Homogenization furnace and integrated forced cooling system improving billet microstructure before extrusion. ±5°C uniformity guarantee.
Cast aluminium billet has a heterogeneous microstructure after VDC. Segregation, dendritic structure and undissolved phases lead to profile defects and die wear during extrusion. Homogenization heat treatment eliminates this heterogeneity, significantly improving billet quality and machinability.
GUMEN homogenization furnaces are delivered with a ±5°C uniformity-guaranteed heating profile and integrated forced cooling system. Batch or continuous configurations are available depending on capacity.
The value of the homogenization furnace lies not only in the heating step but also in the cooling profile. Slow cooling can lead to re-precipitation, while rapid cooling can cause cracking risk. GUMEN's integrated air or air-water forced cooling system provides the cooling rate optimised for each alloy. Forced cooling also offers a metallurgical advantage: the microstructural conditions necessary for the billet to deform more easily during extrusion are established.
±5°C uniformity across the billet cross-section is achieved with furnace air circulation and a controlled heating profile. Stable metal flow during extrusion.
After homogenization, the billet is cooled in a controlled manner with an integrated forced air or air-water cooling system. Optimum microstructure is achieved.
From VDC casting machine to extrusion heating furnace, operates integrated with GUMEN systems on the same PLC infrastructure.
Temperature-time profile is recorded for every charge. Data infrastructure ready for production tracking, quality reporting and process improvement.
