Forging

Preheat cov hlau kom zoo, kub rau 1150 oC - 1200 oC qhov siab tshaj plaws, tuav kom txog thaum ntsuas kub tsis sib xws thoob plaws hauv seem.
Tsis txhob forge hauv qab 850 oC.Ua raws li kev ua haujlwm forging lub workpiece yuav tsum tau txias kom qeeb li sai tau.

Kev kho cua sov

Thaum tshav kub kub steels mus rau 800 oC - 850 oC, tuav kom txog thaum qhov kub thiab txias tsis sib xws thoob plaws hauv seem thiab txias hauv qhov cub.

Hardness

Anneal: Tsawg dua los yog sib npaug rau 220HB Q ntxiv rau T: 28-34HRC HEAT TREAT MENT 55-62HRC

Daim ntawv thov

1. Tsim cov ntaub ntawv uas yooj yim rau txheej txheem thiab zoo hauv polishing

Nrog rau kev tsim kho qhov muag disc, disk, prism thiab lwm yam precision, qhov kev thov kom yooj yim machining daim iav steel nce.
Cov hlau no muaj tsawg dua cov hlau tsis huv, zoo metallographic qauv zoo, tsis muaj fiber ntau cov kev taw qhia. Nws yog tus
Txoj kev loj hlob tseem ceeb ntawm cov yas pwm steel.

2. Cov hlau tsis muaj corrosion

Nyob rau hauv cov txheej txheem ntawm kev ua haujlwm ntev thiab kev saib xyuas ntawm cov pwm, nws yooj yim rau xeb thiab corrosion, thiab nrog rau qhov sib ntxiv ntawm
ntau yam khoom nyob rau hauv yas molding, cov pwm yog yooj yim rau corrosion. Yog li ntawd, nws yuav tsum tau txhim kho corrosion
tsis kam ntawm lub hauv paus khoom lub cev, thiab ib co corrosion-resistant stainless hlau tau tsim.

3. Maraging alloy hlau

Cov hlau zoo li no muaj cov khoom siv kho tshuab txaus thiab cov txheej txheem zoo heev, tshwj xeeb tshaj yog lub zog siab, toughness, hnav
tsis kam, tsis tshua muaj coefficient ntawm thermal expansion, yog cov hlau zoo rau kev tsim cov tshuaj molding, tab sis tus nqi yog
kim.

4. Cemented carbide

Feem ntau yog siv nyob rau hauv zus tau tej cov siab lub neej yuav tsum, zus tau tej cov loj batch ntawm pwm
