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.

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:Tungsten steel could be used to do is hard alloy knife?
Of course you can need what specifications of tungsten steel knife
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:Use of waste cemented carbide
Two, crushing methodFor hard alloy containing drilling is not high, because the hardness is relatively low, can use manual or mechanical means broken to a certain fineness in wet grinding mill for a period of time, to reach a certain size for reproduction of hard alloy. This force is a method has the advantages of simple process, short process, low energy consumption, no pollution to the environment, but often in the manual crushing hard alloy, metallic materials due to debris into the tools have broken material pollution, in addition, due to the hard alloy drill containing high amount of easily broken, mechanical crushing method is very limited; cemented carbide complex material by this method is also very difficult to ensure the quality of recycled products. Process method: artificial crushing is broken, crushed into powder 200 mesh or using bulk of hard alloy ball mill for crushing strikes the ball, then add in the bjm alcohol in wet grinding, and then enter the remanufacturing process of hard alloy.Some companies use cooling method: first crushing waste hard alloy in a muffle furnace heated to 80 above this immediately into the water quench, resulting in hard alloy cracking, and then enter the mechanical crushing process. This force is a method in the last century in 90s in Hebei Province Qinghe to gain popularity, there were dozens of county size ranging from recycling plant using the recycled and processed hard alloy, hard alloy processed over a thousand tons of annual production, the total output value of 300 million yuan, becoming one of the local pillar industry. At present, there is still a certain space for development of the crushing method, and the crushing method still needs to be improved by adopting more advanced and clean crushing equipment or by means of the force method which does not destroy the microstructure of cemented carbide with high efficiency.
Q:What's the use of recycling cemented carbide?
In the cutting tool is also hard alloy materials, recycling can be re - cemented carbide cutting tools ah.
Q:What is the heat treatment process of cemented carbide?
The common heat treatment process of steel bonded carbide is spheroidizing annealing, quenching and tempering.1, spheroidizing annealing die steel bonded carbide matrix is steel, as the alloy tool steel, need to be spheroidizing annealing treatment, can machine processing. The process of spheroidizing degradation is: heating 850~890 DEG C, holding 4h, and cooling the furnace to about 730 DEG C, holding 6h, the furnace is cold, and the air cooled below 500 degrees centigrade,2, the purpose is to make the quenching matrix transforms into martensite, obtain high mechanical properties, due to poor thermal conductivity, preheating, hard steel bonded carbide in carbide phase of austenite grain growth to deter, and the dissolution of carbide in the matrix alloy, iron and hinder the diffusion of carbon atoms, of austenite the grain growth plays an inhibitory effect, so the steel bonded hard alloy quenching overheating less than alloy tool steel, quenching temperature can be higher, the time may be longer, usually for WC type steel bonded hard alloy, quenching temperature of 1020~1050; for TiC type steel bonded hard alloy, quenching temperature is 950~1000 DEG C; G type steel bonded cemented carbide phase with high speed steel, quenching temperature of 1200~1280.3, steel bonded hard alloy die after quenching tempering should be timely, especially the large die should be timely, in order to eliminate quenching stress, prevent mold cracking, while tempering can adjust the organization to obtain the mechanical properties required, tempering temperature often take 180~200 C, 2h insulation, high toughness, high temperature tempering can be used as 500~650 C, but the need to avoid the brittle temperature zone at 250~350 DEG C, high temperature tempering, the carbide precipitation and residual austenite transformation, there will be two hardening, but high temperature tempering will cause precipitation of lead carbide link impact toughness decreases.
Q:Purchased welding wire, carbide grinding head, diverter, bolt, gear, etc.,
Bolts are standard partsDiverter and mutual inductor belong to instrument classGears and chains belong to mechanical partsTo have a task list of tasks, facilitate the cost accounting of this task.Establish simple running account, operator, operator's signature and use.
Q:Printing requirements for cemented carbide
Because of its superior properties such as high strength, hardness, excellent wear resistance and oxidation resistance, carbide is widely used in mechanical processing, petroleum mining, mold forming and structural wear-resistant parts and other fields. In the production of cemented carbide, sintering is the most important process. Even if the compacts are the same, different sintering processes have different effects on the properties of the sintered products. For a long time, many researchers have gradually formed a variety of sintering methods in actual production, including vacuum sintering, hot isostatic pressing sintering, vacuum follow-up hot isostatic pressing, sintering, hot isostatic pressing, etc..
Q:What is the difference between tungsten cobalt alloy and YG8 and YG6 series cemented carbide?
Commonly referred to as tungsten cobalt alloy is only YG class of cemented carbide, including YG3, YG3X, YG4C,
Q:The wood cutting tools are made of hard alloy, high speed steel and diamond.
Is the use of metal carbide hard alloy with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. Its hardness is 93 HRA8, high temperature resistance of 850 ~ 1000 C, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, hard alloy is commonly used tungsten cobalt (YG), tungsten titanium cobalt (YT) and general hard alloy (YW) three.Diamond is an allotrope of carbon, natural diamond and diamond two.
Q:Hard alloy and cast iron join together, what glue is good?
Carbide and cast iron are preferred welding methods. Instead of bonding.Can use oxygen acetylene flame gas welding (high combustion temperature, acetylene to hard alloy is heated to a suitable temperature, can be used instead of propane gas), first to the hard alloy is heated to (dark observation) small red, give heating. Were mixed with borax and boric acid as flux, HS201 copper wire dip brazing flux hard alloy and cast iron welding.Bonding shall be considered without welding conditions.The cast iron and carbide surface is polished with fine sandpaper. A soft cloth for wiping dirt and grinding residue. 1:1 AB glue evenly, smear on the contact surface of cast iron and hard alloy. Slightly pressurized. Set aside for 12 hours.
