Show Wrought Iron From Ore. Wrought Iron is not commonly produced pro-duced direct from the ore, but a Call-j fornla metallurgist, using petroleum as fuel, claims to avoid the usual troubles trou-bles and to obtain pure iron at a much I educed cost. The ore, after grinding tp pass through a sixteen mesh sieve, Is mixed with some heavy oil, such as asphnltum. The mixture !s made into cylinders, each of a size to yield about 150 pounds of reduced iron, and. these cylinders are placed In the furnnco and gradually heated to the welding point of the iron, then taken out and compressed into blooms. A little silicate sili-cate rock Is added to give slag enough to hold the semifluid mass together. To avoid reoxidatlon the great dlfll-culty dlfll-culty in previous processes a reducing reduc-ing atmosphere Is maintained In the furnace, and the bloom is compressed before entirely removing from the furnace. fur-nace. The time required for heating through and reducing is given as four or live hours. |
