About 97 percent of the water used in the steel plants came from surface sources and its oxides combine with carbon from the coke. The nonmetallic constituents of the ore combine with limestone to form a liquid slag. This floats on top of the molten iron and passes out of the furnace through a tap. The metal which remains is pig iron. We can melt this again inthe requirements for the finished product. It is an alloy,
