Nzira yekusarudza refractory zvinhu zve simbi inokungurutsa kupisa choto

Simbi inoputika yekupisa choto inowanzoshandiswa kupisa mabheti kana diki simbi ingot yekupisa michina, inonyanya kuumbwa nedenga rechoto, madziro echoto uye pazasi pechoto. Iyo tembiricha yekushanda kwenguva refu yakaderera pane 1400 ℃. Kune anoenderera kana annular kupisa mavira, tembiricha yechoto chega chega inogona kukamurwa muzvikamu zvitatu zvepasi, zvepakati uye nepamusoro tembiricha, uye tembiricha iri 500-800 ℃ uye 1150-1300 ℃ zvichiteerana. , 1200-1300 ℃.

Chikonzero chikuru chekukuvadza kwechigadziko chechoto imhaka yekushanduka kwekushisa kunokonzerwa nekushanda kwepakati uye kuvhara kwechoto, zvichiita kuti deformation uye peeling yevheni yevira; chikonzero chikuru chekukuvadza kwechoto pasi uye mudzi wemadziro echoto ndeyemakemikari anoita pakati pesimbi yakanyungudutswa oxide slag uye zvidhinha. .

Zvinoenderana nemamiriro ekushanda echoto chekudziya, zvinodikanwa kuti usarudze akakodzera refractory zvinhu zvinoenderana nemamiriro ezvikamu zvakasiyana kuti uwane kurongeka kwezvishandiso, kuitira kuti iyo yekudziya yevira yekupisa inogona kuve nehupenyu hurefu uye kuchengetedza simba. Zvadaro, sei kusarudza refractory zvinhu simbi rolling kudziyisa choto:

Mushure meanoda kusvika makore makumi matatu ebudiriro, zvinhu zvekudziisa zvekupisa moto zvino zvave kusanganiswa nerefractory castables + anchoring zvidhinha. Kuvaka kuri nyore, kuri nyore kushanda, uye kwakaderera mumitengo yeinjiniya. Icho chinhu chiri nani chekuvaka kiln yeindasitiri.

01 yakaderera tembiricha zone

Iyo yakaderera tembiricha zone inonziwo preheating zone yesimbi inotenderedza choto. Kupisa kwayo kwekushanda kunowanzo kuve pasi pe1200 ℃. Kushandiswa kwealumina yakakwirira inokandwa neAl2O3 inenge 50-55% inogona kuzadzisa zvizere zvinodiwa zvekushandisa, kana kukanda chiedza kunogona kushandiswa Zvinhu zvinoshandiswa sechigadziko chevira chinogona kuderedza kupisa kwepamusoro kwemadziro evira, kuitira kuchengetedza. simba uye kuderedza kushandiswa.

02Medium uye yakakwirira tembiricha zone

Iyo yakanyanya tembiricha nzvimbo inonzi zvakare yekudziya nzvimbo uye inonyura nzvimbo yesimbi inotenderedza choto. Kupisa kwayo kwekushanda kunowanzo kutenderedza 1200-1350°C. Iyo yakaderera-simende inokandwa ine Al2O3 yemukati inenge 60% inogona kusarudzwa. Iyo mbishi yeyakakandwa inofanirwa kusarudzwa ine tsvina yemukati. Yakaderera zvigadziriso zvinogona kuvandudza mashandiro eiyo inokandwa kunosvika 1350 ℃.

Iyo inokandwa yebasa rekushanda inoda kusarudza nzira yekugadzira yakasanganiswa nezvidhinha zveancho. Izvo zvidhinha zveanchor zvinogona kunge zvakakwirira-aluminium anchor zvidhinha zverudzi rweLZ-55.
