[SMM Aluminum Flash News] Fosbel Promotes Ceramic Welding Technology for Online Aluminium Furnace Repairs

Published: Jun 25, 2026 10:03
Fosbel has highlighted its Ceramic Welding technology as a solution for repairing refractory linings in aluminum furnaces without requiring shutdowns. The process uses an exothermic reaction to fuse new refractory material directly onto existing linings while furnaces remain in operation at temperatures above 1300°F. The technology is suitable for 60%, 70% and 80% alumina refractories commonly used in aluminum furnace applications and is designed to repair worn areas such as metal lines, roofs and sidewalls. Fosbel said the technology can be used for both maintenance and preventive repair programs to extend furnace campaign life and reduce downtime. The company has also introduced Nano-Tec™ ceramic welding powders, thermal cleaning systems and Supertorch equipment to improve repair efficiency, reduce material loss and lower maintenance costs. Hot-repair technologies are increasingly being adopted by aluminum producers seeking higher furnace reliability and operational efficiency.

[SMM Aluminum Alloy Express] This week, social inventory of secondary aluminum alloy ingots in China fell by 2,800 mt WoW to 50,400 mt, marking the fourth consecutive week of destocking, with inventory levels pulling back further. Supply side, affected by tight supply of tax invoices, restricted procurement of compliant raw materials, and weakening end-use demand, operating rates of secondary aluminum enterprises continued to decline from June, and production release was somewhat suppressed, leading to a corresponding reduction in new warehouse inflows to social inventory. Demand side, the recent accelerating decline in aluminum alloy futures prices drove some downstream dip-buying and increased repurchase willingness among manufacturers, quickening the pace of warehouse withdrawals.

[SMM Aluminum Alloy Daily Review] Today, the SMM ADC12 price fell by 150 yuan/mt from the previous day to 23,850 yuan/mt. Amid the continuous price decline, the purchasing enthusiasm of downstream clients did not pick up significantly. Downstream players still mainly made just-in-time procurement, with a strong wait-and-see sentiment and insufficient restocking willingness. Meanwhile, aluminum scrap prices showed relative resilience. In particular, the supply of compliant raw materials remained tight. The price decline further squeezed the profits of aluminum scrap suppliers, leading to an intensified sentiment of holding back from selling and affecting raw material circulation to some extent.
