Kev siv tseem ceeb ntawm cov hlau tsis tshua muaj hauv ntiaj teb

Cov hlau tsis tshua muaj hauv ntiaj teb thiab lawv cov alloys ua lub luag haujlwm hauv deoxidation thiab desulfurization hauv steelmaking, txo lawv cov ntsiab lus mus rau hauv qab {{0}}.001% thiab hloov cov morphology ntawm inclusions, refining grain loj, yog li txhim kho cov kev ua tau zoo ntawm steel, txhim khu lub zog, toughness, corrosion kuj, thiab oxidation kuj. Cov hlau tsis tshua muaj hauv ntiaj teb thiab lawv cov alloys yog siv los tsim cov hlau tsis muaj zog, lub zog siab grey cam khwb cia hlau, thiab cov hlau cam creep, uas tuaj yeem hloov cov morphology ntawm graphite hauv cam khwb cia hlau, txhim kho cov txheej txheem casting, thiab txhim kho cov khoom ntawm cov hlau cam khwb cia (alloy. steel, cam khwb cia hlau). Ntxiv ib qho me me ntawm cov hlau tsis tshua muaj hauv ntiaj teb nyob rau hauv smelting ntawm bronze thiab tooj dag tuaj yeem txhim kho lub zog, elongation, kub tsis kam, thiab conductivity ntawm cov hlau. Ntxiv 1-1.5% cov hlau tsis tshua muaj hauv ntiaj teb rau cam khwb cia txhuas silicon alloys tuaj yeem txhim kho qhov kub thiab txias. Ntxiv cov hlau tsis tshua muaj hauv ntiaj teb rau aluminium alloy xov hlau tuaj yeem txhim kho lub zog tensile thiab corrosion kuj. Ntxiv 0.3% cov hlau tsis tshua muaj hauv ntiaj teb rau Fe Cr Al hluav taws xob cua sov alloys tuaj yeem txhim kho lawv cov oxidation tsis kam, nce lawv cov hluav taws xob tiv thaiv, thiab txhim kho lawv lub zog kub. Ntxiv cov hlau tsis tshua muaj hauv ntiaj teb rau titanium thiab nws cov alloys tuaj yeem txhim kho cov qoob loo loj, txo tus nqi nkag, thiab txhim kho qhov kub thiab txias corrosion.
