A pear-shaped steel shell lined with a refractory material containing a number of holes or ports in the bottom or side through which air is blown through the molten pig iron charge. The converter is mounted on trunnions about which it may be tilted to charge or tap. Molten pig iron is charged into the converter, and air is blown through the molten metal to oxidize the impurities, thus making steel. Henderson
