Abstract
Technology of manufacturing cathodic plate for electrolytic zinc by casting-forging is characterized in that directly aluminium sheet (3) being cast into wherein when casting conducting beam (2) in the die cavity of preheating and inclination, simultaneously with the disposable casting of hanger (1) on conducting beam (2).The negative plate that adopts technology die casting of the present invention to make is smooth smooth, no thermal crack and wave transformation phenomenon, and resistance is little.Use the die casting cathode plate for electrolyzing zinc and can boost productivity about 10%, the corresponding energy-conserving action that risen.
Description
The invention belongs to chemical technology field, particularly the manufacturing process of cathode plate for electrolyzing zinc.
At present, the negative plate that each electrolytic zinc plant of China uses is to adopt weldprocedure to make, and is about to the aluminium sheet of bulk-breaking, and cast aluminium conducting beam and hanger combine with weldprocedure.Its weak point is to exist liquid aluminium liquid can fuse hydrogen (H2) in a large number in welding process, impels it to remain in and is gathered into pore in the weld metal, easily generates fine and close oxide film (Al
2O
3), be in contact with one another badly between conducting beam and the aluminium sheet thereby cause, be difficult for fine and closely also producing thermal crack, make after the combination negative plate not only resistance produce wave transformation more greatly but also easily.
The objective of the invention is provides a kind of technology of manufacturing cathodic plate for electrolytic zinc by casting-forging at having above weak point in the welded cathode plate Technology.
The said die casting of the present invention is made electrolytic zinc and is meant with negative electrode utmost point technology and directly aluminium sheet (3) is cast into wherein when casting conducting beam (2) in the die cavity of preheating and inclination, simultaneously with the disposable casting of hanger (1) on conducting beam (2).
Fig. 1 is the cathode plate for electrolyzing zinc front view made from the said technology of the present invention.
Fig. 2 is the synoptic diagram that is drilled with staggered aperture on aluminium sheet.
Fig. 3 is Fig. 1 a-a face sectional view.
Die cavity 10 °-20 ° the synoptic diagram that tilts when Fig. 4 is the die casting negative plate.
The invention will be further described by embodiment below in conjunction with accompanying drawing
As shown in Figure 2, imbed on the aluminium sheet (3) of conducting beam (2) one ends and be drilled with some staggered apertures (4), staggered purpose is in order to form some facets.These imbed conducting beam plane partly is to have removed oxide film (Al before casting
2O
3), when temperature is that 720 ℃～750 ℃ fused aluminum metal liquid die cavity of flowing through solidifies and produces when shrinking, the effect by interior the aluminium liquid of each aperture (4) crystallization contraction is clamped in aluminium sheet (3) in the conducting beam (2).
As shown in Figure 3, aluminium sheet (3) cross section of stretching in the conducting beam (2) accounts for 20.8% of conducting beam (2) total cross-section, length of embedment be conducting beam (2) cross section high 80%.
As shown in Figure 4, for improving the flowability of molten metal in die cavity, die cavity is preheated in 380 ℃～450 ℃ scopes before the casting, and die cavity is the 10 °～20 ° of casting of tilting.
In the present embodiment, the material of hanger (1), conducting beam (2) and aluminium sheet (3) is No. 1 aluminium ingot and aluminium sheet, does not add any material in the die casting.
The negative plate that adopts technology die casting of the present invention to make is smooth smooth, no thermal crack and wave transformation phenomenon, and resistance is little.
Use the die casting cathode plate for electrolyzing zinc and can boost productivity about 10%, the corresponding energy-conserving action that risen.
