Product Description of High Temperature Performance Blast Furnace Waist Mullite Refractory Brick Fot Hot Sale
The corundum bricks produced by Rongsheng feature low impurity content, high strength, and excellent stability at high temperatures. The corundum-mullite bricks are particularly well-received by users. In recent years, Rongsheng upgraded its firing process by replacing traditional tunnel kilns with connected shuttle kilns, allowing for higher firing temperatures. This enhancement has effectively ensured that all performance indicators of Rongsheng's corundum-mullite bricks are met, delivering outstanding usage results.
Corundum bricks are refractory products with an alumina content greater than 90%, with corundum as the main crystal phase. They exhibit very high compressive strength at room temperature (generally above 80 MPa), a high initial softening temperature under load (above 1700°C), and excellent chemical stability, providing strong resistance to acidic or basic slags, metals, and molten glass.
For blast furnace applications in the current steel smelting industry, Rongsheng's corundum-mullite bricks offer the following advantages:
Excellent high-temperature performance, with good thermal stability at prolonged high temperatures.
High strength at both room and high temperatures, along with good wear resistance.
High density, good thermal conductivity, low apparent porosity, and minimal shrinkage at high temperatures.
Resistance to intense erosion and corrosion by molten iron, slag, blast furnace gas, and dust under high temperature and high pressure.
Accurate brick dimensions, ensuring that the brick joints meet specified requirements.
As a result, many customers choose Rongsheng's mullite refractory bricks for blast furnace belly, bottom, and shaft applications.
