Cast Steel Txhaj Tshuaj

Cast steel txhajyog ib tug spherical hlau abrasive lug siv rau cov hlau nto kho. Nws yog tsim los ntawm melting seem hlau, atomizing cov hlau molten rau hauv spheres, ua raws li quenching thiab tempering. Nws yog feem ntau siv rau derusting, xuab zeb tshem tawm, descaling thiab tua peening, featuring siab nqi kev kawm thiab reusability.

Basic Properties

Kev sib xyaw: Feem ntaucarbon siab(0.85% -1.2% carbon), muaj manganese, silicon thiab lwm yam khoom uas tsis muaj impurities.

Qhov tshwm sim: Spherical los yog ze li tus kheej kheej zoo nrog du nto thiab siab sphericity.

Hardness: Qib tsis tu ncua: HRC 40–50; siab- qib carbon: HRC 57–62.

Particle Loj: Ua raws li cov qauv SAE, xws li S230 (0.2 hli) txog S780 (2.5 hli). Ntau qhov tshwj xeeb ntawm 3-10 mm kuj muaj.

Kev Pabcuam Lub Neej: Recyclable rau 2000 mus rau 3000 cycles, nrog cov plua plav tsawg thiab noj tsawg.

Txheej txheem ntau lawm

Melting: Melt tsim nyog seem hlau thiab alloys nyob rau hauv ib tug hluav taws xob arc rauv los yog nruab nrab zaus rauv ntawm qhov kub siab tshaj 1500 degree.

Atomization: Molten steel yog cuam tshuam los ntawm siab - dej siab los yog centrifugally atomized los ua cov tee kheej kheej uas khov rau hauv kev txhaj tshuaj.

Kev kho cua sov: quenching rau hardness txhim kho thiab tempering rau toughness li stabilize internal qauv thiab hardness.

Kev tshuaj ntsuam thiab muab qhab nia: Muab faib cov khoom los ntawm qhov loj me thiab qhov sib npaug, thiab tshem tawm cov hollow lossis deformed hais.

Cov ntawv thov tseem ceeb

Nto ntxuav: Kev tshem tawm xuab zeb rau castings, xeb tshem tawm thiab descaling ntawm forgings, steel phaj thiab steel qauv.

Txheej Pretreatment: Ua kom lub ntsej muag roughness thiab txheej adhesion rau nkoj, txuas hniav thiab ntim khoom.

Tua Peening: Kho cov iav, springs, crankshafts, bearings thiab lwm yam khoom kom ntev lub neej qaug zog thiab txhim kho kev ntxhov siab corrosion.

Lwm yam kev siv: Pipeline descaling, pob zeb txiav thiab pwm tu.

Kev sib piv nrogHlau Txiav Hlau Txhaj

Cast Steel Txhaj Tshuaj: Cov duab kheej kheej, zoo fluidity thiab kev tiv thaiv ib puag ncig nrog hardness. Zoo tagnrho rau kev tu thiab tua peening.

Hlau Txiav Hlau Txhaj: Cylindrical zoo nrog me ntsis npoo, muaj zog txiav lub zog thiab 30% -50% kev pab cuam lub neej ntev. Haum rau tshem tawm cov xeb hnyav thiab hnyav ua haujlwm.

Cov txheej txheem xaiv

Particle Loj: Kev txhaj tshuaj ntxhib (1.0–2.5 mm) kom tshem tawm cov kab mob hnyav; Kev txhaj tshuaj zoo (0.2-0.6 hli) rau kev kho kom zoo.

Hardness: HRC 40-50 rau cov khoom siv hlau zoo tib yam; HRC 57–62 rau siab- hardness qhov chaw xws li iav thiab bearings.

Cov xwm txheej ua haujlwm: Cam khwb cia hlau txhaj tshuaj yog qhov kev xaiv zoo tshaj plaws rau kev txhaj tshuaj blasting tshuab. Ib qho me me ntawm cov hlau txiav hlau txhaj tshuaj tuaj yeem sib xyaw rau kev tshem tawm xeb hnyav.
