Advanced process and equipment
 Advanced process
There are three production lines in casting house, two“1+1” with 120 tons capacity, one “2+1” with 90 tons capacity. The melting and holding furnaces are hydraulic tilting gas furnaces designed by Otto Junker and manufactured by Suzhou Long Ray. All the casting machines have adopted newest semi continuous low level pit casting technologies of Wagstaff with stable operation, high accuracy of control and safety assurance. Graphite liners are used on the moulds of Wagstaff casting machine, hence ingots with better surface quality can be produced compared with the traditional aluminum moulds. Capacitive sensors are used for metal level control, which have no influence of the smog generated during casting and the control is more accurate and safe. The production lines are equipped with ABB electromagnetic stirring device, on line hydrogen measuring and on line dross measuring system. Melt on line treatment systems include Novelis degassing system, deep bed filter system, Mitsui plate filter and tube filter system. Efficiency of degassing can reach 0.12ml/100g-AL, and filtering efficiency can reach above 98% (Impurities smaller than 10μm).
In addition, one sawing machine from Sermas France and two scalping machines from SNK Japan are part of the production line. Thus mainstream products can be covered with min. specification of 520mm×1000mm×9150mm, max. 640mm×2410mm×9150mm, max. weight of 37.5 tons.

The “1+4” 2600mm hot rolling mill supplied by Siemens and SMS Germany with roll grinders supplied by Herkules Germany is the most advanced large hot tandem rolling line in China with the state-of-art aluminum strip processing equipment integrated with mechanical, hydraulic, electric drive, automatic control, automatic detection and process module technologies. The processing procedures include: heating or soaking, rough rolling, T1 shear, T2 shear, finish rolling, coiling, to high bay storage. Productivity for can body stock is higher than 60kt/a with maximum strip width of 2400mm and minimum thickness of 1.8mm. The mill is equipped with hydraulic adjusting system, CVC plus, work roll bending and multi-zone cooling system and temperature control system, which ensures the exit strip temperature within the requirement range. There is light shear, heavy shear, trimming shear, coiler, scrap handling system and fume exhaust system in the line. F4 is equipped with CVC shifting which can continuously adjust the roll gap and highly adapt to specified rolling parameters, thus coils with good flatness and surface quality can be produced. Seven homogenization furnaces designed by Ottojunker and manufactured by Suzhou long Ray have capacity of 25 ingots for each furnace with maximum weight of 34 tons and maximum thickness of 620mm for each ingot.

Cold rolling line consists of one 25mm single stand cold rolling mill, one 2500mm two-stand cold rolling mill and one 2300mm single stand cold rolling mill supplied by SMS and ABB with max. strip width of 2400mm, min. width of 900mm and max. speed of 1800m/min. The line is equipped with advanced CVC automatic control system with high control accuracy with thickness controlled within ±3μm, on line flatness 5I and off line flatness 10I. Annealing furnaces use nitrogen protection with better surface quality after annealing. A complete set of finishing equipment with high speed trimmer, tension leveler and color coater can meet the requirement for high end can body stock. The 2500mm single stand cold rolling mill is the current widest mill for aluminum rolling in China. Up to date developed cooling technology by SMS is used for interstand cooling which can effectively improve cooling efficiency and realize high speed rolling. The high bay storage supplied by Vollert Germany is the first storage system concurrently connected with hot rolling, cold rolling and finishing lines which can realize fully automatic control and is the center of the whole coil production procedures.

 Production equipment   
The wire rod production line is a continuous casting and rolling line from Continuus-Properzi Italy, equipped with 40 tons melting furnace, on line degassing and filter device. The products with good roundness, surface finish and even dimension are widely used for cables and wires.
