Ferro Silicon is a ferroalloy an alloy of iron and silicon with between 15% and 90% silicon. It contains a high proportion of iron silicides. Its melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C. It also contains about 1% to 2% of calcium and aluminium.

Application: Ferro Silicon is usually used in steel industry as a deoxidizing material and it is also used as a bud or spraut in the Moulding industry. It also has major applications as deoxidizing material in steel manufacturing and alloy manufacturing industries, in the production of cast iron and steel, making improvement in the metallic structure and granulation in the molding of alloy and non-alloy cast irons, restoration of other Ferro alloys, and especially in the structure of nouvelle alloy steel.

Q:Method for assembling hard alloy cold heading die: Technological requirements for hole processing of cemented carbide die:1, carbide mold hole processing, selection, processing methods: according to the requirements of the drawings, select the electrical processing methods.2, select electrode material: according to the processing requirements, determine the processing methods and processing equipment to determine the electrode material.3. Design electrode: Design electrode according to clearance, shape and effective length of blade.4, processing electrode: generally use shaping grinding or square planer processing.5 、 clamping electrode.6, be processed carbide mold preparation.7. Calibration electrode.8 、 carbide mould clamping and positioning.9. Adjust the upper and lower positions of the spindle head.10, processing preparation.11, boot processing.12, regulation switching and intermediate inspection.13, carbide mold inspection: carbide mold after processing, should be carefully checked according to drawings, whether it meets the requirements of the drawings

Q:The milling of hard cutting workpiece hard alloy cutter knife edge collapse and Countermeasures of reason: Difficult to cut material hardness and strength are very high. The tool produces a great resistance to cutting, and the tool is difficult to resist such a large cutting force, so the tool will be damaged.There are solutions:Heat the treated material to reduce the hardness.Replace cutting tools with better machinability.Change the tool angle to resist greater cutting force.Reduce cutting parameters.Change the processing process, such as using EDM

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:Carbide coated drill bit will reduce the service life after grinding, how to avoid?: Sure, the grinding efficiency of the drill can reach about 80% of the new drill. Of course, the repair should be professional, experienced manufacturers repair oh. We can drill hard alloy coated drill bit to ensure quality.

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.Cemented carbide is the most powerful alloy in the world at present. Hard alloy widely used now has two main categories: the first is to do the cobalt WC alloy binder; the second is to make titanium carbide alloy tool steel binder.Cemented carbide is used as a tool, and its hardness will not decrease even at high temperatures of 1000 degrees. Therefore, for high speed cutting, cutting speed up to 2000 meters per minute, 100 times higher than the ordinary carbon steel cutter, tungsten steel cutter is 15 times higher than. The mold made of it can be punched about 3000000 times, which is 60 times longer than the ordinary alloy steel die.

Q:What are the meanings of cemented carbide codes, such as YW, YS30, YN10?Which company made its own brand? What is the composition?: Hard alloy is one of the people familiar with the tools and materials, it is very difficult to weld by hard metal carbides (we, Tie) of powder metallurgy with CO, MO and NI as sintering binder. Its mechanical, physical and mechanical properties depend mainly on the kinds of metal carbides, properties, quantities, grain sizes, types and components of binders.In cemented carbides, the proper addition of Tie increases the content of hard Tic, and the higher the hardness of the alloy. The more the content of cobalt in the bonding phase, the lower the hardness of the alloy. Therefore, the hardness of We-Tie-eo alloy is higher than that of We-eo alloy. The hardness of We-eo alloy can be increased by adding Tae or Nbc. The higher the hardness of the cemented carbide, the better the wear resistance, but the lower the strength (bending), and the addition of Tac will improve the blade strength, while strengthening the blade resistance to fragmentation and breakage, fatigue strength also increased. Generally, the higher the hardness, the lower the toughness. In China's Cemented Carbide standard YB850-75, most carbide grades are We-Co (YG) and We-Tie-Co (YT) two.Domestic hardness alloy grade control: GB, brand ISO, P10, P20, M10, M20, K01, K10, K20, K30, domestic uniform brand YT15, YT14, YT5, YW1, YW2, YG3, P30, YG6x, YG6, YG8

Q:What are the standard units of measurement for carbide inserts?: Manufacturers usually use KG, which is used inside the shop

Q:What are the differences between the two grades of carbide, YT15 and YT5?: YT15 is compared to YT5. The former has high hardness, great brittleness and good wear resistance. The latter is low in hardness, tough in toughness and poor in wear resistance.

Q:I would like to ask, carbide processing, cutting what cutting fluid is better, useful trouble recommended, thank you!: We are interested in many models, and finally found a cutting tool for carbide cutting fluid, MB132 extreme pressure microemulsion, in Dongguan. The cutting effect is satisfactory in the cutting fluid I tried.

Q:Make cutting dosage: But modern machining, has no strict distinction between the T and G class, but in different types of processed materials and processing conditions, different ways such as the use of different materials, and with appropriate coating, to reduce the cost requirements.Cutting parameters need to be selected according to different cutting occasions and different materials to be machined.
