Kev tsim cov txheej txheem ntawm steel-cored aluminium stranded hlau feem ntau suav nrog cov kauj ruam tseem ceeb xws li kev npaj cov khoom siv raw, steel core kho, txhuas hlau stranding, thiab tom qab ua tiav. Precise coordination xyuas kom meej tias tus neeg xyuas pib muaj ob qho tib si siab zog thiab zoo heev conductivity.
Raw Material Preparation and Inspection
Steel Core Khoom: Feem ntau, siab - carbon steel hlau rod yog kos rau hauv steel hlau thiab ces galvanized los yog txhuas- clad los txhim kho corrosion kuj thiab mechanical zog. Qee cov khoom siv siab- kawg siv aluminium- clad steel hlau (xws li qib LB20 thiab LB35), nrog lub zog tseem ceeb tshaj 1800 MPa.
Aluminium Hlau Khoom: Siab-purity (Ntau dua los yog sib npaug rau 99.7%) electrolytic aluminium yog xaiv thiab tsim rau hauv tawv txhuas hlau los ntawm kev nruam casting thiab dov txheej txheem. Cov conductivity feem ntau tsis tsawg dua 61% IACS.
Hlau Core Pretreatment
Hlau Hlau Drawing: Cov hlau xaim hlau tau txo qis rau lub hom phiaj loj los ntawm ntau- dhau txheej txheem kos duab txias, tswj qhov ntev ntev ntawm ± 0.02 hli.
Kev kho deg:
Zinc Plating: Kub-dip galvanizing yog siv los ua ib txheej zinc txheej (kwv yees li 20-30 μm tuab) ntawm cov hlau hlau nto, tiv thaiv electrochemical corrosion.
Aluminium-Clad Steel: Ib txheej txheej aluminium yog densely coated rau steel hlau siv "Conform" nruam extrusion txoj kev, ua tiav metallurgical bonding thiab ho txhim kho corrosion kuj.
Tus neeg xyuas pib Stranding (Core Process)
Khoom siv: Ua tiav ntawm lub tshuab stranding los yog rab rawg stranding tshuab, txhawb ntau - txheej concentric stranding.
Cov txheej txheem tseem ceeb: Siv cov tub ntxhais kho steel raws li cov tub ntxhais hlau, strand aluminium ib leeg xov hlau txheej los ntawm txheej;
Cov khaubncaws sab nraud povtseg yog muab tso rau hauv qhov sib txawv (cov txheej txheem sab nraud yog txoj cai- tes / Z- kev taw qhia) txhawm rau tiv thaiv cov xoob xoob thiab txo qis AC impedance;
Tswj lub suab sib piv (txheej txheej tsis ntau dua li sab hauv txheej) kom muaj kev ruaj ntseg;
Untwisting stranding tuaj yeem siv los tiv thaiv ib leeg -hlau tus kheej-twisting thiab txhim kho cov txiaj ntsig.
