Kutumirwa Kutsva kweMugadziri Anogadzirisa Mutengesi Mutengo Wakakwirira weAlumina Castable
Tine boka redu rekutengesa zvinhu, boka rekugadzira, vashandi vehunyanzvi, timu yeQC uye boka remapakeji. Iye zvino tine nzira dzakasimba dzekudzora maitiro ese. Zvakare, vashandi vedu vese vane ruzivo mukudhinda mabasa ekudhinda.Inogadziriswa neRefractory uye Inogadziriswa neHigh Alumina, Tichapa zvinhu zviri nani zvikuru zvine magadzirirwo akasiyana-siyana uye masevhisi ane ruzivo. Tinogamuchira zvechokwadi shamwari dzinobva kumativi ese epasi kuti dzishanyire kambani yedu uye dzishande nesu zvichienderana nekubatsirwa kwenguva refu uye kwese kwese.
Zvishandiso zvesimbi zvinoramba zvichichinja-chinjazvinhu zvakagadzirwa zvakasanganiswa kare zvinosanganisira zvinhu zvakasanganiswa zvine hupfu hwakanyanya, hupfu hwakatsetseka, zvinhu zvinosunga zvehunyanzvi, uye zvinhu zvinowedzerwa zvine hungwaru. Nekuwedzera mvura kana zvinwiwa zvakakosha, zvinogona kugadzirwa zviri nyore nekudurura, kudedera, kana kukwesha, uye zvinogonawo kugadzirwa kuita zvikamu zvakagadzirwa nechimiro chakagadzirwa kuti zvikwane zvivakwa zvakaoma zvechoto. Kana zvangogadziriswa, zvinoumba jira rakatsetseka risingapindike rinopfuura zvidhinha zvechinyakare zvinoramba kushanda zvakanaka pakuisa uye kudzora kupisa.
Kare yaizivikanwa sekongiri inopikisaNekuda kwekugadzirwa kwayo kwakafanana, maitiro ekuisa, uye nzira yekuvaka nekongiri yeinjiniya yezvivakwa, machira edu esimbi asingashande akagadziridzwa nemafomula epamusoro kuti ape kushanda kwakanaka munzvimbo dzakaoma dzemaindasitiri.
Kurongwa Kwechigadzirwa
Tinopa mhando dzakasiyana dzezvinhu zvinogadziriswa zvisingashande kuti zvisangane nezvinodiwa zveindasitiri, zvakarongwa nezvinhu, binder, uye mashandiro:
1. Nezvinhu:Zvigadziko zve alumina zvine simba guru, zvigadziko zve alumina-magnesia, zvigadziko zve alumina-silicon carbide-carbon, zvigadziko zvinodzivirira acid, zvigadziko zvinodzivirira alkali, zvigadziko zvinodzivirira kutonhora zvishoma, nezvimwewo.
2. Nebhainda:Zvigadziko zvesimbi zvine calcium aluminate cement bonded, zvigadziko zvesimbi zvine low/ultra-low/no cement, zvigadziko zvesimbi zvine phosphate bonded, zvigadziko zvesimbi zvine silicon sol bonded, nezvimwewo (zvigadziko zvesimbi zvine low/ultra-low cement zvine porosity yakaderera uye simba remuchina rakakwirira).
3. Nekuita:Zvigadziko zvinofamba zvega, zvigadziko zvinoomesa nekukurumidza, zvigadziko zvinoramba kupfekwa, zvigadziko zvinodzivirira kupisa, zvigadziko zvinodzivirira kupisa, nezvimwewo.
Zvakanakira Zvikuru:
1. Kuramba Kunopisa Zvikuru:Inokwanisa kutsungirira tembiricha inosvika 1600-1800°C, ichichengetedza chimiro chayo chisina kuora kana kurasikirwa nezvinhu kunyangwe munzvimbo dzakaoma dzemaindasitiri dzakadai sekunyunguduka kwesimbi uye kugadzirwa kwemagirazi.
2. Kugara Kwepamusoro & Kuramba Kuora:Haiparare, haiparare nemarara akanyungudutswa, uye hairwiswi nemakemikari, inoderedza mari yekutsiva nekugadzirisa nguva nenguva, uye inowedzera hupenyu hwekushanda kwemidziyo yako yechoto zvakanyanya.
3. Kugadzikana Kwakanaka Kwekupisa Kwekupisa:Inogona kutsungirira kuchinja-chinja kwekushisa kamwe kamwe isina kutsemuka kana kupera simba, zvichiita kuti ive yakakodzera michina ine mashandiro anowanzoitwa, senge makironi anotenderera uye madhishi esimbi.
4. Kuvaka Kunochinjika & Kugadzirisa:Yakakodzera kudira maumbirwo akaomarara uye majometri akaomarara, ichichinjika kumagadzirirwo akasiyana-siyana echoto; tinopawo zvikamu zvakagadzirwa kare uye kugadzirisa fomura zvichienderana nemamiriro ako chaiwo ekushanda (tembiricha, mutoro wemakanika, rudzi rwengura).
5. Kushanda Nesimba Nesimba Uye Kuchengetedza Mari:Kushanda zvakanaka kwekudzivirira kupisa kunoderedza kurasikirwa nekupisa, kuderedza kushandiswa kwesimba rekugadzirisa tembiricha; maitiro ari nyore ekuvaka anovandudza kushanda zvakanaka kwekuisa uye anoderedza mari yevashandi; sarudzo dzinogona kudzokororwa dziripo kutsigira kugadzirwa kwakasimba.
6. Kusimba Kwakawedzerwa (Sarudzo):Kuwedzera fiber dzesimbi dzisingatsvi kunowedzera kusimba kwemidziyo munzvimbo dzine simba guru remagetsi; kuwedzera fiber dzisina makemikari kunowedzera kusimba uye kusimba kwekupisa kwemidziyo inokanda zvinhu zvisingatsvi.
