Welong Supply Chain, muaj peev xwm tsim BOHLER S390 log nrog hardness 65 ~ 69HRC rau cov cuab yeej drilling. BOHLER 5390 MICROCLEAN yog tsim los ntawm cov hmoov-metallurgy txoj kev Segregation-dawb thiab homogeneous hlau hmoov ntawm siab tshaj plaws purity thiab txaus granulation yog ua tiav rau homogeneous thiab segregation-free high speed steels ntawm zoo isotropic zog nyob rau hauv ib tug diffusion txheej txheem coj qhov chaw ntawm high pressures thiab kub.
BOHLER S390 lub log tuaj yeem ua kom tawv. 1150 10 1230 ° ((2102 txog 2246 ° F)
Roj, ntsev da dej (500- 550 ° C (932 -1022 ° F), huab cua, roj. Qhov kub thiab txias rau qhov chaw ntawm cov duab yooj yim, qis dua rau qhov chaw ntawm cov duab. Soaking lub sij hawm tom qab cua sov tag nrho cov seem ntawm ib tug workpiece 80 vib nas this yam tsawg kawg nkaus yog yuav tsum tau rau dissolving txaus carbides lub sij hawm ntau tshaj 150 vib nas this kom tsis txhob detriments los ntawm oversowing.
Nyob rau hauv kev xyaum es tsis txhob soaking sij hawm lub sij hawm ntawm raug los ntawm qhov chaw ntawm lub workpiece nyob rau hauv lub Saith da dej tom qab preheating kom txog thaum tshem tawm (suav nrog rau cov theem ntawm cua sov mus rau lub teev saum npoo kub thiab cua sov mus rau lub kub nyob rau hauv tag nrho cov seem) yog siv. Vacuum hardening yog ua tau. Lub sij hawm nyob rau hauv lub tshuab nqus tsev vacuum nyob ntawm seb lub workpiece loj thiab qhov cub tsis
Tom qab ntawd, BOHLER S390 lub log tuaj yeem tempering. Ua cua sov qeeb rau qhov kub thiab txias tam sim ntawd tom qab hardening / sij hawm hauv qhov cub: 1 teev rau txhua 20mm ntawm workpiece thickness, tab sis tsis pub tsawg tshaj 2 teev / cua txias (tsawg kawg tuav lub sij hawm: 1 teev). 1st tempering thiab 2nd tempering rau qhov xav tau ua haujlwm hardness. 3rd tempering rau kev ntxhov siab, 30 ~ 50 ° C (86 ~ 122 ° F) hauv qab qhov kub siab tshaj plaws. Tau hardness tom qab tempering 65 - 69 HRC.
Hais txog cov txheej txheem tsim khoom ntawm BOHLER S390 lub log: machining (chamfering) + hniav profile machining + kev kho cua sov. Ua tib zoo saib xyuas kom tso qhov tsawg kawg nkaus ntawm 0.50mm rau ntawm ib sab ntawm sab nraud txoj kab uas hla thaum tig rau hlau txiav rau tshuab cov hniav profile.
