Muaj zog oxide-forming ntsiab, txhuas, silicon, thiab manganeseyog cov deoxidizers feem ntau siv hauv cov hlau tsim.

Deoxidizer siv rau dab tsi?

A deoxidizer yog ib qho chaw siv hauv cov tshuaj tiv thaiv kom tshem tawm cov pa oxygenCov khoom no muaj ib lossis ntau lub ntsiab lus uas yog scavengers rau oxygen txo qhov muaj cov pa yaj hauv cov hlau molten. Degasifiers tuaj yeem tshem tawm cov pa oxygen thiab lwm yam tsis xav tau roj xws li hydrogen ib yam nkaus.

Nws tsis yog deoxidizer ntawm hlau?

Carbon (coke), silicone, txhuas thiab lwm yam khoom siv rau slag deoxidation. Txij li thaum deoxidizers nyob rau hauv txoj kev difusion tsis tau qhia ncaj qha rau hauv cov hlau yaj, oxide non-metallic inclusions tsis tsim.

Si tua steel yog dab tsi?

Thaum steel tau deoxidized tag nrho ua ntej casting thiab tsis muaj roj tau hloov zuj zus thaum lub sij hawm solidification, cov hlau resultant hu ua hlau tua. Cov hlau no yog tus cwj pwm los ntawm qib siab ntawm tshuaj lom neeg homogeneity. … Cov hlau no hu ua "tua" vim nws ntsiag to solidifies nyob rau hauv pwm thiab tsis muaj roj evolves.

Yuav siv oxygen li cas hauv kev lag luam steel?

Cov txheej txheem oxygen yooj yim (BOP), txoj kev ua hlau uas cov pa ntshiab yog cua tshuab rau hauv da dej ntawm molten moj tej tawg-qhov cub hlau thiab seemCov pa pib ua cov txheej txheem ntawm exothermic. (kub tawm) cov tshuaj tiv thaiv, suav nrog oxidation ntawm cov impurities xws li carbon, silicon, phosphorus, thiab manganese.
