Te tineia me te whakamahana o nga crankshafts
2020-01-16
Te tukanga tinei me te kaupapa
Ka whakamahanahia te mea mahi ki te pāmahana austenitizing mo etahi wa, ka whakamataohia i te reiti nui ake i te reiti whakamatao tino nui kia whiwhi i te tukanga maimoatanga wera o te hanganga martensite.
Ki te whakapai ake i te pakeke teitei me te mau atete o te mea mahi
Te tukanga whakamahana iti-mahana me te kaupapa
He tukanga maimoatanga wera e whakamahana ai te rino kua tineia ki te 250 ° C. ka whakamatao.
Kia mau tonu ai te pakeke me te whakakakahu i te parenga o te mea mahi kua tineia, whakaitihia te toenga o te ahotea me te pakaruhanga i te wa e tineia ana.
Me pehea te wehewehe i waenga i te crankshaft kua tineia me te kore tineia?
Ka tauhohe matū te rino me te hāora i roto i te rangi i te wera nui hei whakaputa i te rino trioxide pango. He rereke tenei ki ta tatou e kiia nei he waikura. Ko ta matou e kii ana mo te waikura ko te mahi a te rino ki te hāora, te wai, me etahi atu matū o te rangi i te pāmahana rūma ka hanga (te waahanga matua o te waikura) te waikura rino, whero.
Ka whakamahana te rino ki te hāora:
3Fe + 2O2 === Whakawera ==== Fe3O4
He waikura rino i te rangi:
crankshaft kore tineia
crankshaft kua tineia
