Thaum cov kws tshaj lij qhia cov silica sol precision casting rau cov hlau raug siab, lawv tsis yog xaiv cov txheej txheem xwb-lawv xaiv qhov kev ntseeg siab. Silica sol peev casting muab ± 0.05 hli qhov ntev kam rau ua, nto tiav mus rau Ra 1.6 μm, thiab ze-net-zoo li kev ncaj ncees rau cov khoom uas ua haujlwm hauv qab 350 bar hydraulic siab lossis 600 ° C thermal cycling. Qhov theem ntawm kev sib xws tsis tshwm sim los ntawm cov chaw tsim khoom lag luam. Nws yuav tsum muaj kev qhuab qhia ntawm cov khoom siv, kev ntsuas kev nruj, thiab kev sib sib zog nqus alloy-tshwj xeeb tshaj yog cov qib cobalt-nickel zoo li AMS 5387 thiab T800.
Vim li cas silica sol - tsis yog dej iav los yog phosphate - yeej rau lub hom phiaj tseem ceeb geometries
Silica sol muaj peb qhov zoo uas tsis tuaj yeem sib tham txog lwm txoj hlua khi: thermal stability siab tshaj 1,100 ° C, xoom alkaline residue tom qab dewaxing, thiab tshwj xeeb pwm plhaub lub zog thaum lub sij hawm high-temperature hlau pouring. Peb tau pom dej-iav castings tawg thaum lub sij hawm tom qab kev kho cua sov thaum cov cua txias tshaj 1.2 ° C / sec. Silica sol shells tuav qhov kev ncaj ncees los ntawm cov voj voog no-tseem ceeb thaum machining piston twj tso kua mis lub tog raj kheej nyob qhov twg phab ntsa thickness variation yuav tsum nyob qis dua ± 0.12 hli hla 320 mm diameters. Lub binder tsis tshua muaj viscosity tseem ua rau rov ua dua ntawm 0.3 hli-dav coolant grooves hauv cobalt alloy nozzles-cov yam ntxwv tsis tuaj yeem ntxiv tom qab nrum yam tsis muaj kev cuam tshuam lub neej qaug zog.
Vertical kev koom ua ke tsis yog lo lus buzz-nws yog tib txoj hauv kev los tswj microstructure kev ncaj ncees
Feem ntau cov neeg muag khoom outsource casting, machining, lossis xov. Qhov ntawd tsim cov qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Kev kho cua sov distors qhov ntev vim hais tias tus neeg teb xov tooj cua sov tsis muaj tus thawj GD&T kos duab. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua theem tshwm sim nyob rau hauv ib lub ru tsev ISO. Thaum peb nrum AMS 5387 twj tso kua mis, peb metallurgists xyuas cov ntaub ntawv raw khoom ua ntej melting. Peb pab neeg CNC tshuab ncaj qha los ntawm lub xeev raws li-cam khwb cia siv fixture-mounted CMM tawm tswv yim loops-tsis rov kho. Nto sib tsoo ua raws li tam sim ntawd tom qab kev ntxhov siab-relieving, xauv hauv flatness li ntawm 0.005 hli hla 450 hli ntev. Qhov kev txuas ntxiv no tshem tawm qhov ua yuam kev - thiab piav qhia tias yog vim li cas 92% ntawm peb lub siab valve lub rooj sib txoos dhau qhov kev sim ua haujlwm thawj zaug.
Kev ua tau zoo tiag tiag hauv ntiaj teb pib nrog cov txheej txheem tshwj xeeb alloy validation
Cobalt-nickel alloys tsis coj zoo li 316 stainless. Lawv ua hauj lwm-hardening tus nqi nce tom qab 15% cov khoom tshem tawm. Lawv cov thermal conductivity yog 30% qis dua cov pa roj carbon steel - yog li txiav cov kua xa tawm yuav tsum ntaus cov cuab yeej-txoj kev sib koom ua ke lossis hauv zos melting tshwm sim. Peb daim ntawv qhia txhua T800 tivthaiv hauv peb lub tsev qiv ntawv txheej txheem: spindle RPMs, pub tus nqi ib ntus, txawm tias lub kaum sab xis ntawm lub taub dej txias. Rau cobalt alloy plugs nrog 0.8 hli phab ntsa thicknesses, peb siv 0.3 hli carbide kawg mills ntawm 18,000 RPM thiab 80 mm/min pub-tsis validated tshaj 127 xeem txiav. Cov neeg siv khoom uas coj peb cov duab kos duab qub feem ntau nug: "Koj puas tuaj yeem tuav ± 0.03 hli ntawm no?" Peb cov lus teb tsis yog theoretical. Nws yog raws li kev ntsuas cov ntaub ntawv los ntawm cov geometry zoo tib yam hauv peb cov ntaub ntawv tsim khoom-xws li winch center shaft roller batch qhov twg CMM cov ntaub ntawv qhia pom 0.022 hli max sib txawv ntawm 1,200 units.
Xaiv lub silica sol precision casting Hoobkas txhais tau tias nug peb lo lus nug
- Lawv puas muaj lawv cov kev kho cua sov thiab ua tiav? Outsourced txheej txheem lwv traceability. Yog tias koj lub hauv paus twj tso kua mis tsis kuaj kev vibration, tus neeg muag khoom puas tuaj yeem ua pov thawj lub caij nyoog tempering - thiab txuas nws mus rau qhov qub yaj ntau?
- Lawv puas tshuab cov yam ntxwv tseem ceeb hauv ib qho kev teeb tsa? Re-fixturing qhia kev sib haum xeeb drift. Saib rau cov chaw nrog ntau lub axis CNC hlwb uas tuav ob qho tib si ntxhib thiab ua tiav dhau yam tsis muaj kev tshem tawm.
- Lawv puas tshaj tawm cov ntaub ntawv tshuaj xyuas tiag tiag - tsis yog "ISO tau lees paub" cov lus thov? Nug rau cov qauv CMM cov ntawv ceeb toom qhia qhov txawv txav tawm tsam GD&T callouts. Ib qhov tseeb silica sol precision casting Hoobkas qhia cov-tsis zais tom qab daim ntawv pov thawj.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb yog rau tag nrho peb. Nws cov kev ua haujlwm sib xyaw ua ke, cov txheej txheem tshwj xeeb ntawm cov ntawv qhia, thiab cov khoom ua tiav tag nrho ua rau nws rov ua tus khub rau North American hydraulic OEMs thiab European oilfield cov khoom lag luam. Qhov tshwm sim? Cov khoom uas ua tau raws li qhov tshwj xeeb-tsis yog ntawm daim ntawv-tab sis hauv kev pabcuam. Raws li casting-machining hybrid complexity nce, qhov sib txawv ntawm "castable" thiab "precision-cast" widens. Tsuas yog vertically aligned, metrology-embedded ua haujlwm txuas nws.
