摘要
具有表面吸附作用的稀土能显著改善高镍铬奥氏体钢的抗氧化性、耐磨性、韧性和长期时效稳定性等高温性能。利用稀土该特性研制水泥窑用ZG189RE耐热耐磨钢铸件,能延长使用寿命,较大地减少钢中镍铬含量,降低生产成本。这已为生产所证实,用户反应良好。
A rare-earth element that has surface absorption behavior can markedly improve the high-temperature behavior of steel: high-temperature oxidation resistance, high-temperature wearing feature, high-temperature toughness and high-temperature prolonged aging stability of high nickel-chrome austenite steel for the cement kiln. The development of the ZG189RE heat-abrasion resistance steel east used in the cement kiln by using the characteristic property of a rare-earth element can increase its life-time, reduce the content Nickel-chrome element in steel greatly and decrease the cost of Production. This is confirmed by production.
