Measurement of Thermal Conductivity of Magnesia Brick with Straight Brick Specimens by Hot Wire Method
As a result of a revision of the JIS system, the application of the hot wire method for determining thermal conductivity has been expanded from heat-insulating bricks to refractories with higher heat conductivity. In this regard, focusing on magnesia bricks, which are used in the safety lining of converters and a wide variety of other applications, the authors studied the possibility of applyin...

These seventeen hāts have been classified into five categories based on their syllabic meter and the number of the song: 1) ahunavaiti, 2) ushtavaiti, 3)spanta.mainyu, ...
متن کاملIMPROVING HYDRATION RESISTANCE OF MAGNESIA-DOLOMA REFRACTORIES BYIRON OXIDE ADDITION
Abstract: There have been lots of studies to control the poor hydration resistance of dolomite refractories one of themost effective solutions has been the addition of magnesia to doloma. Using a co-clinker of magnesia-doloma as astarting material would provide more homogeneity in the properties of the product and has been published recently.On the other hand, addition of iron oxide to doloma h...
متن کاملINFLUENCE OF MAGNESIA ADDITION ON HYDRATION OF IRANIAN DOLOMITE
ABSTRACT Dolomite refractories have a good production potential in Iran due to the existence of high-quality dolomite ore in many regions of the country, particularly in Isfahan and Hamedan. The basic problem associated with the production and use of this type of refractories is inherent tendency to hydration of calcined dolomite. One of the methods to overcome this problem is to increase the...
