Henan Xinhongji Refractory Material Co. Ltd.’s Post

🔥 Experience Superior Performance with Xinhongji Refractory's Corundum Castable! 🔥 1, Chemical Composition: a) Primary Component:  The primary component is aluminum oxide (Al2O3), which ranges typically from 95% to 99.9% purity in high-quality alumina materials. High-purity corundum (Al2O3) for exceptional thermal and chemical resistance. Other Component: b) Silicon Dioxide (SiO2): Presence: Silicon dioxide is a common impurity in alumina. Silicon dioxide can impact the mechanical and thermal properties of alumina-based materials. c) Iron Oxide (Fe2O3): Presence: Iron oxide can be present as an impurity. Iron oxide can affect the color and electrical properties of alumina, especially in lower purity grades. d) Binders and Additives: Engineered to optimize strength, adhesion, and thermal properties. 2, Characteristics: a) High Refractoriness: Withstands temperatures exceeding 1800°C, ideal for extreme heat environments. Melting point of pure corundum (Al2O3) is approximately 2040°C. b) Excellent Corrosion Resistance: Resists chemical attacks from acids, alkalis, and slags. Withstands harsh chemical environments without significant degradation. c) Low Thermal Conductivity: Typical Range: 1.5 - 2.5 W/(m·K) at room temperature. Ensures efficient heat insulation and energy savings. d) High Mechanical Strength: Typically ranges from 50 to 150 MPa. Flexural Strength is Around 10-30 MPa. Provides durability and resistance to mechanical stresses. 3, Production Procedure: a) Material Selection: High-grade corundum and tailored additives are chosen for specific properties. b) Mixing and Blending: Precise blending to achieve optimal particle distribution and binder ratios. c) Forming and Curing: Shaped into molds and cured to establish desired strength and integrity. d) Firing and Curing: High-temperature firing to develop final properties and ensure performance. 4, Applications: a) Steel Industry: Ideal for ladles, tundishes, and other high-temperature steelmaking applications. b) Non-Ferrous Metals: Used in smelting processes for copper, aluminum, and other non-ferrous metals. c) Petrochemical Sector: Suitable for catalyst beds, reformers, and reactors in harsh chemical environments. d) Incinerators and Kilns: Essential for lining waste incinerators, rotary kilns, and combustion chambers. e) Glass Manufacturing: Used in glass tank furnaces and regenerators for consistent performance.
