高炉鼓风不论采用那种方法,都应检测鼓风湿度并保持其稳定,因为大气湿度在冬夏和昼夜之间约在2～20克/标米~3间变动,这种变化会明显地干扰高炉的“热量管理”。湿度每变化10克/标米~3约需要32大卡的热量,这意味着炉膛中熔化温度变动100℃～180℃。显然,这种温度变化必然妨碍高炉熔炼过程的均衡,因而出现加湿或脱湿调剂。目前世界上技术先进的高炉一般都有湿度自动调节系统。而我国一些厂现仍使用苏制ДВ-264型干湿球湿度传送器,这种温度传送器有一系列缺点:精确度低于±5％,滞后性很大,润湿纱布会很快落上灰尘而使仪表指示值发生偏差,由于这种偏差常常觉察不出,而使调节给定值不真实。润湿纱布最 Blast Blast Regardless of the method used, the breeze humidity should be tested and maintained stable as the atmospheric humidity varies between 2 and 20 g / m 3 in winter and summer and between day and night, and this change significantly disrupts Blast furnace “thermal management.” Humidity per change of 10 grams / standard meter ~ 3 requires about 32 calories, which means that the furnace melting temperature change 100 ℃ ~ 180 ℃. Obviously, this temperature change will inevitably hinder the balance of the blast furnace smelting process, thus appear humidification or dehydration swap. At present, technologically advanced blast furnaces in the world generally have an automatic humidity regulation system. Some factories in our country are still using the Soviet-made ДВ-264 wet and dry bulb humidity transmitter, this temperature transmitter has a series of shortcomings: less than ± 5% accuracy, high hysteresis, wet gauze will soon fall Dust and instrumentation instructions deviate due to this deviation often can not be perceived, leaving the adjustment of the given value is not true.
