Ib tug tswv alloy yog lub hauv paus hlau xws li txhuas, magnesium, npib tsib xee, los yog tooj liab ua ke nrog cov feem pua siab sib piv ntawm ib lossis ob lub ntsiab lus. Nws yog tsim los siv los ua raw cov ntaub ntawv los ntawm kev lag luam hlau, thiab yog li ntawd peb hu ua master alloy los yog raws li alloy semi-tiav khoom. Master alloys yog tsim nyob rau hauv ntau yam duab xws li ingot, waffle daim hlau, rods nyob rau hauv coils thiab lwm yam.
1. Dab tsi yog tus tswv alloys?
Tus tswv alloy yog cov khoom siv hlau uas siv rau casting nrog cov muaj pes tsawg leeg los ntawm kev ua kom zoo, yog li tus tswv alloy tseem hu ua casting master alloy. Qhov laj thawj yog vim li cas tus tswv alloy hu ua "master alloy" yog vim nws muaj zog genetic zog raws li lub hauv paus khoom ntawm casting, uas yog hais tias, ntau yam ntxwv ntawm tus tswv alloy (xws li carbide faib, grain loj, microscopic daim iav duab qauv. ), Txawm hais tias suav nrog cov khoom siv kho tshuab thiab ntau lwm yam ntxwv uas cuam tshuam rau qhov zoo ntawm cov khoom siv casting) yuav tau txais txiaj ntsig rau castings tom qab remelting thiab pouring. Cov ntaub ntawv siv dav dav siv cov khoom siv zoo xws li kub-kub alloy master alloys, kub-resistant steel master alloys, dual-theem master alloys, thiab cov pa stainless hlau master alloys.
2. Master Alloys Daim Ntawv Thov
Muaj ntau ntau qhov laj thawj rau kev ntxiv cov master alloys rau yaj. Ib daim ntawv thov tseem ceeb yog kev hloov kho muaj pes tsawg leeg, piv txwv li hloov cov khoom sib xyaw ntawm cov kua hlau kom paub txog cov tshuaj tshwj xeeb. Lwm daim ntawv thov tseem ceeb yog kev tswj cov qauv - cuam tshuam lub microstructure ntawm hlau hauv cov txheej txheem casting thiab solidification thiaj li hloov nws cov khoom. Xws li cov khoom muaj xws li txhua yam muaj zog, ductility, hluav taws xob conductivity, castability, los yog deg tsos. suav ntawm nws daim ntawv thov, tus tswv alloy feem ntau kuj hais tias yog "hardener", "grain refiner" lossis "modifier".
