破冰船是用于破碎水面冰层的船舶,新型破冰船对破碎冰层厚度提出了新的要求,由于需要在低温环境下工作,钢材需具有较高的力学性能。通过合理的成分调整和严格的工艺控制,研发出高强韧性匹配的新型破冰船用热轧球扁钢,产品性能完全符合相关标准要求。
The icebreaker is a ship used to break the surface ice layer. The new type of icebreaker has put forward new requirements on the thickness of crushed ice layer. Due to the need to work under low temperature environment, the steel needs high mechanical properties. Through reasonable composition adjustment and strict process control, a new type of hot-rolled dome flat bar for icebreakers matching high strength and toughness has been developed. The performance of the product fully complies with relevant standards.
