Abstract
The present invention discloses a complete set of aluminizing, adhering and casting processes of a steel casing aluminum core anode claw. The steel casing aluminum core anode claw manufactured by the process method can ensure that an aluminum core and a steel casing are sufficiently aluminized and adhered, and the conductive performance of the steel casing aluminum core anode claw is much better than that of the steel casing aluminum core anode claws manufactured by the original casting methods and cast steel anode claws in common use. Pressure drop values of practical measurement are less than 20 muV, the decreasing range of the pressure drop values can be more than 50% than that of the original various anode claws, and electricity saving and consumption decreasing effect is obvious. The process method can also be used for the composite adhesion or the adhering casting of aluminum and steel of other various components.
Description
Technical field
The present invention relates to a kind of casting technique of aluminum steel adhesive composite materials conductive component, specifically is electrolgtic aluminium box hat aluminium core anode claw aluminising bonding casting technique.
Background technology
Original box hat aluminium core anode claw adopts in the anode claw box hat cast aluminum liquid or casting method such as pressurize behind cast aluminum liquid is made, these methods are because aluminium core and steel sheel can't bond and produce the slit at all, and the box hat aluminium core anode claw of being cast can't reach the excellent conducting performance requirement.
Summary of the invention
Purpose of the present invention: the deficiency at the existing casting method of above-mentioned box hat aluminium core anode claw cast component exists, a kind of new casting method is provided, solve the problem of aluminium core and box hat bonding casting, reach good electric conductivity requirement with guarantee.
The scheme that the present invention realizes is to adopt this process that the anode claw box hat is immersed aluminising bonding casting in the aluminium liquid, this process comprises the process of foundry goods installation rising head, casting, cooling, cutting rising head, removing surface, it is characterized in that box hat is through after cleaning treatment, the drying, steel sheel is immersed aluminising in the aluminium liquid, after finishing, aluminising takes out steel sheel, guarantee to fill or to fill with aluminium liquid in the steel sheel, make aluminium liquid arrive the rising head top, naturally cool to normal temperature, cut rising head again, obtain finished product after the outer surface cleaning.
The main technique flow process:
1. steel sheel cleaning treatment-2. dry-8. steel sheel immerse the steel sheel that aluminising in the aluminium liquid-4. take out fills aluminium liquid-5. clear up convex connect aluminium slag around the aluminium handle mouth-6. install convex aluminium handle mould and rising head-7. replenish inject aluminium liquid to the rising head top-8. be cooled to the finished product of normal temperature-9. cut rising head, cleaning-10.
The specific embodiment
The main technique method of operating:
1. steel sheel cleaning treatment: after the slagging-off cleaning of steel sheel surface, (avoiding cleaning to non-aluminum steel adhesive surface) cleaned in the decontamination that eliminates rust to the aluminum steel adhesive surface, and cleaning fluid can be selected pickle for use, ensures fully rust cleaning decontamination.Clean the back steel sheel and dry, brush carbon dust or other fireproof coatings to avoid the aluminium liquid that bonds at non-aluminum steel adhesive surface.
2. dry: air dry or heating 100C are following dry, note avoiding the surface oxidation that cleaned.
3. steel sheel immerses aluminising in the aluminium liquid: the time that box hat immerses aluminium liquid delay aluminising is no less than 2 minutes.Immerse the best time of being detained aluminising of aluminium liquid, determine according to aluminium liquid weight, temperature, steel sheel wall thickness and weight in the aluminium liquid pool.
4. take out the steel sheel that fills aluminium liquid: box hat aluminising time in aluminium liquid when taking out box hat, must fill aluminium liquid or fill with aluminium liquid after reaching preset time in the box hat.
5. clear up convex and connect aluminium handle mouth aluminium slag on every side
6. convex aluminium handle mould and rising head are installed: aluminium handle mould can be used steel plate, cast iron or other materials manufacturing.
7. replenish and inject aluminium liquid:, before aluminium liquid solidifies in box hat, replenish and inject enough aluminium liquid according to the needs of workpiece to the rising head top.
8. be cooled to normal temperature: naturally cool to normal temperature,
9. cut rising head, cleaning.
10. finished product; Product inspection is qualified can put in storage.
The box hat aluminium core anode claw that aluminising bonding casting technique of the present invention is made, aluminium core and box hat bonding back tensile strength can reach or near the intensity with trade mark cast aluminium, guarantee that aluminium core and box hat are well-bonded, and ensure that its electric conductivity reaches designing requirement.Test result shows, the box hat aluminium core anode claw of this process aluminising bonding casting, its excellent electric conductivity surpass box hat aluminium core anode claw that original casting method makes and the general cast steel type anode claw in the use significantly.Practical test voltage drop value reaches below the 20mV, reduces amplitude than original various anode claw voltage drop values and can reach more than 50%, obviously reduces power consumption, enhances productivity.Simultaneously,, can also significantly reduce installation cost, reduce anode claw and come off and maintenance cost owing to cancelled the blast weld tabs that original cast steel type anode claw is connected with the conductive aluminum bar.This process is simple to operate, and properties of product are stable, and production cost is no more than former cast steel type anode claw.Possessed the adequate condition that comprehensively substitutes cast steel type anode claw.In addition, this process can also be used for other various bondings of parts aluminum steel composite in addition or bonding casting.Market prospects are very wide.
