A continuous casting machine is a critical industrial equipment used in non-ferrous metal production facilities to transform molten metals like aluminum, copper, zinc, and lead into continuous strands, billets, or slabs. This machine enables high-volume production with consistent cross-sectional dimensions and improved metallurgical properties compared to traditional batch casting methods. It serves as a key link between smelting operations and downstream rolling or extrusion processes in B2B metal manufacturing supply chains. The equipment reduces material waste, energy consumption, and labor requirements while increasing production throughput for metal producers. The machine typically consists of a tundish, a water-cooled mold, secondary cooling zones, withdrawal rolls, and a cutting torch. Molten metal is poured into the mold where it solidifies at the surface, forming a shell, and is then continuously withdrawn through the secondary cooling zones to complete solidification before being cut to length. The cross-section dimensions can range from 100×100 mm to 300×300 mm, with casting speeds between 0.5 and 2.0 m/min. Cooling water flow rates are typically 80–150 m³/h, and the mold length is 500–800 mm. The machine operates at casting temperatures of 650–950 °C, depending on the metal (aluminum, copper, zinc alloys). Mold oscillation frequency is adjustable between 60 and 200 min⁻¹ to improve surface quality. The machine requires a three-phase electrical supply of 380–480 V AC (50/60 Hz) and consumes 45–90 kW of power. The operating pressure for hydraulic systems is 1.0–1.6 MPa, and the cooling water inlet temperature should be 20–35 °C. The machine footprint is 20–35 m², and its weight is approximately 15–25 t. Tolerances on cross-section for aluminum billets are ±0.5–±1.0 mm, per GB/T 1196. All values are reference ranges and must be verified with the manufacturer for specific models and applications. The machine is constructed with high-temperature steel alloys, copper mold plates, refractory lining, and a stainless steel frame. It is essential to confirm model-specific parameters and compliance with applicable standards before procurement.
Molten metal is poured into a water-cooled mold where it solidifies at the surface, forming a solid shell. The strand is continuously withdrawn through secondary cooling zones, where water sprays complete solidification. The solidified strand is then cut to length by a torch or shear. The mold oscillates to prevent sticking and improve surface quality. The process is continuous, allowing high production rates with consistent cross-section.
