Hlau yog ib yam khoom tseem ceeb heev rau cov hniav ntawm chav tsev thiab roj turbine. Cov hlau no xav tau cov cuab yeej siv siab, siab zog thiab ua haujlwm siab kom ua haujlwm tau zoo nyob rau hauv cov xwm txheej hnyav. Cov hauv qab no yog cov khoom sib txawv ntawm cov hlau siv hauv chav tsev thiab roj turbine.
1. Cov hlau kub kub: Cov hlau no tsim nyog rau cov hniav nyob rau hauv qhov kub thiab txias thiab feem ntau tuaj yeem tiv taus qhov kub txog li 650 degree C. Cov hlau no yuav tsum muaj kev tiv thaiv corrosion zoo, oxidation tsis kam thiab siab zog.
2. Stainless hlau: Cov hlau no zoo heev corrosion thiab hnav tsis kam. Vim tias lawv cov corrosion kuj zoo thiab cov khoom kub, lawv zoo haum raws li cov ntaub ntawv hniav rau chav tsev thiab roj turbine.
3. High alloy steel: Cov hlau no yog cov khoom siv uas muaj zog heev thiab ua haujlwm ntev. Lawv feem ntau siv rau ntawm cov hniav nyob rau hauv qhov kub thiab txias, thiab tuaj yeem tiv taus corrosion thiab qaug zog.
4. Cam khwb cia hlau: Cov hlau no zoo heev rau cov turbine loj. Txoj kev casting tuaj yeem tsim cov hniav loj thiab tuaj yeem hloov mus rau ntau yam qauv tsim.
