pig iron

The name for the melted iron produced in a blast furnace, containing a large quantity of carbon (above 1. 5%). Named long ago when molten iron was poured through a trench in the ground to flow into shallow earthen holes, the arrangement looked like newborn pigs suckling. The central channel became known as the “sow,” and the molds were “pigs. ”
