高纯稀土在履带用钢工业生产上的应用
Application of Ultra-pure Rare Earth on the Manufacture of Caterpillar Track Steel
摘要
Abstract
The industrial production and preparation technology for typical caterpillar track steel 35MnBH with rare earth addition is developed through converter smelting,LF furnace refining,VD furnace vacuum degassing,and continuous casting.The effects of the amount and timing of the addition of ultra-pure rare earth metal on process smoothness and product quality were investigated.The results indicate that adding 0.01%～0.02%of ultra-pure rare earth Ce before the VD process enabled the continuous casting of 35MnBH rare earth steel for two heats with smooth production.The residual rare earth content in the cast billets was approximately 0.001%,significantly improving the metallurgical quality of the billets.While the mechanical properties of the rolled materials showed little change,the hardness and wear resistance of the chain track products were enhanced obviously.关键词
