CISDI’s second techno breakthrough for Ansteel

After its first breakthrough in ultra-deep-drawing production technology for automobile sheet, CISDI has now achieved another - galvaluminizing production technology for household appliances sheet.

CISDI’s achievement came during the rebuild of a continuous annealing furnace for Ansteel’s galvaluminizing line, which produces sheeting for household appliances.

The rebuild has taken 40 days, matching the build record for similar projects in China.

Features include an advanced non-oxidizing annealing furnace and safety interlock, a unique cooling roller, stably-performing post-plating cooler and air-mist cooling section.

CISDI’s subsidiary, the Thermal and Environmental Engineering Co., built the Ansteel O4-grade automobile sheet unit. The products are proving popular in China’s high-end market.

CISDI Thermal’s expertise in galvaluminized sheet has also been applied at Siemens and LG household appliances.

The Ansteel projects have resulted in CISDI being awarded two patents for non-oxidizing annealing furnace proprietary technologies.
