    Tohu Hua

    Ko ta matou kamupene e mahi ana i nga pakihi kaweake o te maitai waro me te rino koranu.Paipa Kohanga, paipa maitai koranu, Paipa maitai o Haina, paipa waro, Paipa Waro maitai, Paipa Waowao Haina.

    Kei te mohio koe ki te rereketanga i waenga i te rino waro me te rino koranu?

    waro maitai:Ko te nuinga e pa ana ki nga taonga miihini e whakawhirinaki ana ki te ihirangi waro o te maitai, me te nuinga o te waa kaore e taapiri i te maha o nga huānga whakakotahi o te maitai, i etahi wa ka kiia ko te waro waro maitai, te waro maitai ranei. Wao maitai, e mohiotia ana ano he waro maitai, waro ihirangi WC iti iho i te 2% rino waro koranu.

    Wao maitai i roto i te tua te tikanga kei roto i te nui iti o te silicon, konupora, whanariki, ūkuikui ka taea te wehea kia rite ki te whakamahi o te waro maitai waro hanganga maitai, waro taputapu maitai me te kore utu-tapahi maitai hanganga toru waro hanganga maitai kua wehea ki te maitai hanganga me te maitai o te hanganga miihini, ka taea te wehea ki te waro waro iti (WC ≤ 0.25%), te rino waro reo (WC 0.25% - 0.6%) me nga tira waro teitei (WC> 0.6%).

    E ai ki te ūkuikui me te whanariki, ka taea te wehewehe i nga tira waro ki nga tira waro noa (he teitei ake te ūkuikui me te whanariki), nga tira waro kounga teitei (he iti te ūkuikui me te whanariki) te maitai o te kounga teitei (te ūkuikui, te whanariki raro).

    Te rino koranu:i runga i te waro maitai, kotahi, neke atu ranei nga huānga whakaurunga ka honoa hei whakapai ake i te pai o te mahi me te mahi tukanga o te koranu i runga i te rino ka kiia ko te koranu maitai. Ko te rino Alloy e tohu ana ki te rino kei roto i te silicon me te manganese he mea whakakotahi, he huānga deoxidizing ranei, etahi atu mea whakauru penei i te chromium, nickel, molybdenum, vanadium, titanium, parahi, tungsten, konumohe, cobalt, niobium, zirconium me etahi atu mea, me etahi ano. kei roto etahi mea whakarewa-kore (penei i te boron, te hauota, me etahi atu) rino.

    E ai ki te nui o ngā huānga alloying i roto i te maitai, engari ano e taea te wehea ki iti koranu maitai, koranu reo me te maitai koranu tiketike.

    Rerekētanga hanganga matū:

    (1) Te maitai waro: Te waro waro iti (C≤0.25%); Wao maitai waro (C≤0.25 ~ 0.60%); Te maitai waro teitei (C≤0.60%).

    (2) Alloy steel: Iti koranu maitai (katoa ihirangi o ngā huānga alloying ≤ 5%); Waenga koranu maitai (katoa ihirangi o ngā huānga alloying> 5 ~ 10%); Te maitai koranu teitei (katoa te ihirangi o nga huānga whakakotahi> 10%.

    Nga painga o te rino waro:

    Ko te waro waro he kaha nui, he ngawari me te uaua, he iti te utu, ka whakamahia i roto i nga miihini taumaha mo te hanga i nga waahanga taumaha. Ka taea te whiwhi ma te maimoatanga wera pai ake nga taonga miihini maka.

    Ko nga painga o te Alloy Steel:

    I tua atu ki te rino i roto i te maitai huānga kei roto anake te waro maitai, waro maitai, te tahi atu silicon, whanariki, ūkuikui me ētahi atu poke. I tua atu i etahi atu mea o te chromium, manganese, molybdenum, titanium, tungsten, vanadium, niobium, boron, silicon me te nickel alloy steel ki te whakatutuki i nga taonga e hiahiatia ana penei i te teitei teitei, te teitei o te elasticity, te abrasion resistance, te kaha teitei, te uaua teitei me era atu. i runga. Ko te maaka o te rino te whakakakahu i te parenga, te pakari, te waikura pai atu i te waro maitai.

    I konei ka kite koe i etahi o nga mea e whakamahia anawaro maitaitohu rauemi i roto i te Tukatuka paipa.
