Abanye abantu ababandakanyeka kwimisebenzi ethile (umzekelo, abaphengululi beengcali, abakhenkethi) bahlawule ingqalelo ngokukhethekileyo kwisixhobo esinjengomese. I-Steel, apho yenziwe khona, iyahluka kwiimveliso zayo, izinto ezongezelelweyo ezenza ukubunjwa kwayo, ubunzima. Ngoko ke, baninzi abanomdla kulo mbuzo: luhlobo luni lensimbi lungcono ngommese?
Iimpawu zensimbi zeekhiwane
Umgangatho weengxube uthinteke ngqo kwizinto ezilandelayo:
- Ubunzima besitye kwiimeseke . Inokuthi ibhekiswe kuye njengokuba ikhono lomlenze liyakwazi ukumelana nokukhutshwa okanye ukutshitshiswa, okuya kuba yinto enzima. Njengomthetho, amaqabunga ngamacu abe nobunzima be-HR- 40-60. Eyona nto inqwenelekayo ukukhetha ikrele eliya kuba nobunzima kwi-50-60 HRC.
- Amandla ensimbi - eli gama libonisa umda, ogqithiseleyo okhokelela ekuhambeni okanye ekutshatyalaliswa kwelasi. Ngokusekelwe kule ngcamango, iimpawu zommese, njengobuncwane kunye nobunzima, nazo ziyakunikwa. Inqaku leplastiki lingaxhomekeke ekutshintsheni, litshintshe indlela yalo, kodwa lingaqhekeki. Izinto ezibuthakathaka ziya kutshatyalaliswa kwanokutshatyalaliswa okuncane.
- Ugqoke ukuchasana kwensimbi . Kuyakwazi ukugcina umlo wesalathiso esibonakalayo ekubambisaneni. Ukuvala ukuchasana kuhambelana ngqo nobunzima bensimbi. Kuphakamileyo kunzima iqela.
Iyiphi insimbi engcono ukuthenga umsi?
I-Steel iqukethe insimbi kunye nekhabhoni, enokufumaneka kwizinga eliphezulu, eliphakathi okanye eliphantsi. Ukongezelela, ukubunjwa kwalo kunokuquka izinto ezongezelelweyo zeekhemikhali - ingaba i-chromium, i-molybdenum, i-vanadium, i-nickel, i-manganese, i-silicon.
Ukuze unqume ukuba yiyiphi enye ephambili yokuthenga umsi, kuyimfuneko ukuba ufunde iimpawu zayo.
Zininzi izitovu zenziwa kwintsimbi yasentwasahlobo. Inalo mpawu:
- ukulungelelanisa kakuhle;
- amandla;
- bunzima;
- ubukho bezinto ezinjalo zeekhemikhali ezifana ne-manganese, i-chromium, i-silicon, i-nickel.
Ukungalunganga kwezi zinto kubandakanya ukutyekela okuphezulu kokubola.
Izitshini ezisuka entsimbi yasentwasahlobo zingabizwa ngokuthi ziphela jikelele: phakathi kwazo zikhona iikhikhi, kunye nabakhenkethi kunye nomkhosi.
Eyona nto inqabileyo yenziwe ngetsimbi yokuqhafaza imimese. Ngokuqhelekileyo, loo blaza yomsila unomxholo, ukwenzela ukuveliswa kwesimbi esebenzileyo ye-carbon-carbon, kunye nentsimbi ephindwe kabini yensimbi eyahlukileyo.
Amanqanaba e-Steel ukuze amakhiwane
Izitampu zensimbi zensimbi zijoliswe ngokukodwa ngokubonakala kwe-chromium kuzo. Yongezwa ukwenzela ukwandisa ukuxhatshazwa kwe-alloy corrosion, i-knife ayixutywanga ngaphantsi. Kodwa ngelo xesha, i-chromium iyavela ekunciphiseni amandla ensimbi, ngoko yongezwa ngexabiso elithile.
Iimpawu eziqhelekileyo zensimbi zixhomekeke kuloluhlu oluneemeko ezilandelayo zibe ngamaqela amathathu:
- Iintambo zomtya, ezinokuchasana kakhulu nokuqhawuka, zikwahlukana nokuchasana nokunxiba - ziquka i-AUS6, 7Cr17MoV, 65x3, i-Sandvik 12C27.
- Amacwecwe ezenzile ezenziwe ngetsimbi, ezinokuxhathisa nokuqina okuphezulu - ezi ziimveliso ze-AUS8, 440B, 95x18, i-Sandvik 19C27, i-Sandvik 13C26.
- Iibhanti ezibonakaliswa ngokuchasene nokubola kunye neyona nto enkulu kunazo zonke iimimese zithinteka-zibandakanya i-steel grade 154CM / ATS-34, i-VG-10, i-AUS10, i-440C.
Emva kokuba ufunde iipropati ezizezodwa zensimbi ngemivese, unokuzikhethela okulungileyo kuwe.
