Classification ya ba aciers oyo ezo résister na chaleur .

Classification na contenus ya élément ya alliage .
1) Acier à bas carbone : Na kati ya acier ya boye ezali na to ezali rarement na ba éléments alliés mosusu, teneur ya carbone na yango ezali généralement koleka 0,2% te.
2) Acier à faible alliage Acier résistants : Na lolenge oyo ya acier ezali na élément allié moko to ebele, kasi contenus ezali likolo te, quantité totale ya ba éléments alliés oyo ezali na kati ya acier général eleki 5% te, contenus ya carbone eleki 0,2% te.
3) Acier à haute alliage résistants à chaleur : Na lolenge oyo ya acier, ezali na ba éléments alliés ebele, mpe teneur ya élément allié ezali généralement plus de 10%, ou même jusqu’à plus de 30%.
Classification selon ba caractéristiques ya acier .
1) Acier anti-oxydation (to acier non peeling résistant na chaleur) : Lolenge oyo ya acier ezali na résistance ya oxydation ya malamu mpe résistance ya corrosion ya température makasi na température ya likolo (en général 550 ~ 1200 degrés ), mpe ezali na makasi ya température ya likolo. Esalemaka mpo na kosala ba pièces ya four à chauffage ya ndenge na ndenge mpe ba échangeurs ya chaleur, kosala combustion ya turbine ya chaleur, concombres ya chaudière, plaque ya four ya four à chauffage mpe table à rouleaux mpe tube ya four. Résistance ya oxydation ezali indicateur principal, mpe ba composants yango moko ezo porter pression mingi te.
2) Acier ya force ya chaleur : na température ya likolo (mingi mingi 450 ~ 900 degrés C) ekoki ko supporter stress supplémentaire ya monene mpe kozala na résistance ya oxydation ya malamu mpe résistance ya corrosion ya gaz ya température makasi, mpe mingi mingi esengaka stress variable périodique. Esalemaka mingi mingi lokola rotor mpe lame ya turbine ya vapeur mpe turbine ya gaz, superchauffeur ya chaudière, boulon mpe ressort oyo ezali kosala na température ya likolo, na valve ya intake mpe ya échappement ya moteur ya combustion interne, réacteur ya hydrogénation ya pétrole, etc.
Classification na usage principal ya acier .
Heat-resistant steel for industrial furnaces: In addition to reactors, power station boilers, petrochemical industrial furnaces, in metallurgy, machinery, building materials, light industry and other industries, widely used as heat exchangers, heating furnace tubes, reflection tanks and other furnace in a variety of heat-resistant parts, in addition to the use of plates, tubes, rods and other heat-resistant steel deformation materials, and a large number of heat-resistant steel Ba castings. Ba couvercles ya four ya recuit ndenge na ndenge na ba usines métallurgiques, ba réservoirs ya muffle, ba tubes ya radiation, ba cadres ya chargement, ba ceintures ya chaîne, etc ya atmosphère contrôlée ba fours à chauffage continu, ezali mingi mingi 310 (0CR25NI20) to 3CR24NI7SINRE, 2CR25NI13 acier mpe bongo. Motango monene ya ba rouleaux ya nse mpe ba tubes ya radiation na ba fours ya chauffage continu mpe ba fours ya traitement ya chaleur na ba plantes métallurgiques ezali mpe ba tubes ya cast centrifuge ya acier résistant na chaleur ya alliage ya likolo. The commonly used brands are 0Cr18Ni9, 00Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 00Cr17Ni12Mo2, 3Cr24Ni7SiNRe, 0Cr23Ni13, 1Cr20Ni14, Cr25Ni20Si2, 00Cr10Ni20M O6CU6, 4CR25NI35NBW, 70crmovbre, 4CR28NI48W5SI2, 3CR26NI4MNORE, etc. Na industrie ya ciment, motango monene ya ba pièces ya acier résistantes, lokola 3cr24ni7sinre, 1cr20ni14.cr2014.cr2014.cr20, crcri14.cr20, crCR2. Na ceinture ya pré-chauffage ya ciment ya ciment humide, plaque ya grille mpo na refroidisseur ya grate ya grand ciment ya ciment, mpe seau ya matériel mpo na machine ya refroidissement .
