I-scraper blade yenziwe ngani?

I-Wolfram carbide

I-Tungsten carbide iyinhlanganisela eyakhiwe ngama-50% e-tungsten nama-50% ekhabhoni. Kunezindlela eziningana ezisetshenziswayo ukwakha inhlanganisela, evame kakhulu ukusebenzisana kwe-metallic tungsten ne-carbon emazingeni okushisa asuka ku-1400 kuya ku-2000°C. degrees celcius.

Izinsimbi zejubane eliphezulu

Insimbi enesivinini esiphezulu (HSS) iyingxubevange ehlanganisa insimbi (insimbi nekhabhoni) nezinye izakhi ezifana ne-chromium, i-molybdenum, i-tungsten, i-vanadium noma i-cobalt. Ama-elementi ngaphandle kwensimbi angenza kufikela ku-20% wokwakheka kwe-HSS, kodwa ahlale edlula u-7%.

Ukwengeza lezi zakhi ensimbi akudali ngokwakho i-HSS, impahla kumele futhi iphathwe ngokushisa futhi ifutha.

Insimbi enesivinini esikhulu (HSS) iyakwazi ukusika izinto ngokushesha kunensimbi ephezulu yekhabhoni, yingakho igama elithi "isivinini esikhulu". Lokhu kungenxa yobulukhuni bayo obukhulu kanye nokumelana nokuhuzuka uma kuqhathaniswa nekhabhoni ephezulu nezinye izinsimbi zamathuluzi.

Kungani kusetshenziswa insimbi enesivinini esikhulu ne-carbide kuma-scraper blades?

I-scraper blade kumele yenziwe ngezinto eziqinile kunento ekhuhlayo ukuze isebenze. Izakhi ezengeziwe ze-alloying nezinqubo zokukhiqiza, ezifana nokwelashwa kokushisa okungaphansi kwensimbi yesivinini esikhulu, kuyinikeza ubulukhuni obudingekayo ekukhutsheni.

I-Carbide scrapers inzima kune-HSS. Lokhu kuzivumela ukuthi zisetshenziswe kuhlu olubanzi nakakhulu lwezinto.

Ama-scraper blades angabuyiseleki esikhundleni

Ama-scraper blades angabuyiseleki ahlala enziwe ngensimbi yesivinini esikhulu, njengoba izindleko zokwenza yonke i-blade ne-shaft ngaphandle kwe-carbide zizoba phezulu kakhulu.

Ngenkathi ama-scraper blades angenakushintshwa ayenziwe ngensimbi yesivinini esikhulu, ingxenye encane kuphela ekupheleni kwe-scraper iphathwa ngokushisa futhi iyathukuthela. Indawo ephathwa ukushisa kanye nendawo enomoya opholile ivamise ukuhluka ngombala kusukela kuwo wonke amanye ama-shaft.
