Pav Ca Yuav Luag Ntawm Qhov Kev Siv Qee Yam

Tus npua hlau rau steelmaking tau muab tso rau hauv qhov cub ua kom zoo nkauj thiab smelted raws li ib txoj kev ua kom tau txais hlau. Cov khoom lag luam hlau suav nrog cov hlau tsis sib xyaw, tiaj tiaj nruam cov yeeb yaj kiab thiab cov khoom siv ncaj qha cuam rau ntau yam steel castings. Feem ntau hais lus, hlau feem ntau hais txog steel dov mus rau ntau yam hlau. Hlau belongs rau cov hlau tsis zoo tab sis cov hlau tsis haum rau ferrous hlau.

Cov xim tsis muaj hlau, tseem hu ua cov hlau tsis huv, hais txog cov hlau thiab alloys lwm yam tsis muaj hlau, xws li tooj liab, tin, txhuas, zinc, txhuas, tooj daj, tooj daj, tooj txhuas, txhuas tiaj, thiab cov kabmob alloys. Ntxiv rau, chromium, npib tsib xee, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, ca bar thiab lwm yam tseem siv hauv kev lag luam. Cov hlau no tsuas yog siv los ua cov hlau txuas ntxiv txhawm rau txhim kho cov yam ntxwv ntawm cov hlau. Ntawm lawv, tungsten, titanium, molybdenum, ca bar thiab lwm yam feem ntau yog siv los tsim cov cuab yeej. Ntawm cemented carbide. Cov hlau tsis muaj hlau hu ua kev lag luam hlau, ca bar ntxiv rau cov khoom muaj nqi: platinum, gold, silver thiab lwm yam hlau tsis tshua muaj, suav nrog cov xov tooj cua uranium thiab radium.

Hlau yog hlau-carbon alloy nrog cov ntsiab lus carbon ntawm 0.04% -2.3%. Txhawm rau kom ntseeg tau nws cov tawv thiab yas, cov ntsiab lus carbon dav dav tsis ntau tshaj li 1.7%. Ntxiv nrog rau hlau thiab carbon, ca bar lub ntsiab ntawm cov hlau muaj xws li silicon, manganese, sulfur, ca bar thiab phosphorus. Muaj ntau txoj hauv kev los cais hlau.
