Description

Technical Field

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

[0002] The production process for copper sheet and strip generally involves smelting, casting, rolling, annealing, and finishing. Rolling is the key step in rolling ingots or billets into sheet or strip, significantly impacting the quality and performance of the copper strip. However, during the rolling process, the copper strip deforms and heats at the rollers. Excessive roller temperatures can affect both deformation and quality.

[0003] Most existing cooling methods are water cooling or oil cooling. However, during the cooling process, the cooling liquid medium is affected by heat, and dirt will be generated in the calendering roller. The dirt adheres to the roller and affects the heat exchange efficiency. In addition, the dirt is unevenly distributed on the inner wall of the roller, resulting in different cooling effects on different parts of the roller. In turn, the temperature control during the calendering process becomes uneven, affecting the calendering quality of the copper strip. However, most existing dirt cleaning methods involve adding descaling agents to the coolant for cleaning, but the descaling effect is poor.

[0004] Based on this, there is an urgent need for a copper strip rolling equipment with a descaling function to achieve uniform heat exchange and improve the rolling efficiency of the copper strip. Summary of the Invention

The adjustment plate 740 can be flexibly moved to adapt to copper strips of different thicknesses, and can reduce the loss of heat in the preheating chamber 710, thereby improving the preheating effect of the copper strip. The winding drum 730 guides the copper strip, and the copper strip is wound around the outside of the winding drum 730, thereby increasing the residence time of the copper strip in the preheating chamber 710, thereby improving the preheating efficiency.

[0077] 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. 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, then the reduction motor 320 is started to drive the first gear 330 to rotate, the first gear 330 engages with the second gear 340 to rotate, and then drives the outer cylinder 240 to rotate, so that 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 engaged with the locking teeth 211 on the support tube 210, and the inner cylinder 220 is locked so that it does not rotate with the outer cylinder 240. Then, cooling oil is input between the outer cylinder 240 and the inner cylinder 220 through the joint 231. At the same time, the water tank 610 inputs cooling water into the inner cylinder 220 through the circulation pipe 630. The cooling oil absorbs the heat of the outer cylinder 240 and conducts it to the cooling water. The cooling water absorbs the heat to achieve cooling of the outer cylinder 240. The water tank 610 The cooling water is circulated for cooling, and the heat dissipation boxes 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 exposed to the high-temperature oil 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 contracts 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 with the cooling water circulation, effectively improving the heat exchange efficiency.
