking coal), also known as metallurgical coal, belongs to the bituminous coal or sub-bituminous coal. Or use the various ratio of coal blend coking. Coking coal in the coke oven is isolated from oxygen after 1000 ° C carbonization is volatile component has been removing, the rest of the solid matter or coke. With the need of ironmaking as little as possible of sulphur, phosphorus pests, so should choose low sulfur, low phosphorus of coking coal.

5. FAQ

We have organized several common questions for our clients,may help you sincerely:

1) Main type

Metallurgical coke is blast furnace coke, coke, iron alloy and nonferrous metal smelting with coke. As more than 90% of the metallurgical coke for blast furnace ironmaking, so often called the blast furnace coke metallurgical coke.

Foundry coke is dedicated to cupola molten iron. Coke is the main fuel of cupola molten iron. Its role is hot metal melting furnace charge and overheating, support stock column maintain its good air permeability. As a result, coke blocks should have large, low reactivity, low porosity, with sufficient impact crushing strength, ash content and low sulfur content.

2) Application of coke

     Used for blast furnace ironmaking and used for copper, lead, zinc, titanium, antimony, mercury

     Other non-ferrous metal smelting of blast furnace,

     Reducing agent, compound

     The function of stock column frame.

3) The history of coke

From around the world, the coking coal resources are scarce, it is the precious resources must be protected, so has been seldom used coking coal coking alone. In China, the first kind of typical coal coking coal with hebei feng feng coal mine, shanxi gujiao cetrimonium, heilongjiang drops of jixi, anhui huaibei zhangzhuang and dabao top-coal panzhihua in sichuan province.The second category of typical coal coking coal have jilin tonghua iron works and the Inner Mongolia baotou beach ditch coal.Benxi, northeast China hebei tangshan, jingxing, shandong xinwen, etc., are all famous origin of coking coal.

Q:Coke in the steelmaking process in the end is what
It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnaceAfter the hot metal to steel in converter against the general converter, scrap also need to add a certain amount of used to balance the heat. Hot metal and scrap are added to the converter after the oxygen lance for oxygen operation, the oxidation of oxygen to carbon in liquid iron, silicon, manganese, phosphorus, sulfur and some non-metallic inclusions to form steel. Adding lime, dolomite, iron oxide and mine slag and coolant is needed in oxygen at the same time. After the completion of steel smelting in the tapping process according to different requirements with the corresponding iron alloy steel, after also refining process.
Q:What are the indicators of first grade coke and the two grade coke?
No greater than 12 is not greater than 0.6 not less than 80 not greater than 8 not greater than 1.9
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:The specifications for coke used in stainless steel smelting are as follows
Three metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6% "1%" water; sulfur;Maybe not, I'll give you a web site, find it yourself
Q:What are the criteria for coke classification and how to distinguish between primary and two grade coke?

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:What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you
6, the horizontal type coke oven drying machine(7) gas purification circulating water.... supporting technology(8) dry cooling technology of interlayer water-cooled steam.(9) microcomputer precise dosing system
Q:Is the power plant using coking coal or coke?
If most of the solid fuel is burning coal, but coking coal, which is very strong viscosity of coal is not good, it is very interesting to use the individual plant with it, the purpose is to change the fuel characteristics.Coking coal and coke, commonly used in metallurgical industry.Coal will be heated to a process of coke, but you really want to get coke, to specialized production. Power plants do not produce coke, they only have gray coke
Q:What is cokeWhat applications are, what is the fire of Malachite copper
Coke is used for heating, and coke is also used as a reducing agent to process the iron ore, the oxide ore, the malachite is the copper oxide
Q:I'd like to have a coke
Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage.
