Castables siv txujci
1. Cov khoom siv yuav tsum tau nchuav thiab lub tsev kawm ntawv kom huv si; kev siv lub tshuab yog nyob zoo; cov khoom siv hlau, cov khoom, qhov loj, kev sib tsoo thiab kev vuam siv (tsau) zoo, cov hlau thauj tog rau nkoj siv rau kev them nqi kho mob ntxiv; thiab qhov chaw surrounding refrickory cib thiab lwm cov dej ntub dej ntub dej; kev kuaj ua ntej cov ntawv pov thawj yog tsis muaj txiaj ntsim; dej zoo yuav tsum muaj raws li cov dej haus; qhov saum toj no kev pom zoo thiab xyuas kom meej tias kev tsim kho tsis cuam tshuam.
1. Molding: Nws yog tsim los ntawm steel phaj los yog wood ntoo. Cov hlau phom yog coated nrog tso tus neeg sawv cev. Lub Rooj Tswjhwm Saib cov ntoo yuav tsum raug ntub dej nrog cov xim tsis muaj dej thiab yuav tsum tsis txhob nqos slurry. Nws yuav tsum muaj zog txaus.
2. Khoov Siv: siv ib qho khoom tov yuam kev, ua ntej hliv castable rau hauv lub tshuab, thiab tawm lub hnab yas thiab ncuav rau nws. Sib tov rau 2-3 feeb, ntxiv dej rau 3-5 feeb, ntxiv dej tsawg, thiab ntxiv dej tsawg. Tus nqi dej yog 7.0-7.5%.
3. Vibrating: Cov khoom pouring rau hauv pwm yuav tsum tau muab tso rau hauv thiab muab tapped tam sim ntawd nrog lub vibrating pas nrig. Nws yuav tsum tsis raug leaked thiab vibrated thiab re-vibrated ntawm tib txoj hauj lwm kom tsis txhob segregation thiab qhov hauv castable. Tus castable castable yuav tsum muab pov tseg tsis pub dhau 20-30 feeb los ntawm qhov sib ntxiv ntawm dej mus rau qhov kawg ntawm kev siv. Lub pob zeb txuas ntxiv yog tsim los rau sab laug.
4. Txij Nkawm: Tom qab lub nplhaib ntawm qhov castable qhuav, nws tuaj yeem tawm nrog 70% lub zog. Lub sij hawm poob pwm yog ≥ 24 xuab moos, thiab lub sij hawm kho kom zoo yog ≥ 24 teev.
5. Kom Qhuav: Raws li cov qib sib txawv thiab cov thickness ntawm castable hauv ob sab phlu thiab cov xwm txheej ntawm qhov chaw, tus neeg siv lub sij hawm txaus xyuas sij hawm kom paub tseeb tias cov dej tsis tawm. Yuav tsum tau saib xyuas lub sij hawm muaj ❑ 72 teev
Qhov thib ob, ceeb toom:
1. Ntshav tswj tus nqi dej ntxiv. Kev tsim kho kub nyob rau lub caij ntuj no yog siab tshaj 5 ° C, thiab muaj qee qhov kev tiv thaiv tsis pub muaj kev tiv thaiv.
2, siv ib qho kev tov khoom tov, tov khoom sib tov yog txwv tsis pub ua.
3, thauj tog rau nkoj ntxiv rau sab nrauv ntxiv lossis txhuam asphalt xim.
4. Cov khoom no txwv tsis pub muab sib xyaw nrog lwm cov ntawv pov thawj.
5, lub sijhawm tshwj xeeb yog lub Peb Hlis
