Huaigang Iron and Steel Plant 6# blast furnace successfully opened

Release time：May 13, 2019 From：ADMIN

In front of the 6# blast furnace of the ironmaking plant of Huaigang Special Steel Co., Ltd. of Jiangsu Shagang Group, a hot iron water flows into the main ditch, flows out of the skimmer and flows into the ladle. It marks the successful completion of the iron-making technical transformation project of the company – the 6# blast furnace overhaul project has been successfully completed and successfully opened!

　　The opening of the new blast furnace is related to whether the production, safety and technical indicators of the first generation can be operated in a long-term and benign manner. The importance is self-evident. At the opening of this furnace, the ironworks continued to use the self-developed automatic oxygen lance integrated application technology.

　　The 6# blast furnace was successfully ignited at 23:18 on April 12, and the molten iron flowed out smoothly at 4:46 in the morning on the 13th. At 7:00 on the 13th, the iron was discharged 4 times in front of the furnace, and the main ditch was realized for the 5th time. The skimmer smoothly passed the iron, and the whole process of opening the furnace took less than 12 hours to achieve safe, efficient, environmentally friendly and low-cost furnace opening.

　　In the process of opening the furnace, the automatic application technology of the automatic oxygen lance has played a huge role and once again shows a huge technical advantage. In the past, the new blast furnace was opened. The first time the iron was discharged was basically 12 hours after ignition. This time, it only took less than 6 hours. In the past, before the furnace was opened, the iron mouth was artificially rotated. The smoke and heat wave hit people, and the labor intensity was great. Very unsafe, burning oxygen is not easy to temper and hurt people, the consumption of various materials is huge, the whole furnace takes a long time, the process is difficult to control, this time the furnace is basically not burned, the material cost is reduced to the minimum, and the process control is smooth.

　　Chen Yongwei, the director of the factory, said happily, “This furnace was very successful! It is perfect! The automatic application technology of automatic oxygen lance has greatly boosted the successful opening of the blast furnace, which has brought our furnace level to a new level, indicating the technology-driven, Innovation has led to tremendous influence, and this is the magic weapon for our success!"
