Tabular & lwm yam Aggregates
Aggregates yog cov caj qaum ntawm cov txheej txheem refractory thiab muab qhov ruaj khov rau cov khoom siv refractory.Cov coarser fractions ntxiv thermal shock thiab corrosion kuj thiab aggregate fines optimize particle loj tis thiab ua rau kom cov refractoriness ntawm cov khoom.
Qhov zoo ib yam ntawm Tabular alumina yog tshwm sim los ntawm kev tswj kom zoo sinter txheej txheem nrog firing kub saum 1800 ° C. Kev siv cov kub kub furnaces nrog lub xeev-of-the-art technology tso cai densification ntawm xaiv raw cov ntaub ntawv yam tsis muaj sintering pab uas yuav. tsis zoo cuam tshuam qhov kub siab ntawm cov refractories.
Raws li qhov tshwm sim ntawm cov txheej txheem sinter, cov aggregates qhia tib yam mineralogical thiab tshuaj muaj pes tsawg leeg rau tag nrho cov feem.Contrary to fused products where impurities accumulate in the fines, the use sintered aggregates in refractory formulation guarantees ruaj khov thiab txhim khu kev qha tus cwj pwm.
Junsheng muaj ntau qhov sib txawv ntawm cov khoom sib xyaw los ntawm cov feem ntxhib heev rau qhov loj me me ntawm <45 μm thiab <20 μm.Crushing thiab milling yog ua raws li cov kauj ruam de-ironing hnyav uas ua rau cov hlau tsis muaj hlau tsis tshua muaj nyob hauv ntau qhov feem.

Daim ntawv thov ntawm Tabular Alumina
Tabular Alumina yog cov khoom ntawm kev xaiv nyob rau hauv unshaped high efficiency refractories siv nyob rau hauv ntau yam industries xws li steel, foundry, cement, iav, prtrochemical, ceramic, thiab pov tseg incineration.Lwm daim ntawv thov uas tsis yog-refractory muaj xws li nws siv hauv cov rooj tog zaum thiab rau hlau pom.
