鑄物用銑製鍊時의 成分管理에 對한 考察 = The Control of Chemical Composition on Smelting of Foundry Pig Iron in Blast Furnace

국문 초록 (Abstract)

鑄物用銑을 決定지우는 가장 重要한 元素는 Si%이다. 普通 1.2% 以上의 Si含有量이 要求되고 있으나, 이 Si%이 管理는 高爐에서, 가장 어려운 問題이기도 하다. 三和製鐵株式會社에서 鑄物用銑製鍊時에 問題가 된 銑鐵中 Si%의 變動 및 그의 管理方法에 對하여, 實績을 土臺로 各種의 要因解析을 하였으므로 여기에 報告한다.

The silicon contents were the most important factor at determining the properties of the foundry pig iron in blast furnace. As a general rule, the silicon content was required of 1.2%.
However, in Blast furnace the control of silicon contents and these were the problem of most difficults. This is a report on the variations of the silicon contents and these contral methods on smelting in blast furnace of SAMWHA IRON & STEEL COMPANY. The most important factor affecting silicon contents is considered stable condition of furnace operation.
