Technical Specifications and Instruction of LGZ-1500/Y

Aluminium Continuous Casting & Rolling Line

 

1. Application

This production line is used to produce conductive aluminum rod of Φ9.5mm,

Φ12mmby means of continuous casting and rolling.

Aluminum rod

2.2.Molten aluminum or prepared aluminum melt flows from the holding furnace into the casting machine via the launder, where it is cast into a trapezoid ingot with a cross-sectional area of 2400mm². The oil hydraulic shearer cuts off the waste end and press it smaller or pointed so as to feed into the rolling machine, where it is rolled, and after passing through the grease box and the guide pipe, aluminum rod is finally laid down in coil in the basket on the trolley.
