Excerpt: ...high heat during the period the alloy required to impregnate the metal, and the consequence was that, more often than otherwise, iron after being treated in the ladle was either poured too soon or was poured cold. And in the case of treatment in the cupola, the alloy too frequently was lost in the slag and passed off without reaching the metal. Between these two handicaps, Professor Stoughton admitted that titanium had had a hard time of it; but he submitted data from tests to support his contention that, if the metal in the ladle were sufficiently hot to stand three minutes or more and still pour at the ideal pouring temperature, and if the alloy can be charged when the bath in the cupola is free from slag, the effect will be notably better mental in both instances. The speaker submitted his opinion--with apologies--that in Mr. Gale's tests, detailed above, the metal generally had been teemed too cold. DISCUSSION. There was a vigorous discussion of Prof. Stoughton's paper, the tone of which again demonstrated a certain hostility toward the titanium propaganda. Thomas D. West, of Cleveland, recalled the unsatisfactory character of tests he had made with titanium on car wheel iron a year ago, in which the results varied discouragingly, without apparent reason. W. A. Bole, of the Westinghouse Foundries, recalled tests that had been made at the Trafford City shops some time since. "We found, in using our usual stock," said the speaker, "that the difference in the strength of the treated iron and the untreated iron was negligible. Our tests seemed to indicate that if the iron were good, originally, the alloy added no virtue to it. But when we In this paper an attempt will be made to describe the advancement in the different...
