- Yintoni icoil epholileyo
I-coil rolling ebandayo, eyaziwa ngokuba yi-CRC, luhlobo lwemveliso yentsimbi eyenziwe ngentsimbi eshushu eqengqelekayo kwaye ibonakala ngobunzima obuncinci kunye nezicelo ezithile.
Insimbi epholileyo ibhekisela kwintsimbi ephantsi kwekhabhoni eveliswa yindlela "yokuqengqeleka ebandayo" kwaye icutshungulwe kufuphi namaqondo okushisa aqhelekileyo.Intsimbi epholileyo epholileyo inika amandla aphezulu kunye nokusebenza.Amashiti entsimbi apholileyo asetyenziswa ngokuqhelekileyo kwiimveliso zobunjineli apho ukunyamezela okuqinileyo, ukugxila, ukuchaneka kunye neendawo ezigqunywe zifunekayo.
Intsimbi epholileyo eqengqelekayo iveliswa kumatshini wokunciphisa ukubanda apho izinto zipholile kufutshane neqondo lobushushu begumbi, kulandele i-annealing kunye / okanye i-temers rolling.Le nkqubo ivelisa intsimbi enoluhlu olubanzi lokugqitywa kwendawo kwaye iphezulu ekunyamezeleni, ukugxila, kunye nokuthe tye xa kuthelekiswa nentsimbi eshushu.Intsimbi epholileyo epholileyo iqulethe umxholo wekhabhoni ephantsi, kwaye indlela yokucima ibenza ibe thambile kuneshiti elishushu.Iimveliso zetsimbi ezibandayo ziveliswa ngokuqhelekileyo kumaphepha, imichilo, imivalo kunye neentonga.
2.Ukuhlelwa kwekhoyili epholileyo, uluhlu lwemveliso kunye neempawu
Imigangatho esetyenziswa kumazwe ahlukeneyo ukubeka iimfuno zentsimbi epholileyo, njenge-EN 10130, EN 10268, EN 10209, ASTM A1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045, GOST 17066 kunye namanye amabakala ensimbi kunye nabanye. ububanzi besayizi yeekhoyili ezipholileyo, ukusetyenziswa kwazo (iprofayili, ukubumba okubandayo, i-enamelling, ukusetyenziswa ngokubanzi, njl njl), iimpawu zomatshini, umgangatho womhlaba kunye nezinye iiparameters.
3.Iikhoyili ezibandayo ngokwemigangatho yaseYurophu
Eyona migangatho ilandelwa rhoqo yaseYurophu ekuveliseni iikhoyili eziqengqelekayo yi-EN 10130, EN 10268 kunye ne-EN 10209.
I-EN 10130 isetyenziswa kwiikhoyili ezipholileyo ezenziwe ngekhabhoni ephantsi DC01, DC03, DC04, DC05, DC06 kunye ne-DC07 amanqanaba entsimbi yokwenza abandayo ngaphandle kokugquma, kunye nobubanzi obuncinci be-600 mm kunye nobukhulu obuncinci be-0.35 mm.
4.Iimpawu zeCold Rolled Coil
Iimpawu eziphambili zeekhoyili ezipholileyo zibandakanya ukunyamezela okuchanekileyo kwe-dimensional, iipropathi eziphuculweyo zomatshini, kunye nomgangatho ongcono womphezulu kunamaphepha ashushu.
Ukuqengqeleka okubandayo kwenza ukuba kube lula ukwenza amacwecwe entsimbi amancinci angenakuveliswa kwiindawo zokusila ezishushu.Amashishini aphambili apho iikhoyili ezipholileyo zisetyenzisiweyo ziquka ukwakhiwa komatshini, iimpahla zabathengi, ukwakhiwa, iimoto.Xa kuziwa kushishino lokwakha, iikhoyili ezibandayo zisetyenziselwa ukuvelisa izinto ze-façade, izakhiwo zetsimbi, i-bent evaliweyo kunye neeprofayili ezivulekileyo, njl.
