Kodi Cast Tungsten Carbide Powder ndi chiyani

Cast tungsten carbide powder ili ndi mawonekedwe a WC ndi W2C eutectic omwe amawonetsa imvi yakuda. Cast tungsten carbide ufa amapangidwa ndi njira yapamwamba: tungsten zitsulo ndi tungsten carbide ufa amasakanizidwa ndikulongedza mu bwato la graphite. Pamodzi, iwo amatenthedwa mu ng'anjo yosungunuka pa 2900 ° C ndipo amasungidwa kwa nthawi inayake kuti apeze chipika choponyera chomwe chili ndi magawo a WC ndi W2C eutectic ndi kukula kwa tirigu wa 1 ~ 3 μm.

Imawonetsa mavalidwe apamwamba komanso kukana kwamphamvu, komanso katundu wowuma kwambiri, pakutentha kwambiri. Makulidwe a tungsten carbide tinthu timayambira 0.038 mm mpaka 2.362 mm. Kuuma: 93.0 ~ 93.7 HRA; yaying'ono-kuuma: 2500 ~ 3000 makilogalamu / mm2; kachulukidwe: 16.5 g/cm3; malo osungunuka: 2525°C.

Kuchita kwakuthupi kwa cast tungsten carbide powder

Kulemera kwa Molar: 195.86 g/mo

Kachulukidwe: 16-17 g/cm3

Malo osungunuka: 2700-2880 ° C

Malo otentha: 6000°C

Kuuma: 93-93.7 HRA

Kugwiritsa ntchito ma cast tungsten carbide grits

1. Valani zigawo za pamwamba (zosavala) ndi zokutira. Zigawo ndi zokutira zomwe zimavutitsidwa, abrasion, cavitation, ndi kukokoloka kwa tinthu monga zida zodulira, zida zogaya, zida zaulimi, ndi zokutira zolimba.

2. Diamondi Chida Matrix. Mafuta athu okonzeka kulowa kapena otentha-press cast tungsten carbide ufa amagwiritsidwa ntchito ngati matrix ufa kuti agwire ndikuthandizira chida chodulira diamondi. Wogwirizira amalola kuti diamondi iwonetsedwe bwino kwambiri kuti igwire bwino ntchito.

Kupanga Njira zopangira ufa wa tungsten carbide

1. Njira Yothirira Utsi. Magetsi oponyedwa a tungsten carbide amatha kupopera mafuta kuti apange zokutira zolimba pamawonekedwe ofunikira kuti asavale.

2. Kulowetsa. Cast tungsten carbide, coarse tungsten metal, kapena tungsten carbide powders amalowetsedwa ndi chitsulo chamadzimadzi (monga aloyi yopangidwa ndi mkuwa, bronze) kuti apange gawolo. Mafuta athu opangidwa ndi tungsten carbide ali ndi mwayi wolowera komanso mawonekedwe amavalidwe omwe amalola makasitomala athu kusintha njira yopikisana kuti awonjezere moyo wautumiki komanso kusinthasintha kwa mapangidwe.

3. Ufa Metallurgical (P/M). Mafuta a cast tungsten carbide amakanikizidwa m'zigawo zingapo kudzera mu kukanikiza kotentha ndi sintering.

4. Kuwotchera kwa Plasma Transferred Arc (PTA). Chifukwa cha kuwotcherera kwambiri kwa ufa wa tungsten carbide ufa, umagwiritsidwa ntchito pazinthu zambiri kudzera pa kuwotcherera kwa PTA.

5. Dip zokutira. Zovala monga zomwe zimapezeka mu maelekitirodi, zida zobowola, ndi zida zomwe zimagwiritsidwa ntchito popanga media abrasive zimakutidwa ndi cast tungsten carbide zomwe zimapereka kutha kwa pamwamba ndikulimba kwambiri komanso kukana kuvala.
