Cov neeg siv khoom hauv Spain tau xaj 58 tons refractory alumina cib
Lub Kaum Ib Hlis. 58 tons refractory alumina cib tau ntim rau xa mus rau cov neeg siv khoom hauv Spain. High quality refractory hluav taws cib hauv Topower Refractory.
Txhawm rau txo qhov pores ntawm siab tshwj xeeb Alumina cib thiab txhim kho qhov zoo ntawm aluminium cib, lub siab molding yuav tsum tau txhim kho. Rau qhov zoo tib yam siab tshwj xeeb Alumina cib, lub siab molding yuav tsum ncav cuag 137MPa, thiab molding siab ntawm high-density thiab siab aluminium bricks yuav tsum nyob rau hauv qhov ntau ntawm 176 ~ 215MPa. Hauv lwm lo lus, cov nyhuv no tsuas yog ua tiav los ntawm kev siv ntau tshaj 250T kev sib txhuam nias lub tshuab cib. Lub pores ntawm siab aluminium bricks yuav tsum tau raws li cov hauv qab no: high aluminium cib<21%; 23%of high aluminum bricks such as Ⅱ; III high Special Alumina bricks <22%. Before forming, check the model size. Ordinary high -aluminum brick model setting rate: 1.5%in the upper part; 3.0%in the middle and lower pressure surfaces; 1.5%of the non -accepted surface.
Yuav ua li cas kom qhuav lub siab aluminium cib? Tom qab tsim, cov ntsiab lus ntawm cib dilute feem ntau yog ntau tshaj 3.5 feem pua. Nws tsis tuaj yeem raug rho tawm tam sim ntawd hauv qhov cub. Lub tshuab ziab khaub ncaws ntawm lub cev sib txawv nyob ntawm txoj kev molding ntawm lub cev thiab ib qho hnyav. Lub cev tsim nrog ib tug semi-dry txoj kev yuav tsum tau qhuav nyob rau hauv lub qhov taub tshuab ziab khaub ncaws. Qhov kub ntawm cov cua kub yog 140 ~ 160 ° C, cov pa cua kub yog 60 mus rau 90 ° C, thiab cov dej seem ntawm lub cev dawb paug yuav tsum tsawg dua 2 feem pua. Siv tes-puab molding, cua rauj, thiab kev co los tsim lub cev kom qhuav lawm. Nws lub sij hawm ziab nws txawv ntawm ib qho hnyav. Rau ib lub cev nrog ib qhov hnyav tsawg dua 10kg, nws tuaj yeem qhuav qhuav los ntawm 16 txog 24h; lub cev ntawm 10 mus rau 25kg, ib txwm qhuav 36 mus rau 40h, rau ib qho hnyav ntawm 25 mus rau 40kg, ib txwm qhuav 72 txog 96H. Lub cev hnyav dua, lub sijhawm ziab ntawm lub ntuj ntev dua. Tom qab lub cev qhuav lawm, nws tuaj yeem nkag mus rau lub tshuab ziab khaub ncaws kom qhuav. Qhov ntsuas kub ntawm lub tshuab ziab khaub ncaws yog 100 ~ 120 ° C; Qhov kub ntawm cov pa tawm yog 60 txog 80 ° C.
Dab tsi yog qhov sib txawv ntawm qhov kub thiab txias tshwj xeeb Alumina cib? Thaum tua lub siab aluminium cib xws li Ⅰand Ⅱ, qhov hluav taws kub kub feem ntau yog 1430 txog 1450 degree C, thiab kev txuag hluav taws xob yog 40h. Thaum tua hluav taws kub aluminium bricks, qhov kub ntawm qhov hluav taws kub yog 1390 ~ 1400 ° C, thiab kev txuag yog 24 mus rau 32h. Yog hais tias siab aluminium bricks xws li ⅠandⅡ raug rho tawm haujlwm nrog qhov cub, qhov kub ntawm qhov hluav taws kub feem ntau yog 1550 ~ 1560 ° C. Cov cua kub ceev txawv ntawm cov khoom siv raw thiab cov khoom. Nyob rau theem qis qis ua ntej 600 ° C, qhov kub yuav tsum maj mam rhuab; qhov kub ntawm 600 txog 1200 ° C tuaj yeem nrawm dua me ntsis; Qhov kub ntawm qhov kub siab tshaj plaws ntawm 1200 ° C mus rau qhov kub siab tshaj plaws yuav tsum tswj qhov kub thiab txias. Lub caij txias yuav tsum tau tswj xyuas thaum lub caij txias. High aluminium cib billet kiln (los yog lub tsheb kiln) feem ntau siv pob khoom. Txhawm rau zam kev nyiag nkas thaum tua, sab-hauv-ib qho kev teeb tsa kuj tuaj yeem siv. Boil nws nrog ib tug inverted nplaim taws kiln. Yog tias nws raug hlawv nrog lub qhov cub, lub siab-aluminium clinker xuab zeb cushion tuaj yeem ua rau ntawm lub txee ntawm lub qhov cub, thiab txheej txheej ntawm lub plhaub mov yog paved ntawm txhua txheej ntawm cib. Txhawm rau kom ruaj khov ntawm cov pob zeb cib, ib txheej ntawm cov cib yuav tsum tau rub ncaj nraim ntawm qhov siab. Qhov siab ntawm cib feem ntau yog 650 txog 1000mm. Ntawm lawv, siab tshwj xeeb alumina cib xws li Ⅰ tuaj yeem siab, thiab cib xws li Ⅰ thiab Ⅱ tuaj yeem qis.
