Abstract (en)
An improved crucible liner maintains a relatively thick reaction layer (34) on the inside of the crucible during pouring of a molten nickel chrome alloy. By maintaining a thick reaction layer inside the liner, the transfer of impurities from the crucible to a cast article is minimized. The liner is formed by impregnating the inside of the refractory liner (32) with an alkaline earth oxide such as calcium or magnesium. When a nickel chrome alloy is melted in the crucible liner, the alloy reacts with the liner and the alkaline earth oxide. The reaction products are deposited on the surface of the liner (11) and adhere to the surface of the liner during pouring.
