Cov khoom ntawm Cored Hlau

Cored hlau, lub hnub qub vuam khoom nyob rau hauv metallurgical thiab mechanical manufacturing teb, tshuav nws superior kev kawm rau nws ua tib zoo tsim cov khoom muaj pes tsawg leeg. Nws feem ntau muaj ob ntu: sab nrauv steel sheath thiab lub hauv paus flux core. Sab nrauv steel sheath feem ntau yog ua los ntawm siab -zoo qis-carbon steel sawb. Qhov kev xaiv no tsis tsuas yog muab cov cored hlau zoo plasticity thiab toughness, tso cai rau nws los tiv thaiv ib puag ncig ib puag ncig kev cuam tshuam thaum vuam, tab sis kuj ua kom muaj txiaj ntsig zoo thiab ruaj khov thaum lub sij hawm vuam txheej txheem vim nws cov thermal conductivity zoo, yog li lav zoo weld.

Lub hauv paus flux core yog cov tub ntxhais ntawm cov hlau cored, thiab nws cov khoom siv ncaj qha cuam tshuam rau cov nyhuv vuam thiab cov khoom siv hlau. Nyob ntawm daim ntawv thov yuav tsum tau, cov tub ntxhais flux tuaj yeem sau nrog ntau yam hmoov hlau xws li ferroalloys, npib tsib xee, thiab chromium. Cov hmoov hlau no yaj sai sai thaum lub sij hawm vuam, sib txuas nrog cov hlau hauv paus kom tsim tau ib daim ntawv cog lus muaj zog metallurgical, txhim kho lub zog thiab corrosion kuj ntawm cov vuam. Piv txwv li, nyob rau hauv vuam scenarios xav tau lub zog siab thiab corrosion kuj, siv cored hlau uas muaj npib tsib xee thiab chromium tuaj yeem txhim kho cov khoom siv ntawm cov vuam, ua kom lub sij hawm ntev - ruaj khov ntawm qhov sib koom ua ke.
