Abstract
This article gives in details the description of the Rochling-Rodenhauser furnace of one ton capacity installed in Miike Works, Ohmnta.
In the first chapter short remarks are given on the theory, history and advantages of this type of furnace. From the second to the fourth chapter, it is spent on the question of design furnishing actual data covering the constrnction, electrical calculation and accessory machincries, and pointing out a few phases on which special care must be paid. It shows no general procedure for design, but an example of a furnace which is operating suc-cessfully with cold scrap. The fifth chapter briefly describes the practical operating method of the furnace. In the sixth chapter the anthor speaks from experience upon those problems, particular to this type of furnace, such as hearth lining, circulation of molten iron and pyroelectric characte-risthes of refractory material.
At final conclusion, it is stated this type of furnace is superior to arc furnace in many respects and is recommended for producing high grade steel from cold scrap at small scale, although the difficulty of obtaihing good hearth lining may hardly give favorable results at first to those who are non-expert with basic lining.
