Cov lifts yog dab tsi?
Txheem
hniav thiab ncej
Cov hniav thiab ncej ntawm ib tug raug hoist yog tsim los ntawm ib daim ntawm forged vanadium los yog carbon hlau.Dab tsi yog vanadium thiab vanadium steel?
Vanadium yog ib qho nyuaj, silver-grey, ductile thiab malleable hlau yam.
Vanadium hlau yog ib hom hlau alloyed nrog vanadium rau ntxiv zog, hardness, thiab kub tsis kam. Vim yog kev siv zog loj heev uas nkag mus rau hauv lub tshuab nqa, nws yuav tsum tau ua los ntawm cov hlau muaj zog.
carbon steel yog dab tsi?
Cov pa roj carbon steel yog hom hlau alloy uas muaj cov ntsiab lus carbon tsawg kawg ntawm 0.3%. Cov khoom ntawm carbon steel nyob ntawm seb muaj pes tsawg carbon nws muaj. Muaj peb yam tseem ceeb ntawm carbon steel: qis, nruab nrab thiab siab carbon. Lifts feem ntau yog ua los ntawm nruab nrab carbon steel.
1. qis carbon steel
Muaj txog li 0.3% carbon. Qhov no nce ductility, tab sis tsis cuam tshuam rau lub zog. Ductility yog ib qho kev ntsuas ntawm qhov kev ntxhov siab npaum li cas cov khoom tuaj yeem tiv taus ua ntej nws tawg.
2. Nruab nrab carbon steel
Cov pa roj carbon monoxide 0.3-0.5%. Nws yog qhov zoo tagnrho rau machining lossis forging thiab qhov chaw hardness yog xav tau.
3. High carbon hlau
Muaj ntau tshaj 0.5% carbon. Qhov no yuav nyuaj heev thiab withstands siab shear loads thiab hnav.
"Forging" yog dab tsi?
Forging yog txheej txheem tsim khoom uas cov hlau deformed (feem ntau thaum kub) rau hauv cov duab uas xav tau siv lub zog compressive, xws li tshuab los ntawm rauj.
Qhov twg zoo dua?
Cov hlau no tsis txawv ntau ntawm ib leeg vim ob leeg siv vim lawv qhov hardness, lub zog thiab durability. Txawm hais tias vanadium hlau feem ntau alloyed nrog chromium, qhov no ua rau cov cuab yeej tiv taus corrosion, abrasion, thiab oxidation.Kev ua haujlwm
Nqa tes yog tsim los ntawm ntau yam khoom siv, tab sis feem ntau yog cov yas tawv, ntoo, thiab muag muag sib txawv.ntoo tuav
Tsob ntoo ntoo tseem nrov heev thiab muab cov neeg siv nrog kev tuav zoo, ergonomic thiab zoo nkauj.Hard yas tuav
Rigid yas tuav yog nrov heev vim lawv hnav, ergonomic thiab ruaj khov heev.Yas kov nrog mos tuav
Soft-grip yas grips muab tus neeg siv nrog kev ruaj ntseg thiab xis tuav, ua kom yooj yim siv thiab tsis tshua muaj kev plam ntawm tes. Nco ntsoov tias tus qauv no tseem muaj qhov kawg ntawm tus kov kom koj tuaj yeem dai nws hauv lub cuab yeej tso.
