ZG35CR24NI7SIN Norme: GB 8492-87 Bizalela mpe bonene ya bosaleli: Température ya bosaleli ya likolo ezali 1100 degré , makasi ya molunge ya likolo, résistance ya malamu ya oxydation.
ZG35Cr24Ni7SiN Refining process, process contains the molten steel package preparation electric arc furnace at the beginning of the package refining + package blowing ammonia gas, the use of the rich resources and cheap ammonia gas as raw materials, through the steel blow ammonia alloying, can greatly reduce the production cost of ammonia steel, through reasonable process to improve alloy recovery, solve the problem of chemical composition is not easy to control, improve the quality of molten steel Metallurgie na likambo ya kosala na yango.
ZG35Cr24Ni7SiN The lower limit of nickel component 7.00% and the lower limit of chromium composition 23.00% calculate the amount of nickel and chromium respectively, Add nickel plate and ferrochrome and ferrochrome nitrogen (add ferrochromium nitrogen at 0.3%), And add ferrochromium and ferronitride, Before adding iron nitride, the nitrogen at the bottom shall be replaced in Avance, pression ya gaz ya azote ya 2,5~3,5kg, débit, kobanda 45 kino 65 L/min, ferrochrome esengeli kobakisa na ba lots misato to minei, sala que ferrochrome ya liboso e fondu entièrement avant ya kosangisa batch ya suka, après jusqu’à 70%, échantillonnage mpo na analyse mobimba, ajuster le éléments d’ajouter;
ZG35Cr24Ni7SiN The smelting of nitrogen-containing high-alloy heat-resistant steel casting in the past was the smelting of electric arc furnace smelting, smelting, oxidation, reduction three stages, The smelting method has the following defects: (1), nitrogen alloying is generally in the smelting period of adding hydrogenation alloy (such as nitrogen iron, nitric iron nitride) to achieve Ebende ya azote, nitrure ya manganèse ya monene ya mbindo ezali mingi, mai ya bibende oyo ebebisami; (2) Na ntina na mbuma moke ya azote ntango alliage hydrogéné ezali ntalo mingi, ntalo ya biloko oyo batyá na fulu ezali mingi mpenza; (3) Ezali mpasi mpo na kopekisa biloko oyo esalemi na biloko ya chimique, ezali mpasi te mpo na kobimisa carbone, azote mpe biloko mosusu oyo esalaka na molɔngɔ te; (4) bosenga monene ya alliage ya chrome mpe taux ya récupération instable ezali pete mpo na kobimisa bosoto; (5), procédé ya fondue mpe ya oxydation oyo ezali kopumbwa na kati ya oxygène mingi oyo esali ete oxygène ezala mingi na acier fondu, inclusion ya likolo mpe gaz ya surface ya coulée ezali facile ya kobimisa taux ya déchets ya stoma ya likolo; (6) Viscosité ya mayi ya likolo ya bibende oyo esili ko fondu, ezali pete te mpo na kosopa.
