Excerpt: ... at the start. 0ne or two minutes more may be consumed in transferring the boat to the combustion tube and connecting L-J in the train. But 15 minutes are required to burn the sample and carry all of the C02 to L-J. In this way perfectly accurate combustions of all kinds of steels, either plain or alloyed, with any amount of tungsten, molybdenum or chromium can be carried through in 20 minutes. This is the routine practice in this laboratory when making bath tests of open hearth heats before same are ready for tapping. This furnace has one marked advantage over electrically heated furnaces, in that it can be brought from a cold state to 10000 C. in 10 minutes. It can also be adjusted to fit any size combustion tube. (See Fig. 12.) CHAPTER XI. Part III. FURTHER NOTE ON THE DETERMINATION OF CARBON IN STEEL AND FERRO-ALLOYS. Surface Decarbonization. Referring to remarks on page 218 relative to the taking of samples it must be noted that steel often has a decarbonized surface, that is from 10 per cent to almost any amount lower in carbon than the main body of the metal. This will often cause the chemist to report the rolled or hammered steel anywhere from 0.10 to 0.20 lower in carbon than the original ingot analysis, that is, suppose the ingot analysis was 1.20 per cent carbon then it not infrequently happens that the plate or bar may show but 1.10 per cent. Use Of Sand In Boats. The author no longer uses any sand in the combustion boat as the composite vitrified clay boat is greatly superior and withstands a much higher heat than the original form of clay boat. By avoiding extreme heats during the combustion, complete decarbonization can be effected without fusing the drillings to the boat, and the little pile of sintered oxide that remains after the burnin...

Book Description

Excerpt from Rapid Methods for the Chemical Analysis of Special Steels, Steel-Making, Alloys, and Graphite IN offering this little volume the author desires to call attention to the portions of it that he has worked out in his own way and that are, as far as he is aware, new features. (1) A qualitative test for titanium in the presence of vanadium. (2) The annealed test for ebro mium in steel. (3) The test for annealing in steel. (4) The pouring Of the indicator into the solution when titrating for vanadium and chromium in steel, in the presence of either or both elements. (5) The determina tion of small amounts of copper and nickel in steel and ferro-vanadium by first separating the copper and nickel from the bulk of the iron and vanadium by means of potassium ferricyanide. (6) The exact determination of phosphorus in ferro-vanadium, demonstrating that as little as one-eighth of the actual phosphorus may be Obtained by the ordinary processes. (7) The application of the new heating wire to a combustion tube. (8) The modified method for higher per cents of nickel. (9) The determination of Silicon carbide in old plumbago crucibles and its existence therein. (10) The automatic labora tory still. (11) The simple laboratory method for making clay combustion boats. (12) The method for annealing Hadfield's steel. (13) The author's method for the rapid volumetric determination Of manganese in the presence of iron, Calcium and magnesium, by means of potassium ferricyanide. (14) The new form of potash absorption and weighing apparatus for carbon dioxide. (15) The new form of combustion train.
