    The manufacturing method of the low phosphorus pig can be divided into two general classes;
    A. The products made by selecting the raw materials which are low in phosphorus, or dephosphorised preliminary by the dressing and etc. The charcoal pig, hematite pig and Peu-hsi-hu low phosphorus pig belong to this class.
    B. The products made by the manufacturing method diminishing any content of phosphorus in the pig irons regardless the raw materials. The Kenjiho low phosphorus pig which is produced by the patented process of the Kenjiho Iron Works, belongs to this class.
    In this paper the auther explained the construction and the working data of this refining process.

    Die Faser im Stahlmaterial ist einer Fehler im Stahl. Aber es ist verschieden mit der Gebrauchsrichtung des Materials und der Richtung des Auftretens der Faser. Das Aufreten der Faser ist unbedingt unvermeidlich in heutiger Fabrikationsweise des Stahles. Es gibt nur eine Mittel da nach einer Richtung, wo nötig ist, umznfuhren.
    Zuerst werden die Begriffserklärung, die Ursache und das Auftreten der Faser gesprochen und erklärt, dass die Erscheinung des Auftretens in die Art des Reineisens, das chemisch ganz einfach als der Spezialstahl ist, der chemisch sehr kompliziert ist, schwächer ist. In heutiger Zeit, in die Speziälstahle vorgezoger sind, kommt es vor, dass uber die Erscheinung viel gedacht werden soll.
    Dann die Beziehung zwischen dem Einfluss der Faser und den phisikalischen Eigenschaften des Stahles wird erklärt. Ueber deren Umführungsweise wird es gesagt, dass wenn der Stange die Spiralfaser gegeben wird, die phisikalischen Eigenschaften der Querrichtung der Stange höher als die Längsrichtung gebracht werden, und dass mit dem mannesmannisch gelochten Walzprodukte diesen Zweck wohl erreicht werden kann.
    Als die Verwaendung werden das Gewcher-Geschuetz-und Luftkammermaterial des Torpedos u.s.w. genannt.
    Ueber die Hauptpunkten der oben gesagten Erklärungen, werden die geprüften Ergebnisse gezeigt.
    In dieser weise Kommt der Redner zum Schluss:
    Wenn man zum Stangenmaterial die Spiralfaser gibt, kann man die phisikalischen Eigenschaften der Querrichtung höher als die Längsrichtung bringen.
    Diser Zweck kann mit dem mannesmannisch gelochten Walzen erreicht werden.

    From the results of the former experiment carried out by one of the writers, about 40 kinds of acid-resisting alloys such as nickel-base and iron base alloys were chosen and were studied to compare their resistivities against hydrochloric acid under following conditions; in 20 percent and 10 percent boiling condition, in 30 percent and 10 percent solutions both at room temperature. According to these experiments, the resistivities of Nemif C1, Nemicle C and Necomicle alloys are comparable with that of the Hastelloy A in 30 percent solution at room tempeiature and also in 20 percent boiling solution. The former alloys have, moreover, superior qualities than the latter, that they resist against the solution which contains an oxidizing agent for instance ferric chloride or others and they can also be easily cast and forged. The resistivity of Nemif CCL is also better than that of the Hastelloy A in 10 percent boiling solution and its qualities are similar to that of the latter. Nemicle, Nemicle C and Necomicle alloys are not only attacked by dilute hydrochloric acid such as 10 percent solution, but also by sulphuric and nitric acids, ferric chloride and mercuri cchloride solutions, while the Hastelloy A is attacked by these solutions. The resistivity of Nemicle F is also comparable with that of the Hastelloy A and its cost is half of the latter and can be more easily cast and forged and many kinds of modified alloys of this Nemicle F are also studied in acids, ferric chloride and mercuric chloride solutions. These nikel-base alloys as well as the iron-base alloys were newly prepared by the writers, the resistivities of the latter are not so good as those of the former, but they are merely comparable with that of pure electrolytic nickel in the experimental condition, and those alloys in general can easily be cast and forged. The appearance of the specimens of Nemicle, Nemicle C, Nemicle F, Necomicle, F1, F8 as well as those of famous alloys such as Hastelloy A, Nichrome, 188 chromium-nickel stainless steel, Duriron, Electrolytic iron and nickel attacked after 70 days by 10 percent hydrochloric, sulphuric and nitric acids are repectively shown in photographs.
