This application includes companies engaged in rolling, drawing, and extruding aluminum alloy basic shapes such as plate, sheet, strip, bar, and tubing. In the process of continuous casting of aluminum, coolants and industrial water are used to cool the caster wheel or caster belt, lubricate mill components and transfer aluminum particulate and contaminants to filtration systems using gravity filters, Hydro Band Filters or Double Disc Filters. Particulate and contaminants are removed by the filter and system pumps transfer clean coolant back to the work. Continuous casting produces aluminum rod, sheet and rolled products as well. Complete system packages including tanks, pumps, heat exchanger and controls.
