Kev cuam tshuam ntawm Foundry xuab zeb rau hlau nkag tau tsim rau Malleable Hlau Yeeb Fittings

Cov hlau nkag hauv zos tsim los ntawm malleable cam khwb cia hlau yeeb nkab fittings yog ib qho nyuaj rau to taub vim hais tias nws tshwm nyob rau sab saum toj ntawm cov yeeb nkab fittings qhov twg txawm tias foundry xuab zeb yog packed feem ntau densely cov hlau nkag mus tob rau hauv zoo inter-granular kab noj hniav nyob rau hauv cov xuab zeb pwm. Txhawm rau kawm txog cov txheej txheem ntawm kev nkag mus hauv zos cov pwm-hlau interface tau pom nyob rau hauv lub tshuab ntsuas metallographic thiab X-ray microanalyser, thiab kev nkag mus tau raug tshawb xyuas.Iron oxide uas muaj SiO2 thiab MnO yog pom ntawm pwm-hlau interface ntawm lub nkag mus thiab muaj ib co kab ntawm cov hmoov av ntawm pwm xuab zeb fusing thaum lub sij hawm pouring ze ntawm pwm-hlau interface. Xuab zeb pwm sib xyaw nrog ntau cov xuab zeb tshiab muaj txiaj ntsig zoo hauv kev txo cov kev nkag mus. Kev nkag mus tsis tuaj yeem tiv thaiv los ntawm kev siv zircon xuab zeb thiab chromite xuab zeb, txawm hais tias cov xuab zeb no muaj txiaj ntsig zoo rau kev nkag mus ntawm cov hlau castings. Cov plua plav ntawm pwm xuab zeb uas nce los ntawm kev rov siv dua fuses yooj yim piv rau bentonite thiab tshauv ntawm hiav txwv thee. Nws fuses ntawm kub hauv qab 1,100 degree.
