1. Development of Mass Production Technology for High Efficiency Nitride Nozzle
The project is planned to develop a commercial scale reactor for the production of aluminum nitride refractory material which can be used as a raw powder for continuous casting refractory parts. Comparing to currently available alumina-C based products, aluminum nitride-C would achieve the extension of the part life by 150%, compressive strength over 250 $kg/cm^2$, and thermal shock resistance over $T=350^{\circ}C$. The followings are the work scope and content:
$\circ$ Production technology of aluminum nitride material by self-propagating high temperature synthesis method.
- Designing and construction of commercial scale reactor
- Production of nitride materials and reactor optimization
- Development of powder production system flow
$\circ$ Evaluation of aluminum nitride-C based refractory bodies
- Mixture preparation and forming
- Property evaluation of carbonized products
2. Development of Mass Production Technology of High Efficiency Composite Materials with Excellent Thermal and Corrosion Resistance
The final object of the second stage research is to develop the technology to commercializing on high efficient, high performance carbon fiber-SiC composites. In the case of radiant tubes, which were having the characterizations of high efficient and high performance, were fabricated this dimension (50mmOD${\times}$45mmID${\times}$1500mmL), and the fabricated dimension of burner nozzles were 5mmOD${\times}$65mmID${\times}$500mmL. To produce the tubes and the nozzles, the prototypes were fabricated, and the process was optimized for reproduction through the automation of shape processing. In addition, the developed prototype samples were examined the thermal, mechanical properties in working field. Also to accomplish the long term performance test and optimize the technology for commercializing, the processing technologies, which were heat treatment furnaces and various shaped radiant tubes, were achieved. Then the developed products through the long term test in work field were tested and complemented.
3. Development of Mass Production Technology of Graphite Contained Refractory with Low Thermal Conductivity
The target of this study is the maintenance excellent properties of conventional carbon containing refractories of and the reducing thermal conductivity above 50%. In the first year, properties improving technique of low thermal conductive refractories was developed by the examination of matrix control, corrosion resistance improvement, and supplement of thermal shock resistance. In the second year, commercial-scale technique of low thermal conductive refractories was developed by the investigation of mass-production process and their field test.
