Development and Application of Advanced Refractory Particles for Spheroidizing
1. Introduction
Spheroidizing is a process in which metal or alloy particles are heated in a furnace to a temperature above their melting point, forming a molten core surrounded by a semi-molten high-strength material. During this process, high strength refractory particles are frequently added. The role of these particles is to protect the molten core from oxidation, reduce viscosity, form a homogeneous material, and reduce overall heating time. In general, these particles are tightly packed, so the applied particles should have a high abrasion and impact resistance.
2. Development of Advanced Refractory Particles
The development of high-strength refractory particles for spheroidizing has been driven by a need to improve production efficiency and produce higher-quality products. This has led to a number of technological advances in this field. One such advance includes the development of high-performance particles combining high purity materials with a unique fusion and processing procedure. These particles are typically composed of alumina, zirconia, and magnesia, offering superior strength and durability. Additionally, some particles have been designed with an enhanced thermal shock resistance.
3. Application of Advanced Refractory Particles
One of the primary uses of high-strength refractory particles is in stopper rod applications. Stoppers are usually made of a combination of porous and dense refractory particles, which are heated in a furnace to form a unified material. The high-strength refractory particles are crucial in achieving efficient thermal shock resistance, uniformity and uniform pore structure. In other instances, spheroidizing refractory particles can be used to reduce wear and tear on equipment, in particular with ladle shrouds, seal rings and other protected components.
4. Conclusion
In conclusion, high-strength refractory particles are a key component in the spheroidizing process. Improved refractory particles offer enhanced efficiency and product quality, and offer superior abrasion and thermal shock resistance which is ideal for stopper rod and other applications. Furthermore, these particles are typically composed of a durable and reliable blend of individual constituents, such as alumina, zirconia, and magnesia. This blend provides superior performance and reliability for a wide range of applications.
