1. Structure of Metallurgical Coke of Coke Strength after Reactivity 65 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: Carbide cutters can work on materials of higher hardness
- YG3A, Y6A, Y726, etc. can be processed more than HRC60 hardness hardness of the material.
- Q: Carbon steel valves in Baidu LibraryThe temperature can reach 425 degrees, is not without welding carbide seal, who has no detailed material ah?,
- This 425 DEG C is the limit temperature of ASTM A216: -30 DEG C - +425 DEG CBut if the sealing surface of rice now is PTFE, it can be as high as +80 degrees centigrade. If the PTFE material is good, it can reach +150 centigradeTherefore, the body material is carbon steel, only that the valve body of the temperature range of this materialLook at the inside of the valve,For example, cryogenic carbon steel in LCB, ASTM, A325 can reach -46 degrees --+340 degrees centigradeHowever, if the sealing surface of your body is the sealing surface of plain carbon steel, the temperature range of this carbon steel valve is only the temperature range of the ordinary carbon steelIf you say that now is the carbon steel valves used in the sealing surface of the safety valve, you must need welding hard alloy (STL or D series, etc.) should have strong hardness of hard alloy after treatment, impact resistance.Depends on your flow channel medium, if it is high temperature, it is best to use 316, and so onThe use of valves is a combination of considerations
- Q: Carbide yk20? What do you mean?
- Cemented carbides YK20, Y represent alloy categories - tungsten cobalt, K20 represents cobalt contentDensity g/cm3:14.30-14.60;The hardness of HRA is more than or equal to 86.5;The shear strength is greater than or equal to N/mm2:2350,Performance and usage: with high toughness and wear resistance, suitable for embedding percussive rotary drilling bit, drilling in hard and tight hard rock.
- Q: I would like to solder a carbide tool now, what materials do you need to ask for specific methods?
- You need to use the Ya alloy electrode and welding tool first articles to be heated to red (a temperature of about 800~1000 degrees) and then stained with borax flux (in the electrode when need to add) and then work hard alloy or welded tungsten steel tools a turning tool on the lathe tool holder can be cut off in the car turning bracket that is the
- Q: Welding hard alloy cutter, hard alloy cutter, high speed steel, ceramic knife head head are what are the advantages and shortcomings?
- Advantages of carbide drills:1. can be used for drilling more complex materials, you can choose a higher cutting speed.2., selection of alloy drill special high-performance alloy blade, effectively reduce the avalanche knife, and maintain good wear resistance.3. multi layer geometry cutting end blade improves discharge performance and maintains smaller cutting resistance.4., in addition to the commonly used right angle stem, there are a variety of handle type, suitable for a variety of drilling machines, drilling machine matching.Disadvantages of carbide drills:The advantages of carbide drill can drill more hard material, the disadvantage is to be good grinding, grinding is not good, easy to break the edge, two main cutting edge height and angle equivalent, it is best to use the grinding machine.
- Q: What kind of cemented carbide is the most wearable?
- Carbide wear is due to the grain size and the cobalt content determines the finer granularity of cobalt content is lower, the higher hardness and lower hardness should be mentioned is the selection of wear-resistant hard alloy not only the hardness to see the use of general cutting hard alloy material with YW2 a relatively high hardness but if the working conditions impact operations more frequently if it should take into account its toughness but the toughness and hardness is conflicting under such circumstances can choose the class YG fine grain alloy
- Q: How to tell what is hard alloy and what is high speed steel?
- The same size, which is much heavier which is tungsten steel, is a small size parts, hard alloy than high speed steel felt component.
- Q: What is the heat treatment process of cemented carbide?
- To put it plainly, that is, hardening of cemented carbide, that is, heating to a certain temperature, insulation for a certain period of time, and then suddenly into the inert gas, so that it suddenly cooling.. The same as steel quenching. After quenching generally tempered, to eliminate the stress produced by quenching, it is mainly to change the bonding phase components, that is, the organizational structure, improve the strength of cemented carbide, hardness and comprehensive performance
- Q: The welding welding hard alloy cutter, should use what type of flame why
- With the fire on it. Put the knife and put some red hot and then put up with borax alloy outer flame burning red and then placed in a good point copper alloy and borax on the use of knife gap flow with upper and lower outer flame burnt gap can be
- Q: K carbide carbide cutting tools, mainly used for turning what materials?
- K class brand is the international standard ISO code, equivalent to China's class YG carbide brand, suitable for processing stainless steel, non-ferrous metals and alloys, as well as non-metallic materials, cast iron and other materials.
