We export many kinds of coke, such as metallurgical coke (met coke) of 40-100 mm, theNUT coke of 20 to 50 mm, coke breeze of 3 to 6 mm, and so on. The main source isShanxi coking plant.

Deoxidizer. Removing the oxygen in molten steel in the process of steelmaking, some ferroalloy can removing the other impurities such as sulfur, nitrogen in steel.

Additive in alloy. According to the requirements of steel composition, adding alloying elements in the steel to improve the performance of the steel.

Inoculant. In front of the cast iron casting in molten iron, improve the crystallization of castings.

Reducing agent to the metal thermal reduction process in the production of other alloy and nonferrous metal reducing agent; Non-ferrous alloy alloy additive; Also a small amount of used in the chemical industry and other industries.

All steel, steel capital is a kind of ferroalloys, it also makes the iron alloy is the most widely used, dosage biggest alloy.

Also put some iron with high carbon content in high school textbooks and all the iron alloy is called ferroalloy.

Q: What brand of carbide is used in woodworking tools?: Cemented carbide YG8/ has good toughness and good wear resistance. It is mainly used in drawing dies for wire and rod processing. At the same time, it is also suitable for rough cast, non-ferrous metal and its alloy, non ferrous metal, uneven surface and intermittent cutting, rough car, fine plane, fine milling, general hole and deep hole drilling, reaming and making woodworking tools, etc..

Q: What does carbide wet grinding mean?: 3. shape of the grinding bodyThe grinding body can be spherical or cylindrical. Our country generally adopts the spherical shape, which is easy to roll because of its spherical shape and has high efficiency, and can make the most effective use of the surface of the grinding body, and the abrasion is even, and the manufacture is easy.4. ball material ratioBall to material ratio refers to the ball to material weight ratio, the ball to material ratio is greater, the ball and material contact area is greater, the grinding efficiency is higher.Experiments show that in a certain range, improve the ball material can not only improve the grinding efficiency ratio, change the performance of mixture, and can obtain the structure of hard alloy structure and good performance, but the ball ratio can not be too large.5. solid-liquid ratioThe solid-liquid ratio is the ratio of the weight of the mixture to the volume of the liquid medium. Usually expressed as a volume of liquid added to a kilogram of material. But the solid-liquid ratio of slurry is suitable, and the grinding efficiency has the best value!

Q: Hello, what's your company? What do you do with carbide? Thank you in advance: Pro, what do you mean by that question? We are the hard alloy recycling companies, focus on hard alloy recovery, Qingdao cemented carbide business network, with the recovery of hard alloy scrap, hard alloy die, tungsten steel scrap recycling

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 is hard alloy grinding?: Green silicon carbide grinding wheel, green silicon carbide hardness brittleness is higher than black silicon carbide, abrasive sharp, good thermal conductivity, suitable for grinding hard alloy, optical glass, ceramics and other hard brittle materialThe diamond grinding wheel than boron carbide, silicon carbide, corundum and other general grinding blade grain made of sharp corner, small abrasion, long service life, high productivity, good processing quality, but the price is expensive, it is suitable for the grinding of hard alloy, ceramic, semiconductor and other high hardness brittle hard material.

Q: What are the parameters of the wear resistance of cemented carbides in addition to their hardness?: The wear resistance of cemented carbide is related to the proportion of titanium carbide and cobalt carbide contained in it. It contains more titanium carbide, less cobalt content, higher hardness and better wear resistance. But brittleness also increases, easy to break the edge, so it is suitable for finishing.

Q: What is the hardness of YG8 cemented carbide?: YG8 is a tungsten cobalt type material.Good wear resistanceDensity / (g/cm3): 14.5-14.9Hardness (HRA): 89Flexural strength (sigma bb/MPa): 1500Impact toughness K/ (J/cm2): 2.5

Q: Is nickel base alloy hard alloy?: 2, YT--- tungsten cobalt titanium alloy products, applicable to coarse, carbon steel and alloy steel uneven section in interrupted cutting when the YT5 rough planing, semi finishing, discontinuous surface rough milling and drilling.

Q: Is the hard alloy the same as the cemented carbide?: Superhard alloy and cemented carbide are not the same ah.Personally, the alloy feels like a metal of high hardness; for this is not very familiar, there is no right to speak;But the main component of cemented carbide is WC+Co. And some have TIC.TaC. Equal carbide. Basically out of the metal range.So you say cemented carbide and hard metal are different.If it is replaced by superhard materials and cemented carbide to compare. The carbide can be cemented into the superhard material.These are personal views and can be discussed more

Q: What about cemented carbide produced in Zhuzhou? What brand is good?: Diamond brand still has a certain position, the 1 floor said that the fine carbide sales company, I pass there every day, but also put Alibaba lights in there
