6. Inkqubo yoMveliso - Umbhobho weNsimbi we-ERW / HFW
Ukuhlolwa kwezinto eziluhlaza:Iikhoyili zentsimbi ezingenayo ziyaqinisekiswa ukuba zenziwe ngamakhemikhali, iimpawu zoomatshini, kunye nomgangatho womphezulu. Ikhoyili nganye inikwe inombolo yobushushu eyahlukileyo ukuze ilandeleke ngokupheleleyo.
Ukuvula kunye nokulinganisa:Iikhoyili ziyavulwa zize zilinganiswe ukuze zithe tyaba umcu kwaye zisuse iseti yeekhoyili, ukuqinisekisa ukuba zithe tyaba ngokulinganayo ukuze zihlale zimile.
Ukusila kunye nokuSika imiphetho:Zombini imiphetho yomcu zigaywa ukuze zikwazi ukumelana nobubanzi obuchanekileyo (± 0.5mm), nto leyo eyenza umphezulu ococekileyo nohambelanayo ukuze kwenziwe i-weld esemgangathweni ophezulu.
Ukwenziwa Komkhuhlane:Umcu olinganisiweyo udlula kwimiqulu eyenza imiqulu ethi kancinci kancinci ibumbe umcu othe tyaba ube yiqokobhe letyhubhu elivulekileyo eliyi-cylindrical.
Ukuwelda Okuphindaphindwayo (HFW/ERW):Umbane ohamba rhoqo (200-500 kHz) ufudumeza imiphetho yokudibana ukuya kubushushu bokubumba (1,350-1,500°C). Iiroli zokucinezela zicinezela imiphetho eshushu kunye, zenze i-weld eyenziweyo ngaphandle kwezinto zokuzalisa.
Ukususwa kweeBead eziWeldiweyo:I-flash yangaphakathi neyangaphandle isuswa zii-carbide scarfing blades xa ishushu, nto leyo evelisa umphezulu ogudileyo ongenazo izixhobo zokuwelda ezininzi.

9. Ukupakishwa kunye nokuthunyelwa
Iipayipi ze-ERW ziyapakishwa kwaye zithunyelwa ngononophelo olukhulu ukuqinisekisa ukhuseleko lwazo ngexesha lokuhamba. Nantsi inkcazo yenkqubo yokupakisha nokuthumela:
Ukupakisha:
Ukwaleka okuKhuselekileyo:Ngaphambi kokupakisha, imibhobho inokugqunywa ngomaleko omncinci weoyile yokulwa nomhlwa okanye ivanishi yokukhusela ukuthintela ukugqwala komphezulu kunye ne-oxidation ngexesha lokugcina kunye nokuthuthwa. Isiphelo esingenanto sikwafumaneka ukuze sisetyenziswe ngoko nangoko kwindawo oya kuyo.
Ukudibanisa:Iipayipi ezinobukhulu obufanayo kunye neenkcukacha ezifanayo zihlanganiswa ngononophelo zibe ziibhanti ezizinxantathu okanye ezizinxantathu. Ziqiniswe kusetyenziswa iibhanti zentsimbi (ngesiqhelo iibhanti ezi-3-5 ngebhanti nganye) ukuthintela intshukumo ngaphakathi kwibhanti.
Iintloko zokuphela:Izigqubuthelo zeplastiki (PE okanye PP) zibekwe kuzo zombini iziphelo zombhobho ngamnye ukukhusela iziphelo ezibhityileyo, iziphelo ezicacileyo, kunye noqhagamshelo olunemisonto kumonakalo obangelwe yimpembelelo, ukungena kwenkunkuma, kunye nokufuma.
Ukugquma kunye nokugquma:Kwiiodolo zokuthumela ngaphandle ezikumgangatho ophezulu, izinto zokugquma ezifana neeringi zefoam okanye imicu yerabha zingasetyenziswa phakathi kweengqimba zemibhobho ukuthintela ukurhawuzelelwa kunye nokonakala kwengubo ngexesha lokuphathwa.
Iibhokisi okanye iiCases zoMthi:Kwiipayipi ezibhityileyo, iityhubhu ezichanekileyo, okanye iiodolo zokugquma eziphezulu, iipayipi zinokupakishwa kwiikreyithi zokhuni eziqinileyo okanye kwiikheyiphu zeplywood ukubonelela ngokhuseleko oluphuculweyo kwimikhosi yangaphandle kunye nokuphathwa rhabaxa.
Ukuhambisa ngenqanawe:
Indlela Yothutho:Iipayipi zithunyelwa ngeenqanawa zesikhongozeli (20ft/40ft), izithuthi ezinkulu, okanye imithwalo kaloliwe kuxhomekeke kwindawo oya kuyo, umthamo, kunye nokungxamiseka. Imithwalo emoyeni iyafumaneka ukuze isampuli okanye ithunyelwe ngexesha elifanelekileyo.
Ukufakwa kwiikhonteyina:Iiodolo ezincinci ukuya kweziphakathi ezilayishwa kwiikhonteyina zokuthutha eziqhelekileyo, zikhusela imithwalo kwimozulu, ukufuma, kunye nezinto ezingcolisayo zangaphandle ngexesha lokuhamba.
Ukulayisha inqanawa enkulu:Ii-odolo ezinkulu (ezihlala zingaphezulu kweetoni ezingama-200) zilayishwa ngqo kwiinqwelo zokuthwala impahla ezinkulu. Iiplanga zokuphakamisa kunye neebhari zokusasaza zithintela umonakalo; zigubungele kwaye zibophe imithwalo ekhuselekileyo elwandle.
Ukubhala iilebheli kunye namaxwebhu:Iphakheji nganye ibhalwe ngokucacileyo ngomgangatho, umgangatho, ubungakanani, inombolo yobushushu, kunye nemiyalelo yokuphatha. Amaxwebhu apheleleyo (i-invoyisi yorhwebo, uluhlu lokupakisha, i-invoyisi yemithwalo, iSatifikethi seMvelaphi, iZatifikethi zoVavanyo lweMill) alungiselelwe ukususwa kwempahla ngendlela ethe tye.
Ukubopha Okukhuselekileyo:Iibhanti zibotshelelwe ngentambo yentsimbi, iingxowa ze-dunnage, okanye izixhobo zokubopha iinkuni ukuthintela ukushukuma, ukuqengqeleka, okanye ukonakala ngexesha lokuhamba.
Ukulandelela kunye ne-inshurensi:Iinombolo zokulandelela iikhonteyina zibonelelwe ukuze kujongwe ngexesha langempela. I-inshurensi yemithwalo yaselwandle (Yonke Ingozi okanye Ngomndilili) iyafumaneka xa iceliwe.
Ngamafutshane, iWomic Steel iqinisekisa ukuba zonke iipayipi ze-ERW Steel zipakishwe ngamanyathelo okukhusela aphambili kushishino kwaye zithunyelwa kusetyenziswa iindlela zothutho ezithembekileyo ukuze zifike kwindawo eziya kuyo zikwimeko efanelekileyo. Iinkqubo ezifanelekileyo zokupakisha nokuthumela zibalulekile ekugcineni ukuthembeka kunye nomgangatho weemveliso ezihanjiswayo.
