Thaum peb paub txog cov ntsiab lus tseem ceeb thiab lwm yam khoom ntawm cov hlau alloy steel castings, peb tuaj yeem paub qee qhov ntawm nws cov haujlwm, zoo thiab lwm yam ntaub ntawv ntsig txog, uas tseem yuav pab tau rau kev siv tom qab. Dab tsi yog nws cov ntsiab lus alloying?
1. Lub ntsiab alloying ntawm alloy steel castings yog silicon, manganese, chromium, npib tsib xee, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, txhuas, tooj liab, boron, tsis tshua muaj ntiaj teb, thiab lwm yam ntawm lawv, vanadium, titanium. , niobium, zirconium, thiab lwm yam yog muaj zog carbide-forming ntsiab nyob rau hauv steel. Tsuav muaj cov pa roj carbon txaus, nyob rau hauv cov xwm txheej tsim nyog, lawv cov carbides tuaj yeem tsim tau.
2. Alloy steel castings nkag mus rau hauv cov khoom tov hauv atomic lub xeev thaum carbon tsis txaus los yog nyob rau hauv qhov kub thiab txias; manganese, chromium, tungsten thiab molybdenum yog carbide tsim cov ntsiab lus, qee qhov nkag mus rau hauv cov khoom siv hauv lub xeev atomic, thiab lwm qhov yog hloov pauv alloy infiltration Carbon lub cev; aluminium, tooj liab, npib tsib xee, cobalt, silicon, thiab lwm yam yog cov ntsiab lus uas tsis tsim carbides thiab feem ntau muaj nyob rau hauv cov kua hauv lub xeev atomic.
Nws tuaj yeem pom los ntawm cov lus qhia saum toj no tias muaj ntau cov ntsiab lus alloying nyob rau hauv alloy steel castings. Txawm hais tias lawv tsis yog cov ntsiab lus tseem ceeb, lawv yeej muaj txiaj ntsig zoo ntawm qhov zoo. Qee qhov ntawm nws cov khoom tuaj yeem hais tias muaj feem xyuam nrog cov ntsiab lus alloying.
