Spherical Cast Tungsten Carbide Ifu

1. Ifu ya Spherical Cast Tungsten Carbide Ifu ni iki?

Ifu ya spherical cast tungsten karbide ifu igizwe nuduce duto twijimye twijimye, bikozwe na ultra-ubushyuhe bwo hejuru bwa spheroidisation cyangwa inzira ya gaze ya gaz.

Imiterere ya kirisiti ya Dendritic igizwe na WC na W2C: ahantu ho gushonga cyane (2525 ℃), ubukana bwinshi (HV0.1≥2700), amababa maremare （ibirimo ≥ 90%), imiti ihagaze neza, itemba neza, microhardness nyinshi, hamwe no kwihanganira kwambara cyane .

Iki gicuruzwa gikoreshwa mubikoresho bya peteroli ya diyama bit matrike, plasma (PTA) ibikoresho byo hejuru, ibikoresho byo gusudira, hamwe na sima ya karbide yangiza amashanyarazi (wire).

2. Nigute dushobora kubyara umusaruro?

Ifu ya karubide ya tungsten isanzwe ikorwa mububasha busanzwe bwa tungsten karbide cyangwa imvange ya tungsten (W), karbide ya tungsten (WC), na karubone (C). Hariho uburyo bubiri bwo gukora: (1) kuvanga ifu ya tungsten ivanze na karubide ya tungsten hamwe nifu ya karubone bishonga mbere. Uruvange rwashongeshejwe noneho ruterwa no kuzunguruka atomizing cyangwa ultra-high-ubushyuhe bwo gushonga & atomizing inzira. Isohora mu bice bya WC mu gihe cyo gukomera byihuse kubera ubushyuhe bwo hejuru. (2) Ubundi buryo bushingiye ku guhindura ifu ya karubide isanzwe ya tungsten. Gutera plasma, kwinjiza amashanyarazi, cyangwa gushonga amashanyarazi bikoreshwa mugihe cyo gukora spheroidisation kugirango ubone uduce twiza twa WC.

3. Tuvuge iki ku mikorere yumubiri yacyo?

Igenzurwa byose birimo karubone;

Imiterere ya W2C na WC ibyiciro bibiri;

Microhardness nyinshi (HV0.1≥2700);

Isuku ryinshi (≥99.9%);

Umwuka wa ogisijeni muke (≤100ppm);

Ubusumbane bukabije (≥98%);

Ubuso bworoshye;

Nta mipira ya satelite;

Ingano zingana zingana;

Ibintu byiza bitemba (≤6.0s / 50g);

Ubwinshi bwinshi (≥9.5g / cm3);

Kanda ubucucike (≥10.5g / cm3).

Ifu ya spherical tungsten karbide ifu ifite microstructure ya dendrite nziza ihwanye, nkuko bigaragara kumafoto yavuzwe haruguru. Ifoto ya SEM hepfo irerekana neza morphologie yayo yuzuye ya homogeneous spherical WC ibice. Igumana imiterere ihamye yimiti, guhinduka neza no gukomera, hamwe no kwihanganira kwambara / gukuramo. Ingano yubunini bwa poro ya WC ivuye kuri mm 0,025 kugeza kuri mm 0,25, ibyo bikaba byerekana ibara ryijimye. Ubucucike bwihariye ni 15.8 ~ 16.7 g / cm3 hamwe na micro-ubukana buri hagati ya 2700 ~ 3300 kg / mm2.

4. Ni ubuhe buryo bukoreshwa?

Ifu ya spherical tungsten karbide ifu ikoreshwa cyane mugukomeretsa bits hamwe nibikoresho bya drill ya PDC, HVOF cyangwa PTA spray yumuriro hejuru yintebe za valve cyangwa ibice byimbere, hamwe no gusudira hejuru kuri flange ireba ahantu, nibindi.

Niba ushimishijwe nibicuruzwa bya tungsten ukaba ushaka amakuru arambuye, urashobora kutwandikira ukoresheje terefone cyangwa amabaruwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
