配加锈化球烧结试验研究

Experiment and Study Adding Rust Balls into Sintering Materials

对配加锈化球烧结进行了基准试验和不同配比的系列试验。试验证明 ,混匀料中配加 10 %的锈化球 ,试验的判定指标可达到最佳值 ;锈化球可以取代粗粉保证料层具有良好的透气性 ;实际生产时 ,建议锈化球的粒度须小于 8mm ,其中 1～ 6mm占 80

The datum sintering experiment and series sintering experiment mixing different rate of rust ball have been taken. The experiments have improved that adding 10% of rust into mixing materials can make the determinant indexes reach the best; the rust balls can take the place of the thick powders to keep better air permeability. In practice production, it is suggested that the grain size of rust balls should be small than 8mm. It is the best to keep the size of 80% of balls between 1～6mm.
