Cov txheej txheem tseem ceeb ntawm quenching thiab tempering kho ntawm Weathering Steel Sculptures

Los ntawm cov cua sov thiab cua txias ntawm qhov saum npoo ntawm weathering steel sculpture castings, txoj kev kho cua sov hlau hloov cov khoom nto. Kev txhim kho cov khoom ua haujlwm yog qhov tseem ceeb rau quenching thiab tempering. Kev laus kev kho mob yog ib qho ntawm cov kauj ruam tseem ceeb tshaj plaws hauv qhov chaw quenching thiab tempering. Tsuas yog los ntawm kev nkag siab zoo dua kev kho mob ntawm qhov chaw quenching thiab tempering peb tuaj yeem siv nws zoo dua. Cov kws tshaj lij kev tshaj lij los ntawm cov chaw tsim khoom huab cua huab cua hauv qab no yuav pab txhua tus nkag siab nws ua ke.
Cov cua kub kub rau saum npoo quenching thiab tempering kho yog feem ntau ntawm 780-820 degree . Rau huab cua steel duab puab cov ntaub ntawv raws li ductile qhov chaw, 760-780 degree raug xaiv. Qhov tseem ceeb yog tiv thaiv cov siv lead ua kom tuab thiab cuam tshuam rau lub zog. Kev tswj qhov kub thiab txias precision ntawm kev laus kho yuav tsum nruj me ntsis tswj nyob rau hauv ± 5 degree. Lub sij hawm rwb thaiv tsev feem ntau tuaj yeem xam raws li 1 teev / 25mm. Thaum beryllium bronze yog cua sov kho thiab tempered nyob rau hauv huab cua los yog txo qhov cua, ib tug oxide zaj duab xis yuav tsim nyob rau saum npoo. Txawm hais tias qhov cuam tshuam ntawm lub cev tom qab kev laus tsis zoo, nws yuav cuam tshuam rau lub neej kev pabcuam ntawm cov cuab yeej kos duab txias.

Weathering steel me toj roob hauv pes phab ntsa
Txhawm rau tiv thaiv oxidation, nws yuav tsum tau rhaub hauv lub tshuab nqus tsev sintering los yog hauv cov tshuaj ammonia, tsis tshua muaj roj, thiab oxidizing cua kom tau txais qhov ci ntsa iab quenching thiab tempering nyhuv. Tsis tas li ntawd, kev saib xyuas yuav tsum tau them rau txo qis lub sijhawm tsiv teb tsaws ntau npaum li qhov ua tau, txwv tsis pub nws yuav cuam tshuam cov txiaj ntsig ntawm kev kho lub sijhawm-rhiab heev. Cov ntaub ntawv nyias tsis tuaj yeem tshaj 3 vib nas this, thiab cov huab cua dav hlau cov duab puab tsis tuaj yeem tshaj 5 vib nas this. Dej feem ntau yog siv los ua cov khoom siv kho cua sov, thiab cov roj kuj tseem tuaj yeem siv rau huab cua steel duab puab qhov chaw nrog cov duab zoo nkauj los tiv thaiv deformation.
