提高中間包連澆爐數(shù)的生產(chǎn)實踐

打開文本圖片集

摘 要：中間包包襯壽命和連澆爐數(shù)是衡量連鑄機生產(chǎn)能力的一項重要經(jīng)濟技術指標，通過提高中間包包襯壽命與連澆爐數(shù)，不僅可以穩(wěn)定煉鋼工序生產(chǎn)節(jié)奏，有效提高連鑄機作業(yè)率，減少中包更換次數(shù)，還可以降低耐材成本和爐前出鋼溫度，提高金屬收得率。

關鍵詞：中間包；連澆爐數(shù)；生產(chǎn)實踐

Abstract：The ladle life and the number of continuous pouring furnaces is an important economic and technical index to measure the production capacity of the continuous casting machine. By improving the ladle life and the number of continuous pouring furnaces， not only can the production rhythm of the steelmaking process be stabilised， the operation rate of the continuous casting machine be effectively improved and the number of ladle changes be reduced， but also the cost of resistant materials and the temperature of the steel output before the furnace can be reduced and the metal yield can be improved.

Key words：intermediate ladle; number of continuous pouring furnaces; production practice

陽春新鋼鐵有限責任公司煉鋼廠擁有五機五流小方坯連鑄機3臺，主要生產(chǎn)HRB400E，HRB500E，HPB300，XGL等鋼種，普碳鋼最高拉速5.7 m/min、工作拉速4.0～4.8 m/min，因中間包壽命普遍不高，導致金屬收得率低、能耗高，大大增加了煉鋼工序成本和員工勞動強度。（剩余3270字）
