I. Introduction

1.1 Industrial Positioning of Aluminum Ingot Production Lines

Within the non-ferrous metal processing industry system, aluminum ingot production lines serve as a critical hub for aluminum resource recycling and deep processing, connecting the entire workflow from scrap aluminum recovery, melting treatment, to finished ingot output. Whether recycling industrial scrap aluminum or casting primary aluminum, these lines undertake the core task of transforming fragmented aluminum raw materials into standardized aluminum ingots. They supply qualified billets for subsequent deep processing stages like rolling and extrusion, serving as vital support for the green circular development of the non-ferrous metals industry.

1.2 The Importance of Efficient Automated Casting Systems

As the non-ferrous metals industry transitions toward large-scale, green, and intelligent manufacturing, traditional manual or semi-automated casting models can no longer meet industrial upgrading demands. High-efficiency automated aluminum ingot casting systems not only significantly boost casting productivity and ensure dimensional accuracy and quality consistency, but also mitigate safety risks associated with manual intervention. They reduce energy consumption and material wastage, aligning with modern manufacturing principles of cost reduction, efficiency enhancement, and low-carbon development. These systems have become critical equipment for aluminum processors seeking to elevate their core competitiveness.

II. Overall Overview of Aluminum Ingot Production Lines

2.1 Core Functions

The core function of an aluminum ingot production line is to achieve the melting, quantitative pouring, forming, cooling, and finished product output of aluminum and other non-ferrous metals. Through standardized processes, it transforms liquid aluminum into uniformly sized aluminum ingots. Its core advantage lies in simultaneously supporting primary aluminum casting and recycled aluminum recovery. It processes various aluminum scrap materials (such as scrap aluminum profiles, scrap aluminum products, aluminum chips, etc.), refining them through melting before casting into ingots, thereby enabling the circular utilization of aluminum resources.

2.2 Application Scope

This production line is widely applied in the non-ferrous metal processing industry, serving scenarios such as aluminum smelters, scrap aluminum recycling enterprises, and aluminum deep-processing bases. It produces various industrial aluminum ingots and casting billets, meeting the processing requirements for subsequent products like aluminum plates, tubes, and profiles. It also supports small-scale ingot production for other non-ferrous metals like copper and zinc, demonstrating strong versatility.

III. Structural Design and Layout Features

3.1 Overall Layout Design

The aluminum ingot production line adopts a linear layout structure, forming an elongated configuration that aligns with workshop assembly line planning. Installation positions can be flexibly adjusted based on workshop space dimensions, balancing production continuity with spatial utilization. The core advantage of linear layout is achieving unidirectional material flow from pouring to forming and output, minimizing material handling between processes and enhancing production efficiency.

3.2 Core Component Configuration

The production line's core components include the head frame, tail frame, intermediate frame, pouring frame, and guide rails. These components collaborate to complete the entire ingot casting process:

• The head frame drives the conveying mechanism, providing power support for the production line.
• The tail frame guides and outputs finished aluminum ingots, connecting to subsequent stacking processes.
• The intermediate frame supports and conveys the casting mold, ensuring its stable operation.
• The pouring frame enables precise metered pouring of molten aluminum, controlling flow rate and speed accurately.
• The guide rails provide directional guidance for mold conveyance, guaranteeing precise trajectory.

3.3 Structural Material Characteristics

All components are fabricated from heavy-duty welded steel structures formed through precision welding processes. They exhibit high strength and stability, capable of withstanding high-temperature impacts during liquid aluminum pouring and vibrations during equipment operation. This effectively prevents structural deformation and extends equipment service life. Additionally, the steel surfaces undergo anti-corrosion and high-temperature resistant treatments, adapting to workshop environments characterized by high temperatures and high dust levels.

4.1 Ingot Production Parameters

The aluminum ingot production line demonstrates robust large-scale manufacturing capability, achieving a maximum ingot output of 8 tons per hour. Production capacity can be flexibly adjusted to meet diverse scenarios, from small-batch trial runs to high-volume mass production. For standardized aluminum ingot manufacturing, the line enables continuous, uninterrupted operation with stable, controllable daily output, fulfilling enterprises' large-scale production requirements.

4.2 Efficiency Enhancement Performance

Compared to traditional casting equipment, this production line significantly improves operational stability through optimized structural design and automated control. This effectively reduces equipment downtime for maintenance, boosting overall output efficiency by 20%–30%. Additionally, automated pouring and forming processes eliminate redundant manual operations, shortening the production cycle per aluminum ingot and further enhancing overall production efficiency.

V. Drive System and Speed Control

5.1 Drive Motor Configuration

The production line employs AC variable-speed drive motors as its power source. These motors feature high power output, low energy consumption, and stable operation, meeting the demands of high-load continuous operation. They also provide excellent speed regulation performance, forming the foundation for precise speed control.

5.2 Speed Regulation Method Selection

Two mainstream methods—electromagnetic speed regulation and variable frequency speed regulation—are employed, adaptable to production scenarios and precision requirements:

• Electromagnetic speed regulation offers simple structure and easy maintenance.
• Variable frequency speed regulation (VFD) provides a wide speed range, low energy consumption, and precise control.

5.3 Core Value of Stepless Speed Regulation

Stepless speed control enables precise synchronization between mold conveying speed and pouring speed. By dynamically adjusting operational parameters based on liquid aluminum flow characteristics and ingot specifications, it prevents issues like pouring overflow and uneven solidification, ensuring dimensional accuracy and surface quality of aluminum ingots.
