Basa guru rekuvhara zvidhinha kuchengetedza kupisa uye kuderedza kupisa kurasikirwa. Zvidhinha zvekudzivirira kazhinji hazvibatanidze nemurazvo, uye chidhinha chemoto chinowanzo sangana nemurazvo. Zvidhinha zvemoto zvinonyanya kushandiswa kutsungirira murazvo wekugochwa. Inowanzo kupatsanurwa kuita mhando mbiri, dzinoti indefinite Unshaped refractory material uye shaped refractory material.
Unshaped Refractory Material
Iyo castables refractory material yakasanganiswa powdery particle inoumbwa nemhando dzakasiyana dzeaggregates kana aggregates uye imwe kana anopfuura anosunga. Iko kushandiswa kunofanirwa kusanganiswa neimwechete kana kupfuura zvinwiwa, zvine fluidity yakasimba.
Yakaumbwa Refractory Material
Mumamiriro ezvinhu akajairwa, chimiro chezvidhinha chinoramba chine saizi yakajairwa, inogonawo kugadzirwa zvinoenderana nezvinodiwa nevatengi.
Musiyano Mukuru Pakati peIsulation Bricks & Firebricks
1. Insulation Performance
Iko kupisa kwekushisa kwezvidhinha zvekudzivirira kunowanzo kuve 0.2-0.4 (avhareji tembiricha 350±25°C)w/mk, uye kupisa kwemafuta ezvidhinha zvemoto kuri pamusoro pe1.0 (avhareji tembiricha 350±25°C)w/mk Naizvozvo, thermal insulation. kushanda kwezvidhinha zvekudzivirira zviri nani kudarika zvidhinha zvemoto.
2. Refractoriness
Iyo refractoriness yechidhinha chinodzivirira kazhinji iri pasi pe1400 madhigirii, uye refractoriness yechidhinha chinoramba chiri pamusoro pe1400 degrees.
3. Density
Zvidhinha zvekuisa zvidhinha zvinhu zvisingaremi zvekudzivirira, kuwanda kwezvidhinha zvekuvharisa kazhinji 0.8-1.0g/cm3 uye kuwanda kwezvidhinha zvinoramba kuri pamusoro pe2.0g/cm3.
Mhedziso
Muchidimbu, zvidhinha zvinoramba zvine simba rakawanda remagetsi, hupenyu hurefu hwebasa, kugadzikana kwekemikari yakanaka, hapana kemikari inopindirana nezvinhu uye yakanaka yekudzivirira kupisa kwekushisa, uye tembiricha inodzivirira kupisa inogona kusvika 1900 ° C. Refractory zvidhinha inonyanya kukodzera kushandiswa mune yakakwirira-yakaderera tembiricha inoshandura shanduko, shanduko, hydrogenation converters, desulfurization matangi, uye methanation furnaces yemakemikari fetiraiza zvidyarwa kuita basa mukuparadzira gasi zvinwiwa, kutsigira, kuvhara, nekudzivirira zvinokonzeresa. Moto refractory zvidhinha zvinogonawo kushandiswa muzvitofu zvinopisa uye midziyo yekushandura yekudziya muindasitiri yesimbi.
Zvidhinha zvemoto zvine zvakanakira kusimba kwepamusoro, kusimba kwepamusoro, kusapfeka, kumira zvakanaka kwecorrosion, kuderera kwekuwedzera kwemafuta ekuwedzera, kugona kukuru kwekukuya, ruzha rwakaderera, hupenyu hurefu hwesevhisi, uye zvinhu zvisina kusvibisa. Iyo yakanaka yekukuya svikiro inokodzera michina yakasiyana-siyana yekukuya.
Refractory zvidhinha uye zvidhinha zvekudzivirira zvakasiyana zvakanyanya, kushandiswa kwavo kwezvakatipoteredza, chiyero uye basa hazvina kufanana. Zvinhu zvakasiyana zvichashandiswa munzvimbo dzakasiyana. Kana tichitenga zvinhu, isu tinofanirwa kusarudza kuti ndeupi rudzi rwezvinhu zvinoramba zvinokodzera isu pachedu kushandisa zvinoenderana nemamiriro edu chaiwo.
