Bulat yog cov hlau uas, ua tsaug rau nws cov txheej txheem tsim tshwj xeeb, txais cov txheej txheem tshwj xeeb saum npoo uas muab kev ywj pheej thiab tawv. Txij li lub sijhawm txheej puag thaum ub, cov khoom siv no tau siv rau kev tsim cov khoom lag luam zoo, txij li cov ntaub ntawv niaj hnub tsis muaj kev sib xyaw ua ke ntawm cov tawv tawv, elasticity, muaj peev xwm ua kom lub xeev ntse, malleability.
Cov Lus Qhia

Nyob rau hauv cov nqe lus ntawm cov pa tsis sib xws, damask steel txawv ntawm cov hlau zoo tib yam nyob rau hauv cov pa roj carbon siab nyob rau hauv nws cov muaj pes tsawg leeg, txawm li cas los xij, hais txog nws lub cev cov yam ntxwv, damask steel khaws cov malleability cov yam ntxwv ntawm cov pa roj carbon tsawg, thiab tom qab ua kom tawv hlau nws ua txawm tias tawv tawv dua li cov pa roj carbon tsawg, uas cuam tshuam nrog cov qauv sab hauv ntawm damask steel. Nyob rau hauv cov tsos, damask steel tuaj yeem ib txwm muaj qhov txawv txav vim muaj qhov txawv ntawm qhov qauv chaotic rau saum npoo, uas tau tsim thaum lub sijhawm crystallization.

Muaj ntau txoj hauv kev los tsim cov damask, ob qho tib si niaj hnub thiab qub. Niaj hnub no tus damask tseem tab tom yaj. Ntsaws cov khoom seem ntawm damask steel rau hauv cov hlau ua kom sov: cov hlau tsis muaj cov ntsiab lus tsis zoo lossis cov hlau, uas yaj thaum kub txog 1650 degrees. Tom qab ntawd, ntxiv silicon thiab txhuas rau cov hlau tsis muaj hlau, thiab tsuas yog tom qab ntawd - graphite. Ua li no, hluavtaws npua hlau yog tsim nyob rau hauv lub tshuab ua kom sov, qhov uas cov pa roj carbon monoxide yuav muaj li 3 feem pua.

Tom ntej no, ntxiv cov txhuam zoo ntawm cov hlau tsis zoo lossis roj carbon hlau tsis zoo rau cov hlau cam khwb cia hlau. Cov khoob no lossis tej daim me me yuav tsum qhuav thiab huv uas tsis muaj paib tsis muaj pa ntawm lub ntsej muag. Nws yog ib qho tsim nyog los qhia cov kev sib tsoo maj mam, nws tag nrho qhov loj yuav tsum yog los ntawm 50 txog 70 feem pua ntawm qhov loj ntawm qhov cam ntawm cov hlau cam hauv qhov cub tawg.

Thaum cov khoob khoob yog yaj, cov hlau yuav zoo li slurry, yog li ntawd, nrog txhua qhov kev qhia tshiab ntawm cov hlau, lub tshuab ua kom sov yuav tsum rov kho dua. Tom qab ntxiv tag nrho cov ntim ntawm cov chips, hlau tau rov kho dua, tab sis tsuas yog mus rau ib lub xeev uas nws khaws cia tus qauv inhomogeneous.
Kauj ruam 5
Tom qab ntawd, muab cov hlau damask tso rau hauv cov kab ua kua pwm lossis tawm hauv qhov cub los ua kom tawv. Hauv thawj qhov xwm txheej, damask steel nrog ferrite interlayers thiab qis cov ntsiab lus carbon (txog 0.05%) yog tsim, thiab hauv ob, damask steel nrog carbon interlayers thiab cov pa roj carbon ntau (nce txog 1%).
