Sitshele ukuthi steel constructional

Ukusetshenziswa steel Sekuyisikhathi eside kakhulu angene ezimpilweni zethu futhi akubangi ukungabaza bakwazi yayo. Kodwa akufanele sikhohlwe ukuthi steel kungaba ezahlukene. Namuhla egqanyisiwe izinhlobo eziningana impahla:

1. Insimbi yesakhiwo.
2. Ithuluzi steel.
3. Steel izinjongo umuntu anezakhi ezikhethekile.

Asikhulume namuhla mayelana lezinsimbi kwesakhiwo. ngokuthi Ngakho zonke izinhlobo, ezisetshenziswa emsebenzini wokukhiqiza wokwakha izakhiwo, kanye izingxenye imishini futhi izindlela.

izinhlobo impahla

Insimbi yesakhiwo is zihlukaniswe ngamaqembu amabili amakhulu:

1. Eliphezulu ingxubevange kwesakhiwo.
2. Eliphezulu carbon kwesakhiwo.

Zonke lezi zinhlobo asetshenziswa endaweni ethile zokukhiqiza, ekuqhubeni imisebenzi eliyifa lawo.

Bezakhiwe steel elixutshiwe

Kaningi yokuthuthukisa ukucutshungulwa, izakhiwo ngokomzimba futhi amakhemikhali namandla ukungezwa ku steel izakhi ezihlukahlukene, okusho ukuthi doped. Ngokuvamile, ngalezi zinjongo, i-chromium, ne-nickel, manganese. Bezakhiwe izinga steel ingaqukatha eyodwa noma ezimbalwa izici eziningana ezinjengolwazi. Kule ndaba, sigqame:

• ingxubevange okuphansi (inani izithasiselo akuyona ezingaphezu kuka-2.5%).
• Srednelegirovannye (sibalo ongama-10%).
• elixutshiwe High (izakhi ezengeziwe akha ngaphezu kuka 10%).

Ukuze uqonde ukuthi ukusebenza okufakiwe, kubalulekile ukuba baqonde indlela yokwakheka into. Kusekelwe ferrite (mayelana 90% by volume). Izakhi alloying kuthiwa ziyoncibilika ferrite, kanjalo ngcono ukuqina yayo. Ikakhulukazi iphumelela kulokhu, i-silicon nickel kanye manganese. Kodwa i-chromium, i-tungsten kanye molybdenum nethonya buthaka.

Kufanele kuqashelwe ukuthi kwesakhiwo ingxubevange steel kuyahluka weldability ongaphakeme. Lokhu kungenxa ukuqina zone ukushisa abathintekayo kanye kumiswa ngaphakathi ke kwezakhiwo ukuthi zintekenteke. Ngakho-ke, amasu ezikhethekile asetshenziswa inqubo Welding, ithuthukiswe ngamunye kulolu hlobo of okuhlinza.

Okuphansi ingxubevange steel kwesakhiwo abaningi esetshenziswa ukwenziwa amakhanda, namakalishi futhi ipulazi imishini. Zonke mikhiqizo zinezikhathi ikhono lazo ukumelana imithwalo onhlobonhlobo. weldability imingcele yalesi steel Awunawo imikhawulo.

Kusukela ephezulu ingxubevange steel wenza lomshini bese ephendulwa rotors, sikhungo, amapayipi umusi amapayipi kanye manifolds.

Carbon Bezakhiwe Steel

Uhlobo lwesibili emelelwa izinhlobo ezimbalwa kakhulu, njenge:

• Engineering. Insimbi yesakhiwo yalolu hlobo isetshenziswa womshini izimoto.
• Automaton. Kungenxa yokuthi lokhu steel ukwenza iziqobosho ahlukahlukene. Kuyinto neze efanelekayo Welding, yonke imininingwane okwenziwa emishinini.
• Igumbi Boiler. Esisemqoka khona, lapho kuziwa womshini boilers lempahla ukumelana okushisa aphezulu. Lokhu kuhlinzwa has weldability ezinhle.

Insimbi yesakhiwo - indaba, ngaphandle lapho ukukhiqizwa kwezinhlobo ezithile izakhiwo kanye izingxenye akunakwenzeka.
