Chii chinonzi nitrogen yemukati mesimbi yakanyungudutswa nechoto chekunyungudutsa?

Kana yakanyungudutswa mubhokisi, iyo nitrogen yemukati mune grey cast iron inowanzo 0.004 ~ 0.007%.

Cast iron ine shoma shoma yenitrogen, iyo inogona kusimudzira pearlite uye kubatsira kuvandudza ma mechanic properties ye cast iron. Kana iyo nitrogen yemukati iri pamusoro pe0.01%, kukanda kunowanzo kune nitrogen-induced pores.

Kazhinji, iyo nitrogen yemukati mune zvimedu simbi yakakwira zvakanyanya kupfuura iri musimbi yakakandwa. Pakunyungudutsa simbi yakakandwa mu an kudonhedzwa kunyorera vira, sezvo paine mashoma akakandwa simbi ingots uye zvakawanda zvimedu simbi inoshandiswa mukuchaja, iyo nitrogen yemukati musimbi yakakandwa inogadzirwa nekunyungudutsa ichave yakakwira zvinoenderana. high. Pamusoro pezvo, nekuda kwehukuru hukuru hwesimbi yakarashwa inoshandiswa mukuchaja, marecarburizer anofanirwa kushandiswa, uye mazhinji evagadziri vane yakakwira nitrogen yemukati, inova chimwe chinhu chinoita kuti nitrogen yemukati musimbi yakakandwa iwedzere.

Naizvozvo, kana yakanyungudutswa muchoto chinonyunguduka, iyo nitrogen yemukati musimbi yakakandwa yakakwirira kupfuura iri mucupola. Kazhinji kutaura, kana huwandu hwesimbi yakaraswa muchoto chemoto iri 15%, iyo nitrogen yemukati musimbi yakakandwa inenge 0.003 ~ 0.005%; apo huwandu hwesimbi yakarashika huri 50%, iyo nitrogen content inogona kusvika 0.008 ~ 0.012%; kana kubhadharisa zvese zvimedu zvesimbi, iyo nitrogen yemukati inogona kunge yakakwira se0.014% kana kupfuura.
