Zoo heev Argon Gas

Argon yog ib qho tsis muaj xim, tsis muaj ntxhiab tsw monatomic gas. Qhov ntom ntawm argon yog 1.4 npaug ntawm huab cua thiab 10 npaug ntawm helium. Argon yog ib qho roj inert uas tsis hnov ​​​​mob nrog lwm yam tshuaj nyob rau hauv chav tsev kub thiab tsis yaj nyob rau hauv cov kua hlau ntawm qhov kub thiab txias. Nws tuaj yeem qhia nws qhov zoo tshaj plaws thaum vuam cov hlau tsis muaj hlau. Nws tuaj yeem siv rau qhov muag teeb thiab arc vuam ntawm stainless hlau, magnesium, txhuas, thiab lwm yam, uas yog, "argon arc vuam".
Argon yog cov roj tsawg uas siv dav hauv kev lag luam. Nws yog inactive heev nyob rau hauv cov xwm thiab tsis muaj peev xwm hlawv los yog txhawb combustion. Nyob rau hauv lub dav hlau tsim, shipbuilding, atomic zog kev lag luam thiab machinery kev lag luam sectors, thaum welding tshwj xeeb hlau xws li txhuas, magnesium, tooj liab thiab lawv alloys thiab stainless hlau, argon yog feem ntau siv raws li ib tug vuam shielding roj los tiv thaiv cov welded qhov chaw los ntawm oxidized. los yog nitrided los ntawm huab cua.
① Aluminium kev lag luam. Siv los hloov huab cua los yog nitrogen los tsim ib qho chaw inert thaum lub sij hawm tsim cov txheej txheem txhuas; los pab tshem tawm cov tsis xav tau soluble gases thaum lub sij hawm degassing; thiab tshem tawm cov yaj hydrogen thiab lwm yam khoom los ntawm molten aluminium.
②Steelmaking. Siv los hloov cov pa roj lossis vapor thiab tiv thaiv oxidation hauv cov txheej txheem; siv los do molten steel kom muaj qhov kub thiab txias tsis tu ncua; pab tshem tawm pliaj tsis soluble gases thaum lub sij hawm degassing; Raws li cov cab kuj roj, argon tuaj yeem siv los ua txheej txheej tshuaj ntsuam xyuas los txiav txim qhov muaj pes tsawg leeg ntawm cov qauv; argon kuj tuaj yeem siv rau hauv cov txheej txheem argon oxygen decarburization (AOD) siv hauv stainless hlau refining kom tshem tawm cov pa roj carbon monoxide thiab txo qhov poob ntawm chromium.
③ Hlau ua. Argon yog siv los ua inert shielding gas hauv vuam; muab kev tiv thaiv oxygen- thiab nitrogen-dawb nyob rau hauv annealing thiab dov ntawm hlau thiab alloys; thiab yaug cov hlau molten kom tshem tawm cov pores hauv castings.
④ Welding shielding gas. Argon ua hauj lwm pab raws li ib tug tiv thaiv roj thaum lub sij hawm vuam txheej txheem, uas muaj peev xwm zam lub burning poob ntawm alloy ntsiab thiab lwm yam welding defects tshwm sim los ntawm nws, yog li ua rau metallurgical cov tshuaj tiv thaiv thaum lub sij hawm vuam txheej txheem yooj yim thiab yooj yim rau kev tswj kom zoo zoo vuam. Los ntawm kev ua lub laser remelting xeem ntawm HT250 grey cam khwb cia hlau, tiam mechanism ntawm pores nyob rau hauv lub remelting cheeb tsam ntawm tus qauv nyob rau hauv txawv huab cua tiv thaiv tej yam kev mob tau kawm. Cov txiaj ntsig kev tshawb fawb pom tau tias nyob rau hauv kev tiv thaiv argon, cov pores hauv thaj tsam remelting yog nag lossis daus pores; Nyob rau hauv qhib tej yam kev mob, lub pores nyob rau hauv lub remelting cheeb tsam yog nag lossis daus pores thiab reactive pores.
⑤ Lwm yam kev siv. Electronics, teeb pom kev zoo, argon gas riam, thiab lwm yam.
