In the article, it is discussed the technology for producing the bridge steel products with the yield ratio no more than 0.84 is found out with the advanced steelmaking and steel rolling equipment of Rare Earth Steel Plate Plant of Baotou Steel through adopting the composition design of medium carbon + high manganese + microalloying as well as reasonable technology and measure of controlled rolling and controlled cooling. As a result, the bridge steel with such characteristics as good formability, weldability and low temperature toughness could be produced with volume production.

文章主要阐述了利用包钢稀土钢板材厂先进的炼钢和轧钢装备,通过采用中碳+高锰+微合金化的成分设计和合理控轧控冷工艺措施,找到了生产桥梁钢产品使屈强比≤0.84的工艺方法,形成了可批量生产具有良好的成型性能、焊接性、低温韧性特点的桥梁钢。

桥梁钢  /  屈强比  /  控制轧制  /  控制冷却

In the article, it is discussed the technology for producing the bridge steel products with the yield ratio no more than 0.84 is found out with the advanced steelmaking and steel rolling equipment of Rare Earth Steel Plate Plant of Baotou Steel through adopting the composition design of medium carbon + high manganese + microalloying as well as reasonable technology and measure of controlled rolling and controlled cooling. As a result, the bridge steel with such characteristics as good formability, weldability and low temperature toughness could be produced with volume production.
