Casting cov ntaub ntawv nyob rau hauv lub taub hau kiln nyob rau hauv lub taub hau KAB, NYIAS KAB KAB KAB KAB SEFEFE SEEM THIAB PASS KILN qhov ncauj ntawm Caas cov ceg ntau lawm yuav luag tawg. Lub ntsiab yog vim li cas yog tias thaum lub sij hawm thiab kub nyob rau hauv kilno nyob rau hauv lub kilno nyob rau hauv lub kilno hauv cua sov, thiab dej dawb nyob rau hauvRefractorters CastablesCov khoom hloov los ntawm kua rau roj hauv lub sijhawm luv luv, thiab ua ib qho vapor siab ua cov kab kub nce. Thaum cov dej tshem tawm sab hauv cov hauv ob sab phlu tsis muaj qhov cuam tshuam hauv lub sijhawm, nws yuav ua rau muaj kev ntxhov siab nce siab. Thaum cov dej vapor siab sab hauv hauv ob sab hauv los poob tshuav nyiaj li cas, cov kab nrib pleb yuav tev tawm, tev tawm lossis txawm tawg. Rau qhov teeb meem tawg ntawm cov khoom siv cas, Refractory Cov Chaw Tsim Khoom hauv kev lag luam cement feem ntau ntxiv 0.1% rau 0.3% organic fiber ntau los tiv thaiv qhov tshwm sim ntawm kev tawg. Organic fiber melts los yog hlawv thaum txog 160℃los ua cov nplua thiab tusyees faib ua ke thiab nqaim pores. Nws tsim tau cov huab cua sib xyaw ua ke ntawm cov khoom siv hauv ob sab phlu, ua tiv thaiv cov pa dej los ntawm kev hloov kom sai thaum lub sijhawm ua kom sov. Txawm li cas los xij, kev siv ntawm cov organic fiber muaj teeb meem xws li kev cuam tshuam nyuaj ntawm castables, ntxiv ntxiv, thiab lub zog cuam tshuam.
5 cov lus qhia rau kev daws teeb meem tawg
01 Txij li tag nrho cov cement tsim muaj hla kev tsim kho kom zoo thiab kho kom zoo li lub sijhawm ua haujlwm ntawm lub sijhawm ua haujlwm sib xyaw ua ke hauv ntau qhov chaw ntawm cov xis Kiln. Rau cov casab ntawv hauv qee qhov uas nyuaj rau ci (grate txias (grate txias, kiln lub taub hau thiab pem hauv ntej lub sijhawm tsim nyog yuav tsum tau tshwj tseg; Nyob rau tib lub sijhawm, kev saib xyuas ntawm chav ua haujlwm yuav tsum ua kom tiav zoo, thiab kev txij nkawm kev ua tiav, thiab kev saib xyuas ntawm cov khoom siv ua kom nruj raws li cov lus qhia kev tsim kho.
02 Thaum tsim lub taub hau Kiln, nws yog qhov zoo tshaj plaws kom tawm hauv lub qhov. Cov kev tsim nyog tau drilling yog: spacing 300mm × 300 hli, thiab embedded nrog ф5mm ntoo strips, nrog ib tug tob ntawm ib nrab ntawm ib nrab ntawm ib nrab ntawm ib nrab ntawm ib nrab.
03 Tom qab Kiln lub taub hau npog qhib lub qhov yog kaw, 8 vents yuav tsum tau khaws cia thiab waterproofed. Nyob rau tib lub sijhawm, txhawm rau kom ntseeg tau tias cov refractory castable nyob rau hauv pem hauv ntej npuaj lub qhov ncauj tawm thaum lub sijhawm tsim, thiab kev tso sab ntawm lub qhov yog 100 ib square meter.
04 Rau cov nruab nrab thiab kho cov pob zeb kom qhuav, ua ntej siv lub ntsej muag, thiab lub taub hau tshwj xeeb (thiab lub sijhawm ci nrog) thiab lub sijhawm ci mov tsis tsawg tshaj 12 teev. Nyob rau tib lub sijhawm, cov cua sov yuav tsum tsis txhob nrawm nrawm thaum lub rooj txheej txheem. Rau qis -} Maas series Refractory yog tsis tshaj 15℃ib teev, uas tuaj yeem ua tiav cov kev xav tau ntawm cov cua sov hauv ob sab.
05 Thaum tsis muaj sijhawm ci rau kev kho kom xwm ceev los yog lab cov khoom lag luam, xws li PA-852 phosphate castables, tuaj yeem siv. Cov khoom lag luam no muaj qhov zoo dua ntawm kev pub dawb ntawm ci, thiab nws lub zog nce nrog sawv hauv qhov kub. Txawm li cas los xij, nws yuav tsum tau taw qhia tias hom khoom no muaj nws tus kheej tsis muaj zog, xws li hnav tsis zoo thiab lub neej pabcuam tsis zoo. Lub bursting ntawm casts yog qhov teeb meem nyuaj, uas yog ze rau ntau yam, tshwj xeeb thaum kev tsim kho lub caij ntuj no. Xav tau ntau dua yuav tsum tau them nyiaj.
Hauv ntej, ntxiv 0.1% rau 0.3% ntawm tawg {{}}}}}- ntawv ua yeeb yam ntawm cov khoom. Rau cov cheeb tsam muaj kev tawg paj tawg, xws li cov khoom siv ua ntej, thiab cov khoom siv ci ua kom zoo, thiab lub taub hau refstably tau ua tiav, qhov kev tsim kho ntawm ob lub taub hau refractory tuaj yeem ua tiav.
