5.1.5 Khoom siv:
Cov khoom siv rau kev tsim khoom yuav tsum raug xaiv tsim nyog raws li lawv cov kev xav tau siv, suav nrog kev ua haujlwm thiab ua raws li lawv cov qauv zoo.
Cov khoom siv feem ntau siv rau cov khoom siv hlau thiab lawv cov khoom siv hluav taws xob tso cai thiab kev ua haujlwm siab tshaj plaws yog qhia hauv Table 1.
Qhov siab tshaj plaws tso cai rau saum npoo ntawm cov khoom siv feem ntau rau cov khoom siv hlau hauv cov khoom siv feem ntau yuav tsum ua raws li cov kev cai ntawm Table 2.
Rwb thaiv tsev filling cov ntaub ntawv yuav tsum tau xaiv raws li qhov kub thiab txias ntawm cov khoom. Thaum qhov kub thiab txias ua haujlwm T Tsawg dua los yog sib npaug li 400 degree, sau nrog qis-kub magnesium oxide hmoov; Thaum ua haujlwm kub yog 400 degree ＜ T Tsawg dua lossis sib npaug li 600 degree, sau nrog nruab nrab kub magnesium oxide hmoov; Thaum ua haujlwm kub yog 600 degree ＜ T Tsawg dua los yog sib npaug li 850 degree, sau nrog kub kub magnesium oxide hmoov. Rau cov khoom uas muaj qhov kub siab tshaj plaws siab tshaj 450 degree lossis qhov kub thiab txias uas yuav raug ntsib thaum lub sijhawm ua haujlwm ntau tshaj 450 degree, tooj dag txhuas tawm cov pas nrig yuav tsum tsis txhob siv.
Cov ntaub ntawv zoo sib xws thiab cov yam ntxwv nruab nrab thiab qhov siab tshaj plaws ua haujlwm kub ntawm hluav taws xob cua sov cov qauv 5.1.5 Cov ntaub ntawv:
Cov khoom siv rau kev tsim khoom yuav tsum raug xaiv tsim nyog raws li lawv cov kev xav tau siv, suav nrog kev ua haujlwm thiab ua raws li lawv cov qauv zoo.
Cov khoom siv feem ntau siv rau cov khoom siv hlau thiab lawv cov khoom siv hluav taws xob tso cai thiab kev ua haujlwm siab tshaj plaws yog qhia hauv Table 1.
Qhov siab tshaj plaws tso cai rau saum npoo ntawm cov khoom siv feem ntau rau cov khoom siv hlau hauv cov khoom siv feem ntau yuav tsum ua raws li cov kev cai ntawm Table 2.
Rwb thaiv tsev filling cov ntaub ntawv yuav tsum tau xaiv raws li qhov kub thiab txias ntawm cov khoom. Thaum qhov kub thiab txias ua haujlwm T Tsawg dua los yog sib npaug li 400 degree, sau nrog qis-kub magnesium oxide hmoov; Thaum ua haujlwm kub yog 400 degree ＜ T Tsawg dua lossis sib npaug li 600 degree, sau nrog nruab nrab kub magnesium oxide hmoov; Thaum ua haujlwm kub yog 600 degree ＜ T Tsawg dua los yog sib npaug li 850 degree, sau nrog kub kub magnesium oxide hmoov. Rau cov khoom uas muaj qhov kub siab tshaj plaws siab tshaj 450 degree lossis qhov kub thiab txias uas yuav raug ntsib thaum lub sijhawm ua haujlwm ntau tshaj 450 degree, tooj dag txhuas tawm cov pas nrig yuav tsum tsis txhob siv.
5.1.6 Kev tsim kho:
5.1.6.1 Thaum tsim cov khoom, cov yam ntxwv xws li thermal expansion, yaig, oxidation, thiab creep yuav tsum tau muab rau hauv kev txiav txim siab kom tsis txhob cuam tshuam los ntawm deformation thaum lub sijhawm ua haujlwm ib txwm muaj.
5.1.6.2 Kev tsim qauv ntawm cov khoom siv sab hauv yuav tsum xyuas kom meej tias cov khoom siv xaiv los tsim cov khoom tsis raug puas tsuaj ntawm qhov kub siab tshaj lossis qhov kub siab tshaj plaws uas yuav raug ntsib thaum ua haujlwm, thiab tseem tuaj yeem ua haujlwm tau zoo.
Lub vuam qauv tsim ntawm cov khoom yuav tsum ua raws li cov qauv tsim. Lub vuam seams ntawm cov khoom siv siab, tshwj xeeb tshaj yog cov khoom hauv lub thawv, yuav tsum raug txo kom tsawg thiab txoj hauj lwm ntawm cov vuam seams yuav tsum yooj yim los xyuas.
5.1.6.4 Kev tsim ntawm lub plhaub thiab cov khoom siv ntawm cov kabmob siab yuav tsum ua raws li cov qauv tsim nyog
5.1.6.5 Rau cov khoom uas muaj kauv fins ntawm ob qhov kawg, cov kauv fins yuav tsum tau npog tag nrho cov cua sov ntev ntawm cov khoom raws li axis. Lub puab txoj kab uas hla ntawm cov kauv fins yuav tsum tau sib phim nrog lub sab nraud txoj kab uas hla ntawm cov hlau raj ntawm lub Cheebtsam, thiab ob kawg yuav tsum tau welded rau cov hlau raj phab ntsa.
5.1.6.6 Cheebtsam (nrog rau qhov xaus) yuav tsum tau muab kaw
Lus Cim: Yog tias muaj kev pom zoo, kev ntsuas kev sib khi ib ntus lossis tsis muaj kev sib khi tuaj yeem siv thaum kawg, thiab qhov kev sib khi ntawm qhov kawg yuav tsis raug ntsuas.
5.1.6.7 Cheebtsam siv rau cua sov corrosive media yuav tsum tau ua los ntawm corrosion-resistant hlau hlab los yog muaj lub tes tsho tiv thaiv kom ntseeg tau lub neej kev pab cuam ntawm lub Cheebtsam.
