Qhov ua tau zoo ntawm qhov nrawm pauv-nozzle yog siab

Kev hloov pauv sai nozzle muaj ntau daim ntawv thov nyob rau hauv cov txheej txheem ntawm kev tsim khoom lag luam thiab ntau lawm, uas coj tau ntau yam kev yooj yim rau cov txheej txheem kev lag luam. Nrog cov kev nruam ntej ntawm kev tsim kho steel hlau, daim teb ntawm kev thov ntawm lub nrawm-hloov nozzle tseem tau txais loj dua thiab loj dua. Qee qhov xwm txheej, kom ua tiav cov xwm txheej no, kev ua haujlwm ntawm kev ua haujlwm thiab cov khoom zoo yuav tau ua kom zoo dua, raws li hauv qab no:

1. Thaum ua haujlwm, tus nqi ntws yuav tsum raug tswj kom thiaj li tsis muaj teeb meem zoo thaum lub sijhawm ua haujlwm;

2. Lub chaw iav muag kuj tseem yog ib qho tseem ceeb ntawm kev ua haujlwm. Feem ntau, cov hlau molten xav tau kev pab tusyees faib, thiab nws yuav tsum ntws qeeb;

3. Lub nrawm ntawm kev saib xyuas slag melting kuj yog ib qho tseem ceeb hauv lub sijhawm, yog li nws yuav tsum tswj tau zoo;

4. Tsis muaj teeb meem ntau npaum li cas, nws tsis yooj yim sua kom lub cuab yeej ua tsis yooj yim thaum nws siv;

5. Lub hlau molten nchuav rau hauv cov neeg siv dag zog yuav tsum tau sau tseg tias yuav tsum tsis txhob muaj kev sib cav sib ceg;

6. Thaum ua haujlwm, yuav muaj qee qhov tsis txaus ntseeg. Thaum siv, ceev faj kom tsis txhob tshwm sim qhov tshwm sim ntawm slag.
