Cov nplaim txiav ntawm cov hlau yog ib qho pheej pheej yig, kev siv nyiaj hauv kev siv nyiaj. Kev ua haujlwm yuav tsum yog tus neeg teb xov tooj tsim nyog. Cov qauv yog siv hauv kev kho tshuab, tsis muaj hlau thiab hlau ua hlau thiab lwm yam lag luam.
Nws yog qhov tsim nyog
- - Lub tog raj kheej nrog cov pa thiab cov pa roj;
- - Zuag qhia tag nrho;
- - qhov ncauj;
- - hlau.
Cov Lus Qhia

Ua ntej tshaj, sov thaj chaw txiav rau qee qhov kub. Nco ntsoov tias tej zaum yuav muaj qhov sib txawv thaum tshav kub kub rau txhua hom hlau. Yeej, nws txawv ntawm 300 txog 1300 degrees. Cov txheej txheem ua ntej yuav cia qhov oxidation ntawm cov hlau hauv cov pa yuav tsum pib. Raws li qhov tshwm sim, nplaim taws ntawm acetylene lossis hloov roj cua tshwm. Tom qab ntawd, koj tuaj yeem tso rau hauv oxygen, uas txiav cov hlau thiab tam sim ntawd tshem tawm cov oxides. Nco ntsoov tias cov nplaim taws kub tsis tu ncua, rau qhov no nws yuav tsum yog nyob ntawm pem hauv ntej ntawm cov pa dej.

Thaum twg ua tau, xaiv cov pa roj carbon tsawg nrog cov ntsiab lus tshuaj ntawm tsis pub ntau dua 0.3%. Lawv yooj yim tshaj plaws rau kev txiav. Rau cov pa roj carbon monoxide siab, koj yuav tsum tau chaw so txiav nrog kev sib ntxiv ntawm cov fluxes tshwj xeeb.
Kauj ruam 3
Them sai rau cov nplaim taws, nws ntev yuav tsum ncaj qha nyob ntawm qhov tuab ntawm hlau. Yog li, ib qho khoom uas nws cov tuab tshaj li 400 hli yuav tsum tau txiav nrog cov nplaim hluav taws uas nkag mus rau qhov tob tob, muaj ntau ntawm acetylene. Txwv tsis pub, ib qho nplaim hluav taws xob tuaj yeem faib nrog.
Kauj ruam 4
Xaiv qhov xav tau txiav ceev raws qhov tuab ntawm cov hlau. Qhov loj dua nws yog, qhov ceev ceev yuav tsum muaj.
Kauj ruam 5
Teem cov kev taw qhia ntawm cov nplaim taws mus rau ntawm ntug heev ntawm cov hlau, nws yog qhov tseem ceeb heev kom xaiv lub kaum sab xis uas tsis yog los ntawm qhov pib. Ua kom cov nplaim hluav taws kub ntawm ntug ntawm cov hlau kom txog thaum koj mus txog qhov kub thiab txias tsis xav tau.
Kauj ruam 6
Ua raws li cov txheej txheem tshwj xeeb hlau txiav yog tias koj xav tau ua haujlwm rau hauv toj. Hauv qhov no, ua ntej tshav kub ntawm ntug ntawm cov khoom siv, tom qab ntawd tua lub nplaim taws thiab tsuas yog tom qab ntawd pib txiav kev txiav tawm oxygen. Qhib lub valve ntawm lub teeb maj mam qeeb, yog li ntawd cov pa oxygen yuav hlawv ntawm cov hlau molten ntawm nws tus kheej, thiab koj yuav zam rau lub nraub qaum ntawm cov nplaim taws, paj rwb.
Kauj Ruam 7
Ua tib zoo saib xyuas cov tuab ntawm cov hlau: yog tias nws tshaj 50 hli, khaws cov nplooj ntawv ntawm lub kaum ntse ntse, yog li koj tuaj yeem ua kom cov dej ntws ntawm cov slag formations thiab ua txoj haujlwm raws li muaj tseeb.
Kauj ruam 8
Xaiv lub qhov ncauj raws li cov tuab ntawm cov hlau: yog tias nws txawv ntawm 8-300 hli, koj yuav xav tau lub qhov ncauj uas muaj tus lej sab nraud ntawm 1 txog 5 thiab ib tus lej sab hauv ntawm 1 txog 2.
Kauj Ruam 9
Koj tuaj yeem ua kom raug txoj haujlwm ntawm kev txiav cov hlau, pib xaiv lub kaum sab xis tsis tsim nyog ntawm lub teeb thaum txiav, txiav txim siab qhov taw tes uas koj yuav pib txiav, tswj lub kaum sab xis ntawm cov nplaim hluav taws (tsis ntau tshaj 5 degrees ntawm kev txiav txim siab, nrog cov ntawv tuab ntawm hlau ntau dua 100 hli, qhov sib txawv ntawm 2-3 qib raug tso cai) los ntawm xaiv cov roj kom raug thiab qhov tseeb ntawm tus lej.
