Incazelo emfushane:
Amapayipi ensimbi asetshenziswa ngomshini noma ezingxenyeni ezakhiwe zezimboni, izimoto, imishini yezolimo, izindiza, ezokuthutha, ukuphatha impahla kanye nempahla yasendlini.Ikhiqizwa ukuze ilingane nobubanzi obungaphandle nobukhulu bodonga.
Imishini eqhutshwa kahle, ithimba labadayisi abaqeqeshiwe, nezinsizakalo ezingcono zangemuva kokuthengisa;Futhi siwumndeni omkhulu obumbene, wonke umuntu unamathela enanini lenkampani “ubunye, ukuzinikela, ukubekezelelana” kwe-Cold Rolled Drawn Steel Tube Seamless Precision C20, C45, S235, S355, 1020, 1045, 4130, 4140, Sizonikela kakhulu ikhwalithi ephezulu esebenzayo, okungenzeka ukuthi iyinani elinamandla kakhulu emkhakheni, kumakhasimende amasha namadala anazo zonke izinkonzo eziluhlaza ezinhle kakhulu.
Imishini eqhutshwa kahle, ithimba labadayisi abaqeqeshiwe, nezinsizakalo ezingcono zangemuva kokuthengisa;Futhi siwumndeni omkhulu obumbene, wonke umuntu unamathela enanini lenkampani “ubunye, ukuzinikela, ukubekezelelana” , Inhloso yethu “ukunikeza imikhiqizo nezixazululo zesinyathelo sokuqala kanye nensizakalo engcono kakhulu kumakhasimende ethu, ngakho besinesiqiniseko sokuthi kufanele inzuzo elinganiselwe ngokusebenzisana nathi”.Uma unentshisekelo kunoma yiziphi izimpahla zethu noma ungathanda ukuxoxa nge-oda langokwezifiso, qiniseka ukuthi uzizwa ukhululekile ukusithinta.Sibheke ngabomvu ukwakha ubudlelwano bebhizinisi obuyimpumelelo namakhasimende amasha emhlabeni jikelele maduze nje.
Amashubhu omshini asetshenziswa ekusetshenzisweni kwemishini kanye nesakhiwo esilula.
Amashubhu omshini akhiqizwa ukuze ahlangabezane nezidingo ezithile zokusetshenziswa kokuphela, ukucaciswa, ukubekezelela kanye nezakhiwo zamakhemikhali.
Amapayipi okusebenza kwemishini nesakhiwo esikhanyayo.Lokhu kuvumela ukufana okuqondile kwezakhiwo kulo lonke ipayipi uma kuqhathaniswa namapayipi ajwayelekile noma amapayipi.Amashubhu omshini angakhiqizwa ngezincazelo ezijwayelekile lapho kudingeka, kodwa ngokuvamile akhiqizwa ukuze asebenze "okuvamile", ngokugxila okuyinhloko emandleni esivuno sobukhulu obunembile nokuqina kodonga.Kwezinye izinhlelo zokusebenza ezakhiwe kakhulu, amandla okukhiqiza angase angacaciswanga, futhi ukukhiqizwa kwamashubhu omshini "kufanelekile ukusetshenziswa".Amapayipi omshini afaka phakathi izinhlobonhlobo zezinhlelo zokusebenza ezihlelekile nezingezona ezakhiwe.
Sisebenzisa ubuchwepheshe bethu be-metallurgical kanye nokukhiqiza ukuze senze imikhiqizo yeshubhu yemishini engenamthungo esebenza kahle kakhulu ukuze ihlangabezane nezidingo zakho.
Lokhu kuhlanganisa ikhabhoni, ama-alloys ngisho namamaki ensimbi angokwezifiso;i-annealed, normalized and tempered;ukucindezeleka kukhululiwe futhi kukhululekile ukucindezeleka;futhi wacima futhi waba nolaka.
Amapayipi ensimbi angenamthungo emishini nezimoto, asetshenziswa ekwenzeni nasekucubunguleni isiqu semoto namapayipi e-asi engemuva, okokusebenza okunembayo, amathuluzi namathuluzi.
Uhlaka lwemoto kanye neshubhu ye-axle yangemuva.
Ukukhiqiza nokucutshungulwa kwemishini enembayo, amathuluzi namathuluzi.
Imigomo yokulethwa: GBK, BKS, BK, BKW, NBK.
Hlola futhi uhlole:Ukwakheka kwamakhemikhali, izici zemishini, ukubukeka nokuhlolwa kobukhulu, ukuhlola okungabhubhisi, ukuhlolwa kosayizi wezinhlayiyana.
Ukwelashwa kwendawo:Ukucwiliswa kwamafutha, ukuvanisha, ukuchama kwesibhamu.
