內容簡介

本書圍繞不同噸位與結構的鍊鋼爐冶鍊任務需求，通過理論計算、數值模擬分析、高溫噴吹實驗、水力學模擬等研究手段，深入探究了超聲速氧槍結構模式及噴吹方法對鍊鋼爐內多相熔池的流場分佈狀態的影響特點。並基於工業試驗與應用結果，對實驗室研究結果進行生產驗證，以確定適用於不同鍊鋼工況的超聲速供氧方法。系統對比了轉爐傳統氧槍、旋流氧槍、二次燃燒氧槍及預熱氧槍等多類別氧槍結構模式下的超聲速供氧效能、深入討論了電弧爐用常規集束供氧模式、氫燃集束供氧、變熱值集束供氧及超聲速環縫式供氧等不同伴隨熱能量流輸送方法下主氧射流的冶金技術指標，並總結了多種拉瓦爾噴管結構參數的設計與優化方法，為鍊鋼過程的超聲速供氧技術的深入推廣與高效應用提供了可靠的數據基礎與理論支撐。
