Kuomesa, kudziyisa uye kuchengetedza simende kiln castables

Iyo yakaomeswa kana yakaomeswa inokandwa ichine yakasara yemuviri uye yemakemikari mvura, uye yobva yadziiswa kusvika 300 ℃ kuti ipfuure uye ipere mvura, uye mvura yese inobuda. Nekuti iyo inokandwa ine dense chimiro, mwero wekupisa unofanirwa kunonoka kudzivirira kukurumidza kukwira kwekushisa. Kushungurudzika kunokonzerwa nekukurumidza evaporation kwepamusoro uye unyoro kunokonzera kukanganisa kwekukanda.

Iyo yekuomesa uye yekudziya sisitimu yehuni system dzimwe nguva haigone kusangana nekuomeswa kweiyo preheater uye calciner (grate inotonhorera, kiln hood uye yepamusoro yemhepo duct inosangana nekuomeswa nekudziya system yehuni system, uye haina kunyorwa zvakasiyana), saka, Iyo yekubikira yekudziya system yehuni system inotaurwa pazasi inofanira kusanganiswa nezvinodiwa zvechikamu ichi. Kana tembiricha yehuni system inosvika 600 ° C (zvichienderana nekupisa kwegasi rekubuda pamuswe wemoto), iyo yekutanga preheater haina kusangana nezvinodiwa zvekuomesa, uye nguva yekuchengetedza kupisa kwehuni system pa600 ° C inofanira. kuwedzerwa.

Nguva yekuporesa yeboka rekupedzisira refractory castables haisi pasi pe 24h pakupisa kweanenge 25 ° C (yepasi pesimende castables, nguva yekurapa inofanira kuwedzerwa kusvika 48h sezvakakodzera). Mushure mekunge iyo castable yawana rimwe simba, bvisa fomu uye rutsigiro. Kubika kunogona kuitwa mushure me24h kuoma. Kana tembiricha yekurapa yakaderera zvakanyanya, nguva yekurapa inoda kuwedzerwa.

Tora tembiricha yemhepo yekuburitsa gasi pamuswe wechoto seyakajairwa, uye shandisa kudziya kwe15 ° C / h kusvika yasvika 200 ° C, uye chengeta kwemaawa gumi nemaviri.

Simudza tembiricha kusvika 400 ° C pamwero wekudziya we25 ° C/h, uye chengetedza tembiricha isingasviki 6h.

Simudza tembiricha kusvika 600 ° C uye chengetedza tembiricha isingasviki 6h. Mamiriro maviri anotevera ndiwo anodiwa uye akakwana mamiriro ekubikwa kwecalciner uye preheater system:

Kana tembiricha yeiyo refractory inokandwa mugomba rekudururira remudutu preheater padyo nesilicon chivharo chasvika 100 ℃, nguva yekuomesa haifanire kunge iri pasi pe24h.

Pamusuwo wegomba rekutanga-level cyclone preheater, chidimbu chegirazi chakachena chakashandiswa kubata gasi reflue, uye hapana kudonha hunyoro pagirazi kwakaonekwa. Nguva yekuchengetedza kupisa yaive maawa matanhatu.
