Product detail
High Alumina Bricks for Ladle
Product Introduction
High alumina bricks for ladles are crafted from top-grade alumina materials. Through precise processing and high-temperature firing, they possess a dense structure. The alumina content is relatively high,which significantly enhances their refractoriness and load-bearing capacity at high temperatures.
Application
These bricks are predominantly used in the critical areas of steel ladle linings, such as the slag line and the bottom part where the molten steel has the most significant impact. They can effectively resist the scouring and chemical corrosion of high-temperature molten steel and slag, maintaining the stability and integrity of the ladle structure during the steelmaking and pouring procedures.
Advantages
– Exceptional High Temperature Resistance: Withstand extremely high temperatures, remaining stable and maintaining their mechanical properties even in the harsh environment of molten steel.
– Strong Erosion Resistance: Exhibit outstanding resistance to the erosion caused by the flow and chemical reaction of molten steel and slag, thereby extending the service life of the ladle lining and reducing the frequency of repairs and replacements.
