Abstract

Recently, the operating condition of steel casting becomes severe, ex. increasing high grade steel, special grade steel and long sequences. It requires that the sliding plate (SN PLATE) should be improved to adapt such operating condition and longer life. The typical damage of SN plate is cracks, roughed surface and erosion. The cracks and the chipped bore edge may cause abnormal erosion through air suction. The oxygen from steel or air oxidize the carbon in plate, then makes rough surface. Further the calcium element in steel cause erosion. As result, it can be cause shorter life and unstable operation. In this report, we report the results of controlling of cracks, oxidation, erosion resistance, and good trial results on actual operation.
