may make the i-efining step difficult, particularly in preventing

sufficient desulfurisation.

Theoretically, the Kjellin furnace construction provides the

most favorable utilisation of the electrical energy, this utilisation

being apparently more favorable than with an arc furnace. This

advantage is more than counterbalanced by the great j)hase dis-

placement, leakage and radiation losses, arising on account of the

annular arrangement of the furnace. A further disadvantage is

that it is always necessary to leave a portion of the charge in the

: furnace, in order to have a closed circuit for the induced current.

j As a result the quantity of the charge is not accurate, and also, all

additions of ferronmanganese have been unnecessarily made as

regards the remainder of the charge. From what I know of the

furnace it is very serviceable as a re-melting furnace. However,

as I stated at the beginning, I must leave further statements con-

cerning this 1078 furnace to better informed gentlemen whose

knowledge thereof is derived from personal observation during

operation.
