红旗二号简易炼焦炉原为人工扒焦,因此就必须在900℃的高温下进行露天操作。如扒焦顺利,一炉要15分钟左右;若焦饼收缩不好,炉温低时需延长至一小时左右。这样,冷空气进入炭化室过多,往往使炉温急剧下降,同时扒焦对炭化室振动太大,影响了炉体寿命,而且容易将大块焦捣碎,降低结焦率。我们曾到石家庄等厂参观见到使用的手摇推焦机很好,但据了解造价昂贵,人工推焦机需改装原建成炉子的炉门,加添炉柱、拉条,特别是对已投产的砖砌集气道和 The red coke oven II was originally a manual coke coke, so it must be open at 900 ℃ high temperature operation. Such as the smooth coke, a furnace to 15 minutes or so; if the coke cake contraction is not good, the temperature needs to be extended to an hour or so low. In this way, cold air into the coking chamber too much, often make the temperature dropped sharply, while the grill on the carbonization chamber vibration is too large, affecting the furnace life, and easy to block coke bulk, reduce coking rate. We visited Shijiazhuang and other factories to see the use of hand-cranked pusher is very good, but it is understood that the cost is expensive, the artificial pusher machine need to be converted to the original built furnace door, add furnace pillars, pull articles, especially for Put into operation brick and airway
