The Aluminium Cold Rolling Mill uses aluminum cast-rolled coils or hot-rolled coils as blanks. After multiple passes of rolling, the finished coils are rolled out to provide blanks for plate finishing and aluminum foil production. It can provide high-quality, high-precision aluminum plates with a wide range of applications, including the manufacturing of automobile bodies, chassis and parts, and aerospace materials.
During operating, the uncoiler unit is used to uncoil the coils, transport them to the main machine for rolling, and generate back tension stress during rolling. The reduction box can slide freely under the control of the centering system to ensure that the center of the coil is consistent with the center of the machine train. Two DC motors are driven in series, and the use of mechanical gear shifting ensures the tension needs of strips of different thicknesses.
Roll cooling system sprays high-efficiency coolant to the rolls through the spray beam installed at the entrance of the rolling mill. The multi-nozzle and independent flow adjustment system can achieve segmented cooling of the rolls and effectively control the roll shape.
Lubrication system is divided into two parts: thin oil lubrication and oil-gas lubrication. The thin oil lubrication system provides reliable guarantee for the normal operation of the decoiler gear reduction box, main engine gear reduction box, and coiler gear reduction box; the oil-gas lubrication system provides reliable oil-gas lubrication for the roll bearings and guide roller bearings, providing reliable guarantee for high-speed operation of rolling mill.
Electronic control system is divided into AC motor control center, DC transmission system, operating console and automation control system PLC of mill, Schneider filter control system, automatic thickness control (AGC) system, and X-ray thickness gauge.
The whole set of automatic co2 extinguish system is provided to guarantee extinguishing fire. In the area of inflammable,co2 nozzle and temperature testing detector are set. And there are two control methods of fully automatic and manual to make sure timely and reliable fire extinguishing and protect the normal production of the rolling mill.
Our Aluminium Cold Rolling Mill has an advanced automatic thickness control system and a complete plate shape control method, which can provide multiple control methods such as roll tilt, positive and negative bending control of work rolls, and segmented roll cooling, so as to ensure the thickness accuracy and shape accuracy of rolled products are optimized.
Customized design according to the actual needs of customers.
Equipped with various complete auxiliary systems, such as accurate automatic strip centering system, safe and reliable CO2 automatic fire extinguishing system, lubrication system, dry air purging device, smoke recovery device, etc., providing a reliable guarantee for the production of excellent products.
The cold rolling mill is highly automated, and the DC motors are powered by advanced fully digital thyristors, and PLC is used for digital logic operations, parameter setting, and automated process control.
Cold rolling is rolling below the metal recrystallization temperature. Dynamic recrystallization will not occur during the rolling process. The product temperature can only rise to the recovery temperature, so cold rolling will produce work hardening. After aluminum and aluminum plates are cold rolled, the strength and deformation resistance of the material increase, and the plasticity will also decrease. Cold rolling is widely used. Products that require continued rolling after hot rolling and have higher requirements for performance, structure, surface quality and dimensional accuracy must be cold rolled. Cold rolling is mainly used to produce aluminum and aluminum plates that cannot be strengthened by heat treatment.
