1. Structure of Metallurgical Coke of Nut coke of -5 to 15mm Description：
For the blast furnace operation to achieve better technical and economic indexes of metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the nature of the thermal state in the smelting process.
Foundry coke, generally require large granularity, low porosity, high fixed carbon and sulfur content is low;Chemical gasification with coke, lax to strength requirement, but it requires good reactivity, high ash melting point;Calcium carbide production with focal requirements to improve the fixed carbon content as much as possible.

5. FAQ
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: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 metallurgical coke and chemical coke
- The chemical composition of coke including fixed carbon, ash, sulfur, volatile matter and moisture. Except moisture, other ingredients in dry coke, is an important raw material of cupola smelting, casting of the components of specific inspection requirements.
- Q:Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
- 3, calcium carbide coke is conductive body and a heating body for electric arc furnace of coke in the production of calcium carbide. Calcium carbide with coke into the electric arc furnace, arc heat and heat resistance at high temperature (1800-2200 degrees Celsius) under the action of complex reaction and lime, calcium carbide formation in the molten state (carbide). The generation process of the following reaction type available:CaO+3C - CaC2+CO-46.52KLCalcium carbide with coke should have low ash, high reactivity and high resistivity and grain size. The secondary characteristics, but also try to remove the powder and reduce moisture. Its chemical composition and particle size should meet the following requirement: >84% <14% fixed carbon, ash, volatile <2.0%, sulfur
- Q:What is the use of coke
- The physical properties of the coke coke coke screening composition, physical properties including bulk density, coke coke coke true relative density, apparent relative density and porosity of coke, coke, coke, thermal conductivity and specific heat of coke thermal stress, ignition temperature of coke, coke, coke thermal expansion coefficient of shrinkage, resistivity and permeability of coke coke. The physical properties of coke are closely related to its mechanical strength, thermal strength and chemical properties at room temperature. Following the main physical properties of coke: true density is 1.8-1.95g/cm3 0.88-1.08g/ cm3; apparent density; porosity is 35-55%; bulk density is 400-500kg/ m3; the average heat capacity is 0.808kj/ (KGK) (100 C), 1.465kj/ (KGK) (1000 DEG C); the thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C); ignition temperature (air) is 450-650 DEG C; dry ash free calorific value is 30-32KJ/g;
- Q:Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you
- 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:Listen to a lot of people say that steel is now coke is not true?
- Steelmaking is definitely not coke, but now most of the very mature iron making technology needs coke, the future direction of development of iron is not used or less coke
- Q:How to distinguish the level of coke. What is metallurgical coke
- The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke "
- Q:How many degrees of coke ignition temperature can ignite coke
- Ignition temperature (450-650) in air;The main physical properties of coke are as follows:True density is 1.8-1.95g/cm3;Apparent density of 0.88-1.08g/ cm3;
- Q:What are the main uses of coke
- Main use of coke:1, is the most important coking products, more than 90% countries most coke used in blast furnace, blast furnace with coke instead of charcoal, laid the foundation for the large-scale modern blast, is an important milepost in the history of metallurgy.
- Q:With the number of 1 tons of steel smelting coke
- Because it can reduce energy consumption and reduce costs. So in the iron and steel enterprises coke rate decreased as the main goal of public relations, all the staff for the blast furnace coke rate reduction efforts. A few data in Liaoning, the average coke rate of Anshan and Benxi, Anshan Benxi is 330kg/t, is 360kg/t, that is to say a pig needs 330 360kg and coke production 2 saddle of the iron and steel enterprises. Shanghai Baosteel coke for the best in the country, can reach about 280kg/t. Is about 280kg per ton iron coke, the national leading level.
