|
摘要
为检验宽带极单层高速电渣堆焊能否满足加氢反应器内壁不锈钢堆焊层的技术要求,依据某公司的"大面积单层带极堆焊加氢反应器研制"项目技术条件,采用90 mm×0. 5 mm钢带单层电渣堆焊、75 mm×0. 4 mm钢带单层高速电渣堆焊和90 mm×0. 5 mm钢带单层高速电渣堆焊按各自焊接规范进行堆焊试验,对堆焊层厚度、化学成分、力学性能、铁素体含量的稳定性、氢致剥离等方面进行检测分析。研究表明,在一定焊接规范下,75 mm×0. 4 mm和90 mm×0. 5 mm钢带单层高速电渣堆焊技术可用于加氢反应器筒体内壁不锈钢层的堆焊。
In order to test whether the monolayer high-speed electroslag surfacing with wide strip electrode can meet the technical requirements of stainless steel surfacing on the inner wall of hydrogenation reactor,according to the technical conditions of a company's project "Development of Hydrogenation Reactor Made by Large-area Single-layer Strip Electrode Surfacing",surfacing tests were carried out by performing monolayer electroslag surfacing with 90 mm × 0. 5 mm steel strip,monolayer high-speed electroslag surfacing with 75 mm × 0. 4 mm steel strip and monolayer high-speed electroslag surfacing with 90 mm × 0. 5 mm steel strip according to their respective welding specifications,and the thickness,chemical composition,mechanical properties,stability of ferrite content and hydrogen-induced disbanding,etc. of deposited layer were tested and analyzed. The research results show that the monolayer high-speed electroslag surfacing technology with the steel strip of 75 mm × 0. 4 mm and 90 mm × 0. 5 mm can be used for the stainless steel surfacing on the inner wall of the hydrogenation reactor cylinder under specified welding specifications.
