Rotor degassing graphite hal abuur leh ayaa kordhisa nolosha adeegga qalabka sifaynta dareeraha aluminium

Garaafyada garaafyada rotor, tuubada degassing, gaskets graphite, rotor graphite,

Shirkaddayadu waxay soo saartay anti-oxidationgaraafka rotor degassing ka samaysan garaafka saafiga ah ee sare ayaa soo jiitay dareenka baahsan ee suuqa. Therotor degassing ma aha oo kaliya inay si wax ku ool ah u wanaajiso saameynta nadiifinta ee dhalaalka aluminiumka, laakiin sidoo kale waxay si weyn u kordhisaa nolosha adeegga qalabka, taasoo keenaysa faa'iidooyin dhaqaale oo muhiim ah shirkadaha wax soo saarka aluminium.

Anti-oxidation-karotor degassing wuxuu ka samaysan yahay garaafyo nadiif ah oo sarreeya, tayada graphite waxay si toos ah u saameynaysaa cimriga rotor-ka. Iyada oo loo marayo tiknoolijiyada khaaska ah ee farsamaynta iyo codsiga daboolka ilaalinta anti-oxidation ee dusha sare, nolosha adeegga rotor-ka ayaa laga sii daayaa 30-ka maalmood ee dhaqanka ilaa 50-60 maalmood, si weyn u wanaajinaya waxtarka hawlgalka ee qalabka.

Ujeedada ugu weyn eerotor degassing waa in la nadiifiyo aluminium aluminium dareere ah. Habka nadiifinta ee aluminium aluminium dareere ah waa hab muhiim ah oo lagu hagaajinayo waxqabadka dhamaystiran ee aluminium aluminium. Habkan, arotor degassing waxaa loo isticmaalaa in lagu qaso gaaska sifaynta iyo dareeraha, ka dibna lagu afuufo aluminiumka dhalaalaysa iyada oo loo marayo habka duritaanka wareega. Tan waxaa loo arkaa inay tahay tignoolajiyada ugu horumarsan xilligan. Mabda'a shaqada eerotor degassing waxa uu ku salaysan yahay nidaam ka kooban rotor ul iyo nozzle, kaas oo u kala firdhiya argon ama nitrogen xumbo yaryar oo aan tiro lahayn oo xawli sare leh kuna kala firdhiya birta dhalaalaysa. Xumboyadani waxay nuugaan hydrogen iyo oksaydhyada dhalaalka iyada oo loo marayo mabaadi'da kala duwanaanshaha cadaadiska gaaska iyo xayeysiinta dusha sare, oo ugu dambeyntii ka soo saara dusha dhalaalka si loo gaaro nadiifinta.

Dhinaca isticmaalka iyo dayactirka, waxa loo baahan yahay in fiiro gaar ah loo yeesho qodobbada soo socda:

Dhuunta wareega eerotor degassing waxay ka samaysan tahay garaafka saafiga ah ee sarreeya, kaas oo loogu talagalay in lagu kala firdhiyo xumbo iyo isticmaalka xoogga centrifugal si siman loo isku daro socodka gaaska-dareeraha, taas oo kordhinaysa goobta xidhiidhka iyo wakhtiga u dhexeeya xumbo iyo dareeraha aluminium aluminium, iyo kor u qaadida saamaynta nadiifinta.

Ka dib habaynta, heerkulka sare u adkaystarotor degassing Waxay leedahay nolol adeeg 55-65 maalmood oo ah 700°C iyo 25-35 maalmood oo ah 1000°C. Codsiga daahan ilaalinta dusha sare waxay sii kordhinaysaa cimrigeeda adeeg ilaa 50-60 maalmood.

Si loo kordhiyo nolosha adeegga eerotor degassing, waxaa lagu talinayaa in aad horay u sii kululeyso 5-10 daqiiqo meel ku saabsan 100mm ka fog dusha dareeraha ka hor inta aan la gelin dareeraha aluminiumka si looga fogaado saameynta qaboojinta degdega ah ee alaabta. Gaaska waa in la soo bandhigaa ka hor inta aan rotor-ka la galin dareeraha, iyo sahayda gaaska waa in la joojiyaa ka dib marka rotorku ka baxo dusha dareeraha ah si looga hortago in sankaagu xirmo.

Sababta ugu weyn ee dhaawacarotor degassings waa oksaydhaynta heerkulka sare. Graphite waxa uu mari doonaa oksaydhdhismeed weyn oo hawada ah heerkul ka sarreeya 600°C, samaynta CO iyo CO2 gaasaska, taasoo keenaysa dhexroorka rotor inuu si tartiib tartiib ah hoos ugu dhaco ilaa uu jabo oo uu noqdo mid aan la isticmaali karin.

Iyadoo la wanaajinayo qalabka iyo farsamada farsamaynta eerotor degassing, Alaabtani waxay muujinaysaa waxqabad aad u fiican iyo faa'iidooyin dhaqaale oo ku saabsan nadiifinta dareeraha aluminium, calaamadaynta dhererka cusub ee tiknoolajiyada wax soo saarka aluminium. Shirkadaha wax soo saarka ee dooranaya noocaanrotor degassing kaliya ma hagaajin karo waxtarka wax soo saarka, laakiin sidoo kale si wax ku ool ah u dhimi karto kharashka dayactirka qalabka, taas oo u qalanta codsiga baahsan.
