ULL+ZRT Aluminum Or Aluminum Alloy Continuous Casting And Rolling Line

Application
This production line applies the aluminum or aluminum alloy to produce Φ7.6mm, Φ9.5mm, or Φ12mm aluminum rod, through the continuous casting and rolling processes.

Advantages of the Continuous Casting and Rolling Line
1. The casting machine is of four wheel type structure, minimizing the distortion and crack of the cast ingot.
2. Flow of the chamber machine is automatically controlled.
3. There are four cooling areas. Each area has 3 sections. In total, we have 12 valves to control the flow. All of them can be individually controlled on the ground.
4. Two tensioning wheels are separately installed on the upper part and lower part. Being pneumatically controlled, the wheels have no such problem as aluminum leakage. They are easy, convenient to operate.
5. Our casting equipment applies the horizontal casting form. That is why the casting is stable and reliable.
6. Diameter of the crystallization wheel diameter is Φ2200mmmm, and the cross section of the casting ingot is 3807. Linear velocity of the rolling mill is 12m/s. Moreover, the output is about 10t/h.
7. By using the 2+2+12 rolling form, the four two-rollers can better roll the cast ingot of large cross section, reducing the generation of contraction cavities.
8. The aluminum rod continuous casting and rolling line applies the plum blossom form coiling. The coiling is tight. No twining appears.

Improvement
1. Four-wheel type continuous casting machine is utilized.
2. Crystallization wheel diameter and cross area are increased.
3. The flow is automatically controlled.
4. The coiling trolley motor is on the right side of the chassis. It is convenient for connection and maintenance.

Technological Process
Aluminum and Alloy Ingot → Vertical Furnace → Kettle Furnace → Launder →Pouring Ladle → Four-wheel Horizontal Continuous Casting Machine → Front Traction Apparatus →Automatic Shear + Hydraulic Shear → Straightener → Induction Furnace → Feeding Device → Two-roll, Three-roll Continuous Rolling Mill → Aluminum Rod Quench System → Back Traction Apparatus → Rod Coiler →Rod Coil Vehicle

Sales Performance
This aluminum rod continuous casting and rolling line has been applied by the clients separately from Hongkong,Jiangsu Province, Fujian province, etc. Certainly, it is well accepted by the overseas users. The aluminum rod continuous casting and rolling equipment has been exported to America, India,Turkey, Thailand, and more.
