High-simba kupfeka-resistant epurasitiki refractoryimhando yezvinhu zvisina kuumbika zvinoramba zvakagadzirirwa kuti zvishandiswe mukupisa kwepamusoro-soro, kukwenya zvakanyanya, uye kunyura kwakasimba. Inoratidzira plastiki yakasimba, kuvakwa kuri nyore, kusimba kwepamusoro, uye yakanakisa kupfeka kuramba, uye inoshandiswa zvakanyanya senge remukati jira remakiyi epamusoro-tembiricha michina mumaindasitiri akadai sesimba, simbi, simende, uye kemikari engineering.

Basic raw materials emhando yepamusoro-simba uye isingapfeki zvinhu zvepurasitiki:

Aggregates uye powders: High-alumina bauxite, corundum, silicon carbide, chromite jecha, uye zvimwe zvipfeko zvinodzivirira zvipfeko zvinosarudzwa kuti zvigadzire skeleton yezvinhu, kutarisa kupfeka kuramba uye kupisa kwakanyanya.
Binders: Kune ma hydraulic binders (akadai sealuminate simenti) uye makemikari binders (akadai sephosphoric acid uye phosphate), iyo inogona kurapwa pakupisa kwekamuri pasina kupisa-kupisa sintering.
Admixtures: Wedzera zvinoderedza mvura, plasticizers, uye anti-cracking agents kuti uwedzere kushanda uye kutsemuka kuramba panguva yekuvaka; sanganisira simbi fibers uye ceramic fibers kuti uvandudze kukanganiswa kwemaitiro uye kupisa kwekushomeka kuramba.

Hunoshanda hunhu hwepamusoro-simba kupfeka-inodzivirira epurasitiki zvinhu:

"Plastiki refractory zvinhu":inoreva zvinhu zvinoramba zvichiratidza kunaka kwepurasitiki pane tembiricha yekamuri (yakafanana neplasticine), uye inogona kuvakwa kuburikidza nenzira dzakaita se ramming uye kupfeka, pasina kuda vibration yekuumba.
"High simba uye kupfeka kuramba": Nekuwedzera maaggregates akaoma akadai se corundum, silicon carbide (SiC), mullite, uye high-alumina clinker, nekuzvibatanidza ne phosphate, calcium aluminate simenti, kana organic binders, inowana simba rakanyanya kumanikidzika pakupisa kwekamuri / kupisa kwepamusoro (≥60 MPa mushure mekuoma pa 110 ≥8 mushure mekuoma, MPa 110 ≄8 1350 ℃) uye kupfeka kwakanaka kuramba (kupfeka kurasikirwa ≤5 cm³, zviri nani pane zvakajairwa zvinokandwa)

Musiyano mukuru pakati pepurasitiki-yesimba-inodzivirira kupfeka purasitiki nepurasitiki yakajairwa iri mu:

Pfekai-resistant reinforcement chikamu:Yepamusoro-simba rinopfeka-rinodzivirira epurasitiki zvinhu zvinowedzerwa neakanyanya-zvakaoma-kupfeka-anodzivirira aggregates senge silicon carbide uye corundum, kana simbi inomira-inodzivirira fibers, zvichikonzera kupfekedzwa kwekupokana iyo yakakwira 2-3 yakapetwa kupfuura yeyakajairika mapurasitiki zvinhu.
Zviratidzo zvesimba:Iyo inoratidza yakakwira yekumanikidza simba pamakamuri ese uye tembiricha yakakwira, ichiita kuti ive yakakodzera kune yakaoma mamiriro ekushanda ane simba rakawanda uye mitoro inorema. Kusiyana neizvi, zvakajairwa zvepurasitiki zvimisikidzo zvakanyanya kufanira kupisa kupisa kana yekubatsira lining application ine yakaderera kupfeka uye kubvaruka.
