工业炉窑之各国的锻造炉节能技术一览

发布日期:2018-12-11 作者:威光节能 点击:

在轧钢、锻造等行业中,能源成本在产品成本中占有相当的比例如25%—35%,因此节能成为重要问题。在这类加热炉北京11选5中,在美国常用的节能技术也不外乎采用多种和多级换热设备回收烟气余热,精确控制温度,陶瓷纤维衬里,高辐射涂层,更换节能型烧嘴及空燃比自控等等。先进的技术有富氧烧钢,脉冲燃烧,计算机控制和综合优化技术等。从工艺角度看,有炉气控制,等温锻造,高速热锻,精密锻造(热模锻)等。

二、英国的锻造炉节能

 

锻造炉北京11选5是一种热效率不高的炉子的典型,重型锻造炉,能耗相当大,因此回收其烟气余热,意义很大。英国ForgemastersEngineering公司在重型锻造炉上米用了RCB和陶瓷纤维衬里两项改造措施后节能32%。证明余热回收,用低热容陶瓷纤维作衬里是锻造炉的两项基本的节能措施。其中RCB用于锻造炉包括落锤锻造加热炉非常合适。
