Applications of SK36 Firebricks
The use of SK36 is primarily as a lining material in various high-temperature furnaces to extend the service life of the equipment.
Common Industries for SK36 Bricks:
- Steel Industry: Used for high-temperature furnace linings, especially in steelmaking furnaces, converters, and heating furnaces.
- Cement Industry: Used in cement rotary kiln linings and preheaters.
- Glass Industry: Used in certain areas of glass melting furnaces.
- Other Metallurgical Industries: Used in non-ferrous metal smelting furnaces.
Common Kiln Locations for SK36 Bricks:
- Furnace Bottom and Walls: Suitable for use in the medium-temperature range, subject to high mechanical wear and thermal shock.
- Tuyere and Cooling Zones: Due to their excellent wear resistance, they are often used in these areas subject to wind and high thermal stress.
- Sub-High-Temperature Zones: Generally used for medium-temperature refractory linings, with temperatures around 1400°C.
