Udidi oluphambili lombhobho wentsimbi

Q345, 15CrMo, 12Cr1MoV, A53A, A53B, SA53A, SA53B

Ubungakanani betyhubhu yentsimbi engenamthungo kunye nokuphambuka okuvumelekileyo

Ityhubhu yentsimbi yekhabhoni (GB/8162-2008)

Olu hlobo lombhobho wentsimbi oluyilwe ngokuqhelekileyo lunyibilikiswa yi-converter okanye iziko elivulekileyo, izinto zalo ezisisiseko yintsimbi enyibilikisiweyo kunye nentsimbi elahliweyo, umxholo wesalfure kunye ne-phosphorus kwintsimbi uphezulu kunowombhobho wentsimbi oluyilwe carbon oluyilwe kumgangatho ophezulu, ngokubanzi i-sulfur ≤0.050%, i-phosphorus ≤0.045%. Umxholo wezinye izinto ezixutywayo, ezifana ne-chromium, i-nickel kunye nobhedu, eziswe kwintsimbi zizinto eziluhlaza ngokubanzi awudluli kwi-0.30%. Ngokweemfuno zokwakheka nokusebenza, umgangatho wolu hlobo lombhobho wentsimbi oluyilwe uboniswa yi-steel grade Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 njalo njalo.

Qaphela: “Q” luphawu lwefonetiki lwesiTshayina lwe-yield “qu”, lulandelwa lixabiso eliphantsi le-yield point (σ S) yebakala, lulandelwe luphawu ngokwezinto ezingacocekanga (i-sulfur, i-phosphorus) ukusuka phezulu ukuya ezantsi kunye notshintsho kwizinto zekhabhoni kunye ne-manganese, ezahlulwe zibe ziiklasi ezine u-A, u-B, u-C, u-D.

Olu hlobo lwemveliso yemibhobho yentsimbi yolwakhiwo lolona lukhulu, ukusetyenziswa kubanzi kakhulu, kuqengqeleka ngakumbi kwipleyiti, iprofayili (ejikelezileyo, eyisikwere, ethe tyaba, yomsebenzi, emiseleni, e-Angle, njl.njl.) kunye nombhobho wentsimbi welding weprofayili kunye nowemveliso. Isetyenziswa kakhulu kwizakhiwo zokusebenzela, iibhulorho, iinqanawa kunye nezinye izakhiwo kunye nemibhobho yokuthutha ulwelo ngokubanzi. Olu hlobo lwentsimbi lusetyenziswa ngokuthe ngqo ngaphandle konyango lobushushu.

Umbhobho wesinyithi oqinileyo we-alloy ephantsi (GB/T8162-2008)

Ukongeza kwinani elithile le-silicon okanye i-manganese, imibhobho yentsimbi iqulethe ezinye izinto ezifanelekileyo kwizixhobo zaseTshayina. Ezifana ne-vanadium (V), i-niobium (Nb), i-titanium (Ti), i-aluminium (Al), i-molybdenum (Mo), i-nitrogen (N), kunye nezinto ezinqabileyo zomhlaba (RE). Ngokweemfuno zekhemikhali kunye nokusebenza, umgangatho wayo umelwe yi-Q295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D, E kunye nezinye iintlobo zentsimbi, kwaye intsingiselo yayo iyafana nombhobho wesinyithi wekhabhoni.

Ukongeza kwintsimbi yebanga A kunye ne-B, intsimbi yebanga C, iBANGA D kunye neBanga E kufuneka iqulathe ubuncinane enye yezinto ezicociweyo zengqolowa ezifana ne-V, Nb, Ti kunye ne-Al. Ukuze kuphuculwe ukusebenza kwentsimbi, intsimbi yebanga A, B inokongezwa kwenye yazo. Ukongeza, umxholo wezinto eziseleyo ze-Cr, Ni kunye ne-Cu ungaphantsi kwe-0.30%. I-Q345A, B, C, D, E ziimpawu ezimele olu hlobo lwentsimbi, phakathi kwazo intsimbi yebanga A, B idla ngokubizwa ngokuba yi-16Mn; Kufuneka kongezwe izinto ezingaphezulu kwesinye kumbhobho wentsimbi webanga C nangaphezulu, kwaye kufuneka kongezwe ipropati enye yempembelelo ephantsi kubushushu kwiipropati zayo zoomatshini.

Umlinganiselo wolu hlobo lombhobho wesinyithi olwakhiwo kunye nesinyithi esinolwakhiwo lwekhabhoni. Unezibonelelo zamandla aphezulu, ukusebenza kakuhle okubanzi, ubomi benkonzo ende, uluhlu olubanzi lokusetyenziswa kunye noqoqosho oluthelekisekayo. Usetyenziswa kakhulu kwiibhulorho, iinqanawa, iibhoyila, izithuthi kunye nezakhiwo ezibalulekileyo.
