Problems solved by technology

However, it is impossible for the rolling directions of adjacent passes to be perpendicular to each other to complete the rolling of hundreds of meters of lead strip; too much annealing treatment makes the production process complicated, the annealing temperature is high and the annealing time is longer. The increase rate of the proportion of the circle tends to decrease with the increase of the number of annealing

Abstract

The invention relates to a method for producing a lead belt of a battery plate. The technical scheme is that lead alloy for manufacturing the lead belt of the storage plate is performed with melting, continuous casting and rolling, and the thickness of a finished product of the lead belt of the battery plate is 0.4-1.2mm; and rolling reduction rate of pre-rolling pass of the finished product of the lead belt of the battery plate and rolling pass of the finished product of the lead belt of the battery plate is 22-44%. Thermal treatment is respectively performed before and after the rolling pass of the finished product of the lead belt of the battery plate, the thermal treatment temperature is 240-290 DEG C, and the heat preservation time is 8-356 seconds. The chemical components of the lead alloy for producing the lead belt of the battery plate contain: 0.04-0.1wt% of Ca, 0.9-1.8wt% of Sn, 0.01-0.03wt% of Al and the balance of Pb. The method for producing the lead belt of the battery plate has the advantages of being simple in production process, and the prepared lead belt of the battery plate is strong in corrosion resistance.

Description

Technical field [0001] The present invention is a field of preparation technology for lead bands.In particular, it involves a preparation method for batteries. Background technique [0002] Positive and negative plates are important parts of lead -acid batteries.As the carrier of active materials and current, the pole plate often has severe corrosion due to anodized during use, which greatly affects the life of the battery.It is a relatively common method to increase the corrosion resistance of the lead -based alloy polar plate by adding alloy elements. Although this method can alleviate the corrosion of the plate to a certain extent, the addition of the element will cause difficulty processing of the plate processing difficulty and will produce the difficulty of processing the plate processing.When the battery is charged, hydrogen output affects the performance of production and product performance, and the cycle life of the battery is not ideal. [0003] The method of optimizin...
