Saib, poob ua npuas ncauj casting. Nws yog ib qho ntawm cov txheej txheem uas tau txais ntau lub buzz rau nws lub peev xwm - ze-net duab, complex geometries, txo machining. Tab sis taug kev mus rau hauv kaum qhov chaw thov kom ua nws, thiab koj yuav pom kaum sib txawv ntawm kev ua tiav. Qhov loj tshaj misconception? Tias nws tsuas yog ib qho kev ntxuav kom huv rau cov xuab zeb casting. Tsis yog. Nws yog ib qho ua tiav, thiab yog tias koj cov qauv ua npuas ncauj, txheej, xuab zeb compaction, thiab qhov rooj tsis nyob hauv ib qho kev ua las voos zoo meej, koj tsuas yog hlawv cov khoom kim heev polystyrene los ua cov khoom seem. Kuv tau pom ntau qhov kev sim ua tsis tau zoo los ntawm cov neeg kho cov qauv ua npuas dej zoo li nws yog pov tseg es tsis yog qhov tseem ceeb ntawm cov txheej txheem.
Qhov Ua-lossis-Tso Pib Pib: Tus Qauv Nws tus kheej
Txhua yam hinges ntawm tus qauv ua npuas ncauj. Nws tsis yog ib qho duab xwb; nws yog ib tug volatile placeholder. Peb kawm qhov no nyuaj heev thaum ntxov. Kev muag khoom pheej yig, tsis tshua muaj EPS hlaws yuav txuag tau tus nqi ua ntej, tab sis cov hlaws fusion kab dhau los ua cov ntsiab lus tsis ua haujlwm. Cov npuas dej yuav tsum tau tuab txaus los tuav tuav yam tsis muaj denting, tab sis txhua gram ntxiv yog roj ntim thaum lub sij hawm nchuav, cuam tshuam cov hlau ntws thiab kev ncaj ncees kawg. Cov qauv sib dhos-gluing ntau ntu ua npuas ncauj-yog lwm tus neeg tua neeg uas ntsiag to. Siv cov nplaum tsis raug, thiab nws tsis yog qhov sib koom ua ke (ua rau cov hlau nkag mus rau hauv cov seam, qhov tsis zoo hu ua veining) lossis nws tawm ntawm cov khoom seem carbonaceous uas ua rau muaj kev cuam tshuam. Peb hloov mus rau ib qho tshwj xeeb kub-kua nplaum nplaum rau cov pob qij txha tseem ceeb tom qab ib pawg ntawm lub cev valve ua tsis tiav ntawm flanges. Nws yog cov minutiae uas cais cov qauv los ntawm kev tsim khoom-npaj zoo.
Tom qab ntawd muaj txheej txheej, refractory slurry. Qhov no tsis yog xim; nws yog ib qho barrier thiab permeability controller. tuab heev, thiab cov pa roj los ntawm vaporizing ua npuas ncauj tsis tuaj yeem khiav ceev txaus, ua rau cov hlau kaw lossis txawm tshuab rov qab. Nyias heev, thiab cov xuab zeb tawg, tsim kom muaj ib qho ntxhib, fused nto tiav. Lub viscosity xav tau kev saib xyuas tas li - qhov kub thiab av noo hauv lub khw cuam tshuam nws heev. Peb tsom rau cov txheej txheej uas dries rau daim tawv nqaij zoo li ceramic, tawv txaus rau cov xuab zeb txhaws tab sis nkig txaus kom tawg hauv qab cov hlau pem hauv ntej kom tso pa tawm. Nws yog qhov sib npaug uas koj xav tias, qhov tseeb, los ntawm nws li cas nws drips ntawm koj tus ntiv tes.
Kuv nco qab txog qhov project rau lub tsev twj tso kua mis compact, ib txoj hauj lwm sab hauv txoj kev. Cov neeg siv xav tau nws hauv cov hlau nplaum. Thawj qhov kev khiav yog kev puas tsuaj-shrinkage porosity pawg hauv cov ntu tuab. Ua npuas ncauj, ntawm chav kawm, ploj mus thiab tawm tsis muaj cov ntsiab lus thermal. Qhov teeb meem yog tias peb lub rooj vag, theej los ntawm txoj kev xuab zeb casting, tsis suav rau qhov kub ntxiv los ntawm kev ua npuas ncauj endothermic decomposition. Peb yuav tsum tau rov tsim kho cov txheej txheem pub mis tag nrho, ntxiv cov risers ntau dua hauv qhov chaw tsis yog ib txwm ua kom them nyiaj rau qhov txias txias. Nws ntxiv machining kov cov ntsiab lus tom qab, tab sis nws yog qhov ntawd lossis seem. Cov qauv yog cov khoom, kom txog rau thaum nws tsis yog.
Xuab zeb, kev vibration, thiab Illusion ntawm Simplicity
Qhuav, unbonded xuab zeb. Suab yooj yim. Tab sis nws compaction nyob ib ncig ntawm lub cev tsis taus, coated qauv yog qhov uas feem ntau pom qhov tsis xws luag yug. Lub rooj vibration yog lub plawv ntawm nws. Koj xav tau ntau txoj kev vibration kom tau cov xuab zeb ntws mus rau hauv txhua qhov kab noj hniav yam tsis muaj dislodging lossis distorting tus qauv. Kev txhoj puab heev, thiab koj tuaj yeem txiav cov phab ntsa nyias los yog ua rau cov txheej txheem tawg ua ntej. Yooj yim heev, thiab koj tau txais cov pob muag hauv cov xuab zeb, ua rau pwm phab ntsa txav thiab qhov tsis raug ntawm qhov tsis raug - qhov peb hu ua bulging.
Peb khiav ib qho kev sib xyaw ntawm silica xuab zeb, tab sis rau qee qib stainless hlau peb tau tsiv mus rau zirconia rau nws cov thermal stability dua. Qhov tseem ceeb yog qhov sib xws. Txhua yam dej noo yog yeeb ncuab; nws reacts nrog cov hlau kub thiab decomposing ua npuas ncauj los tsim chav hnab ris, ua rau pinholes. Peb qhuav cov xuab zeb hauv lub tshuab ziab khaub ncaws yog tias muaj cov av noo. Nws yog ib kauj ruam ntxiv, tab sis nws yog pheej yig dua li kev kho cua sov tag nrho tom qab sim thiab kaw qhov porosity uas koj tsis tuaj yeem pom ntawm qhov chaw.
Lub ncuav nws tus kheej yog anti-climactic tab sis tense. Koj tab tom nchuav hlau mus rau qhov tseem ceeb roj. Tus nqi yog qhov tseem ceeb. qeeb dhau, thiab cov npuas dej degrades ua ntej ntawm cov hlau pem hauv ntej, ua rau cov kab noj hniav tawg los yog cov xuab zeb poob rau hauv. Ceev dhau, thiab cov roj hluav taws xob overwhelms cov txheej txheej permeability, ua rau turbulence thiab slag inclusions. Koj saib cov vents rau cov pa luam yeeb, xim thiab ntws ntawm nws qhia koj yog tias qhov kub hnyiab tau huv. Ib tug dub, oily pa luam yeeb txhais tau tias tsis tiav combustion, teeb meem. Ib tug khov kho, greyish-dawb plume yog qhov koj xav tau. Nws yog ib tug heev sensory txheej txheem.
Qhov twg nws haum thiab qhov twg nws tsis
Poob ua npuas ncauj casting ci rau tej tsev neeg ntawm qhov chaw. Lub cav thaiv, lub tog raj kheej taub hau, manifolds - cov duab nyuaj nrog cov kab lus sab hauv uas yuav xav tau cov xuab zeb nyuaj thiab kim kim. Kev tshem tawm cov tub ntxhais sib dhos thiab cov ntawv luam tawm tseem ceeb yog kev txuag nyiaj ntau hauv kev ua haujlwm thiab txhim kho qhov sib xws. Rau ib lub tuam txhab xws li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog ntau xyoo hauv lub plhaub thiab peev casting, ntxiv ua npuas ncauj poob rau cov ntaub ntawv yog hais txog muab cov txheej txheem rau txoj cai geometry. Qee zaum, ib feem peb hais tuaj yeem ua los ntawm plhaub pwm lossis ua npuas ncauj ploj. Lub breakpoint feem ntau yog internal complexity thiab ntim.
