AI Technical Summary
The existing aluminum alloy casting and rolling roll assembly lacks the ability to dynamically control cooling and rolling force, resulting in uneven cooling causing fluctuations in plate thickness and poor surface quality. The fixed rolling force is difficult to adapt to process changes, easily causing cracks and microstructure segregation, reducing production efficiency and increasing energy consumption.
The transmission components driven by servo motors and temperature sensors, in conjunction with a PLC logic controller, enable dynamic adjustment of the casting roll spacing and cooling intensity. The servo motor drives the casting rolls to rotate and the electric push rod adjusts the spacing. The temperature sensor monitors the heat in real time to control the cooling water flow, thus achieving dynamic control of cooling and rolling force.
It effectively improves the surface quality and production efficiency of aluminum alloy sheets, ensures that the cooling effect adapts to process changes, reduces cracks and microstructure segregation, and lowers energy consumption.
