Zvakanakira magnesia kabhoni zvidhinha ndezvi:kupikisa kukukurwa kwe slag uye yakanaka thermal shock resistance. Munguva yakapfuura, kushata kweMgO-Cr2O3 zvidhinha uye zvidhinha zve dolomite ndezvekuti vaitora zvikamu zve slag, zvichikonzera kuparara kwemaitiro, zvichikonzera kukuvadzwa nguva isati yakwana. Nekuwedzera graphite, magnesia kabhoni zvidhinha zvakabvisa kukanganisa uku. Chimiro chayo ndechekuti slag inongopinda mukati mebasa rekushanda, saka iyo reaction layer Yakavharirwa kune yekushanda nzvimbo, chimiro chine zvishoma peeling uye hupenyu hurefu hwebasa.
Ikozvino, mukuwedzera kune yechinyakare asphalt uye resin-bonded magnesia kabhoni zvidhinha (kusanganisira akapiswa mafuta-akaiswa magnesia zvidhinha),magnesia kabhoni zvidhinha zvinotengeswa pamusika zvinosanganisira:
(1) Magnesia carbon brick yakagadzirwa ne magnesia ine 96% ~ 97% MgO uye graphite 94% ~ 95% C;
(2) Magnesia kabhoni zvidhinha zvakagadzirwa nemagnesia ine 97.5% ~ 98.5% MgO uye graphite 96% ~ 97% C;
(3) Magnesia kabhoni zvidhinha zvakagadzirwa nemagnesia ine 98.5% ~ 99% MgO uye 98% ~C graphite.
Zvinoenderana nekabhoni yemukati, magnesia kabhoni zvidhinha zvakakamurwa kuita:
(I) Kupisa mafuta-akaiswa magnesia zvidhinha (carbon content isingasviki 2%);
(2) Carbon bonded magnesia zvidhinha (carbon content isingasviki 7%);
(3) Synthetic resin bonded magnesia kabhoni zvidhinha (kabhoni yemukati i8% ~ 20%, kusvika 25% mune mashoma mashoma). Antioxidants inowanzowedzerwa kune asphalt / resin bonded magnesia kabhoni zvidhinha (carbon content i8% kusvika 20%).
Magnesia kabhoni zvidhinha zvinogadzirwa nekubatanidza yakakwirira-kuchena MgO jecha ne scaly graphite, kabhoni dema, etc. Iyo yekugadzira nzira inosanganisira zvinotevera maitiro: raw material kupwanya, kuongorora, kugadzika, kusanganisa maererano neyakagadzirwa fomula dhizaini uye chigadzirwa kuseta kuita, zvinoenderana ne musanganiswa Tembiricha yerudzi rweagent inosimudzwa kusvika pa100 ~ 200 ℃, uye inokandwa pamwe chete nebhainda kuti iwane inonzi MgO-C dhaka (green body musanganiswa). Iyo MgO-C mud material inoshandisa synthetic resin (kunyanya phenolic resin) inoumbwa munzvimbo inotonhora; iyo MgO-C mud material yakasanganiswa neasphalt (inopisa kune imwe mamiriro emvura) inoumbwa munzvimbo inopisa (inenge 100 ° C) ichiumba. Zvinoenderana nehukuru hwebatch uye kuita zvinodiwa zveMgO-C zvigadzirwa, vacuum vibration midziyo, compression yekuumba midziyo, extruder, isostatic presses, inopisa muchina, zvekudziisa, uye ramming midziyo inogona kushandiswa kugadzirisa MgO-C madhaka zvinhu. kune chimiro chakanaka. Muviri wakaumbwa weMgO-C unoiswa muchoto pa700 ~ 1200 ° C kuitira kupisa kwekupisa kushandura iyo inosunga mugabhoni (iyi nzira inonzi carbonization). Kuti uwedzere kuwanda kwe magnesia kabhoni zvidhinha uye kusimbisa kusungirirwa, mafirita akafanana nemabhaidhi anogona kushandiswawo kupfekedza zvidhinha.
Mazuva ano, synthetic resin (kunyanya phenolic resin) inonyanya kushandiswa sechinhu chinosunga magnesia kabhoni zvidhinha.Iko kushandiswa kwesynthetic resin bonded magnesia kabhoni zvidhinha kune zvinotevera zvakakosha zvakanakira:
(1) Mamiriro ezvakatipoteredza anobvumira kugadziriswa nekugadzirwa kwezvinhu izvi;
(2) Maitiro ekugadzira zvigadzirwa pasi pemamiriro echando ekusanganisa anochengetedza simba;
(3) Chigadzirwa chacho chinogona kugadziriswa pasi pemamiriro asina kuporesa;
(4) Kuenzaniswa netar asphalt binder, hapana chikamu chepurasitiki;
(5) Kuwedzera kabhoni yemukati (yakawanda graphite kana bituminous marasha) inogona kuvandudza kupfeka kusagadzikana uye kuramba slag.
