IO THE HAMILTON ASSOCIATION. 
MARCH 13th, 1902. 
On invitation, our members attended a meeting of the Canadian 
Association of Stationary Engineers, when a paper was read on 
“The Manufacture of Iron,” by Mr. C. Fox, Chemist and Superin- 
tendent of the Hamilton Blast Furnace. 
Tron ore consists of iron plus oxygen in chemical union. The 
O. is taken away by means of C. O. gas. This gas is always pro- 
duced when there is an excess of fuel and a deficiency of air. In 
the H. B. F. 3,000,000 gallons of water a day are used for 
cooling purposes. A section of one of the stoves was shown 
and explained. From it air at a temperature of 1400° is blown into 
the Furnace. This in contact with white-hot coke makes a most 
intense heat. By means of a diagram the parts and working ofa 
furnace were fully explained. In the H. B. F. 300 tons a day are 
produced. For each ton 5.8 tons of air and 3.1 tons of coke, ore 
and limestone are used. About 30,000 cubic feet of air a minute is 
blown into the furnace by a force of 2000 horse power. About 3000 
tons of gas goes out of the chimney in 24 hours, and by means of 
piping this is taken down to the stoves and used for fuel. The use 
of limestone was explained. The chief impurity in ore is Silica. 
This unites with the limestone to form a fusible slag. The various 
classes of pig iron were described.

lecture proved extremely interesting, and called forth a hearty vote 
of thanks.
