More Information
Summary:The invention provides an inner tube resistant to high temperature, oxidation and corrosion, a copper mold containing the inner tube and and a preparation method. The inner tube is prepared from, by mass, 95-97% of iron, 0.06-0.08% of aluminum, 0.9-1.3% of silicon, 0.01-0.02% of vanadium, 2-3% of chromium, 0.1-0.15% of manganese, 0.03-0.04% of nickel, 0.002-0.003% of titanium, 0.01-0.015% of cobalt and the balance inevitable impurities. The inner tube has high high-temperature resistance, oxidation resistance and corrosion resistance, the service life of the inner tube can be prolonged by 8 months or above, meanwhile, after the inner tube is used for 8 months, the inner tube can be repaired or replaced according to the situation, demolding can be easily conducted after a crude copper block is cast, after the inner tube is used in cooperation with a shell, only the inner tube needs to be repaired or replaced, the shell is still used repeatedly, and thus, the cost of the copper mold is greatly reduced until the
