1. Introduction

The production line is mainly composed of casting machine, auxiliary machine, continuous rolling mill, quenching & take-up device and emulsion cooling system, lubrication system for gearbox, electric control system, external cooling water system. lts easily scalable device configuration, can produce Ф9.5mm, Ф12mm, Ф15mm EC aluminum rod. To produce Ф9.5mm EC aluminum rod adopts 15 stands, to produce Ф12mm EC aluminum rod adopts 13 stands, to produce Ф15mm EC aluminum rod adopts 11 stands.
Adopting four-wheel horizontal casting machine, it is the most advantage continuous casting machine in China: Realizing the automatic flow control, horizontal casting, reducing operators, ensuring the liquid aluminum can be cast smoothly, no turnable, overcoming the defects such as slag inclusions and pores of the aluminum rod inside and the product quality is greatly improved.

The qualified aluminum molten liquid pass through the launder and enter into horizontal casting machine. It continuously cast into 2340mm2 trapezoidal ingots. The waste ingot is cut by shearer machine. Then the cast ingots enter into the continuous rolling mill, which produces aluminum rod. Finally the rod pass through the non-butter leading pipe and Plum Blossom Coiler, and then become the finished products.

The rolling mill adopts automatic feeding, and the Y-type three-roller stands are arranged alternately with upper and lower transmissions. When a failure occurs during the rolling process and causes an overload, the shear sleeve in the safety coupling cuts off the safety pin to protect the transmission gear and shaft from damage.

Roller type non-butter leading pipe and dual basket drop coiler device----no butter, energy saving and emission reduction; no scratches on the whole passway; innovative structure makes the deformation force and coil release force of the aluminum rod in the best state, the coil shape is good; the dual basket drop coiler take-up device solve the aluminum rod hard outside and soft inside problem.

Openable take-up frame, easy to take out the coil. The take-up trolley is equipped with a brake through the track to facltate the positioning of the fake-up frame. Through the frequency conversion control of the reducer motor, it is possible to switch between the large and small coil and the drop coiler take-up. The improved take-up is more conducive to heat dissipation and makes the internal strength of the product relatively stable.

The electric drive control adopts the DC main motor and the advanced Siemens full digital speed control device to synchronize the speed of the casting machine, the rolling mill and the take-up device and the two-way data eychange with the PLC through the human-machine interface touch screen in the Ethernet communication mode, through the PLC.
