Abstract
Description
(1)循環移動するパレット上に鉄鉱石と炭材を含む焼結原料を装入して装入層を形成し、形成した装入層の炭材に点火炉で点火し、前記パレットの下方に配設したウインドボックスで空気を吸引することにより、焼結鉱を製造する焼結鉱の製造方法であって、
前記装入層を焼結する際に、酸素と空気と液体燃料とを、前記空気の酸素富化率を4〜10体積%にし、前記液体燃料の粒径を前記液体燃料用スプレーノズルで100μm以下に微粒化して、前記装入層の上部から供給することを特徴とする焼結鉱の製造方法。
(2)前記酸素は、前記液体燃料用スプレーノズルの上部に設置された酸素ノズルから供給されることを特徴とする(1)に記載の焼結鉱の製造方法。
(3)前記液体燃料用スプレーノズルに2流体型のスプレーノズルを用いて、前記液体燃料と前記酸素とを同時に噴射することを特徴とする(1)に記載の焼結鉱の製造方法。
