| Abstract: | The nodulizer containing small amounts of rare earth and silicon is applied to experiment in order to solve the problems of slag clinging to the inside wall of ductile lron pipe and low percentage of elongation and flattening up to standard.The result indicates that the amount of slag is reduced and the percentage of elongation and flattening up to standard are improved by 25.3 % and 19.4% respectively. |
| Keywords: | centrifugal ductile iron pipe low Re and Si nodulizer quality |
