Thaum cov kws tshaj lij hais txog cov kev daws teeb meem ntawm steel casting foundry Hoobkas, lawv tsis yog tsuas yog yuav qhov chaw-lawv tab tom ua kom muaj kev ncaj ncees ntawm cov qauv hauv qab 350 bar hydraulic siab, qhov ruaj khov tom qab 10,000 thermal cycles, thiab metallurgical sib xws thoob 500-unit batches. Tias yog vim li cas "steel casting foundry Hoobkas" tsis yog lub ntsiab lus tshawb fawb - nws yog qhov tseeb lim. Cov neeg yuav khoom hauv cov roj & roj, mobile hydraulics, thiab kev tsim cov twj tso kua mis siab tsis zam qhov kev hloov pauv ntawm lub tog raj kheej lub tog raj kheej phab ntsa thickness, valve rooj hardness, los yog cobalt-alloy nozzle grain qauv. Lawv xav tau cov neeg koom tes uas kho ASTM A216 WCB ua qhov pib-tsis yog qhov kawg.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau nrum ntau tshaj 17,000 hlau thiab stainless hlau Cheebtsam txij thaum 2018-txhua tus raug rau peb-theem tshuaj ntsuam xyuas: raw cov ntaub ntawv pov thawj (kua sov tooj logged), nyob rau hauv-txoj kev CMM pov thawj ntawm tseem ceeb GD&T datums, thiab zaum kawg kev cai. Peb tau pom cov neeg siv khoom tsis lees paub qhov chaw rau ± 0.08 hli bore sib txawv hauv piston twj tso kua mis - tsis yog vim tias daim duab tso cai rau nws, tab sis vim lub ntiaj teb foob extrusion tiag tiag pib ntawm ± 0.05 hli. Qhov ntawd yog qhov tseem ceeb ntawm kev sib koom ua ke ntsug: xuab zeb casting, kev kho cua sov kom txo qis, kev ua tiav CNC ntau lawm, thiab kev ua haujlwm txhua yam tshwm sim hauv ib lub ru tsev ISO 9001-certified. Tsis muaj handoffs. Tsis muaj batch-rau-batch alloy drift. Tsis muaj kev kwv yees ntawm lub zog tensile tom qab machining-induced micro-cracking.
Feem ntau cov hlau casting foundry Hoobkas tsis ua raws li rov qab mus rau ib qho yuam kev: kho casting thiab machining raws li cov txheej txheem cais. Tab sis 420HB stainless hlau valve lub cev machined los ntawm ib tug tsis zoo gated xuab zeb casting tsim residual kev nyuaj siab uas warps sealing nto thaum kawg tig. Peb daws qhov no los ntawm kev sib koom tsim cov rooj sib tham nrog cov cuab yeej siv tshuab-siv simulation los kwv yees kev cuam tshuam ua ntej thawj lub ncuav. Rau AMS 5387 cobalt alloy twj tso kua mis, peb pre-heat pwm rau 220 ° C thiab tswj cov cua txias li ntawm ± 5 ° C / teev kom tsis txhob sigma theem embrittlement. Tom qab ntawd, es tsis txhob rough-machining kub, peb tos 72 teev tom qab cam khwb cia rau tag nrho cov kev ntxhov siab nyem - txiav zaum kawg machining lub sij hawm los ntawm 30% thaum tuav ± 0.03 hli positional kam rau ua ntawm 8-mm txoj kab uas hla nrhiav pins.
Ntawm no yog dab tsi cais txhim khu kev qha steel casting foundry Hoobkas muaj peev xwm los ntawm cov khoom muag:
- Cov ntaub ntawv traceability ci hauv: Txhua T800 cobalt-based Cheebtsam ships nrog zeb xeem ntawv ceeb toom, kho cua sov cav, thiab spectral tsom xam-txuas mus rau nws tshwj xeeb QR-coded ntau ID
- GD & T-ua ntej kev tsim khoom: Peb validate drawings rau manufacturability * ua ntej * quoting-flagging tsis yooj yim sua callouts zoo li "qhov tseeb txoj hauj lwm Ø0.05 hli txheeb ze rau datum B, uas yog ib tug uas tsis yog-machined casting nto"
- Hybrid txheej txheem mastery: Xuab zeb casting rau tej geometry + peev casting rau nyias-walled nozzles + CNC rau qhov chaw ua haujlwm-tag nrho optimized rau tib tsev neeg
- Tsis muaj "standard" alloys tsis muaj validation: Peb WCB castings ua tau raws li ASTM A216 * thiab * dhau mus kuaj ultrasonic ib ASTM E186 rau cov ntu tseem ceeb> 50 hli tuab
Qee qhov xav tias stainless hlau castings cia li tiv thaiv corrosion. Tab sis peb tau sim 316 stainless vaj tsev nyob rau hauv ib puag ncig roj qaub-thiab pom pitting pib nyob rau hauv 48 teev thaum chromium segregation tshaj 0.3% hla dendrite caj npab. Tias yog vim li cas peb tau txais ntawv pov thawj 316 ingots nrog ≤0.02% leej faj thiab ua qhov kev ntsuam xyuas kev sib xyaw ua ke ntawm ASTM A262 Xyaum E ntawm txhua qhov cua sov. Thaum cov neeg siv khoom nyob sab Europe xav tau winch center ncej rollers rau offshore cranes, peb tau hloov los ntawm 4140 mus rau ASTM A487 Qib CA6NM stainless-ntxiv 22% qaug zog lub neej ntawm 120 ° C ua haujlwm kub, txheeb xyuas los ntawm 500,000-cycle torsional kuaj.
Kev cia siab nyob rau hauv steel casting foundry Hoobkas tso zis tsis ua tiav los ntawm nruj tolerances ib leeg. Nws tau tsim rau hauv cov txheej txheem xaiv cov khoom siv, gating tsim physics, kev kho cua sov so lub sij hawm, thiab kev soj ntsuam nruj. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb ntsuas kev ua tiav los ntawm xoom teb tsis ua haujlwm ntawm lub siab li qub tau siv rau hauv North American fracking fleets - thiab los ntawm kev xaj rov qab los ntawm cov neeg Esxias sab hnub tuaj twj tso kua mis OEMs uas tshuaj xyuas peb cov txheej txheem txhua 18 lub hlis. Lub tuam txhab steel casting foundry koj xaiv yuav tsum kho koj cov khoom tsis yog casting, tsis yog machined ib feem, tab sis raws li ib tug system-tseem ceeb interface ntawm kua zog thiab mechanical zog. Qhov ntawd xav tau ntau tshaj li cov khoom siv. Nws xav tau cov ntaub ntawv kev qhuab qhia, kev lav phib xaub ntawm metallurgical, thiab txaus siab hais tias "tsis yog" rau daim duab ua ntej hais tias "yog" rau hnub xa khoom.
