    B Is féidir a bheith ag súil go mbeidh íosrialú bóróin 0.0005 % ag na gráid a thaispeántar sa tábla seo leis an litir B, mar 50B40. AIs tríd an bpróiseas bunfhoirnéise-leictreachais a mhonaraítear na gráid a thaispeántar sa tábla seo le réimír E. Déantar na cinn eile go léir a mhonarú de ghnáth tríd an bpróiseas bunúsach-teallaigh oscailte ach féadfar iad a mhonarú tríd an bpróiseas bunfhoirnéise-leictreachais le coigeartuithe san fhosfar agus sa sulfair.

     

    cIs iad seo a leanas na teorainneacha fosfair maidir le sulfair do gach próiseas:

    Foirnéis bhunúsach leictreach 0.025 uas % Foirnéis leictreach aigéadach 0.050 uas %

    Teallach oscailte bunúsach 0.040 uas % teallach oscailte aigéadach 0.050 uas %

    D Léiríonn an t-íosmhéid agus an t-uasmhéid sulfair steels athshulfurized.

    EFéadfaidh an ceannaitheoir na huasmhéideanna seo a leanas a shonrú: copar, 0.30 %; alúmanam, 0.050 %; agus ocsaigin, 0.0015%.

    gné níos tábhachtaí, ansin ba chóir feadánra fuar-oibrithe a shonrú go dtí trastomhas taobh istigh agus tiús bhalla nó trastomhas lasmuigh agus trastomhas taobh istigh.
    Feadánra Meicniúil Garbh-Chompaite — Ní sháróidh an t-athrú ar thrastomhas lasmuigh agus tiús balla an lamháltas sa Tábla. Clúdaíonn an tábla lamháltais mar a chuirtear i bhfeidhm ar thrastomhas lasmuigh agus tiús bhalla agus baineann sé leis an méid sonraithe.
    Feadánra Meicniúla Thalmhaithe—Ní rachaidh athrú ar thrastomhas lasmuigh thar na lamháltais sa Tábla. De ghnáth déantar an táirge seo ó fheadán fuar-oibrithe.
    Faid - Cuirtear feadáin mheicniúla ar fáil go coitianta i muilinn, 5 troigh (1.5 m) agus os a chionn. Cuirtear faid gearrtha cinnte ar fáil nuair a shonraíonn an ceannaitheoir é. Taispeántar lamháltais faid i dTábla .

    Ceanglas Tástála

    Tástáil 1.Hardness
    Nuair is gá teorainneacha cruas, rachfar i gcomhairle leis an monaróir. Liostaítear cruasanna tipiciúla i dTábla . Nuair a shonraítear é, déanfar an tástáil cruas ar 1 % de na feadáin.

    Tástálacha 2.Tension
    Nuair is gá airíonna teanntachta, rachfar i gcomhairle leis an monaróir. Tá airíonna teanntachta tipiciúla do chuid de na gráid is coitianta agus na coinníollacha teirmeacha liostaithe sa tábla.

    Tástálacha 3.Nondestructive
    Tá cineálacha éagsúla tástálacha ultrasonaic nó leictreamaighnéadacha nondestructive ar fáil. Déanfar an tástáil a úsáidfear agus na teorainneacha iniúchta a bhunú le comhaontú an mhonaróra agus an cheannaitheora.

    Tástáil 4.Flaring
    Nuair a bhíonn ceanglais speisialta ann maidir le glaineacht cruach, déanfar na modhanna tástála agus na teorainneacha glactha a bhunú le comhaontú an mhonaróra agus an cheannaitheora.
