Inoculant

Inoculant

Inoculant yog ib yam khoom uas txhawb nqa graphitization, txo qhov nyiam ntawm lub qhov ncauj dawb, txhim kho graphite morphology thiab kev faib tawm, nce tus naj npawb ntawm eutectic pawg thiab refines lub koom haum matrix. Nws muaj txiaj ntsig zoo hauv lub sijhawm luv luv (txog 5-8 feeb) tom qab kev kho mob inoculation. Ferro silicon inoculants thiab silicon barium inoculants yog ob hom inoculants.

Cov cuab yeej cuab tam ntawm grey cam khwb cia hlau nyob ntawm nws cov microstructure. Grey cam khwb cia hlau tsis muaj inoculation kev kho mob, microstructure instability, tsis tshua muaj neeg kho tshuab zog, castings ntawm nyias-walled yooj yim kom pom dawb lub qhov ncauj. Txhawm rau kom ntseeg tau qhov sib xws ntawm kev ua haujlwm zoo, kev kho gestation yog qhov tseem ceeb.

Inoculant siv nyob rau hauv cam khwb cia hlau inoculation kev kho mob, ntxiv ib tug me me ntawm inoculant, cov tshuaj muaj pes tsawg leeg ntawm cam khwb cia hlau muaj me ntsis cuam tshuam rau nws cov microstructure, tab sis qhov cuam tshuam loj heev, yog li txhim kho cov khoom ntawm grey cam khwb cia hlau, nws lub cev muaj zog kuj muaj. ib qho cuam tshuam loj. Kev kho kom zoo inoculation muaj cov teebmeem hauv qab no:

◆ Tshem tawm lossis txo qhov nyiam ntawm qhov ncauj dawb;
◆ zam qhov tshwm sim ntawm lub koom haum supercooling;
◆ Txo cov phab ntsa thickness rhiab heev ntawm cam khwb cia hlau qhov chaw, kom qhov sib txawv ntawm microstructure ntawm nyias thiab tuab seem ntawm castings yog me me, thiab qhov sib txawv ntawm hardness kuj yog me me;
◆ Txhawm rau txhawb cov nucleation ntawm eutectic masses, kom tus naj npawb ntawm eutectic masses nce;
◆ Ua cov graphite daim ntawv nyob rau hauv cam khwb cia hlau yog feem ntau zoo thiab uniformly faib A-hom graphite, thiaj li mus txhim kho lub mechanical zog ntawm cam khwb cia hlau.
Zoo-pregnated cam khwb cia hlau muaj zoo fluidity, txo shrinkage ntawm castings, txhim kho machinability thiab txo residual kev nyuaj siab.
