Aluminum Strip Rolling Mill

Sky Bluer Environmental Technology Co. Ltd manufactures aluminum strip rolling mills that actively reduce the thickness of aluminum strips or sheets by pressing them between one or more pairs of heavy rollers—a process known as rolling. These machines process semi-finished aluminum materials that are already prepared for further thinning and refinement.

Leading Aluminum Strip Rolling Mill Manufacturer from China

Sky Bluer Environmental Technology Co. Ltd, based in China, is a premier manufacturer of aluminum strip rolling mill machines. We specialize in producing high-precision cold rolling mills designed to meet the diverse needs of aluminum processing industries. Our machines deliver exceptional accuracy in thickness and width, with straightness precision up to 0.5mm/m. Combining self-developed cold rolling mills with advanced drawing rolling die technology, we offer cost-effective solutions that enhance product quality. With a focus on innovation and high-precision performance, Sky Bluer is a reliable choice for businesses looking for superior aluminum rolling machinery.

Rolling Mills: Types, Functions, and Material Compatibility

Aluminum Strip Rolling Mills are used to compress metal into consistent thicknesses, form it into specific shapes, and produce custom-sized strips. With a wide range of rolling mill types available, selecting the ideal one depends on the metal being processed and the specific rolling method employed by the manufacturer.

Rolling Mill Applications

Metalworking is often highly customized, which has led to the development of various types of rolling mills, each suited to specific functions. For example, one mill may be optimized for flat rolling, while another is designed for shaping metal using grooved rolls. Although larger mills offer higher rolling load capacities, many projects don't require such scale and are better served by smaller, more specialized equipment.

Conventional Cold Rolling Process

In conventional cold rolling, the single-pass reduction typically ranges from 30% to 70%, depending on several factors:

• Alloy Type: Pure aluminum (e.g., 1xxx series) can tolerate higher deformation (up to 70%), while high-strength alloys (e.g., 7xxx series) require a reduction range of 30% to 50% to prevent cracking.

• Material State: Materials in an annealed state (O-state) can undergo higher deformation, whereas hardened materials (H-state) require reduced deformation to maintain integrity.

• Product Requirements: For thin plates (e.g., less than 0.5mm), multiple rolling passes are required with smaller reductions per pass. For thicker plates, a larger single reduction is possible.

In multi-pass rolling, the total deformation can accumulate to 80% to 90%, but this must be carefully controlled in stages to prevent defects.

Rolling Process Stages and Reduction Rates

• Rough Rolling: The reduction rate typically ranges from 40% to 60%, with the thickness reduced to 0.5–1 mm.

• Intermediate Rolling: The reduction rate is generally between 30% and 50%, bringing the thickness down to 0.1–0.3 mm.

• Finishing Rolling: The final reduction rate is around 10% to 20%, reducing the thickness to 0.02–0.05 mm.

Key Components of an Aluminum Strip Rolling Machine

An aluminum strip rolling machine consists of several key components that work together to ensure efficient and precise operation. The main parts include the rolling stand (with work rolls and backup rolls), the drive system for power transmission, and the hydraulic system to control roll gap and pressure. The cooling system regulates temperature, while the coiler winds the finished aluminum strip. The tension control system maintains consistent tension, and the automation and control system manages parameters like speed and roll gap. The lubrication system reduces friction, and the entry and exit guides align the material. Finally, the inspection and quality control systems ensure the product meets specifications. These components work in unison to deliver stable performance and high-quality aluminum strips.

Company Profile:

Sky Bluer Environmental Technology Co. Ltd is a leading manufacturer specializing in precision cold rolling mills and metal shaping systems. Our product range includes micro-precision cold rolling mills, rolling cassettes, Turk heads, universal rolling mills, and precision rollers. We have independently developed a variety of advanced rolling technologies, such as rectangular spring wire rolling mills, flat wire rolling mills, volute spiral spring continuous rolling lines, valve spring rolling mills, and triangular wire rolling mills, designed to replace traditional European, American, and Japanese cold rolling mills.

Through our innovative approach, combining self-made cold rolling mills with drawing rolling dies, we provide a cost-effective solution for improving the quality of your products. This method ensures superior evenness, finishing, and straightness (up to 0.5mm/m), with thickness and width tolerances as precise as 0.005mm. Additionally, we have adopted advanced Japanese small high-precision roll processing and grinding technologies, achieving roundness tolerances of less than 0.001mm and finishing levels of 0.02μm
