Cineálacha
feadán cearnach dhosmálta,
Feadán cearnach ghalbhánuithe,
Feadán cearnach MS
Cóireáil dromchla:péinteáil beagán ola, péinteáil, galbhánú, sciath FBE
Feadán cearnach:Is feadán cruach éadrom le ballaí tanaí é feadán cearnach trasghearrtha cearnach log, is é sin, feadán cruach le taobhanna comhionann. Tá a struchtúr simplí agus cobhsaí, agus tá cumas ualachiompartha ard aige. De ghnáth cuirtear sonraíochtaí feadáin cearnacha in iúl i dtéarmaí fad taobh agus tiús bhalla.
Tá feadáin cearnacha roinnte ina seams gan uaim agus táthaithe. Déantar feadáin cearnacha gan uaim trí fheadáin bhabhta gan uaim bréifnithe agus easbhrúite. Déantar feadáin chearnógacha táthaithe a rolladh ó stiall-chruach trí chóireáil phróisis. Go ginearálta, déantar an stiall cruach a dhíphacáil, a leacú, a chuachta agus a tháthú chun feadán cruinn a dhéanamh. Rolltar an feadán cruinn isteach i bhfeadán cearnach ansin agus gearrtar é go dtí an fad is gá.
Aicmiú feadáin cearnacha:
Roinntear feadáin cearnacha de réir an phróisis táirgthe: feadáin cearnacha gan uaim te-rollta, feadáin cearnacha gan uaim fuar-tharraingthe, feadáin cearnacha gan uaim easbhrúite, agus feadáin cearnacha táthaithe.
Ina measc, roinntear feadáin cearnacha táthaithe i:
(a) De réir an phróisis - feadán cearnach táthú stua, feadán cearnach táthú friotaíochta (minicíocht ard, minicíocht íseal), feadán cearnach táthú gáis, feadán cearnach táthú foirnéise
(b) De réir seam táthú - feadán cearnach táthaithe seam díreach, feadán cearnach táthaithe bíseach
Roinntear feadáin cearnacha de réir cóireála dromchla: feadán cearnach ghalbhánuithe te-tumtha, feadán cearnach leictrea-ghalbhánuithe, feadán cearnach ola-brataithe, feadán cearnach picilte
Déantar feadáin cearnacha a rangú de réir úsáide: feadáin cearnacha le haghaidh maisiú, feadáin cearnacha le haghaidh uirlisí meaisín, feadáin cearnacha do thionscal innealra, feadáin cearnacha le haghaidh tionscal ceimiceach, feadáin cearnacha le haghaidh struchtúir chruach, feadáin cearnacha le haghaidh longthógála, feadáin cearnacha le haghaidh gluaisteán, feadáin cearnacha le haghaidh cruach bíomaí agus colúin , feadán cearnach sainchuspóra
Gnéithe feadán cearnach:
Ard-neart: Tá neart teanntachta, comhbhrúiteach agus lúbthachta ard ag feadáin cearnacha, is féidir leo ualaí agus brúnna móra a sheasamh, agus tá siad oiriúnach chun páirteanna struchtúracha éagsúla a tháirgeadh.
Cobhsaíocht mhaith: Tá cruinneas ard tríthoiseach ag an bhfeadán cearnach, struchtúr cobhsaí, agus níl sé éasca le dífhoirmiú, rud a d'fhéadfadh a chinntiú go bhfuil cruinneas ard agus cobhsaíocht ag na táirgí próiseáilte.
Friotaíocht creimeadh maith: Tar éis cóireála dromchla cosúil le galbhánú agus spraeáil plaisteach, tá friotaíocht maith creimeadh ag píopaí cearnacha agus is féidir leo oiriúnú do thimpeallachtaí casta éagsúla.
Costas íseal: Tá costas táirgthe feadán cearnach sách íseal agus éasca le próiseáil, rud a fhágann go bhfuil sé oiriúnach le haghaidh táirgeadh agus cur i bhfeidhm ar scála mór.
