The possibility of using crude Alborslanayat The White Alcaúlanayat in manufacturing insulating refractories

Abstract

During the search, insulating refractories manufacturing of raw materials in the form of mixtures of raw materials in the form of mixtures Iraqi of fallow Slanayat ore gradually Habibi (1-2, 0-1,> 25, 0 mm) and percentages by weight (20, 30, 50%) and White Alcaúlanayat by (20%) with the addition of water formation (9%) and spent oil (10%) to be formed templates multiple shapes and sizes and CBS $ (250 kg / cm)Dried samples and burned at a temperature (1200 m) in electric furnaces (6 hours) and Bathing Andaja (2 hours).The tests thermal resistance to thermal shock in the results has passed the limits of standard German (DIN, 51068 Part2, 1867), while results showed variables re-burning within the permissible limits (2%) and less so, either thermal conductivity of these samples produced was Atia and so The efficiency of refractories good thermal insulation.As results of the analysis showed the metal (XRD) samples produced consist mainly of Alchristopleight and Moleight well phasic Altredmaat and Elkinaat.As a result can be used buffer Khrarriet in insulation and lining engineering and agricultural facilities as well as the vitality of high importance and that can protect them from fire.
