Iindlela ezahlukeneyo zinokuvelisa iiprofayili zensimbi engenasici, zonke zibonelela ngeenzuzo ezahlukeneyo. Iinkangeleko ezishushu ziqengqiwe zineempawu ezithile ezikhethekileyo ngokunjalo.
I-Jindalai Steel Group yingcaphephe kwiiprofayili eziqengqelekayo kunye nokuqengqeleka okubandayo kweeprofayili ezikhethekileyo kwintsimbi kunye nentsimbi engatyiwayo. Thumela umbuzo wakho kwaye siya kukuvuyela ukubonisana nawe ngobuchule.
Ukuqengqeleka kweeprofayili kunokuthi kwenzeke kumaqondo obushushu aphezulu (hot rolling) okanye kwiqondo lobushushu begumbi (cold rolling). Ubushushu budlala indima ebalulekileyo ngokubhekiselele kwisiphumo. Ngazo zombini iitekhnoloji zemveliso, kunokwenzeka ukuvelisa iiprofayili ezishushu eziqengqelekayo okanye iiprofayili eziqengqelekayo ezibandayo kwintsimbi engenasici. Nangona kunjalo, iimpawu zazo zombini iindlela zibonisa umahluko ocacileyo.
IiProfayili eziQithiweyo ezishushu-Xa intsimbi engatyiwa zishushu ishushu
Ukuqengqeleka okushushu kwamacandelo yeyona teknoloji inemveliso yokuvelisa imivalo emide. Nje ukuba indawo yokusila imiselwe kwaye ilungele inkqubo yemveliso, inokutshisa iiprofayili zomqulu ngeemali ezinkulu ezinemveliso ephezulu. Ngokuqhelekileyo, ubushushu buphakama ngaphezu kwe-1.100 degrees Celsius. Ngoko iibhilidi okanye iintyatyambo zendlela yokuvelisa "yokuqala-yokuyeka" okanye iintambo zocingo "ezingapheliyo" zokutshisa ukufudumala ukuya kweli nqanaba. Uninzi lwezitendi eziziqengqelekayo ziyayikhubaza iplastiki. Ijometri kunye nobude beprofayili enqwenelekayo egqityiweyo eshushu eqengqelekayo imisela imilinganiselo kunye nobunzima bemathiriyeli ekrwada.
I-Hot rolling yindlela yeklasi yokuvelisa ubuninzi beemveliso ezide. Kuphela ngokuchaneka kunye nokugqitywa kwendawo, imida kufuneka yamkelwe.
Iiprofayili eziQingiweyo kunye neempawu zazo
Impahla ekrwada yeeprofayili zokuqengqeleka ezibandayo yintambo yocingo, eyimveliso egqityiweyo. Ububanzi bentonga buxhomekeke nakwicandelo lomnqamlezo wemveliso yokugqibela. Ngokufana ne-hot rolling engapheliyo, i-cold rolling nayo yinkqubo eqhubekayo, kodwa kwiqondo lokushisa. Umatshini wokuvelisa ukhokelela ucingo kwiindawo ezahlukeneyo kwaye ngoko udala imilo efunekayo kunye nokudlula okuninzi. Le nkqubo iyancipha ukhozo lwentsimbi, izinto ziba nzima kwaye umphezulu ugudile kwaye ucwebezele ngakumbi.
Kwiiprofayili ezintsonkothileyo, inkqubo yokuqengqeleka kaninzi ingafuneka. Kule meko, kufuneka sikhuphe iiprofayili ngaphambi kokuba sizisonge kwakhona.
Le teknoloji ivumela ukuvelisa iiprofayili ezinokunyamezela okuqinileyo. Yeyona ndlela ilungileyo yokuvelisa ukuvelisa iiprofayili ezikhethekileyo eziqengqelekayo ezincinci ukuya kumbindi kwintsimbi engatyiwayo.
Zombini itekhnoloji inophawu lwazo oluthile kunye neengenelo kunye nezinto ezingalunganga:
| Ukuqengqeleka okushushu | Ukuqengqeleka okubandayo | |
| Imveliso | Phezulu kakhulu | Phezulu kakhulu |
| Uluhlu lwecandelo | Phezulu kakhulu | Phezulu kakhulu |
| Uluhlu lwemilinganiselo | Phezulu kakhulu | Ilinganiselwe |
| Uluhlu lwezinto | Phezulu kakhulu | Phezulu |
| Ubude bebha | Ngobude obuqhelekileyo kodwa nakwiikhoyili ezikhoyo | Ngobude obuqhelekileyo kodwa nakwiikhoyili ezikhoyo |
| Ubuncinci bobungakanani | Phezulu | Phantsi |
| Misela iindleko | Phezulu kakhulu | Phezulu |
| Amaxesha okuhanjiswa | 3 - 4 iinyanga | 3 - 4 iinyanga |
| Ubungakanani bendawo | Inkulu kakhulu, ukuya kuthi ga kwikhilomitha enye ubude | Icwecwe |
| Ukuchaneka komgangatho | Phantsi | Phezulu kakhulu |
| Umgangatho womphezulu | rhabaxa | Kulungile kakhulu |
| Ixabiso leprofayile | Amaxabiso aphantsi ukuya kweliphakathi | Amaxabiso aphakathi ukuya phezulu |
AmaBanga ahlukeneyo eStainless Steel yeeProfayili eziQingiweyo eziHotyo kunye neeProfayili eziQingiweyo eziQhekekileyo
I-austenitic stainless steel grade eyaziwayo i-304, ngokulandelanayo i-304L, kunye ne-316 okanye i-316L kunye ne-316Ti ifanelekile ukuvelisa amacandelo ashushu okanye abandayo. Oku kukhusela ukufumaneka kweeprofayili zensimbi engenasici kwimarike. Amanye amabakala ensimbi engenasici alahlekelwa yinzuzo yawo yeempawu xa efudunyezwa kwaye ke imveliso yokugqibela inokuba nezinye izinto ezingafunekiyo. Ezinye iimathiriyeli zinokuba nzima kakhulu kwaye zomelele, yiyo loo nto ukuguqulwa okubandayo komatshini ngokuqengqeleka kwiqondo lobushushu begumbi akunakwenzeka.
