    • 超級鋼相關知識日新月異，為了達到更有效率的學習，一個架構清晰且使用方便的知識庫有其必要性。本研究以知識管理為出發點，針對超級鋼的超潔淨度、高均勻性和超細晶粒三大特性，蒐集並彙整相關冶煉製程及超級船板鋼的應用，建構一個超級鋼冶煉製程知識庫，並以網頁形式呈現此知識庫。
    本研究所建立之知識庫主要分成超級鋼冶煉製程和超級船板鋼應用兩大部分。首先將冶煉製程分為煉鋼和連鑄，並針對超級鋼的特性，將製程分成煉鋼－潔淨化、煉鋼－均勻性、煉鋼－超細晶、連鑄－潔淨化、連鑄－均勻性及連鑄－超細晶六大項目，其中煉鋼－潔淨化又分成去除雜質元素和夾雜物控制兩個項目，每個選項下方會根據其要求分述適合的製程。超級船板鋼應用則是分成超級船板鋼特點與分類、超級船板鋼條件要求、超級船板鋼冶煉製程和控軋控冷應用四大項目。其中超級船板鋼冶煉製程又分成化學成分設計、微合金化處理、有害元素控制、潔淨化控制和連鑄坯品質五個項目，每個項目都可再連結回超級鋼冶煉製程選單做交叉學習。
    本研究所建立之知識庫網站具有知識管理之價值，不僅能幫助超級鋼領域初學者瞭解超級鋼特性、冶煉製程及其應用，亦提供超級鋼進階人員一個實用的知識庫系統。而與其他的學習管道比較，本知識庫網站不僅便於增修、更新與擴充，更具備全文檢索功能，為一因應e世代潮流的知識取得管道。

    There are constantly new technologies and information generated in the field of super steel. In order to extract knowledge effectively, we need a knowledge-based system with a clear structure. There are three main characteristics of super steel, which are cleanliness, high homogeneity and ultrafine grains. On the basis of the above characteristics, a knowledge-based system for super steel metallurgical processes and the applications has been established from the standpoint of knowledge management and demonstrated in the form of web-sites.
    The knowledge-based system in this study is chiefly separated to two parts, which are super steel metallurgical processes and the applications of super ship plate steel. In the first part, the super steel metallurgical processes are classified into six categories based on the characteristics of super steel: steelmaking-cleanliness, steelmaking-homogeneity, steelmaking-ultrafine grain, continuous casting-cleanliness, continuous casting-homogeneity and continuous casting-ultrafine grain. Furthermore, the steelmaking-cleanliness is classified into removal of impurity elements and control of inclusions. Each item is further recounted in accordance with the different requirements. In the second parts, the applications of super ship plate steel are classified into four categories, which are characteristics and classification, requirements, metallurgical processes and controlled rolling-controlled cooling. Besides, the metallurgical processes of super ship plate steel are further divided into five categories, which are chemical constituents design, microalloying, deleterious elements control, cleanliness control and quality of continuous casting strand. Each class of metallurgical processes of super ship plate steel could be linked back to super steel metallurgical processes for cross-learning.
    The super steel knowledge-based system is valuable for knowledge management. It can help not only the beginners but also more experienced engineers in the field of super steel. Compare with other methods of knowledge acquisition, this knowledge-based system is easier to be modified and updated. In addition, it also has a Site-search function to enhance its value.
