Dab tsi yog cov txheej txheem casting ntawm cam khwb cia hlau log?

Nrum Hlau Log Casting yuav tsum nruj tswj tau nruj tshaj li melting, pwm, thiab tom qab ua kom paub meej lub zog thiab precision.

Cov txheej txheem tseem ceeb yog raws li hauv qab no:

MELTING: DUB hlau, seem cov hlau, coke, thiab alloys (xws li ferrosilicon thiab ferromanganese) tau sib xyaw ua kev ua tau zoo (hlau grey / cooj hlau). Das hlau yuav tsum muaj cov hlau ntxiv ntawm cov magnesium / Cerium alloy rau kev sib tw. Melting tau ua nyob rau hauv lub cupola lossis nruab nrab ntawm cov cub tawg (1400-1500 degree), tsis txaus ntseeg (leej faj thiab phosphorus) raug tshem tawm, thiab cov kab hlau molten thiab ntsuas kub yog sim.

Pwm: xuab zeb pwm feem ntau siv (tus nqi qis). Resin-txhawb cov xuab zeb, sodium silicate silicate xuab zeb, lossis hlau pwm tuaj yeem siv rau cov khoom siv nyuaj lossis cov khoom siab. Cov pwm muaj cov kab noj hniav (lub log tsheb), lub rooj vag (rau kev ua kom tsis txhob muaj hlau), kev tiv thaiv shrinkage kab noj hniav), thiab vents (rau kev tiv thaiv kev tiv thaiv cua cua). Cov chaw tseem ceeb (hais lus thiab cov chaw muab dej) xav tau cov duab tuab thiab tsim cua txias.

Moulding thiab Core Ua: xuab zeb thiab ib phau (av nplaum / resin) tau sib xyaw thiab sau rau hauv cov pwm, sib txuas los ua cov xuab zeb loj thiab qis dua. Cov kab ke hauv cov kab ke hauv (cov kab mob sab nraud Cov xuab zeb pwm thiab cov tub ntxhais kawm tau sib sau ua ke thiab ruaj khov nrawm kom tiv thaiv kev ua tsis ncaj.

Pouring: Cov hlau molten tau tso cai rau khom thiab deslagging raug tshem tawm. Ciav hlau yuav tsum tau spheroidization (ntxiv rau tus neeg sawv cev sib txawv) thiab inoculation (ntxiv ntawm ferrosilicon). Qhov ntsuas kub (1300-1400 degree) thiab kev nrawm yog tswj tau, thiab lub casting yog poured khovly rau hauv lub rooj loog raws lub rooj vag. Nqis rooj vag lossis hauv qab hauv qab tuaj yeem siv rau qhov chaw loj.

Kev tu xuab zeb: Tus casting yog txias rau hauv qab no 200℃ua ntej unpacking thiab vibrating lossis hydraulic tu cov xuab zeb. Kev tawm, Flash, thiab Burrs raug tshem tawm, thiab cov xuab zeb thiab cov xuab zeb tau muab tshem tawm los ntawm kev txhaj tshuaj blasting lossis sandblasting.

Kev Kho Cua Sov: Kev nyuaj siab pab txhawb kev ua haujlwm (550-650℃nrog qeeb txias). Cov tawv nqaij tawv (xws li ntug kev ua kom sov thiab kub, lossis nitriving) yuav ua rau cov kev coj ua zoo.

Inspection and Processing: Visual inspection, nondestructive testing (such as ultrasonic testing), mechanical properties (hardness, strength), and dimensional measurement are performed. Cov chaw tseem ceeb (HUB Bore thiab ntug) yog precision-machined kom meej meej installations.

Cov Txheej Txheem Nta: Xuab Zeb Casting yog cov qauv kev txhim kho, muab tau zoo thiab tus nqi qis. Kev ua tau zoo thiab tus nqi sib npaug ntawm cov npliag

Kev tswj ntawm kev sib xyaw, pwm, thiab cua txias. Zas cov hlau log yub thiab kev kho cua sov, ua rau muaj kev sib npaug, ua rau lawv tsis kam, ua rau lawv haum rau cov ntawv siv hnyav.
