Description

technical field

[0001] The invention belongs to the technical field of metallurgical industry, and relates to a replacement system and method for a movable main iron trough of a blast furnace. Background technique

[0002] The main iron trough of the blast furnace is an important part to realize the separation of iron slag. Due to the erosion of iron slag, the lining of the main iron channel is easily damaged and requires regular maintenance. In the past, the fixed main iron channel was often used, that is, the main iron channel was fixed on the casthouse platform, and the inner lining was stacked, sprayed and baked on site. This process takes a long time and affects the normal tapping of the blast furnace. In order to ensure the tapping cycle of the blast furnace, it must be satisfied by increasing the number of iron channels. In recent years, active main iron channels have appeared, and the maintenance time of the main iron channels can be shortened by replacing the main...

Examples

Embodiment 1

[0029] Embodiment 1: as Figure 1 to Figure 5 As shown, a blast furnace movable main iron channel replacement system, the system includes a casthouse platform 7 for transporting the main iron channel; a support beam 4; a lifter 5; a hoisting cable 3; a lifting beam 6; the lifting beam 6 The two ends of each are provided with hoisting cable through holes 12; flatbed truck 1; connection plate 9, and bolts 10 and nuts 11 that are matched with the connection plate 9.

[0030] When it is necessary to replace the movable main iron trough of the blast furnace, the components included in the above-mentioned system are operated according to the following steps: (1) two support beams 4 are installed on the casthouse platform 7; (2) two supports of each support beam 4 (3) One end of the hoisting rope 3 is clamped in the hoisting device 5, and the other end passes through the hoisting rope through hole 12 of the hoisting beam 6 so as to connect with the connecting plate 9 Fasten the conn...
