摘要

为解决南京钢铁股份有限公司研制的Q460FRE耐火钢的焊接问题，进行配套焊接材料J460FR焊条的研制。研究了不同化学成分下焊条熔敷金属的力学性能，以及Mo含量对熔敷金属抗二次火灾能力的影响，并对新研制的J460FR焊条进行了焊接工艺评定。结果表明：J460FR焊条的熔敷金属具有良好的综合力学性能和一定的耐火能力；Mo含量对焊缝的高温拉伸屈服强度有较明显的影响，且Mo含量在0.1%~0.5%时效果最为显著；在600 ℃×3 h的模拟二次火灾条件下，也能保证较高的强度；焊条具有优良的焊接工艺性能和操作性能，均满足设计要求，可以用于Q460FRE耐火钢的焊接。

Abstract

In order to solve the welding problem of Q460FRE fire-resistant steel developed by Nanjing Iron & Steel Co., LTD., the supporting welding material J460FR electrode was developed. The mechanical properties of the deposited metal under different chemical compositions and the effect of Mo content on the secondary fire-resistance of deposited metal were studied, and the welding procedure of the newly developed J460FR electrode was evaluated. The results show that the deposited metal of the newly developed J460FR electrode has good comprehensive mechanical properties and certain fire resistance, Mo content has an obvious effect on the high temperature tensile yield strength of weld, and the effect is the most significant when Mo content is 0.1%~0.5%; Under the condition of simulated secondary fire at 600 ℃ for 3 hours, the high strength can also be ensured; The electrode has excellent welding process performance and operation performance, and meets the design requirements, which can be used for the welding of Q460FRE fire-resistant steel.
