Yintoni imathiriyeli yeSS400? Liliphi ibakala elihambelana nentsimbi yasekhaya ye-SS400?

SS400yipleyiti yentsimbi yolwakhiwo lwaseJapan esemgangathweni ehambelana neJIS G3101. Ihambelana ne-Q235B kumgangatho welizwe laseTshayina, kunye namandla anamandla angama-400 MPa. Ngenxa yomxholo wekhabhoni ephakathi, inika iipropati ezibanzi ezilungelelanisiweyo, ukufezekisa ukulungelelaniswa okulungileyo phakathi kwamandla, i-ductility, kunye ne-weldability, okwenza kube yibakala elisetyenziswa kakhulu.
Umahluko phakathiQ235b Ss400:

Imigangatho eyahlukeneyo:
Q235Bilandela uMgangatho weSizwe waseTshayina (GB/T700-2006). U-“Q” ubonisa amandla esivuno, u-'235' ubonisa amandla esivuno asezantsi angama-235 MPa, kwaye u-“B” ubonisa umgangatho womgangatho. I-SS400 ilandela uMgangatho woShishino waseJapan (JIS G3101), apho i-"SS" ichaza intsimbi yesakhiwo kunye ne "400" ibonisa amandla okuqina angaphezu kwe-400 MPa. Kwimifanekiso yeplate yensimbi ye-16mm, i-SS400 ibonisa amandla emveliso ye-10 MPa ephezulu kune-Q235A. Zombini amandla okuqina kunye nobude bodlula ezo ze-Q235A.

 

Iimpawu zokuSebenza:

Kwizicelo ezisebenzayo, zombini amabakala abonisa ukusebenza okufanayo kwaye ahlala ethengiswa kwaye aqhutywe njengentsimbi yekhabhoni eqhelekileyo, kunye nokwahlukana kungabonakali kakhulu. Nangona kunjalo, ngokwembono yenkcazo eqhelekileyo, i-Q235B igxininisa amandla esivuno, ngelixa i-SS400 ibeka phambili amandla okuqina. Kwiiprojekthi ezineemfuno ezicacileyo zeepropathi zentsimbi, ukhetho kufuneka lusekelwe kwiimfuno ezithile.

 

Iipleyiti zentsimbi ze-Q235A zinoluhlu lwesicelo esincinci kune-SS400. I-SS400 ngokuyimfuneko ilingana ne-Q235 yaseTshayina (ilingana nokusetyenziswa kwe-Q235A). Nangona kunjalo, izikhombisi ezithile ziyahluka: I-Q235 ichaza imida yomxholo kwizinto ezifana ne-C, Si, Mn, S, kunye ne-P, ngelixa i-SS400 ifuna kuphela i-S kunye ne-P ibe ngaphantsi kwe-0.050. I-Q235 inamandla esivuno esidlula i-235 MPa, ngelixa i-SS400 ifezekisa i-245 MPa. I-SS400 (intsimbi yesakhiwo esiqhelekileyo) ichaza intsimbi yesakhiwo esiqhelekileyo esinamandla angaphezu kwama-400 MPa. I-Q235 ibonisa isinyithi esiqhelekileyo se-carbon structural kunye namandla okuvelisa ngaphezu kwe-235 MPa.

 

Izicelo ze-SS400: I-SS400 idla ngokuqengqeleka kwiintambo zocingo, imivalo ejikelezileyo, imivalo yesikwere, iiplathi ezisicaba, ii-angle bars, i-I-beams, amacandelo eshaneli, intsimbi yefestile yefestile, kunye nezinye iimilo zesakhiwo, kunye namacwecwe aphakathi. Isetyenziswa kakhulu kwiibhulorho, iinqanawa, izithuthi, izakhiwo kunye nezakhiwo zobunjineli. Isebenza njengemivalo yokuqinisa okanye ukwakhiwa kweetrasi zophahla lwefektri, iinqaba zothumelo lombane ophezulu, iibhulorho, izithuthi, iibhoyila, izitya, iinqanawa, njl. Iintsimbi zeBanga C kunye no-D nazo zinokusetyenziselwa usetyenziso olukhethekileyo.
