Isishwankathelo seCold Rolled Steel Coil

I-coil eqengqelekayo ebandayo yenziwe nge-hot rolled coil. Kwinkqubo eqengqelekayo ebandayo, i-hot rolled coil iqengqeleka ngaphantsi kobushushu bokuphinda i-recrystallization, kwaye intsimbi eqengqelekayo ngokubanzi iqengqeleka kubushushu begumbi. Ishidi lentsimbi elinomxholo we-silicon ophezulu linokubuthathaka okuphantsi kunye ne-plasticity ephantsi, kwaye kufuneka lifudunyezwe ukuya kuma-200 °C ngaphambi kokuba liqengqeleke ngokubandayo. Ekubeni i-coil eqengqelekayo ebandayo ingafudunyezwa ngexesha lenkqubo yemveliso, akukho ziphene ezifana ne-pitting kunye ne-iron oxide ezihlala zifumaneka kwi-hot rolling, kwaye umgangatho womphezulu kunye nokugqitywa kulungile.

Ibanga leKhoyili eqengqekileyo ebandayo

1. Uphawu lwaseTshayina uNombolo Q195, Q215, Q235, Q275——Q—ikhowudi yenqaku le-yield (umda) wentsimbi eqhelekileyo yesakhiwo sekhabhoni, efana ne-alfabhethi yokuqala yefonetiki yaseTshayina ethi "Qu"; 195, 215, 235, 255, 275 - ngokulandelelana imele ixabiso lenqaku labo le-yield (umda), iyunithi: MPa MPa (N / mm2); ngenxa yeempawu ezibanzi zoomatshini zamandla entsimbi ye-Q235, i-plasticity, ubulukhuni kunye nokuxinana kwintsimbi eqhelekileyo yesakhiwo sekhabhoni. Okuninzi, inokuhlangabezana ngcono neemfuno eziqhelekileyo zokusetyenziswa, ngoko ke ububanzi bokusetyenziswa bubanzi kakhulu.
2. Uhlobo lwaseJapan i-SPCC - Intsimbi, iP-P, iC-cold, iC-common yesine.
3. Inqanaba le-ST12 laseJamani - i-ST-steel (Steel), ishidi lesinyithi eliqengqelekayo elibandayo elinamaklasi ali-12.

Ukusetyenziswa kweCold Rolled Steel Coil

Ikhoyili eqengqelekayo ebandayo inokusebenza kakuhle, oko kukuthi, ngokuqengqeleka okubandayo, umcu oqengqelekayo obandayo kunye neshiti yentsimbi enobukhulu obuncinci kunye nokuchaneka okuphezulu kunokufumaneka, ngokuthe tye okuphezulu, ukuguda okuphezulu komphezulu, umphezulu ococekileyo nokhanyayo weshiti eqengqelekayo ebandayo, kunye nokugquma okulula. Ukucubungula okufakwe ipleyiti, iintlobo ngeentlobo, ukusetyenziswa ngokubanzi, kunye neempawu zokusebenza okuphezulu kokunyathela kunye nokungagugi, inqanaba eliphantsi lemveliso, ngoko ke ishiti eqengqelekayo ebandayo inoluhlu olubanzi lokusetyenziswa, olusetyenziswa kakhulu kwiimoto, kwiidrama zesinyithi eziprintiweyo, kulwakhiwo, kwizinto zokwakha, kwiibhayisekile, njl. Eli shishini likwayindlela engcono kakhulu yokuvelisa amaphepha esinyithi agqunywe yindalo.
