Description

Technical Field

[0001] The present application relates to the technical field of copper strip production, and in particular to an energy-saving preheating type copper strip rolling equipment. Background Art

[0002] The production process of copper strips is generally divided into smelting, casting, rolling, annealing, finishing and other steps. Among them, rolling is the key link of rolling ingots or billets into plates or strips through rolling mills, which has an important impact on the quality and performance of copper strips. However, during the rolling process, the copper strip will deform and heat up at the rolling point. If the temperature of the rolling roller is too high, it will affect the deformation and quality of the copper strip.

[0003] Most of the existing cooling methods are water cooling or oil cooling. However, during the cooling process, the cooling liquid medium will generate dirt in the calendering roller due to the influence of heat. The dirt attached to the roller will affect the heat exchange efficiency. In addition, the dirt is unevenly distributed on the inner wall of the roller, resulting in different cooling effects in various parts of the roller, which makes the temperature control during the calendering process uneven, affecting the calendering quality of the copper strip. However, most of the existing dirt cleaning methods are to add a descaling agent to the coolant for cleaning, and the descaling effect is poor. Based on this, there is an urgent need for a copper strip calendering equipment with a descaling function to achieve uniform heat exchange and improve the calendering efficiency of the copper strip.

The winding drum 730 guides the copper belt, and the copper belt is wound outside the winding drum 730, thereby increasing the residence time of the copper belt in the preheating chamber 710, thereby improving the preheating efficiency.

[0053] When the energy-saving preheating type copper strip calendering equipment is in operation, the copper strip to be calendered is fixed on the unwinder 160, and according to the required calendering thickness of the copper strip, the adjusting bolt 130 is rotated to make the adjusting frame 120 move up and down relative to the fixing frame 110, and the distance between the two outer cylinders 240 is adjusted. The copper strip passes through the preheating mechanism 700 and enters the calendering mechanism 200, and then the reduction motor 320 is started to drive the first gear 330 to rotate, and the first gear 330 meshes with the second gear 340 to rotate, thereby driving the outer cylinder 240 to rotate, and the copper strip passes through the two relatively rotating outer cylinders. 240, the copper strip is calendered, and the electric push rod 520 is controlled to extend and retract, so that the locking block 530 is meshed with the locking teeth 211 on the support tube 210, and the inner tube 220 is locked so that it does not rotate with the outer tube 240. Then, the cooling oil is input between the outer tube 240 and the inner tube 220 through the joint 231. At the same time, the water tank 610 inputs cooling water into the inner tube 220 through the circulation pipe 630. The cooling oil absorbs the heat of the outer tube 240 and conducts it to the cooling water. The cooling water absorbs the heat to achieve cooling of the outer tube 240. The water tank 610 The cooling water is circulated for cooling, and the heat sinks 620 on both sides dissipate the heat in the coolant through air convection, and the warm air outlet 621 transmits the heat to the preheating mechanism 700. The preheating mechanism 700 uses the heat released by the cooling mechanism 600 to preheat the copper strip entering the preheating chamber 710. The winding drum 730 guides the copper strip to make it stay in the preheating chamber 710 for a longer time, thereby improving the preheating efficiency. The rolled copper strip is output to the winder 170 for winding. Since the cooling water is subjected to the action of high-temperature oil from the outside for a long time, a layer of dirt will be generated on the The inner wall of the inner cylinder 220 is scraped by the descaling mechanism 400, and the electric push rod 520 is contracted to separate the locking block 530 from the locking tooth 211, thereby releasing the lock of the inner cylinder 220. At this time, the inner cylinder 220 rotates with the outer cylinder 240, and the fixed column 420 is always in a stationary state. When the inner cylinder 220 rotates, the scraping frame 450 scrapes the dirt on its inner wall, and the spring 460 provides a certain pressure on the scraping frame 450 to improve the scraping effect. After the dirt is scraped, it can be discharged along with the cooling water circulation, thereby effectively improving the heat exchange efficiency.
