Ufa Wozungulira wa Tungsten Carbide

1. Kodi Spherical Cast Tungsten Carbide Powder ndi chiyani?

Spherical cast tungsten carbide powder imakhala ndi tinthu tating'ono takuda tomwe timapangidwa ndi ultra high-temperature spheroidization kapena gasi atomization process.

Dendritic crystal structure yopangidwa ndi WC ndi W2C: malo osungunuka kwambiri (2525 ℃), kuuma kwambiri (HV0.1≥2700), mawonekedwe a nthenga zazitali (zokhutira≥90%), zokhazikika pamakina, kuyenda bwino kwambiri, kulimba kwapang'onopang'ono, komanso kukana kuvala kwambiri. .

Izi zimagwiritsidwa ntchito ngati zida za diamondi zobowola pang'ono, zida za plasma (PTA), zowotcherera zopopera, ndi ma elekitirodi osamata a carbide (waya).

2. Zimapangidwa bwanji?

Ufa wozungulira wa tungsten carbide nthawi zambiri umapangidwa kuchokera kumagetsi okhazikika a tungsten carbide kapena osakaniza a tungsten (W), tungsten carbide (WC), ndi kaboni (C). Pali njira ziwiri zopangira: (1) kusakaniza kwa tungsten ufa wosakanikirana ndi tungsten carbide ndi carbon powder umasungunuka poyamba. Kusakaniza kosungunuka kumapangidwa ndi ma atomu ndi kuzungulira kwa atomizing kapena kopitilira muyeso-kutentha kwambiri kusungunuka & njira ya atomizing. Imasanduka tinthu tating'ono ting'onoting'ono ta WC panthawi yolimba kwambiri chifukwa cha zovuta zapamtunda. (2) Njira ina imachokera ku kusinthidwa kwa ufa wokhazikika wa tungsten carbide. Kupopera mbewu kwa plasma, kulowetsa magetsi, kapena kusungunuka kwa ng'anjo yamagetsi kumagwiritsidwa ntchito panthawi ya spheroidization kuti mupeze tinthu tating'ono tating'ono ta WC.

3. Nanga bwanji za thupi lake?

Kuwongolera kwathunthu mpweya wa carbon;

Uniform W2C ndi WC mawonekedwe a magawo awiri;

High microhardness (HV0.1≥2700);

Kuyera kwakukulu (≥99.9%);

Mpweya wochepa (≤100ppm);

Kukula kwakukulu (≥98%);

Malo osalala;

Palibe mipira ya satellite;

Kugawa kwa tinthu ting'onoting'ono;

Mayendedwe abwino kwambiri (≤6.0s/50g);

Kuchulukana kwakukulu (≥9.5g/cm3);

Kachulukidwe wapampopi (≥10.5g/cm3).

Mtundu wozungulira wa tungsten carbide ufa uli ndi mawonekedwe ang'onoang'ono a ma dendrites abwino, monga momwe tawonetsera pachithunzi pamwambapa. Chithunzi cha SEM chomwe chili pansipa chikuwonetsa bwino mawonekedwe ake a tinthu tating'ono tating'ono tating'ono ta WC. Imasunga zinthu zokhazikika zamakemikolo, kusinthasintha kwabwino komanso kuuma, komanso kukana kuvala / abrasion. Kukula kwa tinthu tating'onoting'ono tozungulira WC ufa kumachokera ku 0.025 mm mpaka 0.25 mm, komwe kumawonetsa kuwala kotuwa. Kachulukidwe ake enieni ndi 15.8 ~ 16.7 g/cm3 ndi micro-kuuma kuyambira 2700 ~ 3300 kg/mm2.

4. Kodi ntchito zake ndi zotani?

The cast spherical tungsten carbide powder amagwiritsidwa ntchito kwambiri pobowola ndi zida za PDC, HVOF kapena PTA mafuta opopera pamipando ya ma valve kapena ndime zamkati, ndi zokutira zowotcherera pa madera omwe akuyang'ana flange, ndi zina zambiri.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
