Then, the cut-off valve 241 of the non-return device 24 is opened, the air supply device s 23 and the non-return device 24 are connected to each other, and the wire feeding device 25 is activated to give the titanium-containing wire 251, and the titanium-containing wire 251 is The introduction port 249 of the introduction member 244 of the squeezing device 24 is inserted into the positioning hole 248 of the locating member 242 of the M341700 through the muffler 243, and is inserted after the cutting valve 241 is inserted. The inner tube 234 of the air supply member 231 of the air supply device 23 is then introduced. The connecting section 211 of the guide 21 and the inserting section 212 are inserted into the furnace body 31 of the blast furnace 3 from the front end opening of the blast tube 321 to repair the cylinder part 3ΐ 〇 where the 'muffler 243 is used to reduce leakage The noise generated by the shielding gas, and the positioning member 242 is connected to each of the elastic members 247 between the slider 246 and the housing 245, even if the titanium-containing wire 251 is partially deformed and bent. 246 can still be touched on the titanium-containing wire 251, which can effectively reduce the leakage of the shielding gas. Repairing the hearth portion 311 of the blast furnace 3 with the blast furnace line maintenance device 2 has the following advantages: 1. Small impact on production: since the blast furnace line maintenance device 2 is a coal injection pipe 322 via the blast nozzle 32, titanium is contained. The wire 251 is fed into the furnace body 31 of the blast furnace 3 from the front end opening of the blast tube 3, and hardly affects the original production working conditions of the blast furnace 3, and the titanium-containing wire 251 enters the furnace body 31 from the coal injection pipe 322. The usability of the peephole 324 of the air blowing nozzle 32 is maintained, so that the operator can continue to observe the production situation of the blast furnace 3 and the condition of the maintenance work from the peephole 324. 2. The maintenance effect is good. Since the titanium-containing wire 251 enters the furnace body 31 from the coal injection pipe 322, the titanium-containing wire 251 can be melted in the hearth portion 311 closer to the furnace body 31, resulting in the furnace body 31. The furnace portion 311 contains a high concentration of titanium carbide and titanium nitride, which contributes to the improvement of the maintenance work of the 10 M341700. 3. High safety: Through the protective gas and the anti-reverse device μ, the high-pressure and high-temperature gas in the blast furnace 3 will not leak out during maintenance work, ensuring the safety of the workers.
