Umahluko phakathi kwe-Cemented Carbide kunye ne-High Speed ​​Steel (HSS)

I-carbide ene-cemented kunye ne-speed-speed steel ziyimveliso esezantsi ye-refractory metal tungsten (W), zombini zineepropati ezilungileyo ze-thermodynamic, kwaye zingasetyenziselwa ukwenza izixhobo zokusika, ukubumba okubandayo kunye ne-mold-working molds, njl. iintlobo ezahlukeneyo zezinto ezimbini, nazo ziyahluka ngokweempawu zoomatshini kunye nokusetyenziswa.

1. Ingcamango
I-carbide ene-cemented yi-alloy material eyenziwe nge-carbide ye-refractory metal efana ne-tungsten carbide (WC) powder kunye nentsimbi edibeneyo efana ne-cobalt powder. Igama lesiNgesi yiTungsten Carbide/Cemented Carbide. Umxholo wayo we-carbide ophezulu wobushushu uphezulu kunokuphakama kwentsimbi yesantya esiphezulu.

Isinyithi esinesantya esiphezulu siphezulu-carbon high-alloy steel eyenziwe sisixa esikhulu se-tungsten, i-molybdenum, i-chromium, i-cobalt, i-vanadium kunye nezinye izinto, ngokukodwa ezenziwe nge-carbides yensimbi (efana ne-tungsten carbide, i-molybdenum carbide okanye i-vanadium carbide) kunye i-matrix yensimbi, enomxholo wekhabhoni we-0.7% -1.65%, inani elipheleleyo i-alloying elements yi-10% -25%, kwaye igama lesiNgesi yi-High Speed ​​Steels (HSS).

2. Ukusebenza
Bobabini baneempawu zobunzima obuphezulu, amandla aphezulu, ukuqina okulungileyo, ukuqina okubomvu, ukuxhatshazwa kokugqoka, ukumelana nokushisa kunye nokusebenza kwenkqubo, kwaye ezi mpawu ziya kuba zihluke ngenxa yamabanga ahlukeneyo. Ngokuqhelekileyo, ubunzima, ubunzima obubomvu, ukuxhathisa ukunxiba kunye nokumelana nobushushu be-carbide enesamente kungcono kunezo zentsimbi yesantya esiphezulu.

3. Iteknoloji yokuvelisa
Inkqubo yokuvelisa i-carbide enesamente ibandakanya ngokukodwa inkqubo ye-metallurgy engumgubo, iteknoloji yokubumba i-injection okanye inkqubo yoshicilelo lwe-3D.

Iindlela zemveliso yentsimbi enesantya esiphezulu ziquka iteknoloji yokuphosa yemveli, itekhnoloji yokunyibilikisa i-electroslag, itekhnoloji yomgubo wesinyithi kunye neteknoloji yokubumba inaliti.

4. Sebenzisa
Nangona bobabini banokwenza iimela, ukubumba okutshisayo kunye nokusebenza okubandayo, ukusebenza kwabo kwahlukile. Isantya sokusika izixhobo eziqhelekileyo ze-carbide ziphindwe ngamaxesha angama-4-7 ngaphezu kwezixhobo eziqhelekileyo zentsimbi, kwaye ubomi benkonzo buphindwe ngama-5-80 ubude. Ngokumalunga nokubunjwa, ubomi benkonzo ye-carbide ene-cemented iyafa ngama-20 ukuya kuma-150 ngamaxesha aphezulu kunokuba i-high-speed steel dies. Ngokomzekelo, ubomi benkonzo ye-hot heading extrusion ifa eyenziwe ngentsimbi ye-3Cr2W8V ngamaxesha angama-5,000. Ukusetyenziswa kwe-extrusion yentloko eshushu ifa eyenziwe nge-YG20 ye-cemented carbide Ubomi benkonzo ngamaxesha angama-150,000.
