The Iron and Steel Industry in China

One of the problems of China's steel industry is the lack of scrap to provide a suitable charge for open-hearths. Since China had been a small consumer of iron and steel in the past, the domestic supply of scrap is inadequate. Scrap shortage is remedied in two ways: (1) imports of scrap, (2) substitution of direct-iron and sponge-iron for scrap.One of the problems of China's steel industry is the lack of scrap to provide a suitable charge for open-hearths.
