01. Cov yam cuam tshuam rau qhov zoo ntawm Tundish Kho
1. Xoob tundish phab ntsa xoobCasting TundishPhab ntsa mas feem ntau tau los ntawm txoj haujlwm sib cuag ntawm cov tundish phab ntsa thiab hauv qab ntawm tundish. Lub xoob xoob tundish phab ntsa yog manifested hauv ob daim ntawv: ib qho yog tias nws txuas ntev ntev los tsim ib qho chaw tsis xwm yeem; Lwm tus yog tias cov hmoov me me poob los ua ib qho "sluit puab".
Muaj ob qho laj thawj rau kev xoob: ib qho yog tias cov binder volatilizes, ua rau lub zog tag nrho lub zog kom txo, tshwj xeeb tshaj yog cov otertermost; Lwm qhov yog tias cov hmoov zoo uas muaj cov ntawv cob tsis tsis muab qhwv cov lus, uas thaum kawg uas ua rau slag yooj yim. Sib tov sib xyaw ua si cov hmoov nplej nrog cov ntaub ntawv phenian thiab thov nws kom muaj zog qis thiab lub zog nruab nrab ntawm cov khoom qhuav.
Raws li qhov teeb meem ntawm thaj chaw, cov laj thawj rau qhov qis qis ntawm kev kho tundish tundish yog: 1) cov tundish cov khoom siv tsis tau. Qhov kev piv tam sim no yog tsawg, thiab muaj qhov tshwm sim ntawm cov khoom siv hluav taws xob thaum kho cov xuab zeb hauv cov khoom siv qhuav yooj yim rau cais. 2) Lub sijhawm ua co ntawm lub log ntev. Tam sim no, 4 lub cev muaj zog tau siv rau cov log tsheb tundish. Txhawm rau kom nce ntom ntom ntom ntawm cov kab slag, lub sijhawm kev co yog 15 feeb. Txawm hais tias lub ntim ntom ntom ntawm cov khoom siv qhuav hauv cov tundish yog ntau, cov khoom siv qhuav yog nquag yooj yim rau "choj" tshwm sim, ua rau phab ntsa ntawm lub pob kom xoob.
2. Cov kab nrib pleb ntawm lub pob phab ntsa
Cov pob phab ntsa ntawm lub taub hau ntawm cov tundish muaj kab rov tav. Cov tuab tuab ntawm cov khoom siv qhuav ntawm txoj haujlwm no yog 11 0 mm, thiab qhov tob tawg yog 40 hli. Tus neeg sawv cev tseem ceeb yog: Tus neeg sawv cev tso tawm tam sim no tau thov ib zaug, cov khoom siv tsis sib xws, thiab cov khoom siv qhuav}. Cov log tsheb tsim kev teeb meem kev ntxhov siab thaum lub sijhawm nqa txheej txheem, uas nyob rau hauv ua kom ua rau cov nrib pleb. 3. Cov duab ntawm lub sab sauv tsis tau raws li qhov yuav tsum tau ua
Cov txheej txheem kho cov khoom siv tam sim no tsuas yog xav tau qhov ntawd yuav tsum tsis muaj cov khib nyiab hauv nozzle. Thaum lub sijhawm ua haujlwm, cov neeg ua haujlwm tsuas yog siv cov hnab ntim pov tseg kom ntsaws lub tshuab ntsaws. Tsis muaj tus qauv sib koom ua ke, cia ib leeg ua rau cov khib nyiab tsim nyog, uas feem ntau ua rau cov khib nyiab kom nyob twj ywm hauv lub nozzle, thiab cov duab ntawm sab sauv nozzular.
02. Daim ntawv thov ua haujlwm
The quality of the tundish repair is improved from the aspects of optimizing the composition of the tundish dry material, standardizing the material distribution operation, optimizing the vibration and baking process, using the release agent reasonably, and designing the foam plug for the special nozzle of the tundish. Tam sim no, tus nqi tsim nyog ntawm kev hloov pauv tundish tundish tau nce los ntawm cov khoom siv qhuav, txhim kho cov khoom siv los tiv thaiv ua haujlwm, thiab txhim kho cov khoom siv ua haujlwm kom qhuav, thiab txhim kho cov khoom siv ua haujlwm kom qhuav, thiab txhim kho lub ntom ntom ntawm cov khoom siv qhuav. Kev yaig ntawm cov txheej txheem ua haujlwm tau txhim kho kev txhim kho, thiab cov txheej txheem yaig ntawm cov khoom siv ua haujlwm tam sim no ntawm lub neej ntawm tundish thiab tau ntsib cov kev tsim khoom. Kev tshuaj xyuas ntawm kev txhim kho Tundish qhia tias lub zog ntawm cov khoom siv qhuav ntawm cov tundish tau txhim kho vim yog cov khoom xoob vim tsis muaj zog. Teeb meem xws li xoob thiab tawg cov phab ntsa tundish tau daws lawm.
