Q345C低合金高强度结构钢板的开发

The Development of Q345C Low-alloy High-strength Structural Steel Plate

根据Q345C低合金高强度结构钢板的技术要求和新钢公司实际情况,采取微合金化和控轧控冷相结合的工艺技术提高钢板综合性能,特别是低温冲击韧性,成功地开发出合格产品。

Based on the technical requirement of Q345C lowalloy highstrength structural steel plate and the pratical conditions of Xinsteel,the suitable process path and the technical requirement is worked out,qualified Q345C plate products are produced,and the paper illustrates that the technology combining microalloying with TMCP is a effective means of developing the synthetical properties of steel plate,especially developing the low temperature toughness of steel plate.
