抄録

  Here is reported the fundamental research on the production of the acid-resisting pipe by the centrifugal casting process, which consists of grey cast iron in the outside and high silicon cast iron in the inside in order to strengthen the brittleness of high silicon cast iron, to improve machinability of the outside, and to save expensive material.</br>  The results obtained are as follows :</br> 1. The boundary between high silicon and common cast iron had better to be as narrow as possible and to be clearly separated into two layers because corrosion-resisting property is injured by the movement of much amount of carbon into the high silicon part.</br> 2. The more beutiful casting surface of the inside high silicon cast iron was obtained by the higher casting temperature.</br> 3. If the temperature of grey cast iron is too low or its oxidation is severe when high silicon cast iron is cast, shrinkage cavities occur in the boundary.</br> 4. In this experiment, the dual metal of the pipe 150 mm in diameter, 40 mm in width and 10∼20 mm in thickness was produced at the temperature of grey iron 1200°C, when high silicon cast iron was cast at 1300°C. It obtained the bending 6.5 mm with the load 4700 kg. (M. I.)
