Galvanized steel hlua yog cov khoom sib tw los ntawm cov hlau hlau. Hauv nws cov khoom siv, nyias rods (xov) ntawm ntau yam thicknesses thiab zoo yog siv. Tag nrho cov ntawm lawv twist nyob rau hauv ib tug kauv nyob rau hauv ib tug strand. Txhua txoj hlua muaj ob peb txoj hlua sib tw ntawm tib hom thiab cov hlau los yog organic core. Cov tub ntxhais yog nyob rau hauv nruab nrab ntawm lub cable, nyob rau hauv nws cov voids thiab tiv thaiv cov nyob ib sab ntawm cov hlau los ntawm ntog. Impregnated nrog anti-corrosion roj, nws tiv thaiv lub puab txheej ntawm corrosion thaum lub cable yog khoov. Cov hlau uas siv tau tuaj yeem ua galvanized lossis uncoated, muaj ib puag ncig lossis zoo li tus seem. Nws lub zog tensile yog nyob rau hauv thaj tsam ntawm 900 txog 3500 N / mm2. Tus naj npawb ntawm cov hlua hauv txoj hlua, uas nyob ib ncig ntawm lub hauv paus, txiav txim siab nws cov qauv.
Cov hlua hlau sib txawv ntawm ib leeg hauv cov duab ntu, lub cevmechanical yam ntxwv ntawm cov xov hlau thiab muaj ntau tus qauv tsim. Qhov yooj thiab rigidity ntawm txoj hlua yog nyob ntawm hom khoom, hom tub ntxhais, nteg kev taw qhia, tus xov tooj ntawm cov xov hlau hauv ib txoj hlua. Cov hlua siv ntau dua, txoj hlua hloov tau yooj yim dua.
Nyob ntawm kev ua haujlwm, cov hlua hlau tau muab faib ua traction, reinforcing, lifting, cargo, towing, mine, bearing, etc. Cov hlua hlau yog cov khoom thauj khoom thauj, kev tsim kho, nqa cov qauv thiab tshuab. Qhov zoo ntawm cov ntawv txuas no ua kom muaj kev nyab xeeb ntawm kev siv txhua lub tshuab nqa.
Los ntawm kev tsim, hlau hlua (GOST 3241-80 lossis DIN 3051) yog qhov txawv ntawm cov hauv qab no:
- Single lay. Xws li ib tug cable muaj ib tug strand. Nws muaj cov xov hlau ntawm tib txoj kab uas hla retinue nyob rau hauv ib txheej (los yog ob peb txheej) nyob ib ncig ntawm ib tug hlau.
- ob lay. Txoj hlua no muaj ntau txoj hlua, uas yog ib lossis ob txheej, thiab nyob ib ncig ntawm lub hauv paus.
- Tsib zaug. Nws muaj peb txoj hlua uas sib tw ua ke thiab tsis muaj lub hauv paus.
Kev sib tw ntawm cov hlua tuaj yeem hla, ib sab lossis ua ke, sab laug lossis txoj cai, untwisted lossis non-untwisted twisting. Sab hauv, cov hlua ntawm cov hlau muaj qhov taw tes, kab, lossis dot-line kov.
Cov hlua hlau yog cov yam ntxwv ntawm cov hauv qab noformula: NM + L, qhov twg N yog tus naj npawb ntawm cov hlua, M yog tus naj npawb ntawm cov xov hlau hauv ib txoj hlua, L yog tus naj npawb ntawm cov hlua hauv txoj hlua. Piv txwv li, qhov nkag 636 + 1 txhais tau hais tias txoj hlua muaj rau 6 txoj hlua, txhua qhov muaj 36 xov hlau, thiab ib qho tseem ceeb.
Hlau cables yuav tsum tau muab kaw nruj nreem kaw rau ntawm spools (bobbins) los yog dov rau hauv me me coils. Los ntawm kev cuam tshuam ntawm ib puag ncig kev nruj, lub bay nrog ib lub cable yuav tsum tau tiv thaiv los ntawm ib daim ntaub npog nyob rau ntawm lub pallet ntoo (nyob rau hauv tshav ntuj huab cua, lub casing raug tshem tawm). Kev khoov ntau dhau ua rau muaj kev phom sij rau cov kab mob. Yog li ntawd, lub thawv rau nws yog xaiv kom zoo zoo. Nrog txoj hlua cia kom raug, kev pab cuam lub neej ntawm cov khoom yog unlimited.
