Rau roughing yob, lub zog thiab thermal cracking kuj yog qhov tseem ceeb. Cov rolls ua hauj lwm ntawm ib tug me me 20- yob zeb hnyav tsuas yog hais txog 100 grams, thaum cov kev txhawb nqa yob ntawm lub phaj hnyav hnyav tshaj 200 tons. Thaum xaiv cov yob, thawj kauj ruam yog xaiv cov khoom tseem ceeb ntawm cov kabmob (ntau yam ntawm cov hlau cam khwb cia, cam khwb cia hlau, lossis forged steel, thiab lwm yam) raws li lub zeb cov kev xav tau ntawm lub zog.
Hardness
Rau kev ua tiav rolls, qhov ceev yog siab dua, thiab cov khoom dov zaum kawg yuav tsum muaj qee qhov zoo. Yog li ntawd, hardness thiab hnav tsis kam yog qhov tseem ceeb. Tom qab ntawd, qhov hnav tsis kam yuav tsum tau siv rau kev siv yob yog txiav txim siab. Vim tias kev hnav cov txheej txheem ntawm cov yob yog qhov nyuaj heev, suav nrog kev ntxhov siab, cov cua sov thaum lub sij hawm dov, txias, cov tshuaj lom neeg ntawm lubricating media, thiab lwm yam, tsis muaj kev sib koom ua ke rau kev ntsuam xyuas cov yob hnav tsis kam. Txij li thaum hardness yog ib qho yooj yim los ntsuas thiab muaj peev xwm cuam tshuam kev hnav tsis kam nyob rau hauv tej yam kev mob, ib tug radial hardness nkhaus feem ntau yog siv los kwv yees lub yob qhov hnav tsis kam Performance index.
Impact Resistance
Tsis tas li ntawd, muaj qee qhov kev xav tau tshwj xeeb rau cov yob. Piv txwv li, thaum qhov txo qis loj, cov yob yuav tsum muaj zog tom qab muaj peev xwm thiab muaj kev cuam tshuam siab.
Nto tiav
Thaum dov nyias- ntsuas cov khoom, cov kev xav tau rau yob rigidity, uniformity ntawm microstructure, machining raug, thiab nto tiav yog nruj dua.
Machining Performance
Thaum dov cov qauv hlau nrog txoj kev hla - ntu, kev ua haujlwm ntawm cov txheej txheem ua haujlwm ntawm lub yob lub cev yuav tsum tau txiav txim siab.
Thaum xaiv cov yob, qee qhov kev xav tau ntawm kev ua haujlwm feem ntau tsis sib haum. Roll purchase thiab tu cov nqi yog siab heev. Yog li ntawd, qhov zoo thiab kev lag luam zoo thiab qhov tsis zoo yuav tsum tau ua tib zoo ntsuas los txiav txim siab seb puas yuav siv cam khwb cia lossis forged yob, alloy lossis tsis yog - alloy rolls, thiab ib qho - khoom lossis cov khoom sib xyaw.
