Ulwazi oluSisiseko lweCarbide eCemented lwaziswa ngeNkcukacha

Uninzi lwabantu abaqhelekileyo abanako ukuqonda okukhethekileyo kwe-carbide enesamente.Njengomenzi we-carbide oyingcali, uChuangrui uya kukunika isingeniso kulwazi olusisiseko lwe-carbide enesamente namhlanje.

I-Carbide inegama elithi "amazinyo amashishini", kwaye uluhlu lwayo lwesicelo lubanzi kakhulu, kubandakanywa ubunjineli, oomatshini, iimoto, iinqanawa, i-optoelectronics, imikhosi kunye nezinye iindawo.Ukusetyenziswa kwe-tungsten kwishishini le-carbide ene-cemented lidlula isiqingatha se-tungsten iyonke yokusetyenziswa.Siza kukwazisa kwiinkalo zenkcazo yayo, iimpawu, ukuhlelwa kunye nokusetyenziswa.

1. Ingcaciso

I-carbide ene-cemented yi-alloy ene-tungsten carbide powder (WC) njengento ephambili yokuvelisa kunye ne-cobalt, i-nickel, i-molybdenum kunye nezinye izinyithi njenge-binder.I-Tungsten alloy yi-alloy ene-tungsten njengesigaba esinzima kunye nezinto zetsimbi ezifana ne-nickel, isinyithi kunye nobhedu njengesigaba sokubopha.

2. Iimpawu

1) Ubunzima obuphezulu (86～93HRA, ngokulingana no-69～81HRC).Ngaphantsi kwezinye iimeko, ukuphakama komxholo we-tungsten carbide kunye nokugqwesa iinkozo, bukhulu ubunzima be-alloy.

I-2) Ukumelana nokunxiba kakuhle.Ubomi besixhobo esiveliswa ngulo mbandela ngama-5 ukuya kwamaxesha angama-80 aphezulu kunokokusika kwensimbi ephezulu;ubomi besixhobo se-abrasive esiveliswa ngulo mbandela ngama-20 ukuya kuma-150 amaxesha aphakamileyo kunezixhobo zentsimbi.

3) Ukumelana nobushushu obugqwesileyo.Ubulukhuni bayo buhlala bungatshintshi kwi-500 °C, kwaye ukuqina kusephezulu kakhulu kwi-1000 °C.

I-4) Ikhono elinamandla lokuchasana nokubola.Kwiimeko eziqhelekileyo, ayifuni nge-hydrochloric acid kunye ne-sulfuric acid.

5) Ukuqina okuhle.Ukuqina kwayo kugqitywa yintsimbi ye-binder, kwaye ukuphakama kwesigaba se-binder, amandla amakhulu e-flexural.

6) Ubunzima obukhulu.Kunzima ukwenza izixhobo ezinemilo enzima kuba ukusika akunakwenzeka.

3. Ukuhlelwa

Ngokwezibophelelo ezahlukeneyo, i-carbide enesamente inokwahlulwa ibe ngamacandelo alandelayo:

I-1) I-alloys ye-Tungsten-cobalt: Amacandelo aphambili yi-tungsten carbide kunye ne-cobalt, engasetyenziselwa ukuvelisa izixhobo zokusika, i-molds kunye ne-geological and mineral products.

2) I-tungsten-titanium-cobalt alloys: amacandelo aphambili yi-tungsten carbide, i-titanium carbide kunye ne-cobalt.

3) I-Tungsten-titanium-tantalum (niobium) i-alloys: amacandelo aphambili yi-tungsten carbide, i-titanium carbide, i-tantalum carbide (okanye i-niobium carbide) kunye ne-cobalt.

Ngokwemilo eyahlukeneyo, isiseko sinokuhlulwa sibe ziindidi ezintathu: i-sphere, intonga kunye nepleyiti.Ubume beemveliso ezingekho mgangathweni zodwa kwaye zifuna ukwenziwa ngokwezifiso.Chuangrui Cemented Carbide .ibonelela ngereferensi yokukhetha ibakala lobungcali.
