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.
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.
It was in the 1980s that Cominco, now BTS (Battery Technology Solutions), developed a process that produced a thin, continually cast strip of lead-calcium alloy, which was rolled and stored before processing into battery grids. Fig 1 shows the general principle of continuous casting molten metal into strip form.
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.
Up to the mid-1980s lead alloy grid production was almost exclusively carried out by gravity book mould and pressure-die casting. The main driver for the development of continuous strip production was the introduction of new grid alloys using calcium rather than antimony as the hardening agent.
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.
