+86 13433279924The homogenizing furnace system heats aluminum billets to eliminate residual stress and enhance their properties. The cooling chamber ensures a fine grain structure, while the process reduces segregation and residual stress in semi-continuous casting.
The homogenizing furnace system consists of a homogenizing furnace, a cooling chamber, and a material cart. Through precise temperature control, the homogenizing furnace heats aluminum billets to the appropriate annealing temperature, homogenizing the casting structure and eliminating residual stress, thereby producing aluminum billets with superior properties.
The cooling chamber uses both cooling air and water to forcibly cool the homogenized aluminum billets, resulting in a fine and uniform grain structure.
In the semi-continuous casting process of aluminum alloys, the rapid cooling rate causes the alloy composition to solidify under non-equilibrium conditions, leading to segregation, reduced plasticity of the ingots, and poor processing performance, which adversely affects subsequent hot and cold processing. Additionally, during casting, the difference in cooling rates between the surface and the core creates thermal residual stresses, further impacting the hot and cold processing stages. The purpose of homogenization annealing is to heat the ingots to a specific temperature, enhancing atomic diffusion capability, thereby accelerating the transformation from a non-equilibrium to a balanced state, effectively eliminating structural and compositional segregation as well as residual stress.
Features
Precise Temperature Control: Enables the heating of aluminum billets to the exact annealing temperature for effective homogenization. Residual Stress Elimination: Homogenization effectively eliminates residual stress generated during the casting process.
Enhanced Aluminum Billet Performance: Post-homogenization, the aluminum billets exhibit superior performance characteristics. Promotion of Atomic Diffusion: The homogenization annealing process enhances atomic diffusion, accelerating the transition from a non-equilibrium to an equilibrium state.
Elimination of Structural and Compositional Segregation: Homogenization annealing eliminates structural and compositional segregation occurring during casting.
Improved Processing Performance: Homogenization improves the hot and cold processing performance of aluminum alloys.
Our tilting furnace and internally-guided hydraulic casting machine optimize molten aluminum control and safety, enhancing casting precision and reliability.
Our robotic palletizing system is a versatile solution used across various industries, including machinery, food, and chemicals. It is particularly effective in non-ferrous metal ingot production, such as aluminum and zinc, automating the process of grasping and palletizing ingots. This system reduces labor costs, enhances efficiency, saves space, and improves the production environment.
The machine includes a loading rack, saw table, pressing and length-cutting mechanisms, and an aluminum chip recovery system. It features hydraulically driven motions for stable and reliable performance, with an integrated hydraulic station and electrical control system.
This aluminum melting and recovery process uses a double-chamber structure, with an external melt pump transferring molten aluminum between the reflective furnace and the melting chamber. This design minimizes oxidation and ensures efficient sinking of aluminum chips, resulting in a high recovery rate, low cost, and reduced oxidation loss.
