水平连铸工艺具有效率高、能耗低和质量好等优点,但在生产过程中,由于其涉及范围广、影响因素复杂多变,尤其高牌号铜合金,具有比重大,流动性好等特点,因此在操作经验不足,工艺参数掌握不当的情况下,时常会有“跑火”事故发生(即合金液从结晶器出口溢出,参见图1),造成严重的二次消耗浪费,为此对“跑火”事故加以严格控制和预防,并设置补救装置是颇有必要的。
Horizontal continuous casting process with high efficiency, low energy consumption and good quality, but in the production process, due to its wide range of involved, complex and volatile factors, especially high grade copper alloy, with a large proportion, good liquidity and other characteristics , So in the lack of operational experience, process parameters are not properly mastered, there will often be “running fire” accident occurred (ie alloy liquid overflow from the exit of the mold, see Figure 1), resulting in serious waste of secondary consumption, “Running fire” accidents to be strictly controlled and prevented, and set up remedial devices is necessary.
