1. Kev sib raug zoo ntawm cov khoom ntawm txhuas thiab hlau yog dab tsi?
Thaum txhuas ntxiv rau cov hlau ua cov deoxidizer lossis alloying, nws lub peev xwm deoxidizing muaj zog ntau dua li ntawm silicon thiab manganese. Lub luag haujlwm tseem ceeb ntawm txhuas hauv cov hlau yog txhawm rau txhim kho cov qoob loo loj thiab txhim kho cov nitrogen hauv cov hlau, yog li txhim kho qhov cuam tshuam ntawm cov hlau thiab txo qhov nyiam ntawm qhov txias luv thiab kev laus. Aluminium kuj tuaj yeem txhim kho corrosion kuj ntawm cov hlau, tshwj xeeb tshaj yog thaum siv nrog cov ntsiab lus xws li molybdenum, tooj liab, silicon, chromium, thiab lwm yam., cov nyhuv tseem zoo dua.
2. Dab tsi yog qhov cuam tshuam ntawm oxygen rau cov khoom ntawm cov hlau?
Solubility ntawm oxygen nyob rau hauv cov khoom hlau yog tsawg heev, feem ntau yog muaj nyob rau hauv daim ntawv ntawm oxide inclusions. Yog li feem ntau ntawm kev suav nrog hauv cov hlau, tshwj tsis yog qee cov sulfides, yog oxides. Cov hlau tsis muaj hlau yog qhov tseem ceeb ntawm kev puas tsuaj rau cov hlau, thiab muaj qhov cuam tshuam loj rau lub zog qaug zog, kev ua haujlwm, ductility, toughness, vuam kev ua tau zoo, HIC tsis kam, corrosion kuj, thiab lwm yam khoom ntawm hlau. Cov ntsiab lus ntawm cov pa oxygen siab tuaj yeem ua rau muaj qhov tsis xws li cov npuas subcutaneous nyob rau hauv qhov nruam casting billet, uas tuaj yeem ua rau lub ntsej muag zoo ntawm daim tawv nqaij.
3. Vim li cas peb thiaj xav tau tapping los ntawm slag skimming?
Tapping los ntawm slag txo lossis skimming yog ib qho tseem ceeb ntawm kev tsim cov hlau ntshiab. Nws lub hom phiaj yog los pab txhawb kev tswj xyuas cov tshuaj muaj pes tsawg leeg ntawm cov hlau molten, txo cov phosphorus rov qab zoo hauv cov hlau molten, txhim kho qhov nqus ntawm cov ntsiab lus alloy, thiab txo cov kev siv hlau. Pab kom txo tau cov ntsiab lus ntawm inclusions hauv steel thiab txhim kho cov nyhuv refining ntawm steel ladles. Nws kuj tseem muaj txiaj ntsig los txo cov corrosion ntawm cov ntaub ntawv refractory hauv steel ladles. Nyob rau tib lub sijhawm, nws kuj txhim kho lub neej kev pabcuam ntawm lub converter taphole.
