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: Tungsten carbide cutter white steel cutter carbide cutter is what is the difference?: They are hard and not afraid of annealing, but they are brittle. Also called tungsten titanium alloy. Hardness can range from HRB89 to 95, with characteristics that are difficult to wear.

Q: I only know a few big, like Zhuzhou, Chun Bao, Xiamen tungsten diamond. Anything else? I'm looking for a tool cutter: What kind of cutting tools do you have? I can give you some information first

Q: I'm going to sell carbide cutters. Which industry do you want to sell?: Don't know whether you go to Suzhou haokai steel metal material limited company to see through

Q: The existing 60*60 standard cast iron plate, above 3 hard alloy welding specifications, probably in the 30*30, in which the appropriate welding method, know the friends willing to enlighten ah, thanks in advance.Some friends have said the binder is a copper brazing, the basic can be settled. As far as I know, many methods such as welding, high frequency welding, oxygen welding, I want to find a kind of welding method. The key is to understand the trouble with us, surface and surface welding: Then an old welder re - welded it once, and it worked out just now. Probably the main point is water welding, the flame can not blow the time is too long, alloy hair red, you have to immediately with the matrix together, right, not only faster, more important still prevail. Because it's not good to come second times if you're not allowed

Q: Compare the advantages and disadvantages of high speed steel and cemented carbide: Hard alloy powder is: high hardness metal carbide to micron order, with cobalt, molybdenum, nickel and other binder, under high temperature and high pressure sintering temperature. The carbide content in hard alloy than high-speed steel, high hardness, good abrasion resistance (HRC75--80).Hard alloy red hardness can reach 800-1000 degrees.Carbide cutting speed is 4 - 7 times higher than that of high speed steel, and cutting efficiency is highThe disadvantage is that the bending strength is low, the impact toughness is poor, the brittleness is great, and the impact and vibration resistance are low

Q: What does carbide wet grinding mean?: Wet grinding of cemented carbide is an important process in the production process, and its efficiency has a direct bearing on the quality of cemented carbide products. The main factors affecting the wet grinding efficiency of cemented carbide are as follows:1. ball mill speedThe mixing and grinding of cemented carbide powder in a ball mill barrel is achieved by the motion of the ball when the ball mill rotates. The movement of the ball in the tube depends on the speed of the ball mill. If the speed is too fast, from the heart, the ball will be posted on the wall and rotate together, the ball in the same cylinder wall relative static state, which is equal to the elimination of the ball should play a role, if the speed is too low, only along the bottom of the cylinder sliding ball, small mixture of crushing and grinding effect.

Q: What materials are ZK20 cemented carbides processed?: ZK20 belongs to the K hard alloy blades can car many materials, such as: wrought iron steel low alloy cast iron high alloy cast iron ductile cast iron Aluminum Alloy hard plastic

Q: What is the relation between the number of teeth of carbide saw blades?: 4 saw blade body hardness, flatness, end jump requirements are also different. In addition, there are some requirements for the speed of the machine and the feeding speed of the wood. 6, to do the saw blade equipment precision also has the very big relations. 7 'chopping waist' is the most difficult thing to do right now. Another: alloy blade why open? Prevent saw blades; increase friction. For example: 3: multi tooth and Small Tooth cut wood saw blade, what's the difference? The number of teeth of the toothed, generally more number of teeth, more cutting edge in unit time, the cutting performance is better, but the cutting teeth with hard alloy saw blade number, the price is high, but the serrated teeth too close, chip quantity is small, easy to cause the blade fever; the other saw too much when the amount of feed, with improper words cut per tooth little friction will increase the cutting edge and the workpiece, the influence of blade service life. Usually, the pitch of teeth is 15-25mm, and the reasonable number of teeth should be selected according to the cutting material.

Q: What is the base material of carbide saw blade?: Base material of carbide saw blade1., 65Mn spring steel, good elasticity and plasticity, material economy, heat treatment, hardenability, and its heating temperature is low, easy to deformation, can be used for cutting requirements of the blade is not high.2. carbon tool steel with high carbon content, high thermal conductivity, but by 200 degrees -250 degrees Celsius temperature, its hardness and wear resistance decreased rapidly, heat treatment deformation, hardenability, tempering time is long, easy to crack. Manufacture economical materials for cutting tools, such as T8A, T10A, T12A and so on. 3. alloy tool steel, compared with carbon tool steel, has good heat resistance, good wear resistance, good treatment performance, heat-resistant deformation temperature of 300 degrees -400 degrees, suitable for manufacturing high-grade alloy circular saw blade.4. high speed tool steel has good hardenability, hardness and rigidity, less heat distortion, ultra high strength steel, thermoplastic stability, suitable for manufacturing high-grade ultra-thin saw blade.

Q: Customers ask whether cemented carbide can be used in the food industry! ~: The processing link is possible. Food segment will not be able to ah!
