1. Structure of Metallurgical Coke of Coke Strength after Reactivity 64 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: What is the density of coke?
- There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.
- Q: What is the reasonable ratio of coal to coke
- According to the proportion of each unit type, different operation, different existing coal and different coke quality requirements are different and so on, can be said to suggest that the landlord can look at the altar of the myriads of changes, in some aspects of the coal blending, grasp some general principles, and then develop the proportion according to the actual situation.
- Q: After the long-term use of non stick pan, oil stains can not be effectively removed, over a long period of time in the non stick coating on the formation of a layer of coke, the effect of losing non stick. As a result of this layer of coke is relatively dense and smooth, scouring cloth has been ineffective, steel ball can not be used to damage the coating, what chemical or physical methods to remove this layer of coke?
- 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:
- Q: What is the difference between coke and carbon residue? Coke is a high-temperature refining, carbon residue can be used for civilian fuel it?
- Coke concept:Bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should Have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- Q: What are the requirements for coke and other accounts?
- 4, I personally set the password and password.5, the customer I own the bank transfer agreement, my ID card, bank debit card to the corresponding bank outlets for bank transfer procedures.6, the day of the day to accept the phone call Futures Company visit, after the successful return of T+1 days of commodity futures trading.7, the customer into the gold (silver period transfer; non bank transfer).8, customer online transactions (start trading).
- Q: Coke in the whole process of steelmaking in the end is what to do, just to provide heat or carbon and other substances into steel or iron?In the study of coal classification inside, one is divided into coking coal, coking coal and coke as main, and then you see is steel or iron coke must material. What is not clear. In the end, out of coal mining is mainly used to burn energy extraction, or said that coal like oil can be converted into other products, which is a coke can convert?
- 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 does the M40% and M25% mean in the analysis of coke?
- (1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.
- Q: What is coke and how is coke classified?
- Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed gas producer with solid slag, as the raw material to produce CO and H2 gas:C+O2 - CO2+408177KJCO2+C - 2CO-162142KJC+H2O - CO+H2-118628KJC+2H2O - CO2+2H2-75115KJBecause the process of producing the CO and H2 are endothermic reaction, need heat supplied by the coke combustion, so the heat is gasified char gasification process. The gasification coke required low ash content, high ash fusion point, block degree appropriate and uniform. The general requirements are as follows: >80% fixed carbon ash; 1250 degrees Celsius; volatile 84%, ash
- Q: What is coke? What is the use?
- The use of coke coke is mainly used in blast furnace and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, heating agent and columnar skeleton blast furnace adopts coke instead of charcoal.
- Q: What are the criteria for coke classification and how to distinguish between primary and two grade coke?
- The use of coke:Shanxi sales of various specifications of foundry coke, metallurgical coke, high sulfur coke or motor transport cars can be. The specific indicators are as follows:More than 83 of the fixed carbon; sulfur below the volatile content of less than 1.5; ash around 15 e:Mechanism coke: used in metallurgy; steel plantFiddle coke size 8cm-150cm: of molten iron for casting {;} of motor shell, radiator, mechanical counterweightCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweightLarge modified coke: {for ordinary casting; mechanical parts such as rough parts for 2-3.5 tons of furnace type}The shape of coke size 25cm:{is used for ordinary casting and slightly rigid casting products, such as water pump pipe fittings, such as fire fastenerMore than 85 of the fixed carbon; volatile 1.5.; ash content of less than 13.5 sulfur; less than 0.5:A fiddle coke size above 8cm for ordinary casting: {}Setting coke size 25cm; {for precision casting and ductile castingImproved coke: (Jiao Meilian) {for precision casting and ductile castingCoal tar: molten iron; used in the casting of motor shell, radiator, mechanical counterweight
