Description
Technical Field
The application relates to the technical field of anode conductive devices, in particular to an anode conductive device, a steel-aluminum connection method, a steel-aluminum connection structure and a steel-aluminum composite sheet thereof.
Background
The anode conductive device used in the electrolytic aluminum industry consists of an upper aluminum anode guide rod and a lower steel anode steel claw, and in the production process of the prebaked anode aluminum electrolysis cell, the connection between the anode guide rod and the anode steel claw is very important, and the connection quality between the anode guide rod and the anode steel claw can directly influence the working efficiency and the electricity consumption of the electrolysis cell.
In the prior art, because the steel and the aluminum cannot be directly welded, the anode guide rod and the anode steel claw are welded together in a steel-aluminum explosion welding block transitional connection mode. When the anode conductive device is manufactured, the aluminum plate surface of the explosion welding block and the aluminum anode guide rod part at the upper part of the anode conductive device are welded by argon arc welding, and the steel plate surface of the explosion welding block and the steel anode steel claw boss at the lower part of the anode conductive device are welded by common electric welding.
For example, patent document CN202430299U discloses a method for welding a combined anode steel claw with a steel plate, wherein a beam of the anode steel claw is vertically welded with two aluminum steel composite explosion welding pieces, and is in clamping elevation welding connection with an aluminum guide rod. The problems that exist are: when the aluminum steel composite explosion welding piece is welded with the anode steel claw, the electric welding can only weld at the periphery of the contact surface of the aluminum steel composite explosion welding piece and the anode steel claw, and the welding area is small.
In addition, patent document CN110257860a discloses a composite-molded anode conductive device and a method for manufacturing the same, wherein a composite member composed of a steel base plate and an aluminum base plate is used to connect an anode guide rod and an anode steel claw, and a bottom groove for steel welding is provided at the bottom of the composite member. When the aluminum-aluminum composite component is used, the steel substrate plate of the composite component and the anode steel claw are fixed through the steel-steel welding point, and the aluminum substrate plate of the composite component and the anode guide rod are fixed through the aluminum-aluminum welding point. In the anode conductive device, the bottom groove is arranged at the bottom of the composite part, so that the welding area between the composite part and the anode steel claw can be increased, but the welding area is still smaller than the whole contact surface.
In the prior art, when the anode steel claw is welded, the welding area is smaller, and only 30% -35% of the whole contact surface is formed, so that the resistance between the anode guide rod and the anode steel claw is larger, and the large current flowing through the anode steel claw through the anode guide rod in the production process is blocked in an explosion welding block area, so that large contact pressure drop and severe heating are generated, and the electricity consumption is increased; in addition, the heat generated in the production process is relatively high, and the thermal expansion coefficient of aluminum is about three times that of steel, so that cracks are easily generated at the joint surface of aluminum steel during long-time working, the joint surface is cracked, and the connection strength is reduced. In addition, the welding area is smaller, so that the connection strength between the anode steel claw and the anode guide rod is low, the anode steel claw is dropped after the anode conductive device is used for a long time, and the potential safety hazard is large.
