Inqubo yokukhiqiza ipayipi yensimbi enengcindezi ephezulu kanye nokugcinwa kwayo okulula
Inqubo yokukhiqiza eyinhloko yepayipi yensimbi ephezulu yokucindezela: ukushisa kwe-billet, i-perforated tube, isandiso sepayipi.Ukugingqika kwepayipi lensimbi elinomfutho ophezulu, usayizi wamapayipi, ipayipi lokunciphisa, insimbi yokupholisa kanye nensimbi yokuqedela noma kungathiwa insimbi enezimbobo ezinezimbobo ezishisayo, i-embryo eshisayo egoqiwe yokufaka isifutho sekhanda esike imoto edonsayo...Funda kabanzi -
Umehluko we-Hot-rolled kanye ne-Cold-drawn
I-hot-rolled isekelwe ku-slab (ikakhulukazi i-billet) njengento eluhlaza, eshisiswe umshini wokugaya kanye neqembu lokugaya elenziwe ngensimbi.Kusukela ekuqedeni okokugcina kumshini wokugaya oshisayo ngokupholisa i-laminar kuya kumazinga okushisa amisiwe, umshini wokugoqa wawugoqa amakhoyili emichilo yensimbi, i-steel roll ipholiswe...Funda kabanzi -
ukungalungi kwamapayipi ashiselwe
Ipayipi lensimbi elishiselwe ukukhiqizwa ku-inthanethi okuqhubekayo, ukushuba kokuqina, iyunithi enkulu futhi incibilikisa utshalomali lwemishini, lapho kunokonga futhi kusebenza kancane.Ukuqina kodonga oluncane, isilinganiso salo sokufaka-okukhiphayo sizoncishiswa.Izinzuzo kanye nokubi kwenqubo ye-t...Funda kabanzi -
