Nirayama reverberatory furnace is located at lzunokuni-city of lzu-Peninsula, Shizuoka-Prefecture. Hagi reverberatory furnace exists at Hagi-city, Yamaguchi-Prefecture, but Nirayama's one is the only one architectures that could make cast iron cannon. There are still remained some unknown matters as follows ; (1) whether cast iron was really melted or not, (2) what kind of pig-iron was used, (3) whether blowing of bellows were utilized or not, (4) what kind of fuels were used, (5) where firebricks were made, etc. On this Nirayama reverberatory furnace, the possibility of casting of cannon with iron was investigated, with melting experiment from a foundry engineering standpoint.   The followings are presumed from the investigation. Firstly, at least three cannons of cast iron were manufactured. Secondly, high Silicon contained pig-iron could not be available, so casting of iron cannon was not well done. Finally, the melting time by reverberatory furnace, from preheating to pouring completion, was about eight hours and melting temperature was above 1623K.

Since cast iron is a compound material of steel and graphite, its mechanical properties change according to the amount, form and distribution of the graphite. In this paper, the effects of graphite on the mechanical properties were kept constant. That is, the eutectic graphitization ability (EGA) in gray cast iron was limited to approximately 50%, and in the case of spheroidal graphite cast iron, the nodularity was maintained above 80%.  This paper presents a method of determining the mechanical properties from the hardness. First, the relationship between hardness and tensile strength was established and then the relationship between tensile strength and various mechanical properties was determined. From the data thus obtained it was possible to determine the various mechanical properties only from the hardness.
