Yintoni umahluko phakathi kombhobho wentsimbi eshushu esongiweyo kunye nombhobho wentsimbi ongenamthungo oqengqiwe?
Imibhobho yentsimbi engenamthungo epholileyo eqengqelekayo idla ngokuba yidayamitha emincinci, kwaye imibhobho yentsimbi engenamthungo eshushu eqengqelekayo idla ngokuba mkhulu.
Imibhobho yentsimbi engenamthungo yahlulahlulwe yaba yimibhobho yentsimbi eshushu-eshushu (eyongeziweyo) engenamthungo kunye nemibhobho yentsimbi etsalwa ngokubanda (eqengqiwe) ngenxa yeenkqubo ezahlukeneyo zokwenza izinto.Iityhubhu ezibandayo (eziqengqelekayo) zahlulwe zibe ziityhubhu ezingqukuva kunye neetyhubhu ezinokwakheka okukhethekileyo.
1) Imibhobho engenamthungo eshushu eqengqelekayo ngeenjongo ezahlukeneyo yahlulahlulwe yaba yimibhobho yentsimbi eqhelekileyo, imibhobho yentsimbi ephantsi naphakathi yoxinzelelo oluphezulu, imibhobho yensimbi yoxinzelelo oluphezulu, imibhobho yentsimbi yealloy, imibhobho yentsimbi, imibhobho yokuqhekeka kwepetroleum, imibhobho yentsimbi yejoloji kunye neminye imibhobho yentsimbi. imibhobho yentsimbi encinci, imibhobho ye-oyile eqhekekileyo kunye neminye imibhobho yentsimbi, kunye nemibhobho yentsimbi enekhabhoni ebhityileyo, imibhobho yentsimbi ebhityileyo, kunye nemibhobho yentsimbi ebhityileyo.Umbhobho wentsimbi, umbhobho wentsimbi owenziwe ngendlela ekhethekileyo.
2) Idayamitha yangaphandle yemibhobho engenamthungo eshushu eqengqelekayo enobungakanani obahlukeneyo ngokuqhelekileyo ingaphezulu kwe-32mm, kwaye ubukhulu bodonga buyi-2.5-75mm. Ububanzi bombhobho ongenamthungo obandayo bunokufikelela kwi-6mm, kwaye ubukhulu bodonga bunokufikelela kwi-0.25mm. ukuqengqeleka okushushu.
3) Ukwahluka kwenkqubo 1. I-cold-rolled forming steel ivumela i-buckling yendawo yecandelo, elinokuthi lisebenzise ngokupheleleyo umthamo wokuthwala ibha emva kwe-buckling;ngelixa intsimbi eshushu-eshushu ayivumeli i-buckling yendawo yecandelo.
2. Izizathu zoxinzelelo olushiyekileyo lwentsimbi eshushu kunye nentsimbi epholileyo zihlukile, ngoko ke ukuhanjiswa kwinqanaba elinqamlekileyo likwahluke kakhulu.Ukusabalalisa uxinzelelo olushiyekileyo lwamacandelo entsimbi epholileyo epholileyo epholileyo igobile, ngelixa ukusabalalisa uxinzelelo olushiyekileyo lwamacandelo ensimbi ashushu okanye adibeneyo afana nefilimu.
3. Ukuqina kwe-torsional yamahhala yensimbi eshushu eshushu iphezulu kuneyentsimbi epholileyo, ngoko ke ukunyanzeliswa kwe-torsional ye-hot-rolled-rolled is better than the cold-rolled-rolled steel.
4) Iinzuzo ezahlukeneyo kunye nokungonakali Imibhobho epholileyo epholileyo engenamthungo ibhekisela kwiishiti zetsimbi okanye iintambo zetsimbi ezicutshungulwa kwiindidi ezahlukahlukeneyo zetsimbi ngokubanda, ukugoba okubandayo, kunye nokubandayo kwiqondo lokushisa.
Izinto eziluncedo: Isantya sokwenza ngokukhawuleza, isiphumo siphezulu, kwaye isambatho sonakaliswe, kwaye sinokwenziwa kwiintlobo ezahlukeneyo zecandelo elinqamlezayo ukuhlangabezana neemfuno zemiqathango yokusetyenziswa;ukuqengqeleka okubandayo kunokubangela ukuguqulwa kweplastiki enkulu yentsimbi, ngaloo ndlela kwandisa amandla esivuno sentsimbi.
Ukungalungi: 1. Nangona kungekho ukunyanzeliswa kwe-thermoplastic ngexesha lokuqulunqa, kusekho uxinzelelo oluseleyo kwicandelo, eliya kuchaphazela ngokuqinisekileyo iimpawu ze-buckling jikelele kunye neendawo zendawo;2. Intsimbi yecandelo elibandayo ngokuqhelekileyo licandelo elivulekileyo, elenza ukuqina kwe-torsional yamahhala yecandelo eliphantsi..3.Ubunzima bodonga lwentsimbi epholileyo buncinci, kwaye akukho bunzima kwiikona apho iiplate zixhunyiwe, kwaye ukukwazi ukuthwala imithwalo egxininisiweyo yendawo ibuthathaka.
Imibhobho engenamthungo eshushu-eqengqelekayo ihambelana nemibhobho engenamthungo epholileyo.
Izinto eziluncedo: Iyakwazi ukutshabalalisa isakhiwo sokuphosa se-ingot, ihlambulule ingqolowa yentsimbi, isuse iziphene zesakhiwo, yenza isakhiwo sensimbi sigxininise, kwaye siphucule iimpawu zomatshini.Olu phuculo lubonakaliswe ngokukodwa kwi-rolling direction, ukwenzela ukuba intsimbi ayisekho isotropic kwinqanaba elithile;amaqamza, iintanda kunye nokukhululeka okwenziwa ngexesha lenkqubo yokugalela nako kunokudityaniswa kubushushu obuphezulu kunye noxinzelelo oluphezulu.
Ukungalungi: 1. Emva kokutshisa okutshisayo, i-non-metallic inclusions (ikakhulukazi i-sulfides kunye ne-oxides, kunye ne-silicates) ngaphakathi kwentsimbi icinezelwe ibe ngamashidi amancinci, kwaye i-delamination (i-interlayer) iyenzeka.I-Delamination iyancipha kakhulu iipropati ezithintekayo zensimbi kwi-thickness direction, kunye nokukrazula kwe-interlaminar kubangelwa ukukrazula kwe-interlaminar kaninzi kubangelwa i-weldrinks yendawo. amaxesha amaninzi ukunyanzeliswa kwamanqaku esivuno, okungaphezulu kakhulu kunomthwalo obangelwa ngumthwalo;
2. Ukuxinezeleka okushiyekileyo okubangelwa ukupholisa okungalinganiyo.Uxinzelelo olushiyekileyo luxinzelelo lwangaphakathi lokuzilinganisa ngaphandle kwamandla angaphandle.Iziqendu ezishushu ezinqamlekileyo zamacandelo ahlukeneyo anqamlekileyo zineengcinezelo ezinjalo ezishiyekileyo. Ngokuqhelekileyo, ubukhulu becandelo leprofayili yentsimbi, ubukhulu boxinzelelo olushiyekileyo.Nangona uxinzelelo olushiyekileyo lusenalo intshukumo yangaphandle, impembelelo yangaphandle inamandla okusebenza, impembelelo yangaphandle inamandla okusebenza phantsi kwentsimbi. kuchaphazela kakubi i-deformation, ukuzinza kunye nokumelana nokukhathala.
3. Iimveliso zetsimbi ezishushu ezishushu azilula ukulawula ngokwemiqathango yobunzima kunye nobubanzi becala.Siqhelene nokwandiswa kwe-thermal kunye nokucutha.Kuba ekuqaleni, nangona ubude kunye nobukhulu bufikelela kumgangatho, kuya kubakho umahluko othile ongalunganga emva kokupholisa kokugqibela.Ubukhulu becala umahluko ongalunganga, ubukhulu becala kunye nokucaca ngakumbi ukusebenza.
