我厂4吨/时倒置大间距两排风口冲天炉,使用换热器已有十几年时间。热风炉胆的寿命和实用效果逐年提高。到目前为止,炉胆寿命达3年之久,熔化炉次在300次以上;热风温度稳定在180～200℃;与相同吨位冷风冲天炉相比,铁水温度高15～20℃,熔化速度快15～20％。但是,如果因炉胆结构设计不合理、安装维护不当,致使炉胆寿命太短,反而低贬了换热器的
I plant 4 tons / inverted large pitch two-row outlet Cupola, the use of heat exchangers have been more than 10 years. Hot air oven gallbladder life and practical results increased year by year. Up to now, the life of the furnace has reached 3 years, and the number of melting furnaces is over 300 times. The hot air temperature is stable at 180 to 200 ° C. Compared with the same tonnage cold air cupola, the molten iron temperature is 15 to 20 ° C and the melting speed is high 15 ~ 20%. However, if the furnace structure due to unreasonable design, improper installation and maintenance, resulting in the life of the furnace is too short, but low devaluation of the heat exchanger
