From the soaking pit it is taken to the mill and given seven passes through t h e blooming rolls by which it is reduced to a section 9% inches The molten cast iron from the blast furnaces is brought in ladles to two 150-ton iron receptacles and mixed to bring the metal to an even temperature for treatment in the converters.
