Phosphorus iron honeycomb appearance, phosphorus is 20-26%, 0.1 6% of intergrowth compounds containing silicon. Phosphorus in the steel industry as an alloying agent, iron alloy additives for use in the metallurgical and deoxidizer.

In general steel products, phosphorus is harmful ingredients, but in some special products, the addition of phosphorus, can improve the performance of certain aspects of steel. Phosphorus iron is widely used in roll, auto cylinder liner, engine roller and large castings in order to increase mechanical parts corrosion resistance and abrasion resistance

Q: The difference between carbide knife and white steel knife: 1, two kinds of material composition is different: the former WC+Co+TiC, etc., the latter is generally C+Cr+W+Mo+v2, forming methods are generally different: hard alloy is powder metallurgy process (of course, some are powder metallurgy high speed steel)

Q: What kinds of carbide cutting tools are used in the 16 and 20 manganese grinding of the lathe?: Commonly used in 200*25*32 or 250*25*32 green carbide grinding wheel, hardness K or L, particle size 60.Cemented carbide: an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials. Now, the cutting speed of new carbide tools is several times that of carbon steel. Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.

Q: What are the grinding carbide wheels?: Diamond grinding wheel, carborundum wheel. Only welded blades use carborundum wheels, and generally fine grinding blades use diamond grinding wheels.

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: What does carbide K15-K20 refer to?: The smaller the value, the harder the hardness of the table is and the less resistant it is to the impact;

Q: Is carbide resistant to alkali?: Hard alloy chemical composition are general acid-base stability, it has no effect on, also has strong alkali resistant corrosion resistant hard alloy sintered hard alloy is added in different metal powders, can improve the hard alloy for corrosion resistance

Q: What is the coefficient of thermal expansion of cemented carbides?: [cemented carbide] an alloy material made from powder metallurgy by hard metals and bonded metals of refractory metals. Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness. Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.

Q: Carbide saw blades, plain and alternating teeth. What do you mean? That good?: Kunshan Feng rui1 tool company to provide technical information:The whole tooth tooth alternately around the turn, is used in the wood. The ladder tooth, generally used for cutting aluminum. So choose what kind of tooth shape is based on what cutting material to choose, and not good or bad points.How to choose the profile of alloy saw bladeThe tooth shape of a commonly used alloy saw blade tooth (alternate teeth), flat teeth, ladder flat teeth (low gear), trapezoidal teeth (inverted conical teeth), dovetail teeth (Tuo Fengchi), and industrial grade does not see more of the three left and right, left and right flat teeth etc.

Q: What are the carbide inserts on the turning tool welded to the handle?: The common oxygen welding and brazing flux borax and welding line! The welding method is as follows: when welding, first use four carbon chloride (CCl4) to wash the welding section of the knife pole, and then use the oxygen and acetylene to turn the tool red and then sprinkle borax! Melt the copper into the top of the knife. Place the blade on the knife and continue to burn until the copper and alloy blades come in contact. An ordinary soldering knife comes out.

Q: Do you want to center hole? How deep is fit? Or do not hit it directly? My drill bit and the center hole contact point are easy to collapse: Detailed analysis of the specific circumstances, the general drilling site is very smooth, you do not need to hit the center hole. If the borehole is uneven or drilled on the slope, a center hole is required. If the drill hole is first deflected and re corrected, a center hole is also required.
