Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ...Cleveland, Ohio Dr. Mathews' paper covers the subject very thoroughly and leaves very little for discussion. One cannot but be impressed with the rapid growth in the production of steel in the electric furnace, when one considers the development that has taken place in less than sixteen years with the capacity of furnaces installed and building of over 1,000,000 tons per year. We are acquainted with large figures these days, but we must not forget that the first million is by far the most difficult to acquire. In my judgment the next period of sixteen years will show a much greater rate of progress than the past. In-1912 The National Malleable Castings Company installed a six-ton Heroult furnace at its Sharon Works for the production of a special steel, and during the past few months a second furnace of the same type has been added. The electric furnace was found to be much better adapted for this purpose than the open-hearth. Dr. Mathews mentioned the melting of pig-iron for malleable iron purposes. This use of the electric furnace is yet in its infancy. There has been some experimenting along this line with gratifying results thus far, and I look for considerable development in the near future, not only in the manufacture of malleable iron but also in the manufacture of iron castings, such as chill rolls, car wheels, etc., where uniformity and exacting analysis are required. Not only has the electric furnace come at an opportune time to take care of the automobile and aeroplane industry, as referred to, but it will set higher standards of quality which will spur the ingenuity of the steel maker to improve the quality.of Bessemer and open-hearth materials, and thus the electric furnace should be heralded as a beneficent acquisition...show more
