Kev vuamsib xyaw ua ke tiv thaiv rojyog tsim los txhim kho qhov zoo ntawm cov vuam. Cov roj uas xav tau rau cov roj sib xyaw kuj yog cov roj tiv thaiv vuam xws licov pa oxygen, cov pa roj carbon dioxide, argon, thiab lwm yam. Siv cov roj sib xyaw es tsis txhob siv cov roj ib leeg rau kev tiv thaiv vuam muaj qhov zoo ntawm kev ua kom cov dej ntws zoo, txhawb kev vuam du, txhim kho kev tsim, thiab txo qhov ceev ntawm cov qhov hws, thiab nrov heev hauv kev vuam, txiav thiab lwm yam lag luam.

Tam sim no, cov khoom siv feem ntau sivcov pa roj sib xyawtuaj yeem muab faib ua cov pa roj sib xyaw binary thiab cov pa roj sib xyaw ternary raws li hom pa roj sib xyaw.

Qhov ratio ntawm txhua yam khoom hauv txhua homroj sib xyawtuaj yeem sib txawv ntawm ntau yam, uas feem ntau yog txiav txim siab los ntawm ntau yam xws li cov txheej txheem vuam, cov khoom siv vuam, cov qauv hlau vuam, thiab lwm yam. Feem ntau hais lus, qhov siab dua qhov yuav tsum tau ua rau qhov zoo ntawm vuam, qhov siab dua qhov kev xav tau ntawm kev huv rau cov roj ib leeg siv los npaj covroj sib xyaw.

Ob Lub Cheebtsam Sib Xyaws Roj

Argon + Pa

Ntxiv ib qho nyiaj tsim nyog ntawmcov pa oxygenrau argon tuaj yeem txhim kho qhov ruaj khov ntawm lub arc thiab ua kom cov dej ntws zoo. Cov khoom txhawb nqa oxygen tuaj yeem ua rau cov hlau kub hauv lub pas dej molten nce, txhawb cov hlau ntws, txo cov qhov tsis zoo ntawm kev vuam, ua rau qhov vuam du, thiab ua kom qhov vuam ceev thiab txhim kho kev vuam zoo. Tsis tas li ntawd, cov pa oxygen + argon tiv thaiv muaj ntau yam kev siv thiab tuaj yeem siv rau kev vuam cov hlau carbon, cov hlau tsis tshua muaj hlau thiab cov hlau tsis xeb ntawm ntau yam tuab.

Argon + Carbon Dioxide

Cov pa roj carbon dioxide tuaj yeem txhim kho lub zog vuam thiab kev tiv thaiv xeb, tab sis cov pa roj carbon dioxide tiv thaiv ntshiab txau ntau dhau, uas tsis zoo rau cov neeg ua haujlwm ua haujlwm. Kev sib xyaw nrog argon ruaj khov tuaj yeem txo qhov nrawm ntawm cov hlau txau. Kev siv cov pa roj oxygen + argon tiv thaiv sib txawv muaj qhov zoo rau kev vuam cov hlau carbon thiab cov hlau tsis xeb.

Argon + Hydrogen

Hydrogenyog cov roj uas txo qhov kub thiab txias uas tsis yog tsuas yog ua rau kub ntawm arc xwb, ua kom vuam ceev dua, thiab tiv thaiv kev txiav tsis zoo, tab sis kuj txo qhov muaj feem yuav muaj CO2 pores thiab tiv thaiv kev puas tsuaj ntawm kev vuam. Nws muaj cov txiaj ntsig zoo heev rau kev vuam ntawm cov hlau nickel, cov hlau nickel-tooj ​​liab, thiab cov hlau tsis xeb.

Peb Lub Cheebtsam Sib Xyaws Roj

Argon + Pa + Carbon Dioxide

Qhov no yog cov roj sib xyaw peb yam uas siv dav tshaj plaws, uas muaj cov txiaj ntsig tiv thaiv ua ke ntawm ob yam roj sib xyaw saum toj no.Cov pa oxygenpab kom kub hnyiab, tuaj yeem ua kom cov dej yaj zoo, txhim kho qhov zoo ntawm kev vuam thiab kev vuam ceev; carbon dioxide tuaj yeem txhim kho lub zog vuam thiab kev tiv thaiv xeb, thiab argon tuaj yeem txo qhov tawg. Rau kev vuam cov hlau carbon, cov hlau tsis sib xyaw thiab cov hlau tsis xeb, cov roj sib xyaw no muaj cov txiaj ntsig zoo tshaj plaws.

Argon + Helium + Carbon Dioxide

Heliumtuaj yeem ua rau muaj zog cua sov ntau ntxiv, txhim kho cov dej ntws ntawm cov pas dej thiab txhawb kev tsim cov vuam. Txawm li cas los xij, vim tias helium yog cov roj inert, nws tsis muaj kev cuam tshuam rau kev oxidation thiab kev hlawv hlau ntawm cov hlau vuam. Yog li ntawd, nws tuaj yeem siv rau cov hlau carbon thiab cov hlau tsis tshua muaj hlau pulse jet arc vuam, cov hlau muaj zog siab, tshwj xeeb tshaj yog txhua qhov chaw luv luv hloov pauv vuam, thiab cov hlau tsis xeb txhua qhov chaw luv luv arc vuam los ntawm kev kho qhov sib txawv.
