REFRACTORY MATERIALS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18181345 titled 'REFRACTORY MATERIALS
The method described in the patent application involves forming a refractory component for a foundry system by creating a preform from a mixture containing a silicon carbide preceramic polymer and either a refractory powder or refractory aggregate. The preform is then heated to pyrolyze the silicon carbide preceramic polymer, resulting in a refractory material with an oxidation-resistant surface suitable for contacting molten metal.
- The method includes using a silicon carbide preceramic polymer in the refractory mixture.
- The preform is heated to pyrolyze the polymer and form a refractory material.
- The resulting refractory material contains either a refractory powder or refractory aggregate in a silicon carbide matrix.
- The refractory component has an oxidation-resistant surface for contacting molten metal.
Potential Applications: - Foundry systems - Metal casting processes - High-temperature industrial applications
Problems Solved: - Providing an oxidation-resistant surface for refractory components in foundry systems - Enhancing the durability and performance of refractory materials in contact with molten metal
Benefits: - Improved resistance to oxidation - Enhanced durability in high-temperature environments - Increased efficiency in foundry operations
Commercial Applications: Refractory components produced using this method can be utilized in various foundry systems, metal casting processes, and high-temperature industrial applications, improving their performance and longevity.
Questions about Refractory Component Formation: 1. How does the use of a silicon carbide preceramic polymer enhance the properties of the refractory material? 2. What are the specific advantages of having an oxidation-resistant surface in refractory components for foundry systems?
Original Abstract Submitted
A method for forming a refractory component of foundry system includes forming a preform from a refractory mixture. The refractory mixture includes a silicon carbide preceramic polymer and at least one of a refractory powder or refractory aggregate. The method further includes heating the preform to pyrolyze the silicon carbide preceramic polymer and form a refractory material defining the refractory component. The resulting refractory material includes at least one of the refractory powder or the refractory aggregate in a silicon carbide matrix. The refractory component defines an oxidation-resistant surface configured to contact molten metal.
