I-Spherical Cast Tungsten Carbide Powder

1. Yintoni iSpherical Cast Tungsten Carbide Powder?

I-Spherical cast tungsten carbide powder iqukethe amasuntswana amnyama angwevu, ayenziwe nge-ultra high-temperature spheroidization okanye inkqubo ye-atomization yegesi.

Ubume bekristale yeDendritic eyenziwe yiWC kunye ne-W2C: indawo yokunyibilika ephezulu (2525 ℃), ukuqina okuphezulu (HV0.1≥2700), ubume bentsiba ephezulu (umxholo≥90%), izinzile kwikhemikhali, ukuhamba kakuhle, ubuncinci obuphezulu, kunye nokumelana nokunxiba okuphezulu. .

Le mveliso isetyenziselwa i-diamond drill bit matrix materials, iplasma (PTA) imathiriyeli yokujonga phezulu, imathiriyeli yokutshiza, kunye ne-electrode enganyangekiyo kwi-carbide (ingcingo).

2. Ukuvelisa njani?

I-spherical tungsten carbide powder yenziwa ngokubanzi kumandla we-tungsten carbide eqhelekileyo okanye umxube we-tungsten (W), i-tungsten carbide (WC), kunye nekhabhoni (C). Kukho iinkqubo ezimbini zokuvelisa: (1) umxube we-tungsten powder oxutywe ne-tungsten carbide kunye ne-carbon powder inyibilika kuqala. Umxube onyibilikisiweyo wenziwa atomized ngokujikeleziswa kwe-atomizing okanye i-ultra-high-temperature yokunyibilika kunye nenkqubo ye-atomizing. I-spheroids ibe ngamasuntswana e-WC angqukuva ngexesha lenkqubo yokuqina ngokukhawuleza ngenxa yoxinzelelo lomphezulu. (2) Enye inkqubo isekelwe ekuguqulweni kwe-tungsten carbide powder rhoqo. Ukutshiza i-Plasma, ukufakwa kombane, okanye ukunyibilika kombane wokumelana nombane kusetyenziswa ngexesha lenkqubo ye-spheroidization ukufumana amasuntswana amahle e-WC.

3. Kuthekani ngokusebenza kwayo ngokwasemzimbeni?

Umxholo wekhabhoni olawulekayo;

Ubume be-W2C obufanayo kunye neWC enamanqanaba amabini;

Ubulukhuni obuncinci obuphezulu (HV0.1≥2700);

Ukucoceka okuphezulu (≥99.9%);

Ioksijini ephantsi (≤100ppm);

I-sphericity ephezulu (≥98%);

Umphezulu ogudileyo;

Akukho zibhola zesatellite;

Ukuhanjiswa kobungakanani besuntswana elifanayo;

Iimpawu ezihamba kakuhle (≤6.0s/50g);

Ubuninzi obukhulu (≥9.5g / cm3);

Ukuxinana kwempompo (≥10.5g/cm3).

I-cast spherical tungsten carbide powder ine-microstructure ye-equiaxed dendrites, njengoko kubonisiwe kwisithombe esingentla. Ifoto ye-SEM engezantsi ibonisa ngokucacileyo i-morphology yayo yamasuntswana ashinyeneyo angqukuva e-WC. Igcina iipropati ezizinzileyo zeekhemikhali, ukuguquguquka okulungileyo kunye nobunzima, kunye nokugqwesa ukunxiba / ukuxhathisa ukutshatyalaliswa. Ubungakanani bamasuntswana omgubo ophothiweyo we-WC otyhidiweyo busuka kwi-0.025 mm ukuya kwi-0.25 mm, ebonisa ukubengezela okungwevu okumnyama. Ubuninzi bayo obuthile yi-15.8 ~ 16.7 g / cm3 kunye nobunzima obuncinci ukusuka kwi-2700 ~ 3300 kg / mm2.

4. Ziziphi izicelo zayo?

I-cast spherical tungsten carbide powder isetyenziswa ngokubanzi kwi-hardfacing ye-drill bits kunye ne-PDC drill izixhobo, i-HVOF okanye i-PTA yokutshiza i-thermal kwindawo yezihlalo zevalve okanye iipaseji zangaphakathi, kunye nokwaleka kwe-weld kwindawo ejongene ne-flange, njl.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
