In this paper an arc voltage-power compound control system was proposed for developing a vacuum spinning consumable electrode powder ****** furnace.
本文结合我院研制的旋转电极制粉炉,提出了弧压-功率复合控制自耗电极位置的方案。
Therefore, the law of welding seam back chipping was stu***d based on the newly developed automatic back chipping machine with a disk-type non-consumable electrode.
因此,本文基于新研制的非熔化盘式电极自动清根技术,对焊缝清根规律进行了研究。
The removal of non-metallic inclusion during remelting occurred mainly in stages of formation of dropets on the consumable electrode tip and dropets falling through the slag.
电渣重熔过程中非金属夹杂物的去除主要发生在自耗电极端头熔滴形成期以及熔滴滴落穿过熔渣层阶段。
Electroslag remelting's consumable electrode current is determined by the distance between electrode and slag bath which is determined by the rotate speed of motors driven by electrode.
电渣重熔的自耗电极电流大小取决于电极与渣池的距离,而该距离大小又取决于电极驱动电机的转速。
Preferably the barrier is built up using an arc having a consumable electrode and it is further preferred that the part of the region against the barrier is built-up by submerged arc welding.
最好的屏障是建立了一个弧形使用了耗电,并进一步希望,该区域的一部分是对隔离墙建成的埋弧焊。
Consumable Electrode(自耗电极) 指在电弧焊接过程中,既作为产生电弧的电极,又作为填充金属熔化并过渡到焊缝中的金属棒或金属丝。其核心特征在于它在焊接过程中会被持续消耗熔化,成为焊缝金属的一部分。
其详细含义和工作原理如下:
核心定义与作用:
工作原理: 在电弧焊中,电流通过电极与工件之间形成电弧,产生高达数千摄氏度的热量。该热量同时熔化电极的端部和工件的待焊部位,形成熔池。熔化的电极金属(熔滴)在各种力(如重力、电磁力、表面张力离子流力)的作用下,脱离电极末端,穿过电弧区,落入熔池并与熔化的母材金属混合。随着焊接的进行,电极持续送进,熔化,过渡,消耗,最终成为焊缝的一部分。熔敷金属量(Deposited Metal)可近似用以下公式估算: $$ W_d = k_m cdot I cdot t $$ 其中,$W_d$ 为熔敷金属重量,$k_m$ 为熔敷系数(与电极材料、药皮/保护气体、电流极性等有关),$I$ 为焊接电流,$t$ 为电弧燃烧时间。
