Taw qhia rau flux cored hlau
Flux cored hlau kuj hu ua hmoov cored hlau thiab tubular xaim. Nws muab faib ua ob pawg: kev tiv thaiv zoo thiab kev tiv thaiv uas tsis yog-aerated. Qhov nplaim ntawm cov nplaim hluav taws xob yog tib yam li cov khoom hlau, uas ua los ntawm cov uas tsis muaj carbon los sis cov hlau tsawg-tsawg los ntawm cov yas zoo. Txoj kev tsim muaj cov kauj ruam ntawm: dov lub hlau khawm rau hauv U-shaped cross-section zoo, ntxiv cov koob hmoov sib xyaw hmoov sib tov mus rau ntawm U-puab pob sawb, dov nws nrog lub pob zeb, thiab thaum kawg yog nqus cov tshuaj txawv cov lus qhia los ntawm daim duab. Tub ntxhais hlau.
Ua ntej thaum xyoo 1950, cov ntaub thaiv hluav taws roj hmab tau pib tsim, tab sis nws tsuas yog siv dav siv coj los siv rau xyoo 1957. Qhov no txhais tau hais tias yog ib qho kev sib txuas ntawm cov kev zoo ntawm cov hlab arc vuam thiab CO2 vuam (raug xa mus rau khoom). Cov kua nplaum yog qhwv hauv cov xaim thiab tiv thaiv los ntawm cov pa roj carbon CO2 sab nraud los ua ib qho kev sib txawv thiab ruaj khov thiab qis qis thaum lub vuam siv. Nws yog tsiag ntawv los ntawm nws. Thaum pib ntawm txoj kev loj hlob, tsuas yog qhov dav hlau diam iav vuam hlau (2.0-4.0mm) tau siv rau kev lag luam ncaj nraim thiab txoj hlua ntawm txoj haujlwm loj. Nws tsis yog kom txog rau thaum xyoo 1972 tias txoj kev loj hlob ntawm txoj hlua me me vuam hlau tau nthuav dav rau thaj tsam ntawm lub ntsej muag cored hlau.
Cov xov tiv thaiv ntawm tus kheej tau tsim tawm sai sai tom qab cov ntaub thaiv hluav taws xob tau siv rau lub lag luam thiab tau txais kev pom zoo sai sai los ntawm kev lag luam rau kev siv.
Qhov loj tshaj ntawm qhov ob yog twb tau teev nyob rau hauv chav tsev thib ob. Chav tsev no tsuas yog rau tag nrho cov kev sib tham.
Raws li cov ntaub ntawv: Nyiv lub welding rods accounted rau 4% ntawm tag nrho cov khoom siv vuam siv los ntawm 5% ntawm xyoo 1985; qhov kev faib ua feem ntawm cov xaim hluav taws xob tau muaj ze li ntawm 30%. Nyob rau hauv Tebchaws Asmesliskas, qhov feem pua ntawm cov hlua vuam tau poob qis tshaj 40%, thiab cov xov hluav taws kub muaj ze li 40%; cov kev sib cog lus hauv Western Europe cov nyiaj rau 30%, thiab cov xov hluav taws xob cuav nyiaj rau txog 20%. Nws tuaj yeem pom tias cov xov hluav taws kub muaj qhov pom tau zoo tshaj rau cov khoom siv hluav taws xob thiab cov argon arc welding hlau, mas yog hloov cov txheej txheem sib txuas ntawm kev sib txuas ua ke, ua kom tsis txhob muaj cov pob qij txha thiab txhim kho qhov zoo ntawm lub pob txha. Kuj muaj kev ua kom zoo dua qub thiab txuag hluav taws xob.
Flux cored hlau yog faib ua seamed thiab seamless flux cored hlau raws li cov yam ntxwv ntawm cov khoom. Cov xov tooj ntawm cov xaim xim tsis muaj ntsev tsis muaj hlau yog hlau, ploj thiab cov dej noo thaum lub sij hawm xaim hluav taws xob txheej txheem thiab cov conductivity thaum lub vuam txheej txheem yog qhov zoo tshaj rau cov pleev xim cored hlau.
