Embodiment Construction
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] Such as figure 1 , figure 2 with image 3 As shown, this embodiment provides a hot-rolling system for aluminum strips, including a pusher heating furnace 1, a hot roughing mill 3, a heavy shear 5, a light shear 6, and a stacker arranged in sequence along the rolling direction of the aluminum alloy strip 7. The hot roughing mill 3 includes work rolls and back-up rolls, and spray beams 8 are arranged correspondingly to the work rolls and back-up rolls....

The invention provides an aluminum strip hot rolling system which solves the problem in an existing hot mill that a spraying beam is difficult to maintain due to the fact that an electromagnet of a control nozzle is easy to damage. The aluminum strip hot rolling system comprises a push type heating furnace, a hot roughing mill and a heavy shearing and light shearing stacker crane which are sequentially arranged in the rolling direction of an aluminum alloy belt, a main rolling mill comprises a working roll and a supporting roll, spraying beams are arranged corresponding to the working roll and the bearing roll, each spraying beam comprises a plurality of nozzles and a spraying beam arm, the nozzles are fixed to the spraying beam arm, the spraying beam arm is divided into a plurality of areas, the nozzles in each area are communicated to an oil supplying pipe through branch pipes, and a pneumatic control valve is arranged on the pneumatic control valve. The pneumatic control valve is adopted in the aluminum strip hot rolling system, the requirement for emulsion of production process is met, reliability of stopping and starting is ensured, and meanwhile labor strength of maintenance personnel is further reduced. The most important is that the bad results that the rolls are damaged and plate belt winds around the rolls caused by the fact that insufficient cooling of hot rolling are avoided.
Description
technical field [0001] The invention relates to the technical field of aluminum processing, in particular to an aluminum strip hot rolling system for processing aluminum alloy strips. Background technique [0002] At present, in the hot rolling process of aluminum processing, hot rolling mills are mainly used for processing. The hot rolling mills use electric motors to drag the aluminum alloy strips, and use the backup rolls and work rolls of the hot rolling mills to jointly apply force to the two sides of the aluminum alloy strips. face. The purpose of rolling hot-rolled aluminum sheets and strips with different thicknesses is achieved by changing the size of the gap between the two rolls. [0003] The nozzle injection beam of the rough rolling of the hot rolling mill is installed on the tension frame at the entrance and exit side of the rough rolling mill. It is mainly used to cool and lubricate the work rolls of the rolls. It is required to control the nozzles in differe...
