Embodiment Construction

[0019] 1. Raw materials

[0020] Lead: No. 1

[0021] Calcium: Calcium granules or calcium filings (irregular chalk-like)

[0022] Tin: No. 1

[0023] Aluminum: Grade 3 or Grade 2 (fineness 100-200 mesh)

[0024] 2. Process points

[0025] 2.1 Pressed calcium cake

[0026] The ratio of calcium to aluminum powder is 3:1

[0027] Calcium cake diameter 60mm, pressing pressure 15-20 tons

[0028] The pressed calcium cake is generally used immediately, and if stored, it needs to be isolated from the air

[0029] 2.2 configuration

[0030] First put the 5 / 8 to 2 / 3 lead ingots to be prepared

[0031] The configuration temperature is 480~580℃, the lead liquid is dark red

[0032] The amount of calcium cake added is 0.10% to 0.14% of the amount to be prepared

[0033] Use special pliers to press the calcium cake into the bottom of the molten lead pot to let it explode, and then continue to mechanically stir at a speed of 100-200 rpm for 5-15 minutes. Add tin at 0.4% to 0.7%....

Abstract

It is the positive and negative grating alloy and its process used to process valve control plumbum acid storage plate, which comprises the following steps: to mix the calcium powder and lead powder with proportion of three to one to press into calcium cake; to melt the lead ingot into lead liquid; to join the calcium cake in the lead liquid with evenly mixture ;and to join Tin with contents of 1 úÑí½1.4úÑ or 0.4úÑí½0.7úÑ; then to join remaining lead ingot and to separately process the alloy after evenly mixture.

Description

technical field [0001] The invention relates to the manufacturing technology of lead-acid battery, especially the technology of valve-regulated lead-acid battery. Background technique [0002] The battery's positive and negative grid alloys are one of the key technologies for manufacturing valve-regulated lead-acid batteries, especially the calcium content is crucial. The general-purpose lead-calcium alloys in the prior art are mostly formulated with master alloys, whose calcium content is difficult to control and cannot meet the requirements of various indicators for the production of valve-regulated lead-acid batteries. Contents of the invention [0003] The object of the present invention is to provide a positive and negative grid alloy suitable for a valve-regulated lead-acid battery plate and a manufacturing process thereof. [0004] Positive grid alloy used to manufacture valve-regulated lead-acid battery plates, the alloy contains 0.06% to 0.13% calcium, 1.0% to 1....
