Embodiment 1
[0024] A method for arranging a steelmaking ladle hot repair station, said method comprising the steps of:
[0025] S1: Lay rails from the tapping span to the non-tapping span, and make a special ladle span car.
[0026] S2: Make an installation and maintenance platform, and lay supporting energy pipelines.
[0027] S3: Make and install a dust removal cover on the maintenance platform, and install a dust removal system in the dust removal cover.
[0028] S4: Use a metallurgical crane to place the ladle that needs to be repaired on the special span car, transfer it to the non-tapping span hot repair station for maintenance, and then return it to the tapping span for standby.
Embodiment 2
[0030] On the basis of Example 1, the special ladle over straddle vehicle described in the step S1 includes a over straddle vehicle frame 2, and one side of the over span vehicle frame is provided with a ladle horizontal placement platform 1, the The other side of the straddle vehicle frame 2 is provided with a vehicle-mounted maintenance platform 3 .
Embodiment 3
[0032] On the basis of Embodiment 1 or 2, in the step S1, the end of the rail is provided with an emergency traction device.

The invention discloses a steelmaking ladle hot repair station arrangement method. The method comprises the following steps: S1, paving a steel rail from a tapping span to a non-tapping span, and manufacturing a special ladle straddle carrier; S2, manufacturing and installing a maintenance platform, and laying matched energy pipelines; S3, manufacturing and installing a dust removal cover on the maintenance platform, and arranging a dust removal system in the dust removal cover; and S4, placing a steel ladle needing to be maintained on the special straddle carrier through a metallurgical crane, transferring the steel laddle to a non-tapping straddle hot repair station dust removal cover to be maintained and pouring the steel laddle back to the tapping straddle for standby application aftermaintenance is completed. According to the method, safe and environment-friendly hot repair of the steel ladle is realized, the technical problems that the existing scheme of arranging a steel ladlehot repair station on a steelmaking tapping span molten steel lifting line does not meet the safety management requirement and has huge potential safety hazards are solved, the molten steel lifting line is effectively avoided, and once accidents such as unhooking and tipping of the steel ladle occur, ladle hot repair operators can be prevented from being injured.
Description
technical field [0001] The invention relates to the technical field of hot repair stations for ladles, in particular to a method for arranging hot repair stations for steelmaking ladles. Background technique [0002] According to the "Opinions of the National Coal Mine Safety Supervision Administration of the State Administration of Work Safety on Supporting the Steel and Coal Industry to Resolve Overcapacity and Achieve Development Out of Difficulties": "Strengthen law enforcement and clarify that iron and steel companies require steel factories to carry out casting cranes that lift high-temperature molten metal without using fixed gantry hooks, personnel gathering places (including meeting rooms, activity rooms, lounges, changing rooms, etc.) are set in the area affected by the hoisting of high-temperature molten metal", and the Ministry of Emergency Management on the investigation and management of hidden dangers of major production safety accidents in steel enterprises in...
