Cov kav hlau kav hlau -Centrifugal cam khwb cia
Cov txheej txheem tseem ceeb ntawm cov kav hlau kav yog centrifugal casting (uas kuj yog cov txheej txheem tseem ceeb hauv kev lag luam). Cov txheej txheem no feem ntau yog spheroidizing cov graphite hauv cov cam khwb cia hlau los ua cov duab kheej kheej, yog li txhim kho cov cuab yeej cuab tam ntawm cov yeeb nkab.
Cov Txheej Txheem Tseem Ceeb
Raw Material Smelting
Raw Material Smelting: Npua hlau, seem hlau, thiab cov khoom siv rov ua dua tau muab pub rau hauv nruab nrab - zaus induction rauv hauv ib qho piv txwv rau smelting. Qhov kub ntawm cov hlau molten yog tswj ntawm 1450-1500 degree, thiab cov ntsiab lus ntawm cov ntsiab lus xws li carbon, silicon, thiab manganese raug kho kom ntseeg tau tias purity ntawm cov hlau molten.
Spheroidizing Kev Kho Mob + Kev Kho Mob Inoculation
Kev kho Spheroidizing: Ntxiv magnesium alloy / tsis tshua muaj ntiaj teb ferrosilicon spheroidizing tus neeg sawv cev; Tom qab nplawm, cov graphite tsim cov duab kheej kheej. Precise dosage yog qhov tseem ceeb.
Inoculation Treatment: Ntxiv ferrosilicon inoculant los kho cov nplej, tiv thaiv embrittlement, thiab txhim kho cov yeeb nkab toughness thiab processability.
Centrifugal Cast
Cov hlau molten uas kho tau yog nchuav rau hauv qhov siab - nrawm tig hlau pwm (800–1200 r / min). Lub zog centrifugal ua rau cov hlau molten ua raws li qhov sib npaug ntawm lub puab phab ntsa ntawm cov pwm, tsim ib lub raj nrog cov phab ntsa tuab. Cov pwm yuav tsum tau preheated rau 200-300℃los tiv thaiv cov hlau molten los ntawm txias sai thiab ua rau tawg.
Cooling thiab Demolding
Lub raj yog demolded tom qab txias mus rau 600-700℃hauv pwm kom tsis txhob deformation tshwm sim los ntawm siab - kub demolding.
Kev kho cua sov (Annealing)
Lub raj yog muab tso rau hauv lub qhov cub annealing, rhuab mus rau 900-950℃thiab tuav rau ib lub sij hawm, ces maj mam txias. Lub hom phiaj yog kom tshem tawm cov kev ntxhov siab sab hauv, txo hardness, thiab txhim kho toughness.
Tshaj tawm -kev ua haujlwm thiab tshuaj xyuas
Sab hauv phab ntsa yog lined nrog cement, thiab sab nrauv phab ntsa yog coated nrog asphalt / epoxy rau kev tiv thaiv corrosion. Cov dej siab, qhov loj me, thiab kev ntsuas metallographic tau ua kom ntseeg tau tias ua raws.
Qhov zoo ntawm centrifugal cam khwb cia
Siab -ceev centrifugal quab yuam ua rau cov hlau molten ua kom muaj zog ua ntu zus los ntawm sab nraud hauv, tshem tawm cov pa roj thiab cov khoom sib xyaw ua ke, ua rau me me, sib npaug, thiab sib npaug ntawm cov graphite spheres. Cov yeeb nkab tiav lawm muaj lub zog tensile Ntau dua lossis sib npaug ntawm 420MPa thiab elongation Ntau dua lossis sib npaug li 10%, sib txuas lub zog siab thiab siab tawv. Nws tuaj yeem tiv taus cov av kev sib haum xeeb thiab kev cuam tshuam sab nraud, thiab nws cov khoom tawg yog ntau dua 30% siab dua cov xuab zeb- cov khoom pov tseg.

Uniform phab ntsa thickness, siab qhov tseeb, thiab muaj zog installation adaptability
Los ntawm kev tswj hwm qhov nrawm nrawm, cov yeeb nkab phab ntsa tuab tuaj yeem tswj tau nyob rau hauv ± 1-2mm, ua kom cov phab ntsa tuab zoo sib xws thoob plaws hauv cov yeeb nkab thiab tshem tawm cov teeb meem eccentricity. Qhov no precision guarantees seamless kev twb kev txuas nrog flanges, li qub, thiab lwm yam fittings, txo qhov kev pheej hmoo ntawm installation leaks thiab adapting rau standardized tsim rau txhua txoj kab uas hla specifications ntawm DN80 rau DN2600.

Zoo heev corrosion kuj thiab kev pab lub neej ntev
Cov txheej txheem phab ntsa tuab, ua ke nrog cov cement hauv ob sab phlu thiab ib txheej zinc / epoxy resin txheej los tiv thaiv- txheej txheem corrosion, ua ob txoj kev tiv thaiv. Nrog rau lub neej ntev tshaj 70 xyoo thaum faus hauv av, deb tshaj cov kav dej cam khwb cia, nws txo qhov ntev - cov nqi tu rau cov neeg siv khoom.
04 High efficiency efficiency thiab muaj zog zoo stability
Siv dej-txias hlau pwm centrifugal casting (DMC txheej txheem), cov pwm txias sai heev, ua rau ib qho luv luv - yeeb nkab ua voj voog thiab batch tsim nyog tus nqi ntau tshaj 98%. Tsis xav tau kev rov ua cov xuab zeb pwm, haum rau loj - nplai, cov khoom siv tau zoo, thiab muaj peev xwm ua tau zoo rau lub sijhawm xa khoom ntawm cov khoom loj - ntim xa tawm.
