Ulwazi Oluyisisekelo Lwe-Cemented Carbide Yethulwa Ngemininingwane

Abaningi abavamile bangase bangabi nakho ukuqonda okukhethekile kwe-carbide enosimende.Njengomkhiqizi ochwepheshe we-carbide enosimende, uChuangrui uzokunikeza isingeniso solwazi oluyisisekelo lwe-carbide enosimende namuhla.

I-Carbide inedumela "lamazinyo ezimboni", futhi ububanzi bayo besicelo bubanzi kakhulu, kufaka phakathi ubunjiniyela, imishini, izimoto, imikhumbi, i-optoelectronics, amasosha kanye neminye imikhakha.Ukusetshenziswa kwe-tungsten embonini ye-carbide enosimende kudlula ingxenye yengqikithi yokusetshenziswa kwe-tungsten.Sizokwethula kusuka ezicini zencazelo yalo, izici, ukuhlukaniswa nokusetshenziswa.

1. Incazelo

I-carbide enosimende iyingxubevange ene-tungsten carbide powder (WC) njengento eyinhloko yokukhiqiza kanye ne-cobalt, i-nickel, i-molybdenum nezinye izinsimbi njenge-binder.Ingxubevange ye-Tungsten iyingxubevange ene-tungsten njengesigaba esiqinile kanye nezakhi zensimbi njenge-nickel, insimbi nethusi njengesigaba sokuhlanganisa.

2. Izici

1) Ukuqina okuphezulu (86～93HRA, okulingana no-69～81HRC).Ngaphansi kwezinye izimo, ukuphakama kokuqukethwe kwe-tungsten carbide kanye nokucoleka kwezinhlamvu, kukhulu ukuqina kwe-alloy.

2) Ukumelana okuhle kokugqoka.Impilo yethuluzi ekhiqizwa yile nto iphakeme izikhathi ezi-5 kuye kwezingama-80 kunezokusika insimbi ngesivinini esikhulu;impilo yethuluzi eliqhumayo elikhiqizwa yile nto liphakeme izikhathi ezingu-20 kuya kwezingu-150 kunamathuluzi ensimbi abrasive.

I-3) Ukumelana nokushisa okuhle kakhulu.Ubulukhuni bayo buhlala bungashintshile ku-500 °C, futhi ubulukhuni busephezulu kakhulu ku-1000 °C.

4) Ikhono eliqinile lokulwa nokugqwala.Ngaphansi kwezimo ezijwayelekile, ayiphenduli nge-hydrochloric acid ne-sulfuric acid.

5) Ukuqina okuhle.Ukuqina kwayo kunqunywa insimbi yokuhlanganisa, futhi lapho ukuphakama kwesigaba se-binder, kuyanda amandla okuguquguquka.

6) Ukuqina okukhulu.Kunzima ukwenza amathuluzi anezimo eziyinkimbinkimbi ngoba ukusika akunakwenzeka.

3. Ukwahlukanisa

Ngokusho kwama-binders ahlukene, i-carbide enosimende ingahlukaniswa ngezigaba ezilandelayo:

1) Ama-alloys e-Tungsten-cobalt: Izingxenye eziyinhloko yi-tungsten carbide ne-cobalt, engasetshenziswa ukukhiqiza amathuluzi okusika, isikhunta kanye nemikhiqizo ye-geological and mineral.

2) Ama-alloys e-Tungsten-titanium-cobalt: izakhi eziyinhloko yi-tungsten carbide, i-titanium carbide ne-cobalt.

3) Ama-alloys e-Tungsten-titanium-tantalum (niobium): izakhi eziyinhloko i-tungsten carbide, i-titanium carbide, i-tantalum carbide (noma i-niobium carbide) ne-cobalt.

Ngokwezimo ezihlukahlukene, isisekelo singahlukaniswa sibe izinhlobo ezintathu: i-sphere, induku kanye nepuleti.Umumo wemikhiqizo engajwayelekile uhlukile futhi udinga ukwenziwa ngokwezifiso.I-Chuangrui Cemented Carbide.inikeza ireferensi yokukhethwa kwebanga lochwepheshe.
