Zvinhu zvitatu zvekukwira kwekushisa kwepamusoro kwezvinhu zvinodzivirira
Zvinhu zvitatu zvekukwira kwekushisa kwepamusoro kwe refractory zvinhu
Mukuyedzwa kwezvinhu zvinoramba, kukwira kwekushisa kwakanyanya ndechimwe chezviratidzo zvakakosha zvekuongorora mashandiro uye kunaka kwezvinhu zvinoramba. Hukama huri pakati pe deformation uye nguva yezvinhu zvinoramba zvichidzika pasi pekushisa kwepamusoro uye imwe mutoro ndeyekukwira kwekushisa kwezvinhu. Kana chinhu chikaiswa kune imwe mutoro pasi pesimba rayo rekupedzisira pakupisa kwakanyanya, deformation yepurasitiki inozoitika, uye deformation yayo ichawedzera zvishoma nezvishoma nekufamba kwenguva, uye kunyange kukuvadza zvinhu. Iyi mhando yezvinokambaira chiitiko pasina mubvunzo inonyanya kukosha pakushandiswa kwezvinhu zvinoramba, nekuti zvinhu zvitatu zvezvinhu zvinoramba zvinotariswa panguva imwe chete yezvigadzirwa zvinoramba pakushisa kwepamusoro: simba, tembiricha uye nguva.
Nekuda kwenzira dzakasiyana dzemutoro dzinoshandiswa kune zvinodzoreredza zvinhu, inogona kupatsanurwa kuita yakakwirira-tembiricha yekumanikidza inokambaira, yakakwirira-tembiricha inokambaira, yakakwirira-tembiricha inoshanduka inokambaira uye yakakwirira-tembiricha torsional inokambaira. Pakati pavo, high-temperature compression creep (inonzi compression creep) inowanzoshandiswa. Shandura).
Compressive creep of refractory products inotsanangurwa se: isothermal deformation yezvigadzirwa zvakaiswa kucompressive stress nekufamba kwenguva.
Kazhinji kudzvanywa kuri 0.2MPa, uye sampuli inodiwa kuve silinda ine buri repakati, ine dhayamita ye50mm ± 0.5mm, kureba kwe50mm ± 0.5mm, uye buri repakati rine dhayamita ye12 kusvika 13mm, coaxial nehumburumbira.
