I-Carbon Steel Seamless Steel Tube-iQela laseRoyal

1. Ukuqengqeleka okushushu (umbhobho wentsimbi ongaphandle komthungo) : ityhubhu engqukuva ingenanto → ukufudumeza → ukugqobhoza → ukuqengqeleka kwediagonal ezintathu eziphezulu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa → ukuhluba → ukulinganisa (okanye ukunciphisa) → ukupholisa → ukulungisa → uvavanyo lwehydrostatic (okanye ukuhlola) → ukumakisha → indawo yokugcina
Izinto eziluhlaza ze-tube ejikelezayo i-tube billet ejikelezayo, i-embryo ye-tube ejikelezayo iyasikwa kwaye icutshungulwe ngomatshini wokusika kunye nokukhula malunga ne-1 mitha engenanto, kwaye ithunyelwe kwisithando somlilo ngokufudumeza ibhanti lokuhambisa. Ibillet yondliwa kwiziko kwaye ifudunyezwe malunga ne-1200 degrees Celsius. Amafutha yihydrogen okanye iacetylene. Ukulawulwa kweqondo lokushisa kwisithando somlilo yingxaki ephambili. Emva kokuba i-tube billet ejikelezayo iphuma, ihlanjululwe yi-punch yoxinzelelo. Ngokuqhelekileyo, i-perforator eqhelekileyo yi-conical roll perforator. Olu hlobo lwe-perforator lusebenza kakuhle kwimveliso, umgangatho omhle wemveliso, i-perforating diameter enkulu kwaye inokunxiba iindidi zentsimbi. Emva kokubhoboza, i-tube billet ejikelezayo iqhutywe ngokulandelelanayo nge-diagonal emithathu ephezulu, i-rolling eqhubekayo okanye i-extrusion. Emva kwe-extrusion, umbhobho kufuneka ususwe ukulinganisa. I-caliper ijikeleza kwi-embryo yensimbi ngokusebenzisa i-conical drill ngesantya esiphezulu ukugqobhoza imingxuma kwaye yenze imibhobho yentsimbi. Ububanzi bangaphakathi bombhobho wensimbi buchongwa ngubude obungaphandle bobubanzi be-drill drill bit. Emva kokulinganisa umbhobho wensimbi, ingena kwinqaba yokupholisa kwaye ipholile ngokutshiza amanzi. Emva kokupholisa umbhobho wensimbi, uya kulungiswa.

Indlela yokuqengqeleka komzobo obandayo (ukuqengqeleka) umbhobho wensimbi ongenamthungo unzima ngakumbi kunombhobho wensimbi oshushu (extrusion) ongenamthungo. Amanyathelo amathathu okuqala enkqubo yawo yokuvelisa ayafana. Umahluko ukusuka kwinqanaba lesine, ityhubhu ejikelezayo engenanto emva kokubetha, ukuya entloko, i-annealing. Emva kwe-annealing, ulwelo olukhethekileyo lwe-asidi lusetyenziselwa ukukha. Emva kokukhetha, ioli isetyenziswa. Oku kulandelwa unyango olukhethekileyo lobushushu lwetyhubhu ye-rebillet emva komzobo obandayo obandayo (i-cold rolling). Emva kokunyangwa kobushushu, iqondiswe.
