Wb tham txog xuab zeb casting stainless hlau. Muaj coob tus neeg hnov stainless hlau thiab tam sim ntawd xav precision, xav peev casting, xav smooth finishes. Xuab zeb casting tau sidelined raws li cov ntxhib, qias neeg npawg. Qhov ntawd yog qhov yuam kev. Nws yog ib txoj kev siv tau zoo kawg nkaus rau ntau yam ntawm cov khoom, tab sis koj yuav tsum paub nws cov lus. Lub rooj vag system tsim, cov xuab zeb muaj pes tsawg leeg-tshwj xeeb tshaj yog rau cov alloys-nws yog ib tug tsiaj nyaum sib txawv ntawm casting grey hlau. Koj tsis tuaj yeem tsuas yog ncuav 304 rau hauv cov zaub ntsuab thiab pwm tsim los rau manhole npog thiab cia siab tias yuav ua khawv koob. Lub fluidity yog txawv, lub shrinkage yog txhoj puab heev, thiab yog hais tias koj tau txais lub txias tsis ncaj ncees lawm, koj nyob nraum xauv hauv kev ntxhov siab los yog phem, tsim loj heev kua muag uas tsuas tshwm sim tom qab machining. Kuv twb pom lawm. Ib tus neeg siv khoom ib zaug tau hais rau lub cev loj, nyuaj ntawm lub cev ntawm cov xuab zeb pov tseg, tawm tsam cov lus qhia. Qhov tshwm sim? Ib qho zoo nkauj-zoo li casting uas tawg nyob rau hauv nws tus kheej thermal stress thaum lub caij txias. Nws ntsia zoo tag nrho ntawm qhov chaw, tab sis nws yog seem. Qhov ntawd yog qhov khoom nrog xuab zeb casting stainless: cov npoo rau kev ua yuam kev hauv cov txheej txheem tsim yog nyias.
Cov ntaub ntawv tsis sib haum xeeb
Yog li vim li cas qhov kev tsis ncaj ncees? Kuv xav tias nws los ua kom tiav thiab precision. Kev nqis peev casting, plhaub molding-lawv muab rau koj nyob ze-net-puab qhov chaw, qee zaum npaj rau kev sib dhos nrog kev ua haujlwm tsawg. Xuab zeb casting muab rau koj ib tug ntxhib dawb paug, feem ntau nrog ib tug hnyav tag nyiaj pab. Rau ntau lub ntim siab, me me stainless qhov chaw, uas yog khib nyiab. Koj tab tom them rau tshuab tshem ntau yam khoom kim heev. Tab sis qhov twg xuab zeb casting ci yog nyob rau hauv ib-offs, cov qauv, qhov tsawg-ntim loj qhov chaw.

Nws yog ib qho ntawm cov teeb meem zoo uas cais ib qho chaw tsim nyog los ntawm ib qho zoo.
Tom qab Casting: Kev Ua Haujlwm tiag tiag feem ntau pib
Nov yog lwm qhov kev kuaj xyuas qhov tseeb. Thaum lub casting tawm ntawm lub shakeout, koj txoj hauj lwm yog ib nrab ua tiav. Koj yuav tsum tau txiav tawm lub rooj vag thiab risers, uas ntawm stainless yog tawv. Plasma arc lossis abrasive txiav yog tus qauv. Tom qab ntawd muaj kev kho cua sov. Feem ntau cov xuab zeb-cam khwb cia hlau stainless Cheebtsam yuav xav tau cov tshuaj annealing kho. Qhov no suav nrog cua sov rau ib puag ncig ° C, tuav, thiab tom qab ntawd quenching sai hauv dej lossis huab cua. Qhov no dissolves cov chromium carbides uas tsim thaum lub sij hawm qeeb qeeb hauv pwm (uas tuaj yeem ua rau muaj kev kub ntxhov thiab teeb meem corrosion) thiab txo cov kev ntxhov siab sab hauv. Kev hla cov kauj ruam no yog ib qho kev ua yuam kev loj heev rau cov khoom siv rau kev pabcuam corrosive.
Tom qab kho cua sov, koj feem ntau pom muaj kev cuam tshuam. Casting warps. Nws yuav luag guaranteed. Tias yog vim li cas koj tso qhov nyiaj pub dawb machining. Qhov no yog qhov kev koom tes nrog lub khw muag khoom yog qhov tseem ceeb. Lub tuam txhab uas ua ob qho tib si casting thiab machining, zoo li QSY, muaj qhov zoo dua. Lawv paub yuav ua li cas ib feem yuav txav los ntawm kev kho cua sov, lawv paub qhov twg yuav tawm hauv Tshuag ntxiv, thiab lawv tuaj yeem kho nws kom raug rau machining. Sim kom tau txais cov xuab zeb xuab zeb los zaum hauv CNC vise ntawm lub khw muag khoom tsis sib xws yog ib daim ntawv qhia rau cov khoom seem thiab cov lus sib cav.
NDT yog lwm qhov tseem ceeb, thiab feem ntau underestimated, kauj ruam. Rau cov khoom siv siab, kev kuaj hluav taws xob (RT) lossis kuaj ultrasonic (UT) tau teev tseg. Tab sis rau ntau qhov chaw ua lag luam, qhov zoo dye penetrant test (PT) yog qhov tsawg kawg nkaus los kuaj xyuas qhov tawg lossis qhov porosity. Cov rooj vag thiab riser cov ntsiab lus sib cuag yog thawj qhov chaw pib tawg. Koj zom lawv yaug, ces PT. Kuv tsis tuaj yeem suav pes tsawg zaus uas zoo li zoo meej casting pom cov plaub hau tawg ntawm lub caj dab riser tom qab PT. Nws yog ib qho tsim nyog, txo hwj chim kauj ruam.
