Show Wrought Iron From Ore. Wrought iron is not commonly produced pro-duced direct from the ore, but a Call-i fornla metallurgist, using petroleum ' as fuel, claims to avoid the usual trou-' bles and to obtain pure iron at a much I l educed cost. The ore, after grinding j to pass through a sixteen mesh sieve, Is mixed with some heavy oil, such aS asphaltum. The mixture is made into cylinders, each of a size to yield about 150 pounds of reduced iron, and these-cylinders these-cylinders are plnced In the furnace 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 reoxidation the great difficulty diffi-culty in previous processes a reducing reduc-ing atmosphere is maintained in the furnace, and the bloom i; compressed before entirely removing from the furnace. fur-nace. The time required for heating through and reducing is given as four or live hours.-- |
