Intsimbi ejikelezayo ikakhulu ibandakanya intsimbi engqukuva nentsimbi yekhabhoni engqukuva:
1. Ngokwenkqubo, intsimbi ejikelezileyo ihlukaniswe kwiintlobo ezintathu: i-hot rolling, forging and cold drawing.Iimpawu zemivalo ejikelezayo eshushu i-5.5-250 mm, apho, imivalo emincinci ejikelezayo ye-5.5-25 mm ibonelelwa kakhulu kwiingxowa zeentambo ezichanekileyo, ezihlala zisetyenziswa njengemivalo yensimbi, iibholiti kunye neengxenye ezahlukeneyo zomatshini;imivalo engqukuva enkulu kune-25 mm ubukhulu becala Ukwenziwa kwamalungu omatshini, izikhala zetyhubhu zeetyhubhu zentsimbi ezingenamthungo, njl.
2. Ngokokwakheka kweekhemikhali, intsimbi yensimbi ejikelezayo (oko kukuthi, ngokubhekiselele kumxholo wekhabhoni) inokwahlulwa ibe yintsimbi ephantsi ye-carbon, i-medium carbon steel kunye ne-high carbon steel.
3. Ngokomgangatho wensimbi, intsimbi ejikelezayo inokwahlulwa ibe yintsimbi eqhelekileyo yekhabhoni kunye nekhwalithi ephezulu ye-carbon steel.
4. Ngokwenjongo, intsimbi ejikelezayo inokwahlulwa ibe yintsimbi ye-carbon structural kunye ne-carbon tool steel.
Intsimbi ejikelezayo ihlelwa ngokwenkqubo yokuvelisa: ihlulwe ibe ziindidi ezintathu: i-hot rolling, forging and cold drawing.
I-Hot rolling round steel yindlela yokucubungula uxinzelelo apho i-billet yensimbi idluliswa kwi-pair of rolls ejikelezayo (iimilo ezahlukahlukeneyo), kwaye icandelo lezinto eziphathekayo liyancitshiswa kwaye ubude bunyuswa ngenxa yokunyanzeliswa kokwenza kunye nokuqengqeleka kwemiqulu.Le yeyona ndlela isetyenziswa ngokuqhelekileyo kwimveliso yentsimbi.Isetyenziselwa ikakhulu ukuvelisa iiprofayili, iipleyiti kunye nemibhobho.
Intsimbi engqukuva eyenziweyo: ibhekisa kwintsimbi engqukuva enokubunjwa ngokubunjwa.Ngokubanzi, umgangatho wentsimbi ejikelezayo eveliswa yindlela yokugoba simahla ingcono phantsi kweemeko zomlinganiselo ofanayo wokuguqulwa, kuba ukunyathela ukufikelela kwixabiso elifanayo le-deformation yokuqengqeleka kufuna ukubunjwa ngokuphindaphindiweyo ukuze kunwebe (ukubunjwa kwe-deformation simahla kunye nokuqengqeleka kwayo. is contrained deformation), ngoko i-billet efanayo ivelisa intsimbi efanayo egqityiweyo ejikelezayo ilingana nokunyuka kwe-deformation ratio yokuqengqeleka ngaphezu kwe-50%.Ukongezelela, ngokubanzi, ukukhwabanisa yi-deformation epheleleyo yentsimbi ukusuka kumphezulu ukuya ngaphakathi kunye nomgangatho ojikelezayo uphazamisekile kuqala, ngoko Isakhiwo sangaphakathi, isidanga sokwahlula, umgca wokuhamba kwesinyithi, njl. zahluke ngokupheleleyo, kwaye umgangatho wemivalo engqukuva engumjikelo ungcono jikelele kunowo wemivalo engqukuva.Ke ngoko, amacandelo aphambili anjengeentloko ze-crane hook kufuneka abe ngamalungu abunjiweyo.
Intsimbi engqukuva ebandayo: ekwaziwa ngokuba yintsimbi engqukuva ebandayo, intsimbi etsalwa ngokubanda, intsimbi engqukuva ebandayo, kunye nentsimbi engqukuva egudileyo, luhlobo lwentsimbi yecandelo elitsalwa ngokubanda.Nokuba yintsimbi engqukuva etsalwa ngokubanda okanye intsimbi engqukuva, imilo yayo ingqukuva, kodwa umphezulu wentsimbi engqukuva etsalwa ngokubanda igudile kakhulu, ukuchaneka kwayo kuphezulu, kwaye iimpawu zayo zomatshini ziphezulu.Ngenxa yokuchaneka kwayo okuphezulu, inokusetyenziswa ngokuthe ngqo ngaphandle kokucubungula.
Intsimbi ejikelezileyo inamathuba okusebenza okubanzi kwaye isetyenziswa ngokubanzi kwi-hardware, ukwakhiwa, iimoto, ukwakhiwa kweenqanawa, ii-petrochemicals, oomatshini, amayeza, ukutya, umbane, amandla, i-aerospace, njl., umhlobiso wokwakha.Eyona ndlela ibanzi yokusetyenzwa kweendawo eziqhelekileyo zoomatshini, iinxalenye zentsimbi yentonga ngokubanzi, iirodi zeCD, iibholiti, iindongomane.
| Ukupakishwa | Ukupakishwa kokuthumela ngaphandle okusemgangathweni okulungele ulwandle, ezinye iintlobo zokupakisha zinokwenziwa ngokwezifiso njengemfuno zonke. |
| Ukupakishwa kokuthumela | Idityaniswe ngeentambo zentsimbi eziqinileyo, kulula ukulayishwa kunye nokothula. |
