In November 2011, the Fourth Steel Rolling Plant of the Maanshan Iron and Steel Company purchased our products covering 2 sets of YTD-II slag dart dispatching machine as well as the Φ250mm and Φ270mm slag darts for 300t converter. It took usage of the pneumatic slag stopping device manufactured by VAI Company originally. The slag stopping efficiency was only 90%, which affected the normal production of the fine steel. After the replacement by adopting our products, the cost for steelmaking is reduced and the slag stopping efficiency is raised to more than 97%.
Our products are fully affirmed by the Fourth Seel Rolling Plant. The factory promotes the application of our products to all the converters in the company.
