Ukugqobhoza linyathelo lokuqala lokushushu-rolwaumbhobho wentsimbi ongenamthungodeformation, kunye nendima yayo kukuqina kwetyhubhu yebillet enxibe njengecapillary.Ngenxa yokugqoka i-capillary surface defects okanye i-eccentric (ubunzima obungalinganiyo) kunzima ukuphelisa okanye ukunciphisa inkqubo ye-deformation, ngoko ke, umgangatho we-capillary ene-perforated unempembelelo ebaluleke kakhulu kumgangatho we-hot-rolled seamless steel pipe.Indlela yoxinzelelo lwetyhubhu yokugqobhoza ukugqobhoza, ukugqobhoza okujikelezayo kunye nokugqobhoza.Intsimbi eshinyeneyo engenamthungo esetyenziswa ikakhulu kwipetroleum geology yokomba umbhobho, i-petrochemical esetyenziswa kwiityhubhu eziqhekekileyo, iityhubhu zebhoyila, imibhobho kunye neebheringi zemoto, iitrektara, inqwelomoya kunye nolunye ulwakhiwo lwetyhubhu echanekileyo, inkqubo yayo yokuvelisa: ityhubhu yentsimbi eshushu eqengqelekayo.→ukufudumeza→ezintathu ezinemingxuma rolling rolling, rolling okanye extrusion→bahlukane→ukulinganisa (okanye ukunciphisa) ukupholisa→ukulungisa→uvavanyo lwe-hydrostatic (okanye uvavanyo) uphawu→yokugcina.

Ukuphosa i-ingot yensimbi eshushu eqengqelekayo kunokutshabalalisa izicubu, ukucokiswa kweenkozo zentsimbi kunye nokuphelisa iziphene ze-microstructure, ukuze kuphuculwe iipropathi zentsimbi ezishinyeneyo.Olu phuculo lubonakaliswa ngokuyintloko kwindlela ehamba ngayo kwi-rolling direction ukuya kwinqanaba elithile kwintsimbi ayisekho isotropic;ukugalela amaqamza enziweyo, iintanda kunye nokukhululeka, zinokudityaniswa kwiqondo lobushushu eliphezulu kunye noxinzelelo.

Emva ityhubhu yentsimbi engenamthungo eshushu-eqengqelekayo ebhakiweyo ukuya kugqobhozo lwepuncher yoxinzelelo.Ngokuqhelekileyo i-punch eqhelekileyo i-tapered roller punching machine, umatshini wokubhoboza onjalo ukuphumelela okuphezulu kwemveliso, umgangatho wemveliso, umthamo owenziwe nge-forated, unokunxitywa iindidi zentsimbi.Emva kokubhoboza, ityhubhu ejikelezileyo iye yaqengqeleka kathathu, iqengqeleka okanye i-extrusion.Ukucudisa umbhobho emva kokulinganisa.Ilitye lokusila libe yintsimbi ejikelezayo ejikelezayo ngentsimbi enemingxuma eyenziwe ngentsimbi.Umbhobho ongaphakathi kwidayamitha umiselwa yidayamitha yangaphandle yokulinganisa ubude bokomba.Emva kokulinganisa umbhobho kwinqaba yokupholisa ngombhobho wokupholisa wesitshizi emva kokupholisa, kuyimfuneko ukuba iqondiswe.Emva kokulungelelanisa ibhande lokuhambisa intsimbi kumatshini wokukhangela isinyithi (okanye uvavanyo loxinzelelo) kuvavanyo lwangaphakathi.Ukuba umbhobho wangaphakathi uyaqhekeka, amaqamza kunye neminye imiba, iya kufunyanwa.Emva kokukhethwa kwentsimbi kodwa nangencwadana engqongqo yokulawula umgangatho.Emva komgangatho wentsimbi, fafaza ipeyinti kwinani, ubungakanani, inombolo yebhetshi njalo njalo.Ngekhreyini engena kwindawo yokugcina impahla.
