冲天炉虽然具有2000年的漫长历史,但实现高度机械化、为了安全而采用水冷式近代熔炉却是近20多年来的事。今天,五十年以上的熔化工部无一例外地用手工破碎大块生铁、人工推料车、工人冒着风雨严寒、酷暑炎热、粉尘火花来加料;被堵出铁孔时喷出的火花烧伤;在灼热的炉中每天要坚持修炉数小时,他们可称得上是勇士。现在人们正以旺盛的活力进入长寿社会,因而最近跨入了在有空调设备的控制室内用按扭操作的时代,劳动歌己经变得不能理解。而且有趣的是黑烟监视灯(SL)突然增加。近十年来节能技术的进步取得了很大成果,冲天炉复兴(Tevivai)、复苏(Come back)、新生(renaissence)等的报导非常多见。
Although the cupola has a long history of 2000 years, it has been a matter of nearly 20 years to achieve a highly mechanized and water-cooled modern furnace for safety. Today, more than 50 years of melting ministry without exception by hand to break large chunks of iron, artificial pusher car, workers braved the wind and rain, hot summer heat, dust sparks to add material; Burn; in the hot stove every day to insist on repair stove hours, they can be called a warrior. Now that people are entering the longevity society with exuberant energy, they recently stepped into the era of button-operated operation in the control room with air-conditioning equipment, and their working songs have become incomprehensible. And it is interesting that the smoke monitor light (SL) suddenly increases. Recent advances in energy-saving technologies have yielded great results. Tevivai, Come back, renaissence, etc. are very common.
