Annike successfully won the bid for the general contracting project of 2 × 1080 blast furnace new hot blast stove project.
A few days ago, Zhengzhou Annike Industrial Co., Ltd. successively won the bid for Hebei Rongxin Iron and Steel Co., Ltd. and Hebei Xinda Iron and Steel Co., Ltd. to add hot blast stove general contracting projects.
Hebei Rongxin and Hebei Xinda Iron and Steel Co., Ltd. belong to Hebei Xinda Group, and the furnace capacity of both blast furnaces is 1080m.3, respectively equipped with 3 imitation Karujin hot blast stove. After 6 years of operation of the hot blast stove, the air temperature level gradually decreased from 1200 ℃ to 1150 ℃, and the fuel ratio continued to rise. The existing 3 hot blast stoves have been difficult to meet the requirements of blast furnace high temperature and high strength smelting.
The two blast furnaces each added a top-burning hot blast stove, hot blast stove using the rotary cutting top-burning hot blast stove burner jointly developed by MCC Jingcheng and Annike. Rotary cutting top-fired hot blast stove burner integrates the advantages of a variety of hot blast stoves at home and abroad, and through innovation, it has formed a series of core technologies with completely independent intellectual property rights. It has significant advantages in improving hot air temperature, extending the life of hot blast stove, energy saving and environmental protection, reducing floor space and investment.
After the completion of the new hot blast stove project, the existing 2 blast furnaces and 6 hot blast stoves will be repaired in turn on the premise that the blast furnaces will not stop production. All the repaired hot blast stoves will be equipped with rotary cutting top-burning hot blast stove burners. Finally, each blast furnace is equipped with 4 hot blast stoves, and the temperature of two fires and two air supply is more than 1250 under the premise of single blast furnace gas and double preheating of air gas.
