Calderys has successfully completed the industry's first full aluminum furnace relining using 100% Fast Dry (FD) and Steady Dry (SD) castable refractory technology on a 25-tonne melting furnace. The solution reduced furnace dry-out time by more than 50% compared with conventional methods, while eliminating explosive spalling and post-installation repairs. It also lowered burner operating time during commissioning, reducing energy consumption and CO₂ emissions. Following commissioning, the furnace resumed production quickly and has operated continuously without refractory-related issues. Calderys said the integrated refractory solution is designed to support 12-15 months of maintenance-free operation while improving reliability and reducing shutdown costs.

[SMM Aluminum Alloy Daily Review] SMM ADC12 price rose 100 yuan/mt from the previous day to 23,950 yuan/mt, with the market center moving further upward. The core driver behind the price increase remained the cost side, as aluminum scrap prices stayed high, tight supply of compliant raw materials and persistent tax invoice cost pressure kept enterprise production costs elevated. Although downstream demand was mediocre, with limited incremental orders, and downstream procurement was still mainly based on essential restocking, enterprises were more consistent in their willingness to hold prices firm amid strong cost support.
