Description
Applicationem
Brown Fused Alumina lenta est, abrasiva acuta, quae valde apta est ad stridorem metallorum magnae distrahendi vires.Eius possessiones scelerisque praestantem materiam usui praestant in fabricando productorum refractariis.Haec materia etiam in aliis medicamentis adhibetur, sicut uredine et induratione superficiei.

Gradus lateris/vitrificati BFA : Producitur utens speciali gradu Bauxite in parametris fusione sobrie.Hic gradus aptus est ad Bricks/Vitrificata producta praecavens Cracks/Fissurae, Foramina et maculae nigrae in fine producti.
Processus productionis
Brown Fused Alumina gignitur ex excoquunti Bauxite Calcined in fornace electrico in temperaturis plus quam 2000°C.Processus solidificationis tarda sequitur fusionem, ut crystallus obtusus cedat.Auxilia liquefactionis ad tollendum residua sulphuris et carbonis, moderatio stricta super Titania gradus in fusione processus optimam duritiem granorum efficit.
Tum crudus refrigeratus ulterius tusus, magneticae immunditiae purgatur in magno intensione separatorum magneticarum, et in fractiones angustas magnitudine indicatur ad finem usui accommodatum.Lineae dedicatae producta pro diversis applicationibus efficiunt.
