High Alumina Carbon Refractories
arbon Based Refractories
Carbon based refractories behave differently than the typical ceramic refractories, primarily because carbon based refractories are conductive rather than insulating. All carbon based refractory lining systems perform as a ‘conductive cooling system’ as opposed to a classic definition of a refractory lining that is typically an ‘insulating system’. Consequently, proper cooling must always be utilized with any carbon based refractory lining system to assist in maintaining refractory temperatures that are below the critical chemical attack temperature for mechanisms such as oxidation, alkali, CO degradation, or dissolution of the carbon by liquid metal. The words ‘carbon’ and ‘graphite’ are often used inter-changeably, but the two are not synonymous. Additionally, the words ‘semi-graphite’ and ‘semi-graphitic’ are also similarly misused.
Chrome Megnesite Bricks
|For Use in||Side Walls|
|Size (Inches)||9 In. X 4 In. X 3 In.,9 In. X 3 In. X 2 In.,12 In. X 4 In. X 2 In.|
Clay Bricks: Clay bricks are mostly used to decorate the outer a part of the hearths, ovens and furnaces because it has restricted capability to face up to high temperatures. Although it''s baked in high temperatures, it''s vulnerable to cracks. Thus it''s rarely wont to build the inside components of ovens. Clay bricks need constant replacements compared to the opposite styles of bricks. It can be found in numerous sizes and shapes. Clay bricks are quite cheap and might be bought from on-line outlets.
Insulation bricks: These normal bricks are used to build the inside surfaces of ovens and furnaces. It absorbs temperature and keeps it from escaping the surfaces. The insulation bricks are thin in weight. It’s additionally more cost-effective as compared to the high duty bricks.
Dense and heavy bricks: Another common style of fireplace brick includes the dense and heavy selection that contains oxide and aluminium oxide. These bricks are tensile and may be used for a spread of functions. It’s quite sturdy and robust. Heavy bricks are available in several sizes and shapes to build differing kinds of ovens and furnaces. It’s used for each industrial and domestic functions.
High duty bricks: This selection has the ability to face up to very high temperatures because it contains 500th of aluminium oxide. It’s the most expensive varieties of bricks used to build the interiors of furnaces. However, it will rarely be used to build ovens because it withholds heat which may burn food things.
