Aluminum Production with the WDL-ZDJ-6 Fully-Automatic Casting Line

In the competitive landscape of industrial aluminum production, achieving a seamless transition from molten metal to finished product is paramount for efficiency and profitability. The WDL-ZDJ-6 fully automatic aluminum ingot casting machine represents a technological leap, specifically engineered for the high-volume production of standardized 6.5kg aluminum ingots. This machine exemplifies advanced aluminum casting automation, integrating a unique mechanical hammer-type demoulding system with energy-efficient operation to meet the demands of 24-hour continuous production cycles. This article provides a detailed overview of its operation, technical specifications, and the distinct advantages it offers to modern foundries.

Core Operation and Technological Process

The casting process begins when molten aluminum is channeled into a heat-resistant cast iron distributor on the machine. A key to achieving uniform ingot quality is the distributor's synchronous movement with the machine's chain speed . Its eight precisely aligned outlets ensure a continuous, laminar flow of metal into each ingot mold, which is critical for minimizing turbidity and oxidation. Operators synchronize the flow rate with the conveyor speed, maintaining the molten aluminum at approximately 85% of the mold's cavity depth to ensure consistency. The ingot mold, crafted from durable QT450 nodular cast iron, is pre-heated to at least 60°C via a manual ignition baking system to prevent thermal shock and ensure optimal solidification.

Following the pouring stage, the ingots move through an indirect spray cooling system. The core of the automation is the mechanical hammer-type demoulding system. Unlike manual methods, this mechanism delivers precise, consistent strikes to the molds, ensuring a demoulding rate of 99% or higher. This method significantly enhances operational safety, reduces labor intensity, and protects the molds from damage, contributing to a longer service life .

Engineering for Durability and Efficiency

The machine's construction prioritizes longevity and stability. The frame is built from high-strength rectangular steel tubes, providing a rigid foundation that resists deformation under continuous operation. The power transmission system, which utilizes a cycloid pinwheel reducer and frequency conversion speed control, requires only a 3.0 KW drive motor, making it exceptionally energy-efficient . The frequency converter allows for precise, stepless adjustment of the production line speed, which is directly displayed on the control panel for easy monitoring. The electrical control system employs components from internationally recognized brands like Schneider and Mitsubishi, ensuring high reliability and a low total cost of ownership.
