A computer control system for cold rolling steel was recently registered as a trademark with the State Administration for Industry and Commerce, the first for China in the field, according to the trademark owner Angang Steel based in Anshan.

Trademark registration for the project, jointly organized by the company and Yanshan and Northeastern universities, shows foreign monopoly of control system technologies has been challenged, the company said.

The nation's first proprietary system to measure and control making of cold-rolled steel plates generated 24 patents - 14 for inventions and 10 for utility models, five software copyrights and two academic books.

Demand in the auto and home appliance sectors for high-quality cold-rolled plates has been mostly met through use of imported technologies.
