４μ）１６を供給し、下記の条件下で試験した。In continuous casting, molten metal is continuously injected into a mold and pulled out from below. At this time, the mold is water-cooled, causing slag to be caught in the sliding contact surface between the mold surface and the solidified shell. In addition to filtering, the mold is subjected to long vertical movements with long cycles to prevent the solidified shell from adhering to the mold. In order to reproduce such a state, a rectangular copper piece 3a with a U-shaped water cooling hole 14 formed inside and a through hole I5 formed in the center was used as the test piece 3, as shown in FIG. Protective EQh, 4 made of wear-resistant material shown in Table 2 on one side of the surface.

かる。From the results in Table 2, it can be seen that the three-layer stack of Ni, N1-P and Cr has poorer high-temperature wear resistance than the one with a sprayed coating made of a self-fluxing alloy. This result is in good agreement with the fact that multi-coated items require repair after several charges, and items sprayed with self-fluxing alloys are said to have several times better wear resistance than the former. This shows that the high-temperature abrasion resistance of various materials can be determined by using the high-temperature abrasion tester according to the present invention.
