Ndedzipi mhando dze zvidhinha zvinopesana?

Refractory zvidhinha ndeyemhando dzakasiyana uye zviitiko zvekushandisa. Refractory zvidhinha rudzi rwezvinhu zvinoramba zvine mari shoma yekuita. Vashandisi vanogona kusarudza zvakakodzera zvidhinha zvinoramba zvichienderana nehukuru uye zvakatemwa zvechigadzirwa uye zvakasiyana zvinhu. Ndeapi maitiro emhando dzakasiyana, regai ndikuzivise kwavari pazasi.

Kambani yedu ine zvidhinha zvinoramba, zvidhinha zvakareruka mullite refractory, zvidhinha zvinorasa zvekugocha kabhoni, zvidhinha zvesilicon-mwedzi, zvidhinha zvinoreruka, uye magnesia carbon refractory zvidhinha.

Mullite lightweight refractory zvidhinha ndeyepamusoro-alumina refractory zvinhu zvine mullite sechikamu chikuru chekristaro. Kazhinji, iyo alumina yemukati iri pakati pe65% ne75%. Kuwedzera kune mullite, iyo mineral inoumbwa nealumina yakaderera inewo chikamu chidiki chegirazi chikamu uye cristobalite; iyo yepamusoro alumina yemukati inewo shoma shoma yecorundum

Kugadzirwa kwekabhoni zvigadzirwa kunonyanya kushandisa ekutanga uye echipiri ekugocha mavira uye graphitization mavira, akaunganidzwa anonzi sekabhoni zvigadzirwa zvekugocha mavira. Zvigadzirwa zveCarbhoni zvinogocha mavira zvinogona kukamurwa kuita batch mavira, mavira anoenderera, mavira ekamuri, mhete dzemhete, tunnel mavira, kilns inotenderera kana mavira ekupikisa zvinoenderana nechimiro uye maitiro ekushanda.

Silika-mold zvidhinha zvakabudirira kuyedzwa-kugadzirwa mukutanga 1990s. Vaimbonzi HMS yakakwirira kupfeka-resisting zvidhinha, uye kupfeka kwavo kupikisa coefficient inodarika kashanu kupfuura iyo yephosphate-bonded high-alumina zvidhinha. Nezvekuumbwa kwayo kwechikamu, inofanirwa kunge iri silicon carbide-mullite zvigadzirwa, zvinonzi sesilicon mortar zvidhinha.

Zvidhinha zvinoreruka zvidhinha zvinowanzoreva zvidhinha zvinoramba zvine density isingasviki 1.3x103kg/m3. Nekuda kwehunhu hwehushoma density, high porosity, low thermal conductivity, good thermal insulation and some compressive simba, lightweight refractory zvidhinha zvakashandiswa zvakanyanya mumidziyo yekupisa kupisa.

Sezvinhu zvinosanganiswa zvinoramba, magnesia-carbon refractory zvidhinha zvinoshandisa iyo yakasimba slag corrosion resistance ye magnesia uye yakakwira yekupisa conductivity uye yakaderera kuwedzera kwekabhoni kutsiva kushomeka kwekupokana kwe magnesia. Inonyanya kushandiswa kwesimbi yemagetsi emagetsi.

Izvo zvataurwa pamusoro apa zvidhinha zvinopikisa zvezvakasiyana zvakasiyana uye zvinhu zvakasiyana zvine mitengo yakasiyana. Kushanda kwezvidhinha zve refractory kuchiri kureba. Inopikisa kupisa kwepamusoro uye abrasion. Zvidhinha zvakanaka zvinoramba zvinogona kushandiswa kwenguva yakareba. Kamwe uye zvachose, mhando yezvidhinha zvinoramba zvinogadzirwa nekambani yedu Yakavimbiswa, yakadzama mitengo yezvinhu inogona kubvunzwa pamhepo, yakagadziridzwa chigadzirwa mhinduro kwauri, uye yakatsaurirwa kukushandira iwe.
