Cov ntsiab lus tseem ceeb ntawm cov txheej txheem tswj thaum smelting cam khwb cia hlau nyob rau hauv induction melting rauv

Cov ntsiab lus tseem ceeb ntawm kev tswj cov txheej txheem thaum pom zoo siv induction melting rauv rau smelt cam khwb cia hlau yog raws li nram no:

1. Tus nqi ntawm npua hlau ingots nyob rau hauv tus nqi yuav tsum tsis txhob ntau tshaj 20%, nyiam dua nyob ib ncig ntawm 10%;

2. Nyob rau hauv lub recarburizer ntxiv nrog tus nqi, nws yog qhov zoo tshaj kom muaj ib qho kev faib ua feem (40-55%) ntawm metallurgical silicon carbide;

3. Ua tib zoo ua tiav cov kev kho mob inoculation thaum lub sij hawm hlau tapping, thiab xaiv cov inoculants tsim nyog raws li cov kev tsim khoom tshwj xeeb ntawm lub tuam txhab. Tus nqi ntawm inoculants ntxiv yuav tsum yog 0.1-0.2% siab dua li thaum lub sij hawm cupola smelting. Qhov zoo tshaj plaws yuav tsum xeem dhau qhov kev ntsuam xyuas teb. Tseeb;

4. Yuav tsum tau incubated instantaneously thaum lub sij hawm pouring txheej txheem;

5. Thaum tsim cov castings nrog cov kev xav tau zoo, metallurgical silicon carbide yuav tsum tau muab ntxiv rau hauv qhov cub rau pretreatment ua ntej tapping.
