Page 135 - ... Some 90 tons of magnetite were used to demonstrate the feasibility of making pig iron and steel direct by the electric process. The furnace employed for these experiments is that used in making ferro-alloys. It is of the resistance type, and consists of two iron casings, forming shafts, communicating at their lower ends by means of a lateral canal. The casings are lined with refractory material, and the base of each shaft is provided with a carbon block, in electric communication with the exterior...
Page 68 - The Dominion Government at Ottawa and each province, at its city of chief importance, should have a museum belonging to and supported by the people. These museums should contain exhibits of the metallic and non-metallic minerals of the country, both those of economic and of merely scientific value, the forest trees, with the bark preserved, in, say, six feet sections, cut also and partly polished, and each specimen accompanied by a small map showing its habitat ; the fresh water and...

Page 132 - These drums serve the purpose of absorbing by water circulation through them the heat generated and of giving motion to the ore toward the gap. The parts of the drums to which the working current is distributed, and which form the electrodes, are armed with carbon plates. This current was furnished by two Brush Direct Current Generators, joined in series, of 50 volts and 3,000 amperes capacity each, thus giving 100 volts and 3,000 amperes.
Page 68 - ... evidences of the races we have supplanted in Canada, and much more that does not occur to me at the moment. I should not like to suggest a limit of expenditure on such museums. The necessity of a new building at Ottawa is admitted. The crime of leaving exposed to fire, in a wretched building never intended to protect anything of value, the precious results of over fifty years of collecting, has been pointed out in a recent official report.

Page 147 - ... narrow air gap left between the slag and the electrodes. The cost of the furnace and machinery to work the electrodes and bath is ^2,000. The electrodes are made of gas coke. The absorption of energy per ton of steel amounted to 0-153 EHP year. The Stassano furnace, used at Turin, is of a rotating type, and consists of a cylindrical outer casing of iron surmounted by a conical roof. It is lined with magnesite bricks. A three-phase alternating current of 90 volts between the phases and 400 amperes...
