1. Cov khoom xyaw
Q:Dab tsi yog cov khoom siv feem ntau siv rau cov kav dej hauv idler rollers?
A:Feem ntauqis- carbon steel (piv txwv li, Q235, ASTM A36)los yogcarbon steel qauv (piv txwv li, # 20 steel, ASTM A53)rau lub zog sib npaug, weldability, thiab hnav tsis kam.
2. Cov kauj ruam tseem ceeb ntawm kev tsim khoom
Q:Dab tsi yog cov txheej txheem tseem ceeb hauv kev tsim cov kav dej welded?
A:
Sawb txoj kev → Siab - vuam zaus (HFW) → Deburring → Sizing / Straightening → Tsis yog-kev kuaj kev puas tsuaj (NDT, piv txwv li, ultrasonic/eddy tam sim no).
3. Txheem Dimensions
Q:Dab tsi yog cov qauv specifications rau idler roller pipes?
A:
OD:60–219 hli |Phab ntsa thickness:2.0–8.0 hli |Ntev:Kev cai (piv txwv li, 500-1500 mm ib ntu).
Tolerance qauv:TS EN ISO 3183los yogASTM A53rau qhov tseeb qhov tseeb.
4. Kev Tswj Xyuas Kev Ntsuas Zoo
Q:Yuav ua li cas kom cov yeeb nkab ncaj thiab roundness?
A:
Laser - coj calibrationthaum dov.
Tshaj tawm - kev tshuaj xyuas ntau lawm:Tsawg dua los yog sib npaug li 0.5 mm / m straightness sib txawv, Tsawg dua lossis sib npaug li 1% ovality.
5. Kev kho deg
Q:Cov txheej txheem dab tsi yog siv los yog kev kho mob?
A:
Galvanization (Zinc txheej)rau kev tiv thaiv xeb.
Epoxy hmoov txheejrau corrosive ib puag ncig (xws li, mining).
Yeem:Sab hauv polishingkom txo kev sib txhuam.
