Title:
鋳鉄に添加する構造改良剤の所要量を決定する方法、そのための設備およびコンピュータープログラム製品
Document Type and Number:
Japanese Patent JP4298925
Kind Code:
B2
Abstract:
The present invention provides a possibility to evaluate cooling curves recorded in near-eutectic cast iron melts. The curves are evaluated by generated in the melt in the center of the sample to the melt as a function of time. This information is then used to identify the part of the centrally recorded cooling curve that can be used as a basis for determining the amount of structure-modifying agent that must be added to produce compacted graphite cast iron, and/or spheroidal graphite cast iron, and to identify the part of said curve that is associated with formation of primary austenite.
