Cored Hlau
Cored xov hlau, tseem hu ua FCored xov hlau los yog Flux-Cored xov hlau, yog dav siv nyob rau hauv metallurgical kev lag luam rau ntau yam kev siv. Lawv muaj ib tug metallic sheath nyob ib ncig ntawm ib tug tseem ceeb ntawm cov ntaub ntawv flux. Cov xov hlau no muaj ntau qhov zoo dua li cov xov hlau ib txwm muaj, ua rau lawv nrov hauv kev vuam, steelmaking, thiab lwm yam txheej txheem hlau.
Khoom Taw Qhia
Alloyed flux cored hlau yog ib hom khoom siv hlau siv hauv cov hlau thiab cov chaw tsim khoom vim nws cov khoom tshwj xeeb. Cov xov hlau no yog tsim los ntawm cov hmoov tshwj xeeb ntawm cov hlau alloying thiab lub cev sib xyaw ua ke los ua ib qho khoom siv hlau qhwv nrog ib daim hlau nyias. Tom qab ntawd cov hlau yog siv hauv steelmaking thiab casting.
Cored kabfeem ntau yog siv hauv steelmaking. Nws yog qhov zoo vim tias nws tuaj yeem hloov kho thiab tswj kom muaj cov qib tsim nyog ntawm cov ntsiab lus oxidizable thiab cov kab mob, uas ua rau kom muaj cov txiaj ntsig zoo, txo cov nqi melting, shortens melting lub sij hawm, thiab raug tswj muaj pes tsawg leeg.
Ib qho tseem ceeb ntawm cov hlau cored yog silicon-calcium CaSi hlau, uas yog siv dav hauv kev lag luam steel. Hom hlau no yog ua los ntawm silicon, calcium thiab lwm yam alloying ntsiab. Cov silicon thiab calcium yog ua ke nyob rau hauv txoj cai proportions thiab sib tov los tsim cov hlau. Tom qab ntawd cov hlau yog qhwv nrog ib daim ntawv nyias ntawm cov hlau los ua ib qho tseem ceeb ntawm cov hlau. Cov ntsiab lus silicon thiab calcium sib npaug sib npaug thoob plaws hauv cov tub ntxhais hlau, uas muaj ntau yam zoo rau steelmaking.
Cored hlau muaj ntau yam zoo dua lwm hom hlau. Ua ntej, nws yog ntau yam heev thiab tuaj yeem siv rau ntau yam kev siv. Nws kuj tseem yoog tau rau cov txheej txheem ntau lawm thiab tuaj yeem siv los tsim ntau hom hlau.
Lwm qhov zoo dua ntawm cored hlau yog tias nws tuaj yeem pab ua kom cov hlau molten ntshiab thiab ib nrab hloov cov hom thiab cov duab ntawm cov khoom, txhim kho qhov zoo ntawm cov hlau molten thiab txhim kho cov txheej txheem casting. Qhov no ua rau nws yog ib feem tseem ceeb ntawm cov txheej txheem steel.
Zuag qhia tag nrho, alloyed cored hlau yog ntau yam thiab hloov tau yooj yim alloy cov khoom siv hauv steelmaking thiab foundry industries. Nws cov khoom ua rau nws yog ib qho tseem ceeb hauv kev tsim cov hlau zoo. Muab nws cov txiaj ntsig zoo heev, nws tsis yog qhov xav tsis thoob tias cov hlau cored tau dhau los ua kev xaiv nrov ntawm ntau lub tuam txhab steel thiab foundries.
Paub meej ntawm cov khoom:
Daim ntawv thov
Cored hlau zoo: Cov tub ntxhais hlau txhaj tshuaj tshuab tau hloov txoj kev txhaj tshuaj ntawm ib rab phom refractory hmoov thiab ua pov thawj los ua ib txoj hauv kev tseem ceeb hauv cov txheej txheem metallurgical theem nrab.
Kev kub ceev nruam
Ua tau raws li qhov yuav tsum tau ua rau cov khoom siv tshuaj lom neeg hauv casting
Lub sijhawm ua haujlwm luv dua thiab raug dua
Zoo heev repeatability
Q: Dab tsi yog cored hlau siv rau?
A: Lub cored hlau yog dav siv nyob rau hauv steelmaking technology.
1, Nws yog qhov zoo rau kev kho thiab tswj cov ntsiab lus ntawm cov ntsiab lus oxidizable yooj yim thiab cov kab mob, thiab tuaj yeem ua rau kom cov khoom lag luam zoo, txo tus nqi smelting, txo lub sij hawm smelting, thiab tswj cov muaj pes tsawg leeg.
2, Nws tuaj yeem ua lub luag haujlwm hauv kev ua kom cov hlau molten ntshiab thiab ib nrab hloov qhov xwm txheej thiab cov duab ntawm cov khoom siv, txhim kho cov hlau molten zoo, thiab txhim kho lub xeev casting.
3, Siv cov hlau cored los ua cov hlau molten, cov ntsiab lus alloy hnov ntxhiab hauv cov hlau molten, uas tuaj yeem zam qhov oxidation theem nrab. Tom qab cov tshuaj tiv thaiv, qhov ntab tus nqi ntawm cov inclusions yog ceev, thiab cov nyhuv purification yog uniform.
4, Kev siv cov hlau cored hauv steelmaking lossis casting tuaj yeem zam tsis txhob nqa roj rau hauv cov hlau molten.
5, Cov khoom siv rau kev ntxiv cov alloys cored hlau yog qhov yooj yim thiab txhim khu kev qha, nrog cov hneev taw me me, tsim nyog siv rau hauv kev cob qhia nqaim
