欧州における焼結鉱製造の新技術について

New Technique Applied for Sintering Process in Europe 満岡 正彦(Masahiko Mitsuoka) 要旨 : 高炉の大型化と焼結鉱配合比の増大化の傾向につれて,高炉操業におよぼす焼結鉱品質の 影響はますます顕著となってきている。諸外国においても焼結鉱の品質改善,安定化の研究 がさかんに行なわれているが,この報告では,最近の欧州における焼結鉱製造の新技術と, その成果について報告する。この報告で,紹介した新技術は,下記のとおりである。(1) 焼結鉱の化学的性質(主として Fe2O3)を測定して焼結鉱品質を測定する方法(2)焼結 混合原料通気度の連続測定(3)混合原料中の水分の測定方法(4)焼結層表面の着火状況 の監視(5)混合原料用注水を磁場にかける試験(6)適正操業曲線(7)返鉱による自働 制御(8)耐粉砕性シュート(9)焼結鉱の再加熱 Synopsis :

The quality of sinter has a remarkable effect on the operation of blast furnaces, along with the recent tendency that inner volume gets larger and sinter ratio within the blast furnace charge becomes greater. In foreign countries many researches have been made on improvement and stabilization of sinter quality. In this report recent results of new technique applied for sintering process in Europe are described, covering such articles as follows: (1) Determination of sinter quality by the measurement of chemical properties, (2) Continuous measurement of the permeability of sinter mix. (3) Measurement of the moisture content of sinter mix. (4) Regulation of the ignition condition of the surface of sinter bed. (5) Effect on sintering of water subjected to the magnetic field. (6) Optimum curve for sintering. (7) Automatic control by the return fines. (8) Anti-degradation chute. (9) Heat treatment of sinter.
