Wet injection lining technology has been successfully applied in 5100m ³ blast furnace of Shansteel, and many technological breakthroughs have been achieved in emergency repair of blast furnace injection lining!
On May 25, 2023, Rizhao Iron and Steel Plant of Shandong Iron and Steel Co., Ltd. carried out the medium repair project of 2#5100m blast furnace. West China Science and Technology Group undertook the construction of covering agent spraying and blast furnace wet injection lining.
In March 2023, the integrated general contracting project for the maintenance of No. 1 and No. 2 blast furnaces of a steel plant in Shanxi undertaken by Huaxi Science and Technology Group was successfully completed.
At 1: 06 on March 21, Shougang Tonggang 2#2680m blast furnace was successfully unrolled, marking the successful completion of the overhaul project of the blast furnace and its official commissioning. After the bath fire smelting of the blast furnace, the first furnace of molten iron flows out smoothly.
At the beginning of early spring, Vientie is updated. In the spring season, under the leadership of the board of directors of the group, Huaxi Technology, based on a new starting point, embarked on a new journey, created new brilliance, worked hard, competed for the first opportunity, and achieved good results frequently.
Shougang's 3#4000m3 blast furnace was put into operation on January 8, 2010. At present, due to the serious erosion of the furnace lining, it brings hidden dangers to the production safety, and because of the long-term addition of titanium furnace protection, the activity is reduced. In order to completely eliminate safety hazards, further achieve production and reduce consumption, at the end of June 2022, the 3# blast furnace will be organized to carry out maintenance operations, and Huaxi Technology Group will carry out maintenance projects such as furnace body spraying and lining.
Recently, the general contracting project for the integration of medium and medium repair of No. 6 2200m blast furnace in Valin Lianyuan Steel, undertaken by Huaxi Science and Technology Group, was successfully completed and put into operation on January 15. The project adopts international cutting-edge patented technologies such as integral pouring of tuyere belt, hot surface pouring of cooling wall, wet injection lining and intelligent hard pressure-in lining, which provide a strong guarantee for the blast furnace to achieve rapid efficiency and production.
This paper mainly introduces the application of the sixth generation of West China wet injection lining, the overall pouring of the tuyere area and the operation of the blast furnace after commissioning in 2022 on the No.5 (1500m ³) blast furnace of Liugang. After Liugang No.5 blast furnace was put into operation, the fuel consumption decreased significantly, the coke ratio in the furnace decreased to 554 kg/t, and the fuel ratio decreased from 546.5 kg/t to 513.6 kg/t. The problems of blast furnace gas leakage and cooling wall leakage were also completely solved, and various indexes entered the forefront level in the country, setting the best in the history of Liugang blast furnace indexes.
West China technology furnace cylinder integral pouring technology (patent number: ZL 201610353176.4) is a rapid repair of blast furnace hearth and ceramic cup way, has been widely recognized, the market share has reached 55.98.
Absolute global leadership! The patented technology of injection lining has achieved a major breakthrough in Shougang's 4000m grade blast furnace and won the "Excellent Organization Award"
[Quality West China Frequency Reaches New High] West China Science and Technology's World's First Integrated Whole Furnace Pouring Technology Successfully Applied in 2777m Grade Large New Blast Furnace!
On May 26, the 2777m ³ blast furnace construction project of Linyi Iron and Steel Investment Group Special Steel Co., Ltd., undertaken by West China Science and Technology Group, was successfully baked and entered the trial heating stage. It marks that Huaxi Science and Technology has successfully completed the task of integrated whole furnace pouring construction, witnessed the brilliant moment of high-quality development of Linyi Steel Investment Special Steel, and rewritten a new chapter in China's steel industry!
