Brass Investment Casting
Lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm cov kauv nozzle ntawm tooj dag peev casting: tom qab cov kua (los yog slurry) yog tangent thiab collided nrog rau qhov tsis tu ncua me me helical nto, nws dhau los ua cov kua dej me me thiab txau tawm los ua huab cua. Cov qauv tsim tawm los ntawm qhov nkag mus rau qhov hluav taws xob hauv lub qhov hluav taws xob nozzle txo cov coefficient tsis kam mus rau qib qis, tsis thaiv, cov khoom siv yog corrosion-resistant, cov nyhuv atomization yog qhov zoo, thiab kev siv yog yooj yim, yog li cov kauv nozzle yog haum rau ntau txoj haujlwm. Piv txwv li: kev lag luam tshuaj, kev tiv thaiv ib puag ncig, hluav taws xob hluav taws xob, textile thiab ntau lwm yam kev lag luam, tshwj xeeb tshaj yog cov roj flue desulfurization thiab kev lag luam tshem tawm plua plav yog qhov siv dav tshaj plaws. Nws cov corrosion kuj, fogging zog thiab anti-thaiv cov khoom tau txais los ntawm ntau tus neeg siv hauv kev lag luam.
Nta ntawm tag nrho-silica nruab nrab-kub ciab peev casting: 1. Nws muaj peev xwm nrum complex castings ntawm ntau yam alloys, tshwj xeeb tshaj yog nyuaj-rau-machine cov ntaub ntawv xws li high-temperature alloys thiab stainless hlau. 2 Brass peev castings muaj qhov tseeb qhov tseeb thiab qhov chaw tiav, feem ntau mus txog CT4-6, tsuas yog tawm me ntsis machining nyiaj pub rau cov khoom uas xav tau ntau dua, thiab txawm tias qee qhov castings tsuas yog tso nyiaj sib tsoo thiab polishing, tuaj yeem siv yam tsis muaj tshuab.
Tsis yog-kev nqis peev casting feem ntau yog siv rau casting stainless hlau, carbon steel, hlau alloy, tooj dag thiab lwm yam ntaub ntawv. Brass peev cam khwb cia hlau stainless yog ntau: 304 cam khwb cia stainless hlau 316 cam khwb cia stainless hlau 420 cam khwb cia stainless hlau 440 cam khwb cia stainless hlau 630 cam khwb cia stainless hlau.
Melting cov ntsiab lus nyob rau hauv peev casting ntawm tooj dag alloys: nce lub melting kub ntawm cov hlau yuav ua rau nws vapor siab thiab volatilization poob raws li. Hauv kev tsim khoom tiag tiag, feem ntau, qhov kub ntawm qhov melting ntau dua, lub sijhawm ntev dua, cov ntsiab lus tsis hloov pauv, qhov qis dua qhov siab hauv qhov cub, qhov loj dua qhov chaw ntawm lub pas dej molten, thiab qhov phem dua qhov npog, qhov ntau dua. volatilization poob. Aluminium, beryllium, thiab lwm yam. ua ib qho kev tiv thaiv oxide zaj duab xis rau saum npoo ntawm lub pas dej molten, uas tuaj yeem txo qhov poob ntawm cov khoom tsis zoo hauv cov hlau. Brass peev casting thiab smelting khoom muaj kev cuam tshuam ntau dua rau cov hlau volatilization. Feem ntau, induction furnaces muaj tsawg volatilization poob, thaum reverberatory furnaces muaj ntau dua poob.
Cov yam ntxwv ntawm plaub lub plhaub-ua txheej txheem ntawm tooj dag peev casting:
1 Brass peev casting dej iav plhaub: Cov txheej txheem no muaj keeb kwm ntau lawm ze li ntawm 50 xyoo hauv Suav teb. Tom qab ib nrab xyoo ntawm unremitting kev rau siab los ntawm cov npoj yaig nyob rau hauv lub tooj dag peev casting kev lag luam, daim ntawv thov thiab kev tshawb fawb ntawm cov txheej txheem dej iav plhaub tau mus txog theem siab. Tau ntau xyoo, vim yog kev txhim kho ntawm cov khoom siv rov qab lub plhaub refractory thiab nrov thiab siv cov hardeners tshiab, lub zog ntawm dej iav plhaub tau ua ob npaug. Tus nqi qis, lub voj voog luv luv, kev ua haujlwm zoo tshaj plaws thiab cov huab cua permeability tseem yog qhov zoo uas lwm cov txheej txheem shelling tsis tuaj yeem ncav cuag tam sim no.
2 Brass peev casting compound plhaub: Piv nrog rau lub khob iav dej, qhov zoo ntawm cov casting tau zoo heev, qhov roughness ntawm qhov saum npoo yog txo, qhov deg tsis zoo raug txo, thiab kho tus nqi txo. Nws tuaj yeem siv rau cov hlau alloy siab xws li stainless hlau thiab cov hlau tsis muaj cua sov. Lub voj voog ntau lawm yog luv dua li ntawm qhov kub thiab txias-silica sol pwm, thiab zoo ib yam li cov iav dej pwm.
3 Brass peev casting silica sol (tsawg kub ciab) plhaub: Cov txheej txheem no yog raws li lub teb chaws tej yam kev mob, thiab muaj qhov zoo tshaj plaws adaptability thiab superiority thaum casting ntau tshaj 1kg, tshwj xeeb tshaj yog ntau tshaj 5kg castings. Piv nrog rau lub plhaub sib xyaw, qhov zoo yog qhov ruaj khov dua, tshwj xeeb tshaj yog cov casting muaj qhov tseeb qhov tseeb, vim nws tsis muaj iav dej, thiab lub plhaub muaj qhov kub thiab txias. Nyias-walled qhov chaw, me me thiab nruab nrab qhov chaw nrog cov qauv complex, thiab ntxiv-loj qhov hnyav hnyav 50-100kg, xws li cov twj tso kua mis, impellers, coj casings, twj tso kua mis lub cev, pob valve lub cev, valve phaj, thiab lwm yam. Rau nyias-walled me me, nruab nrab los yog loj qhov chaw, diav rawg plhaub los yog nqa shells yuav siv tau ncaj qha casting nyob rau hauv pem hauv ntej ntawm lub cub tawg, uas guarantees ib tug siab yield.
4 Brass peev casting nruab nrab kub ciab tag nrho silica sol plhaub: Qhov no yog cov txheej txheem ntau lawm precision casting ntawm lub tshuab. Nws muaj qhov zoo ntawm casting zoo thiab tsis tshua muaj nqi kho, tshwj xeeb tshaj yog tsim nyog rau siab roughness yuav tsum tau thiab dimensional raug. Siab, nruab nrab thiab me me thiab ntxiv me me (2-1000g). Txawm li cas los xij, vim cov khoom siv thiab cov nqi txwv, nws siv tsawg dua (5-100kg).
