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