4.Product Description
1. Curvature
Qhov curvature ib 'meter' yuav tsum tsis pub tshaj 3 hli, thiab tag nrho curvature yuav tsum tsis txhob tshaj 0.3% ntawm tag nrho cov ntev.
2. Torsion
Lub channel steel yuav tsum tsis muaj qhov pom tseeb torsion.
5.Qhov hnyav thiab tso cai sib txawv
1. Kev xa khoom raws li qhov hnyav theoretical lossis qhov zoo tiag tiag.
2. Thaum xam qhov hnyav theoretical, qhov ceev ntawm cov hlau yog 7.85g / cm³.
6. Kev tshuaj xyuas txoj kev
1. Dimension soj ntsuam txoj kev
(1) Qhov ntsuas qhov siab yog nyob ntawm lub duav siab.
(2) Cov ceg dav yuav tsum tau kuaj xyuas yam tsis muaj kev cuam tshuam ntawm lub duav tsis sib xws.
(3) Tshawb xyuas lub duav deflection nrog tus pas ntsuas thiab ntsuas qhov ntsuas.
(4) Txheeb xyuas qhov ntev nrog tus pas ntsuas los yog daim kab xev ntsuas.
(5) Qhov nruab nrab ceg tuab yog kuaj ntawm lub yob thaum tig lub yob.
2. Qhov chaw soj ntsuam
Kev khoov deflection thiab sab ntug txoj kab nqes ntawm cov channel steel yuav tsum tau kuaj xyuas ntawm qhov deb ntawm tsis pub tsawg tshaj 750mm los ntawm qhov kawg.
