The continuous casting machine consists of upper and lower pouring pots, aluminum liquid temperature measuring device, flow regulating device, crystallization wheel and rotating device, pressing wheel device, steel tape tensioning device, idler wheel, steel tape air blowing and water wiping device, ingot picking device and oiling device, ingot approach bridge, stainless steel water cooling device, water pressure display, electromagnetic flowmeter flow display and gas system, etc. All components are installed on an integral box, and the continuous casting machine is an integral casting machine, which is convenient and quick to install and adjust.

In order to ensure dense and uniform crystallization of the ingots, the crystallization wheel is cooled by spraying water from all sides. The cooling water is managed in zones, and each section of the pipeline is equipped with a manual water control regulating valve and a flow meter display instrument, and has a pressure display. In order to facilitate cooling water adjustment and maintenance, internal cooling, external cooling, and side cooling are installed on a pneumatically propelled platform, which can be easily pushed out from the crystallization wheel. The cooling system of the casting machine is closed, and the water vapor generated when cooling the crystallization wheel is sucked out by the induced draft fan to the outside, so as to avoid air holes and air bubbles caused by the aluminum liquid suction.

The continuous rolling machine is composed of motor, coupling, feeder, roughing mill, finishing mill, planetary reducer, transmission gearbox, base and so on.

The qualified billet produced by continuous casting is sent to the continuous rolling machine through the feeding device, firstly passes through four two-roll stands for rough rolling, and then enters eight two-roll stands for finish rolling, and the rolled aluminum/aluminum alloy rods are sent out to the take-up.

The gearbox gears of the finishing mill are all made of 20CrMnTi material and ground, the stand bearings are made of NSK bearings from Japan, the rolls of the finishing mill are made of H13 material, and the lubricating and cooling water pipes of the rolling mill stand are made of hoses and contain quick connectors.

The rolling mill is equipped with a fume collection system to send the flue gas out of the plant. The rolling mill is equipped with a protective cover, which is in the form of a hydraulic flip cover to prevent emulsion splashing and smoke collection, and is equipped with a visible cover plate for daily inspection.

The rod take-up system is mainly composed of an operating platform, a guide tube, an arc-shaped raceway, a rod swing device, and a double-basket take up trolley, etc.

The rolled aluminum/aluminum alloy rods are sent into the conduit device, and then enter the rod swing device. When the speed of the rod swing transmission device is fast, the coiling diameter is small; when the speed is slow, the coiling diameter is large, and the speed can be adjusted steplessly.

When the aluminum/aluminum alloy rod falls into the rod take-up basket, the rod take-up system can realize free landing centrifugal type and automatic plum blossom type. The coiling diameter of the aluminum/aluminum alloy rods is automatically controlled by PLC without manual adjustment.

There is a driving device under the trolley, which is driven to change the basket. If the aluminum/aluminum alloy rods need to be cooled and quenched, the water valve can be opened, then the cooling water can spray on the surface of the aluminum/aluminum alloy rods for quenching treatment, and the cooling water is sprayed into the water bag of the take-up pipe by adjusting the water volume switch. The inside of the tube plays a role of cooling and lubricating the aluminum/aluminum alloy rods, and the amount of water can be adjusted according to the requirements to control the soft and hard strength of the aluminum/aluminum alloy rods.

Continuous casting machine, front traction and feeder adopt Siemens frequency converter for speed regulation, and DC motor of continuous rolling machine adopts DC speed regulation and synchronous control.

The PLC uses Siemens S7-1200 for programming, and the touch screen uses Siemens KTP1200 color touch screen (man-machine interface) for operation. The touch screens of the man-machine interface and PLC perform two-way data exchange, and the monitoring and control of the system is realized through PLC program control. It can accurately and reliably command and coordinate the work of the entire system, and various operating parameters are centrally monitored and displayed. Real-time monitoring and data collection and storage are carried out on the equipment through the industrial computer, and the hourly output, cumulative output, coiled weight and process parameters in process management can be displayed online. The expandability of the equipment is strong, facilitating the collection of production data. The centralized control device of the equipment must reserve an Ethernet interface for communication with the upper computer.

When a single machine is running, the speed of the casting machine, front tractor, rolling shear, rolling machine, and rod coiling can be individually adjusted through the console. During linkage operation, the speed of the entire line is based on the speed of the casting machine, the front traction machine, rolling machine, and the coiler automatically track the speed of the casting machine. The linkage speed is provided with speed fine-tuning for the front tractor and rolling mill.

The process flow of the whole production line is visually displayed with full animation, which can conveniently issue operation instructions and check the operation status of the equipment. At the same time, the system will give an abnormal prompt to the current and motor speed, and the continuous rolling mill will automatically alarm and stop automatically when the rods are blocked and piled up.

The electric control cabinet part should be placed in a dedicated power distribution room, the main operating console should be placed in the control room, and only the pole winding machine operation auxiliary table and emergency switch should be placed on the production site. Schneider products are used for buttons, indicator lights, control relays, and low-voltage electrical appliances below 65A.
