Ib qho ntawm qhov zoo ntawm cov hlau castings yog lawv cov qauv yooj yim. Cov neeg tsim qauv muaj kev ywj pheej siab tshaj plaws hauv kev xaiv cov duab thiab qhov loj ntawm cov casting, tshwj xeeb tshaj yog rau cov khoom uas muaj cov duab nyuaj thiab hollow cross-sections. Hlau castings tuaj yeem tsim tau siv cov txheej txheem tshwj xeeb ntawm cov tub ntxhais sib dhos. Lawv shaping thiab hloov kho yog yooj yim heev, thiab kev hloov dua siab tshiab los ntawm kev kos duab rau cov khoom tiav yog ceev heev, yooj yim cov lus teb ceev thiab luv luv lub sij hawm. Kev tsim kho kom zoo ntawm cov duab thiab qhov zoo, qhov kev ntxhov siab tsawg kawg nkaus, thiab qhov muaj zog tshaj plaws ntawm cov qauv kev ncaj ncees tag nrho qhia tau qhov yooj yim thiab cov txheej txheem zoo ntawm steel casting tsim.
Hlau castings muaj zog metallurgical adaptability thiab variability, tso cai rau kev xaiv ntawm txawv tshuaj compositions thiab microstructure tswj kom tau raws li ntau yam engineering yuav tsum tau. Cov cuab yeej siv tshuab thiab kev ua tau zoo tuaj yeem xaiv tau nyob rau hauv ntau yam los ntawm kev kho cua sov sib txawv, thiab lawv muaj cov weldability zoo thiab machinability.
Lub isotropic xwm ntawm cam khwb cia hlau cov ntaub ntawv thiab muaj zog zuag qhia tag nrho cov qauv kev ncaj ncees ntawm steel castings txhim kho engineering kev ntseeg tau. Ua ke nrog qhov zoo xws li qhov hnyav txo qhov tsim thiab lub sijhawm xa khoom luv, lawv muaj kev sib tw kom zoo dua ntawm cov nqi thiab kev lag luam.
Qhov hnyav ntawm steel castings tuaj yeem sib txawv ntawm ntau yam. Cov hlau me me tuaj yeem yog peev castings hnyav tsuas yog kaum grams, thaum cov hlau loj loj tuaj yeem hnyav ob peb tons, kaum ntawm tons, lossis ntau pua tons.
