Production of Pig Iron Increases

The Hwanghae Iron and Steel Complex is bringing about an upsurge in production.

The complex saved a great deal of electricity, equipment and labour by making use of cooling water from the oxygen-blast furnace to remove slags.

It improved dust-collection efficiency by adapting dry dust collector of furnace into wet one.

Besides, it reduced the melting time per charge by fixing the amount of raw materials according to their features and ensuring the temperature and oxygen-blowing in a scientific way to boost pig iron production.
