Ikhoyili yentsimbi eqengqelekayo ye-SPCC ebandayo

Umfanekiso oBonisiweyo we-SPCC Cold Rolled Steel Coil

Inkcazo emfutshane:

Igama: Ikhoyili yentsimbi eqengqelekayo ebandayo

Intsimbi yekhabhoni eqengqelekayo ebandayo (SPCC, SPCD, SPCE), intsimbi yekhabhoni ephantsi kunye nentsimbi yekhabhoni ephantsi kakhulu (DC01/St12, DC03/St13, DC04/St14), intsimbi yokunyathela iimoto (DC01-Q1, DC03-Q1, DC04 -Q1), imicu yentsimbi yekhabhoni eqengqelekayo ebandayo (Q235, St37-2G, S215G), imicu yentsimbi eqengqelekayo ebandayo enamandla aphantsi (JG300LA, JG340LA), njl.

Uluhlu lobukhulu: 0.1mm-0.45mm

ububanzi bobubanzi: 700mm-1000mm

Izinto eziphathekayo: SPCC, SPCC, SPCD, SPCE, DC01, St12, DC03, St13, DC04, St14, Q235, St37-2G, S215G, JG300LA, JG340LA

Iimpawu: Ngenxa yokuba ayifakwanga, ubulukhuni bayo buphezulu kakhulu (i-HRB ingaphezulu kwama-90), kwaye ukusebenza komatshini kuphantsi kakhulu. Kungenziwa inkqubo elula yokugoba kwicala elingaphantsi kwama-90 degrees (ethe nkqo kwicala elijikajikayo). Ezinye iimatshini zentsimbi zinokuvelisa ukucutshungulwa okuphindwe kane.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Isishwankathelo sekhoyili eqengqelekayo ebandayo

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.

Inkqubo yokuvelisa iCold Rolled Coil

Ikhoyili eqengqelekayo ebandayo yenziwe ngekhoyili eqengqelekayo eshushu, kwaye inkqubo yayo yokuvelisa idla ngokudlula kwiinkqubo eziphambili ezifana nokulungiswa kwezinto eziluhlaza, ukuqengqeleka okubandayo, unyango lobushushu, ukulinganisa kunye nokugqiba.

Ukusebenza kweMveliso yeCold Rolled Coil

Iroli kunye nethebhulethi ziphantse zibe yipakethe esikiweyo. Ikhoyili ebandayo ifunyanwa ngokuyikha nokuyikha ngokubandayo. Kunokuthiwa luhlobo lwekhoyili ebandayo eqengqelekayo. Ikhoyili ebandayo eqengqelekayo (imeko eyongeziweyo): Ikhoyili eshushu eqengqelekayo ifunyanwa ngokuyikha, ukuyikha ngokubandayo, ukuyikha ngokubandayo, ukuyikha ngokungqongqoza, ukuyikha ngokungqongqoza, ukuyikha ngokungqongqoza, ukuyikha ngokungqongqoza.

Kukho umahluko omkhulu phakathi kwazo ezintathu:

Ngokwembonakalo, i-coil ebandayo iyonakele kancinci.

Amaphepha aqengqelekayo abandayo afana nomgangatho womphezulu, ulwakhiwo kunye nokuchaneka kobukhulu bawo angcono kuneekhoyili ezibandayo.

Ngokuphathelele ukusebenza, i-coil ebandayo efunyenwe ngqo emva kwenkqubo yokuqengqeleka ebandayo ye-hot rolled coil iyaqina xa iqengqeleka ebandayo, nto leyo ebangela ukwanda kwamandla okuvelisa kunye nenxalenye yoxinzelelo lwangaphakathi oluseleyo, kwaye inkangeleko yangaphandle "inzima". Ibizwa ngokuba yi-coil ebandayo.

Ngoko ke, amandla okuvelisa: ikhoyili ebandayo inkulu kunekhoyili eqengqelekayo ebandayo (imeko eyongeziweyo), ukuze ikhoyili eqengqelekayo ebandayo (imeko eyongeziweyo) ilungele ngakumbi ukunyatheliswa. Ngokubanzi, imeko yokuhanjiswa okuzenzakalelayo kweekhoyili eziqengqelekayo ezibandayo iyayongezwa.

Ukusetyenziswa kweshiti yentsimbi eqengqelekayo ebandayo

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.

Uluhlu lwesicelo:
(1) Ukucutshungulwa kube yi-cold rolling eqhelekileyo emva kokugquma;
(2) Iyunithi yokugquma isinyithi enesixhobo sokucoca ngaphambi kokuba kusetyenziswe isinyithi iyacutshungulwa ukuze igqume isinyithi;
(3) Iiphaneli ezingadingi ukucutshungulwa konke konke.
