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.

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: suitable for processing the whole alloy drilling, milling, reaming and other cutting tools. This alloy tungsten, cobalt content, how many of you?
- Just found the carbide under YK15, its cobalt content in 10%.According to its brand, YK15 should be used to process cast iron, so the main ingredient should be WC+Co.So its WC component should be in 89-90% (just for inference, for reference only)Based on the molar mass of WC, the mass fraction of the W content is deduced
- Q: I only know a few big, like Zhuzhou, Chun Bao, Xiamen tungsten diamond. Anything else? I'm looking for a tool cutter
- I heard that Zhuzhou is better, you say diamond coated knives? This is the tool of two different materials, diamond is not coated
- Q: What is hard alloy steel?
- Modern ultra hard alloys are produced by sintering of carbides of tungsten carbide and some other elements. It is the hard metal (tungsten, tantalum, titanium, molybdenum, etc.) carbide carbide particles, with one or several iron elements (cobalt, nickel or iron) powder mixed, pressed molding, and then made by sintering.
- Q: What material is that ultrafine cemented carbide?
- Comparison of high-end materials, suitable for high - quality products, are generally fine particles of products. Its hardness and strength are superior. So the price is relatively high
- Q: What is the difference between them?From hardness, abrasion resistance analysis!
- Artificial diamond is in high temperature (about 2000 DEG C) and high pressure (5 ~ 9GPa) and the metal catalyst under the condition of the graphite into diamond (PCD) tool. The tool of non-ferrous metals and non-metallic materials processing the alloy, ceramics, glass, wood, graphite and other best. With a cutting speed of up to 5000m/min PCD cutting tool Aluminum Alloy above. High speed steel alloy steel is a kind of complicated, containing tungsten, molybdenum, chromium, vanadium and cobalt carbide forming elements about alloy element.
- Q: What is the difference between the raw and recycled materials of cemented carbides? The more specific, the better
- Raw raw materials are raw materials, recycled materials have been used, and then recycled and re produced, raw materials than recycled materials used, and more pure materials.
- Q: What is the heat treatment process of cemented carbide?
- Responsible for this, you said, carbide heat treatment is deceptive theory, try to eliminate the gap, improve the purity of the fly.
- Q: Material properties of Cemented Carbides
- Metal carbides, especially B, B, IV V VI B metal carbide melting point is above 3273K, the TAC hafnium carbide, respectively 4160K and 4150K, is the highest point currently know material. Most of the carbide hardness large, their microhardness is higher than 1800kg mm2 (micro hardness is hardness says one way for hard alloy and hard compound, microhardness 1800kg mm2 is equivalent to a diamond a Mohs hardness of 9). Many carbides are difficult to break down at high temperatures, and their antioxidant power is stronger than their constituent metals. Titanium carbide has the best thermal stability in all carbides, and is a very important metal type carbide. However, in an oxidizing atmosphere, all carbides are readily oxidized at high temperatures, which can be said to be a major weakness of carbides. In addition to carbon atoms, nitrogen atoms and boron atoms can also enter the voids of the metal lattices and form interstitial solid solutions. They are similar to the gap carbide in that they can conduct electricity, heat conduction, high melting point, high hardness and great brittleness at the same time. The matrix of cemented carbide consists of two parts: one is a hardening phase, and the other is a bonding metal. Is the hardening phase transition metal carbides in the periodic table of elements, such as tungsten carbide, titanium carbide, tantalum carbide, their hardness is very high, the melting point of 2000 DEG C, and some even more than 4000 DEG C.
- Q: Customers ask whether cemented carbide can be used in the food industry! ~
- Used for processing food should not be possible, the composition of tungsten carbide.
- Q: What are hard alloys? Which ones are they? How often are they chosen?
- Cemented carbide is a hard particle of refractory metals (tungsten, tantalum, titanium, molybdenum, etc.) that is mixed with one or more iron elements (cobalt, nickel, or iron), pressed and molded, and then sintered. Types and properties of cemented carbides: (1) classification and grade of cemented carbides. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide (WC) and binder cobalt (Co). The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt. For example, YG8 is a tungsten cobalt carbide that represents an average WCo = 8% and the remainder is tungsten carbide. Tungsten carbide cobalt carbide is mainly composed of tungsten carbide, titanium carbide (TiC) and cobalt. The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide. For example, YT15 represents an average WTi = 15%, while the others are tungsten titanium cobalt carbide with tungsten carbide and cobalt content. The tungsten titanium tantalum (NB) hard alloy is the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.
