Innovative Composite Material for Continuous Casting
A novel composite material and continuous casting method have been patented, offering significant improvements in surface quality and long-term casting capabilities. The invention, disclosed by Sumitomo Electric Industries, Ltd. and its inventors, utilizes a porous body with a filler composed of nitrides, carbides, and carbon to reduce molten metal flow into the gap between the nozzle and movable mold.
Key Takeaways:
- The composite material comprises a porous body with a filler that is internally present in at least a part of the surface portion, which comes into contact with a melt of pure magnesium or a magnesium alloy.
- The filler is composed of at least one substance selected from among nitrides, carbides, and carbon.
- The invention enables continuous casting of a cast material with excellent surface quality for a long period of time.
- The component for continuous casting is less susceptible to molten metal flow into the gap between the nozzle and movable mold.
- The patent was filed on June 3, 2011, under Application No. PCT/JP2011/062824.
- The inventors, Michimasa Miyanaga, Takeshi Uchihara, Masatada Numano, Yukihiro Oishi, and Nozomu Kawabe, are employees of Sumitomo Electric Industries, Ltd.
