6 FAQs about [Lead-acid battery grid continuous casting principle]
What is the difference between continuous strip casting and lead alloy casting?
Fig 2 is the lead alloy version of continuous strip casting, the main difference here is the use of a single rotating drum rather than the two cooled rollers for metals of much higher melting points. Up to the mid-1980s lead alloy grid production was almost exclusively carried out by gravity book mould and pressure-die casting.
How can a lead alloy grain structure be manipulated?
The mechanical and chemical properties as dictated by the lead alloy grain structure can be manipulated by control of rolling pressures and degree of deformation. Very corrosion resistant and stronger grids can be produced by suitable control of these parameters.
What is a continuous grid strip?
The continuous grid strip is subsequently rolled to obtain very thin grids. A stamped grid is made by stamping or punching the grid from a continuous sheet of either a rolled or a continuous-cast lead material. The extent of rolling and the alloy composition determine the final microstructure and the resulting properties of the grids.
What is continuous strip casting?
Continuous strip casting is one of those processes that not only provides significant benefits to the battery manufacturer but also helps to establish the credentials of lead-acid chemistry as a reliable technology for the future.
Why is continuous strip casting not accepted?
Nowadays, the quality issues seem to have been largely resolved and, as already noted, continuous strip casting is commonplace in the lead-acid battery manufacturing world. However, there are several reasons for it not being universally accepted for all battery and grid types. These depend on the application and the battery design.
How fast can a gravity cast grid be made?
These continuous methods enormously improved production output for grids. The normal manufacturing rate for gravity cast grids would be around 12 to 15 double panels per minute, compared with speeds in the region of 400 per minute with continuous strip methods.
