ジャーナル フリーFounding practice in high atmospheric humidity as in Japan is rather difficult to produce sound castings due to blowholes. Especially in a large scale casting, the removal of moisture from a sand mold just before metal pouring is very important, because of its tendency to appearing defects of blowholes in the casting caused by keeping in high atmospheric humidity for a long time. With a view to preventing from arising these blowholes in the casting, many types of hot blast oven had been constructed in many foundries. The author, however, had constructed several other types of oven referring to these hot blast ovens and had given some improvements to them. Consequently, an electric resistance type hot blast oven having the simple construction and the easier handling have been obtained as followings. (N. T.)抄録全体を表示PDF形式でダウンロード (772K) -

ジャーナル フリーIn order to get acid resistant quality for cast iron, addition of various kinds of elements such as Ni, Cr, Mo and Si is considerable. In this report we state only a research of acid resistant cast iron of Si system. This report refers to the effect regarding between variation of Si and C% and melting, casting, cutting faculty, mechanical strength and acid resistant quality. As a result, we found within 5∼6% Si alloy has good quality against cutting and mechanical strength. Range of possibility of cutting faculty is within 13% Si: Over 12% Si is superior in acid resistant quality and over 14% Si is best. From these results, we consider acid resistant cast iron including 14, 12 and 5% Si is practical, then we are going to study about these 3 alloys precisely in the following period.抄録全体を表示PDF形式でダウンロード (808K) -
