Yintoni i-SS400? Ithini intsimbi yasekhaya ehambelanayo ne-SS400?

SS400yipleyiti yesinyithi yesakhiwo sekhabhoni yaseJapan ehambelana neJIS G3101. Ihambelana neQ235B kumgangatho wesizwe saseTshayina, inamandla okutsalwa angama-400 MPa. Ngenxa yomxholo wayo wekhabhoni ophakathi, inika iipropati ezibanzi ezilungelelanisiweyo kakuhle, ifikelela kulungelelwaniso olufanelekileyo phakathi kwamandla, ukuguquguquka, kunye nokudityaniswa, okwenza ibe lolona didi lusetyenziswa kakhulu.
Umahluko phakathiQ235b Ss400:

Imigangatho eyahlukeneyo:
Q235Bilandela i-Chinese National Standard (GB/T700-2006). U-“Q” ubonisa amandla okuvelisa, u-'235' ubonisa amandla okuvelisa ubuncinci obuyi-235 MPa, kwaye u-“B” ubonisa umgangatho womgangatho. I-SS400 ilandela i-Japanese Industrial Standard (JIS G3101), apho u-“SS” ubonisa intsimbi yolwakhiwo kwaye u-“400” ubonisa amandla okuvelisa angaphezulu kwe-400 MPa. Kwiisampuli zepleyiti yentsimbi ye-16mm, i-SS400 ibonisa amandla okuvelisa angaphezulu kwe-10 MPa kune-Q235A. Amandla okuvelisa angaphezulu kunye nobude budlula obo be-Q235A.

 

Iimpawu Zokusebenza:

Kwizicelo ezisebenzayo, zombini ezi zigaba zibonisa ukusebenza okufanayo kwaye zihlala zithengiswa kwaye zicutshungulwa njengentsimbi yekhabhoni eqhelekileyo, umahluko ungacacanga kangako. Nangona kunjalo, ngokwembono yenkcazo eqhelekileyo, i-Q235B igxininisa amandla okuvelisa, ngelixa i-SS400 ibeka phambili amandla okutsalwa. Kwiiprojekthi ezineemfuno ezineenkcukacha zeempawu zoomatshini bentsimbi, ukhetho kufuneka lusekelwe kwiimfuno ezithile.

 

Iipleyiti zentsimbi ze-Q235A zinoluhlu oluncinci lokusetyenziswa kune-SS400. I-SS400 ilingana ne-Q235 yaseTshayina (ilingana nokusetyenziswa kwe-Q235A). Nangona kunjalo, izalathi ezithile zahlukile: I-Q235 ichaza imida yomxholo wezinto ezifana ne-C, i-Si, i-Mn, i-S, kunye ne-P, ngelixa i-SS400 ifuna kuphela i-S kunye ne-P ukuba zibe ngaphantsi kwe-0.050. I-Q235 inamandla okukhupha angaphezulu kwe-235 MPa, ngelixa i-SS400 ifikelela kwi-245 MPa. I-SS400 (isinyithi sesakhiwo ngokubanzi) imele intsimbi yesakhiwo ngokubanzi enamandla okukhupha angaphezulu kwe-400 MPa. I-Q235 imele intsimbi yesakhiwo eqhelekileyo yekhabhoni enamandla okukhupha angaphezulu kwe-235 MPa.

 

Ukusetyenziswa kwe-SS400: I-SS400 idla ngokusongwa kwiintambo zocingo, iibha ezijikelezileyo, iibha ezisikwere, iibha ezisicaba, iibha ze-engile, ii-I-beams, amacandelo etshaneli, intsimbi yefreyimu yefestile, kunye nezinye iimilo zesakhiwo, kunye neepleyiti ezinobukhulu obuphakathi. Isetyenziswa kakhulu kwiibhulorho, iinqanawa, izithuthi, izakhiwo, kunye nezakhiwo zobunjineli. Isebenza njengeebha zokuqinisa okanye ekwakheni ii-trusses zophahla lwefektri, ii-towers zothumelo oluphezulu, iibhulorho, izithuthi, ii-boilers, izikhongozeli, iinqanawa, njl. Ikwasetyenziswa kakhulu kwiindawo zoomatshini ezineemfuno zokusebenza ezingqongqo. Iintsimbi zeBanga C kunye ne-D nazo zingasetyenziselwa izicelo ezithile ezikhethekileyo.
