Umehluko we-Hot-rolled kanye ne-Cold-drawn

I-hot-rolled isekelwe ku-slab (ikakhulukazi i-billet) njengento eluhlaza, eshisiswe umshini wokugaya kanye neqembu lokugaya elenziwe ngensimbi.Kusukela ekuqedeni okokugcina kumshini wokugaya oshisayo ngokupholisa i-laminar kuya kumazinga okushisa asethiwe, umshini wokugoqa ugoqa amakhoyili emicu yensimbi, umqulu wensimbi upholiswe ngokucubungula okuhlukile komugqa wokuqedela futhi ube yinsimbi, ivolumu eyisicaba kanye nemikhiqizo yensimbi yokusika.

Umdwebo obandayo usho izinga lokushisa elilingana negumbi, ngemva kokudweba okubandayo, ukugoba, ukudweba kanye nolunye ucwecwe olubandayo noma ukuhlubuka ekucubunguleni izinhlobo ezahlukene zensimbi.

Okushisayo futhiigoqekile umehluko:

I-1, inqubo yokwakhiwa kwensimbi edonsayo nebandayo edonsa insimbi noma ipuleti lensimbi iyafana, inomthelela omkhulu kusakhiwo esincane kanye nezakhiwo zensimbi, insimbi egoqiwe, insimbi egoqwe ngokushisa kakhulu esekelwe, esetshenziswa kuphela ukukhiqizwa kwensimbi. encane neshidi.

I-2, i-cold-form steel cross-section ibonakala ivumela ukubopha kwendawo, okungasebenzisa ngokugcwele umthamo wokuthwala induku ngemva kokubopha;kuyilapho insimbi egoqelwe ngokushisayo ingakuvumeli ukuhlangana kwe-cross-section of buckling yendawo kwenzeka.

I-3, Ngezizathu ezahlukene insimbi eshisayo egoqelwe kanye nokucindezeleka okusalayo kwensimbi ebandayo, ngakho-ke ukusatshalaliswa kwesigaba sesiphambano nakho kuhluke kakhulu.Ukusatshalaliswa kokucindezeleka okusalayo kwensimbi eyakhiwe ngendlela ebandayo esigabeni esiphambanayo kugobile, futhi ingxenye yensimbi egoqiwe eshisayo noma eshiselwe yokusabalalisa ingcindezi eyinsalela iwuhlobo lwefilimu.

4, Inkululeko yensimbi egoqelwe eshisayo egoqwe ngensimbi egoqelwe phezulu, ngakho-ke ukusebenza kwe-torsional kungcono kunensimbi egoqwe ebandayo egoqelwe.

5, Inqubo yokugoqa okushisayo: ishubhu - ukufudumeza - i-punch eshisayo - ukugoqa - umbhede wokupholisa, inqubo yokudweba ebandayo: ukuqala - izimbobo zokubhoboza - ukuqoqa - i-phosphate - ukudweba - ukudonsa.
