ZG35Cr24Ni7Si7Si7SìN7SìNSiN: GB 8492-87 e nascosa de aplicasion: ła tenperadura pi alta ła xe de 1100 gradi , a alta forsa de tenperadura, bona resistensa.
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 Ła conpoxision no ła xe façiłe da controłar, mejorare ła quałità de ła metalurgia de aciaio.
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 advance, Nitrogen gas pressure of 2.5~3.5kg, Flow rate, ranging from 45 to 65 L/min, Ferrochrome has to be added in three to four batches, Make sure the first ferrochrome melts completely before joining the latter batch, After up to 70%, Sampling for the full analysis, Regoła ła altre parte dełe ełementasion dełe regołe ałe spesifeghe secondo i risultati de canpionamento;
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 el periodo smeltente de aggiungere idrogene agliate (come nitride de fero azoto, nitride de fero) per raggiungere al ferro de azoto, nitride de manganese generale inpotente xe alto, liquido de acciaio in acciaio Polutato; (2) Par via al basso rendino de azoto quando l'allega idrogenata xe cara, El costo de le leghe smelenti xe molto alto; (3) conposision chimica xe difisiłe controłar, façiłe a far carbon, azoto e altri conponenti fora de linea; (4) El gran domanda de l'allea de cròmio e de recupero inpresabile xe facile da provocar sprechi; (5), de fondente e del proceso de osidasion che ła soffia in un mucio de osigeno che ła vien in alto osigeno contegnùo de aciaio in osigeno, inclusion Alta e contente de gas de ła superfisie de ła catura ła xe façiłe da produr l'alto taso de sprecamento de stoma; (6) Alta viscosità de aqua de aciaio fusile, No facile da verzer.
