Umahluko phakathi kwentsimbi epholileyo kunye neshushu-eshushu

Kwishishini lensimbi, sihlala siva ingcamango yokutshisa okutshisa kunye nokubandayo okubandayo, ngoko ke yintoni na?

I-rolling yensimbi isekelwe ikakhulu kwi-hot rolling, kwaye i-cold rolling isetyenziselwa ukuveliswa kweemilo ezincinci kunye namaphepha.

 

Oku kulandelayo kukuqengqeleka okubandayo kwentsimbi kunye nokuqengqeleka okushushu kwentsimbi:

Ucingo: Ububanzi be-5.5-40 mm, imilo yekhoyili, zonke izinto ezishushu eziqengqelekayo.Emva komzobo obandayo, kuyatsalwa kubanda.

Intsimbi ejikelezileyo: Ukongeza kubungakanani obuchanekileyo bezinto ezikhanyayo ngokuqhelekileyo zishushu ziqengqeleke, zikho ne-forged (amanqaku okubumba ubuso).

Strip steel: Zombini ezishushu kwaye zibandayo, izinto eziqengqelekayo ezibandayo zihlala zibhityile.

Ipleyiti yentsimbi: ipleyiti eqengqelekayo ebandayo ibhityile ngokubanzi, njengepleyiti yeemoto;Kukho iipleyiti ezityebileyo ngakumbi ekuqengqelekeni okushushu, ezinobungqingqwa obufanayo nokuqengqeleka okubandayo, kwaye ukubonakala kwahlukile ngokucacileyo.

Intsimbi yeAngle: Yonke ishushu iqengqeleke.

Umbhobho wentsimbi: welding eshushu esongwayo kwaye ebandayo izotyiwe.

Umjelo kunye nentsimbi efana ne-H: i-hot rolled.

I-Rebar: imathiriyeli eshushu esongwayo.

 

I-Hot rolling kunye ne-cold rolling yinkqubo ye-steel plate okanye iphrofayili yokwenza iphrofayili, enempembelelo enkulu kwisakhiwo kunye neempawu zensimbi.

Ukuqengqeleka kwentsimbi kusekelwe ikakhulu kwi-hot rolling, kunye ne-cold rolling ngokuqhelekileyo isetyenziselwa ukuveliswa kwentsimbi echanekileyo njengentsimbi encinci kunye neshidi lensimbi.

Ubushushu bokupheliswa kokuqengqeleka okushushu ngokuqhelekileyo bungama-800 ~ 900 ° C, kwaye ke bupholiswa ngokubanzi emoyeni, ngoko ke imeko yokuqengqeleka eshushu ilingana nonyango oluqhelekileyo.

Uninzi lwentsimbi luqengqeleka ngokushushumbisa.Intsimbi ehanjiswa kwimeko eshushu, ngenxa yokushisa okuphezulu, ivelisa uluhlu lwe-oxide sheet phezu komhlaba, ngoko inokumelana nokugqwala okuthile kwaye inokugcinwa kwindawo evulekileyo.

Nangona kunjalo, lo maleko weshiti oxide kwakhona wenza umphezulu eshushu-role intsimbi rhabaxa, ukuguquguquka ubungakanani mkhulu, ngoko ke kufuna umphezulu ogudileyo, ubungakanani obuchanekileyo, iimpawu ezintle ngoomatshini zentsimbi, ukusebenzisa imveliso eshushu-isolwe semi-egqityiweyo okanye egqityiweyo. iimveliso njengemathiriyeli ekrwada kwaye emva koko imveliso ebandayo yokuqengqeleka.

 

Izinto eziluncedo:

Isantya sokubumba sikhawuleza, imveliso iphezulu, kwaye i-coating ayonakaliswanga, kwaye inokwenziwa kwiifom ezahlukeneyo zecandelo lomnqamlezo ukuhlangabezana neemfuno zemiqathango yokusetyenziswa;Ukuqengqeleka okubandayo kunokuvelisa i-deformation enkulu yeplastiki yentsimbi, ngaloo ndlela inyusa indawo yentsimbi yesivuno.
