Water supply for each of them can be regulated separately with pressure gauge, which makes it a benefit for cast bar to be cooled evenly and crystal grain to be refined with high adaptability in process control. Pneumatic tensioner, with a regulator, is applied to steel tape. Once the tension is set, the steel tape keeps constant in force so as to produce aluminum alloy bar in high quality. The continuous rolling machine is of two-roller plus three-roller type. It helps to intensify the deformation of cast bar under high temperature. The cooling and lubrication emulsion is supplied in two routes, one of which is for gears and bearings, and the other is for inlet and outlet positioning guides. The flow of the latter is regulated separately because it greatly affects the temperature of the rolled bar, making it easy for process control. The quenching and coiling unit has in-line cooling function to ensure the temperature of the finished rod to be adjustable. The coiler is in twin-basket type. Electrical control system: The production line, driven by DC motor, is provided with Siemens fully digital DC speed regulator in host machine and drive motor. The controller is equipped with Siemens PLC and man-machine interface screen to display parameters and fault or trouble. 7.Items to be Prepared by User 7.1.
