The kinds and application of carbide tungsten steel materials
Time:2015/4/20 Viewed:539

Carbide (tungsten steel) material, has good wear resistance and flexural strength, can be used to make a variety of drills, car tools, printed circuit boards for tools, engine-specific tool, watches machining special tools, the overall legislation cutter, the whole reamer, chisel, etc., has good versatility for a variety of materials processing aluminum, cast iron, steel and other items. But also to make carbide punches, mandrels, top and perforation tool, according to customer requirements, roundness, high precision, accuracy up to ± 0.001mm,
    Tungsten steel products for its excellent performance to become quality for industrial production and processing. Tungsten steel material suitable for people with good toughness and wear resistance suitable phase, mainly for wire rod, bar the drawing processing module. Also suitable for cast iron, nonferrous metals and alloys and non-metallic materials, uneven surfaces and interrupted cutting of fine cars, fine planning, precision milling, general hole and deep hole drilling, retaining hole and making woodworking tool. Crude has good toughness and wear resistance suitable phase, mainly for wire, bar drawn mold processing, but also for cast iron, nonferrous metals and alloys and non-metallic materials, uneven surfaces and interrupted cutting cars, fine planing, precision milling, open like a hole and deep, reaming and production of woodworking tool.
    Tungsten steel (alloy) with high hardness, wear resistance, strength and toughness, heat resistance, corrosion resistance and a series of excellent performance, especially its high hardness and wear resistance, even at a temperature of 500 ℃ also remained unchanged, at 1000 ℃ still very high hardness. Carbide is widely used as a material, such as turning, milling, planer, drill, boring knives for cutting cast iron, nonferrous metals, plastics, chemical fiber, graphite, glass, stone and ordinary steel can also be used to cut resistance material difficult to process hot steel, stainless steel, high manganese steel, tool steel. New carbide cutting speeds hundreds of times equal to carbon steel.
    Tungsten steel sintering process:
1: Removal of pre-forming agent burn phase, the following changes take place in this phase of the sintered body: Removal forming agent, the initial firing as the temperature rises, forming agent gradually decompose or vaporize, excluded from the sintered body, at the same time , forming agent is more or less to the sintered body by carbon, carbon amount will vary with different types of molding agent, quantity and sintering process. Powder surface oxides are reduced, at the sintering temperature, hydrogen can restore cobalt and tungsten oxide, if in a vacuum to remove the molding and sintering agent, carbon and oxygen reaction is not strong. Contact stress between the powder particles gradually eliminated, bonding metal powder began to produce recovery and recrystallization, surface diffusion began, briquette strength increased.
2: solid-phase sintering stage (800 ℃ - eutectic temperature): The temperature in the liquid phase occurs before the next, except to continue the process of what happens on stage, the solid phase reaction and diffusion intensified, plastic flow enhancement, the sintered body significant contraction.
3: liquid phase sintering (eutectic temperature - sintering temperature): When the liquid-phase sintered body appeared after shrinking completed soon, followed by crystallization transition, form the basic organization and structure of the alloy.
4: cooling stage (sintering temperature - room temperature): in this phase, and the phase composition of the organization of tungsten steel with different cooling conditions to produce some change, can use this feature, tungsten steel heat treated to improve its physical Mechanical behavior.
    Tungsten steel products represent typical:
1, carbide (tungsten steel) material, has good wear resistance and flexural strength, can be used to make a variety of drills, car tools, printed circuit boards for tools, engine-specific tool, watches processing special tools, Overall mills, overall reamer, chisel, etc., has good versatility for a variety of materials processing aluminum, cast iron, steel and other items. But also to make carbide punches, mandrels, top and perforation tool, according to customer requirements, roundness, high precision, accuracy up to ± 0.001mm, tungsten steel rod, also used to make drill, PCB board micro drill, mold thimble, mold top electrode rod, gongs knife, shuttle textile industry, machine journal, machine axis, etc.
2, tungsten steel strips, used to make, woodworking tools, wear parts.
3, tungsten steel plate, used to produce high precision and high wear-resistant mold, Progressive mold, anti-theft plates, X-ray radiation plates, knives, shaped parts.
4, tungsten steel discs, used to make circular blade, such as: aluminum plate blade, cut the foot blades, tungsten steel cut foot blades, tungsten steel V-CUT blade, V-CUT knives, tungsten steel cutting blades, tungsten Corrugated steel blade, fiber cutting blade.
5, high-temperature tungsten steel material, used to make the ceramic sintering mold, carbide sintering mold.
  Zhuzhou Sanxin Co., Ltd. is committed to tungsten carbide production steel fittings, tungsten steel processing, tungsten steel cutting tools, tungsten steel mold, imported high-precision tungsten steel, tungsten steel material, abrasion is required mold hardware business. Vision, not the world a little. Our strength lies according to the different needs of each user, and to order the production of forms, the pursuit of particularity, high efficiency and long life shape, to provide users with a unique product.
