Dab tsi yog alloy steel casting

Cov hlau alloy siv nyob rau hauv lub xeev casting tseem hu ua cam khwb cia hlau hlau. Alloy cam khwb cia hlau yog muab faib ua cam khwb cia hlau structural steel thiab tshwj xeeb-lub hom phiaj alloy cam khwb cia hlau raws li nws siv. Lub qub yog qis thiab nruab nrab alloy cam khwb cia hlau, uas yog tsuas yog siv los ua cov khoom siv dav dav. Cov tom kawg yog feem ntau siab alloy cam khwb cia hlau, xws li hnav-resistant cam khwb cia hlau, xeb thiab acid resistant cam khwb cia hlau, tshav kub-resistant cam khwb cia hlau, cam khwb cia hlau cuab tam steel, thiab lwm yam.

Casting zog ntawm cov cam khwb cia hlau structural steel thiab tshwj xeeb uas tsis muaj alloy cam khwb cia hlau yog zoo ib yam li cov carbon cam khwb cia hlau. Chromium thiab molybdenum nyob rau hauv steel txo lub fluidity ntawm molten hlau. tooj liab, manganese thiab npib tsib xee txhim kho fluidity. Volume shrinkage ntawm cov hlau yog feem ntau cuam tshuam nrog cov ntsiab lus carbon. Qhov siab dua cov ntsiab lus carbon, qhov loj dua qhov shrinkage, thiab qhov me me ntawm cov ntsiab lus alloying ntawm nws. Manganese thiab cov ntsiab lus refining siv lead ua qauv xws li vanadium, titanium thiab zirconium tuaj yeem txo qhov kub kub tawg, thaum chromium thiab molybdenum tuaj yeem ua rau kub kub tawg. Cov ntsiab lus alloy txo cov thermal conductivity thiab ua rau kom muaj kev ntxhov siab, uas ua rau kom muaj qhov txias txias ntawm cov hlau castings, tshwj xeeb tshaj yog rau cov hlau uas muaj manganese, chromium, molybdenum thiab lwm yam khoom.
