Ko kupfeka resistance kwe zvidhinha zvinopesana zvine chekuita nazvo?

Refractory brick chinhu chakajairika refractory material. Isu tinofanirwa kuyedza ese maficha echigadzirwa panguva yekugadzira. Sezvo ichi chigadzirwa chinonyanya kushandiswa pakuvaka einjiniya madziro, izvo zvinodikanwa zvekupfeka kwayo kupikisa zvine zvakakwirira. Kana iwe uchida kunatsiridza kupfeka kwayo kuramba, iwe unofanirwa kutanga wabvisa izvo zvinokanganisa chigadzirwa chekupfeka kuramba. Ipapo mubvunzo ndewokuti, kupikisa kupfeka kwezvidhinha zvinoramba kune chokuita nazvo?

Kupokana kweabrasion yezvidhinha zvinoramba kunoenderana nekuumbwa kwayo uye chimiro. Kana chigadzirwa chacho chichiumbwa nedense polycrystals inoumbwa nekristaro imwe chete, kupikisa kwayo abrasion kunonyanya kuenderana nekuoma kwemaminerari makristasi anoumba zvinhu. Kuoma kwepamusoro, kukwirira kupfeka kusagadzikana kwezvinhu. Kana iyo mineral crystals isiri-isotropic, zviyo zvekristaro zvakanaka uye kushomeka kwekupfeka kwezvinhu kwakakwira. Kana zvinhu zvacho zvichiumbwa nezvikamu zvakawanda, kuramba kwayo kupfeka kwakanangana nehukuru hukuru kana porosity yezvinhu, uye zvakare ine chekuita nekusimba kwekubatanidza pakati pezvikamu.

Naizvozvo, kune imwe mhando yezvidhinha pane tembiricha yekamuri, yayo abrasion kuramba inoenderana nesimba rayo rekumanikidza. Kana mugadziri akafunga zvinhu zviri pamusoro apa paanenge achipisa zvidhinha zvinoramba, zvigadzirwa zvinogadzirwa zvine nani abrasion resistance. Mukuwedzera, kupikisa kupfeka kwechigadzirwa kune chokuita nekushisa panguva yekushandiswa. Zvimwe zvigadzirwa, senge yakakwira alumina zvidhinha, zvinowanzoonekwa kunge zviri patembiricha (senge mukati meiyo elastic renji pazasi 700-900 ℃). Iyo yakakwirira tembiricha, kuderera kwekushomeka kwekupfeka. Zvinogona kutariswa kuti kana kutonhora kuchiwedzera, kushomeka kwekupfeka kunoderera sezvo elastic modulus yezvidhinha inowedzera.

Chokutanga pane zvose, vanhu vanogonawo kuziva makemikari echinyorwa ichi. Nekuti refractory zvidhina mafekitori achiri mukurumbira zvakanyanya muhupenyu hwevanhu. Uye isu tose tinoziva kuti zvikamu zvayo zvikuru zvinotarisa hutano uye maitiro e refractory. Kazhinji kutaura, iwo magadzirirwo ezvigadzirwa zve refractory zvinobva kune akawanda refractory zvinhu. Naizvozvo, tiri kutanga kushandisa izvi mbishi zvinhu zvakanyanya uye zvakanyanya muhupenyu hwedu.

Chechipiri, isu tinoziva zvakare kuti ine yakakosha hunhu senge bulk density. Nekuda kwekuti zvidhinha zvekuramba zvakadaro zvinoda kushingirira tembiricha yakanyanya, vanhu vanodawo kuti vashande zvakajairwa pakupisa kwakanyanya. Nokudaro, huremu hwehuwandu hwehuwandu hune huwandu hwepamusoro, izvo zvinoreva kuti kusungirirwa kwechitinha chekuramba kwakanaka, uye simba rinounza rinogona kunge rakakwirira.

Gare gare, zvidhinha zvinoramba zvakare zvine zvakakwirira zvinodiwa kune iyo porosity. Asi mazuvano, vanhu vanofanirwa kuita zvinodiwa chaizvo mukugadzirwa kwemaindasitiri, asi semugadziri, vanonyatso kudzora mapores anooneka uye vane mhando yepamusoro. Kune rumwe rutivi, kupikisa kwekushisa kwechinyorwa ichi kwakanaka kwazvo, uye kukwanisa kwayo kupikisa kushanduka kamwe kamwe kwekushisa pasina kuparadzwa.

Inogona kuunza mabhenefiti akawandisa kuvanhu. Pane zvakawanda zvezvinhu zvitsva zvemakemikari muhupenyu hwevanhu, uye izvi ndezvekuita kuti hupenyu hwevanhu huve nani. Refractory material Refractory brick chinhu chakakosha mukugadzirwa kwemaindasitiri. Refractory material chinhu chakanyatsogadzikana chemakemikari.
