Abanye abantu abahlanganyela emisebenzini ethile (isibonelo, abapheki bezisebenzi, abavakashi) bakhokhela ngokukhethekile ukukhetha ithuluzi elinommese. Insimbi, okuvela kuwo, ihluke emikhiqizo yayo, izakhi ezengeziwe ezakha ukwakheka kwayo, ubunzima. Ngakho-ke, abaningi banesithakazelo kulo mbuzo: uhlobo luni lensimbi olungcono kummese?
Izimpawu zensimbi ngemimese
Ikhwalithi yemimese ihlaselwe ngqo yizici zayo ezilandelayo:
- Ubukhuni bensimbi emimese . Kungabhekiselwa ekutheni ikhono le-alloy liyakwazi ukumelana nokukhipha noma ukukhipha, okungahle kube yinto eyinkimbinkimbi. Njengomthetho, amajaji amakhela anobunzima buka-40-60 HRC. Kuyinto enhle kakhulu ukukhetha ummese oyoba nobunzima ebubanzi buka-50-60 HRC.
- Amandla ensimbi - leli gama libonisa umkhawulo, odlulele okuholela ekuthuthukiseni noma ngisho nasekubhujisweni kwekhasi. Ngokusekelwe kulo mqondo, izici zommese, njenge-ductility ne-brittleness, nazo zinqunywa. I-athikili yepulasitiki ingase ibe yinto enhle yokuguquguquka, ishintshe isimo sayo, kodwa ingaphuli. Izinto ezibuthakathaka zizobhujiswa ngisho ne-deformation encane.
- Gqoka ukumelana kwensimbi . Kuyinto ikhono lokugcina umumo wekhasi elivezwe ukuxubana. Ukugqoka ukumelana kuhlobene ngqo nobunzima bensimbi. Kuyinto ephakeme kakhulu ummese.
Iyiphi insimbi engcono ukuthenga ummese?
Insimbi iqukethe insimbi nekhabhoni, okungenzeka ibe nokuningi, okuphakathi noma okuphansi. Ngaphezu kwalokho, ukubunjwa kwalo kungabandakanya ezinye izakhi zamakhemikhali - kungaba i-chromium, i-molybdenum, i-vanadium, i-nickel, i-manganese, i-silicon.
Ukuze unqume ukuthi iyiphi engcono yokuthenga ummese, kubalulekile ukutadisha izici zayo.
Imivimbo eminingi yenziwe entwasahlobo yensimbi. Inezici:
- ukuguquguquka okuhle;
- amandla omthelela;
- ubulukhuni obuphezulu;
- ukutholakala kwezakhi ezinjalo zamakhemikhali ezengeziwe njenge-manganese, i-chromium, i-silicon, i-nickel.
Ukungahleleki kokuqukethwe kufaka ukuthambekela okuphezulu kokushisa.
Izitshalo zensimbi zentwasahlobo zingabizwa ngokuthi yi-universal: phakathi kwazo kukhona ikhishi, kanye nezivakashi , namabutho.
Okuthandwa kakhulu yi-steel laminated for imimese. Ngokuvamile, umshini onjalo wommese unomgogodla, ukukhiqizwa okusetshenziselwa ukukhishwa okukhulu kwe-carbon high-carbon, kanye nokubhekwa kwamaceleni amabili, okunye okunamandla kakhulu.
Amamaki ensimbi ngamabese
Izitembu zensimbi zensimbi zibhekene ikakhulukazi nokuba khona kwe-chromium kuzo. Yanezelwa ukuze kwandiswe ukumelana kwe-alloy corrosion, ummese awuncike kancane ekugqibeni. Kodwa ngesikhathi esifanayo, i-chromium iyingxenye ekunciphiseni amandla ensimbi, ngakho-ke ingeziwe ngamanani athile.
Imikhiqizo evamile kakhulu yensimbi ingaphansi kokuhlukaniswa okunemibandela elandelayo ngamaqembu amathathu:
- Ama-Blade blades, aphikisana kakhulu nokushisa, abuye abonakale ngokumelana okuhle kokugqoka - afaka i-AUS6, 7Cr17MoV, 65x3, i-Sandvik 12C27.
- Amakhela omsila enziwe ngensimbi, enokumelana nokuqina okuphezulu - lawa angama-brand AUS8, 440B, 95x18, Sandvik 19C27, Sandvik 13C26.
- Ama-Blades abhekene nokuphikisa okuhle ukubola futhi okukhulu kunazo zonke imimese ayigqoke ukugqoka - afaka u-grade 154CM / ATS-34, i-VG-10, i-AUS10, i-440C.
Njengoba usufunde izindawo zomuntu siqu zensimbi ngemimese, ungakhetha wena okungcono kakhulu kuwe.
