Cov teeb meem dab tsi tuaj yeem ua rau lub zog tsis sib luag ua rau lub caij txias - dov puag ncig bar ntau lawm?
Cov khoom tsis sib xws thickness thiab hardness ua rau muaj kev pheej hmoo ntawm deg tsis xws luag los yog tawg.
Dab tsi yog qhov txwv rau txias -rolled round bar deformation?
Tag nrho cov deformation yuav tsum yog 20% mus rau 60%, nrog rau ib qho kev hla tsawg dua los yog sib npaug li 15% kom tsis txhob muaj zog thiab tawg.
Vim li cas thiaj yuav tsum tau kho cua sov tom qab txias dov?
Stainless hlau feem ntau yog kho, thaum carbon steel thiab alloy steel feem ntau annealed los kho cov khoom siv kho tshuab lossis tshem tawm cov kev ntxhov siab sab hauv.
Dab tsi yog cov cuab yeej siv los tsim cov khoom txias -rolled round bar?
Ib leeg- sawv dov mills (rau cov khoom me me) thiab cov rolling mills txuas ntxiv, ntxiv los ntawm cov qhov cub tawg, kos duab tuag, thiab cov cuab yeej tshuaj xyuas saum npoo.
Kev ua tau zoo thiab zoo
Dab tsi yog cov yam ntxwv ntawm cov tshuab txias txias -rolled round bar?
Tensile zog, yield zog, elongation, hardness (xws li Brinell HB), thiab txo qhov chaw.
