Worldsteel first Twitter debate - Steel: The Next Hero - Looking to the future
World steel announced its first Twitter debate - Steel: The Next Hero - Looking to the future.
The discussion is scheduled at 14:00 GMT for an hour on January 18th 2013.
This coincides with the launch of The white book of steel, a worldsteel publication that celebrates the history of steel and the steel industry. But worldsteel is looking to the future - the steel industry of tomorrow needs more ground breaking innovations such as the Bessemer process by English inventor and industrialist Sir Henry Bessemer which revolutionised steel production and changed the world.
A high-profile panel of respected and influential figures in the industry will be answering questions live on Twitter on:
1. Why is steel so vital to the world and you? The exciting opportunities that a career in steel provides.
2. The challenges and opportunities the industry faces as we look to find the 'next Bessemer'.
