Tungsten Carbide VS HSS (1)

I-HSS (ifutshane kwintsimbi yesantya esiphezulu) yayiyinto eqhelekileyo yezixhobo zokusika isinyithi kwixesha elidlulileyo. Xa kwakusenziwa i-tungsten carbide, yayithathwa njengethathela indawo ngokuthe ngqo intsimbi enesantya esiphezulu enokuqina okuhle, ukumelana nokunxiba okugqwesileyo, kunye nobunzima obuphezulu kakhulu. I-carbide ene-cemented idla ngokuthelekiswa nentsimbi yesantya esiphezulu ngenxa yezicelo ezifanayo kunye nobunzima obuphezulu.

Ukusebenza kwe-tungsten carbide

I-tungsten carbide yi-micron-size metal carbide powder enzima ukuyinyibilika kwaye inobunzima obuphezulu. I-binder yenziwe kwi-cobalt, i-molybdenum, i-nickel, njl. I-tungsten carbide inomgangatho ophezulu we-carbide ephezulu kune-high-speed steel content. Ine-HRC 75-80 kunye nokumelana okugqwesileyo kokunxiba.

Izinto eziluncedo kwi-tungsten carbide

1. Ubunzima obubomvu be-tungsten carbide bunokufikelela kwi-800-1000 ° C.

2. Isantya sokusika i-carbide si-4 ukuya kwi-7 amaxesha ensimbi ephezulu. Ukusebenza kokusika kuphezulu.

3. Ubomi benkonzo yesikhunta, izixhobo zokulinganisa, kunye nezixhobo zokusika ezenziwe nge-tungsten carbide ngama-20 ukuya kuma-150 amaxesha ensimbi ye-alloy.

4. I-Carbide inokusika izinto ezinobunzima be-50 HRC.

Ukungalungi kwe-tungsten carbide

Inamandla okugoba aphantsi, ukuqina okulambathayo, ukuqina okuphezulu, kunye nokumelana nempembelelo ephantsi.

Ukusebenza kweHSS

I-HSS yintsimbi ephezulu ye-carbon high alloy, esisisixhobo esinobunzima obuphezulu, ukumelana nokunxiba okuphezulu, kunye nokumelana nobushushu obuphezulu. Kwimeko yokucima, i-iron, i-chromium, i-tungsten inxalenye, kunye nekhabhoni kwi-high-speed steel form form i-carbide enzima kakhulu, iphucula ukuxhatshazwa kwentsimbi. Enye inxenye ye-tungsten inyibilika kwi-matrix, inyusa ubulukhuni bentsimbi ukuya kuma-650°C.

Iinzuzo zeHSS

1. Ukuqina okulungileyo, ukuqina okugqwesileyo, ukusika okubukhali.

2. Umgangatho ohambelanayo, odla ngokusetyenziselwa ukwenza izixhobo ezincinci ezinokwakheka okuntsonkothileyo.

Ukungalungi kwe-HSS

Ubunzima, ubomi benkonzo kunye ne-HRC buphantsi kakhulu kune-tungsten carbide. Kwiqondo lokushisa eliphezulu le-600 ° C okanye ngaphezu kwe-600 ° C, ubunzima bensimbi yesantya esiphezulu buya kuncitshiswa kakhulu kwaye abunakusetyenziswa.
