izvo zvidhinha zvinopesana anoshandiswa muzvitofu zvinopisa?

Refractory zvidhinha zvehot blast stoves zvinosanganisira zvidhinha zvevhu, silica zvidhinha, uye high-alumina refractory zvidhinha (kusanganisira mullite zvidhinha, sillimanite zvidhinha, andalusite zvidhinha, kyanite zvidhinha, uye corpus callosum zvidhinha). Izvo zvinodikanwa zvechitofu zvinopisa zvezvidhinha zvinoramba ndezvi: mwero wakaderera wekukwira, kunaka kwesimba rekushisa kwepamusoro, uye kunaka kwekupisa kwekutyisa. Pamusoro pekusangana nezvinodiwa pamusoro apa, zvidhinha zvecheki zvezvitofu zvinopisa zvinofanirwa kunge zvine huwandu hukuru hwekupisa. Kuti usarudze zvidhinha zvinoramba zvine musoro mukugadzirwa kwechitofu chinopisa, tinofanira kutanga tanzwisisa kushanda kwezvidhinha zvinoramba. Nekuti kwakaringana refractory zvinhu hunhu paramita ndiyo hwaro hwekuona kwayo uye yakavimbika dhizaini.

Hupenyu hwesevhisi hwechitofu chinopisa chakareba kwazvo, kazhinji chinoda makore gumi-10. Refractories inotakura mitoro inorema nekuda kwehuremu hwavo. Naizvozvo, marefractories ane yakanakisa creep resistance anodiwa kuti ashandiswe pasi pekupisa kwakanyanya. Iyo yakakwirira-yekushisa inokambaira inopikisa yesilica zvidhinha ndiyo yakanyanya kukwirira, uye yakakwirira-tembiricha inokambaira yakaderera kwazvo; inoteverwa ne-high-alumina zvidhinha, zvinosanganisira zvidhinha zvepamusoro-aluminium zvakaitwa ne-high-alumina clinker uye sillimanite minerals, iyo ine yakanaka yepamusoro-yepamusoro inokambaira zvinhu. Iyo iri pedyo nekuumbwa kwayo ndeye mullite, zviri nani kupikisa kwezvinokambaira zvezvidhinha.
