Lub sijhawm ntev inoculant - yog ib qho inoculant nrog ntxiv anti-decomposition elium thiab strontium. Thaum lub sij hawm cov txheej txheem casting, nws yog tiag tiag silicon- barium inoculant. Lub barium lub caij tuaj yeem ua rau muaj kev cuam tshuam ntawm cov noob thiab nce tus nqi ntawm ferrite. Barium-muaj ferrosilicon tsis tsuas yog anti-rot cov khoom, tab sis kuj tseem ua tau zoo rau kev tiv thaiv dawb cam khwb. Ntev-kav cov khoom siv cov noob (silicon- barium noob ua los ntawm kev sib xyaw metalling meticon thiab cov hlau uas yuav tsum tau ua ntu zus thiab cov roj tawg. Nws yog kev ntxiv thaum lub sij hawm casting txheej txheem ntawm lub thawv. Nws txhawb nqa graphitization, txo cov nyiam rau dawb casting morpleology thiab faib cov pab pawg thiab txhim kho cov pawg ua haujlwm ntxiv. Nws muaj qhov cuam tshuam zoo tsis pub dhau lub sijhawm luv tom qab inoculation (li 5-8 feeb).
