Angang blast furnace replacement project site Zhoukou!

Li Xinchuang, Dean of the Metallurgical Industry Planning and Research Institute and Secretary of the Party Committee, said: "Henan's steel production capacity is concentrated in Anyang. For a city, development not only depends on steel, but also building materials, chemicals, casting, etc., otherwise it is not conducive to overall development. The conditions for steel development in areas that are too dense should be restricted, and it is normal to tilt towards some areas with strong development desires, development momentum and advantages. Any industry must continue to optimize the layout, steel is particularly prominent, from the policy level proposed capacity replacement, that is, from the steel-intensive areas to have a comparative advantage of the reasonable transfer, this is the replacement of the premise and background.

Analysis of How to Operate Blast Furnace Before Opening After Spraying Lining?

Blast furnace spraying is a method of rapid lining of a blast furnace, which can be used to reduce the material surface for local spraying, regular furnace type, but also in the blast furnace overhaul when the overall spraying, shorten the blast furnace overhaul time, rapid recovery of production. It is an effective means for rapid lining of blast furnaces and is continuously used by most blast furnaces. The rapid overhaul of the blast furnace, the overall pouring of the furnace cylinder, the spraying of the furnace belly and the lining of the furnace body, greatly shortened the overhaul time, and soon resumed production.

Production Practice of Shougang 4000m ³ Blast Furnace Shutdown

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.

Blast furnace lining new navigation mark to reduce cost and increase efficiency-integrated whole furnace pouring technology

The integrated whole furnace pouring technology (patent number: ZL2020109906820) is a major technological revolution in the history of blast furnace lining, and it is a plan for large and medium repair of blast furnace. Its key advantage lies in the targeted development of structural refractory materials for each part of the blast furnace according to the reasons for erosion. The establishment of three new material systems and new technology theory, the use of materials require plastic forming, reaction enhancement, strict material requirements; Change the traditional construction process, a pouring molding, the whole blast furnace lining from bottom to top to form a complete whole. The technology has been successfully applied to a number of large-scale blast furnace projects in China, with a market share of 93.33 per cent.
