Background
When the blast furnace is tapped, a layer of slag shell usually floats on the slag iron surface of the main channel, and when the main channel of the blast furnace is used for treating carbon-containing iron-zinc briquettes (or called pellets), the slag shell of the main channel can block the briquettes and keep the briquettes to react in the main channel. However, in the tapping process of the blast furnace, workers often run into the main runner sand dams to cause excessive drop of the liquid level of the main runner slag iron, so that slag shells of the main runner are suspended or cracked due to collapse of the slag shells, and float away along with slag flow, so that no slag shells are opened on the slag iron surface of the main runner, and the added main runner blocks freely float along with slag flow, flow into the slag runner and enter the slag flushing, so that the processing blocks cannot be processed; when the temperature of slag iron in the middle and later stages of blast furnace tapping is higher and higher, the physical heat of molten iron reaches above 1490 ℃ and even far above 1500 ℃, slag shells on the slag iron surface layer of a main channel of the blast furnace are quickly melted, and sometimes the slag shells remain little or completely disappear, so that the added main channel block mass freely floats along with slag flow, flows into a slag channel to enter slag flushing, and can only be forced to stop processing the block mass, so that the temperature of slag iron in the middle and later stages of tapping is high, and the block mass cannot be processed in a time period favorable for processing the block mass. On the other hand, in order to increase the reduction reaction rate and the reaction effect of the agglomerated iron and to increase the recovery rate of iron, it is necessary to block the agglomerated iron in the middle section of the main channel so as to keep the agglomerated iron reacting in the region where the reduction reaction of the iron in the front section of the main channel is good, and to prevent the agglomerated iron from drifting to the rear and end regions of the main channel. The utility model patent 201910931080.5 discloses a method for preventing a lump from being blocked by a high-temperature-resistant object at the middle and rear sections of a main ditch, which aims at solving the problem that a slag crust is easy to melt and disappear and the lump flows into the slag ditch to enter slag flushing. However, the blast furnace main ditch has high slag iron temperature, mud cannons and tapping machine equipment are arranged at two sides of the main ditch, workers need to perform various operations in the main ditch area to treat various problems, the site working environment is poor, the blocking ball block (namely, a block-shaped object for blocking the block) is adopted to block the block, the problems of short service life of the blocking ball block, high-temperature deformation, damage and inconvenience in operation of the equipment, certain safety hazard and the like are also faced, certain difficulty exists in specific implementation, and the utility model patent does not describe the structure of the device in the process of describing the method.

The heat insulation asbestos plate 7 is used for heat insulation protection of the hanging steel ring 4, the lifting hanging chain 5 and the baffle ball block hanging beam 6. The hanging steel ring 4, the lifting hanging chain 5 and the blocking ball block hanging beam 6 are made of heat-resistant stainless steel materials, so that the hanging steel ring 4, the lifting hanging chain 5 and the blocking ball block hanging beam 6 have enough strength to hang the blocking ball block 1 and are not influenced by high-temperature deformation. The baffle ball block 1 is manufactured by casting steel ladle casting materials and is formed by baking and solidifying.
Fifth embodiment: the blast furnace main ditch is processed to contain the carbon iron zinc briquette and adopts the blocking ball block device, adopts the electric hoisting hanging type blocking ball block device, and is shown in the accompanying figures 8 and 9. Before tapping, checking a blocking ball block blocking block device hung on the smoke hood 12, adjusting the blocking ball block 1 to a proper height, enabling the middle section of the main ditch to be wider, and blocking the block 3 by adopting two blocking ball blocks 1. When the blast furnace is in tapping, the iron slag level of the main runner 2 drops too much due to the operation of a sand dam of the main runner by workers, so that slag shells of the main runner are suspended or collapse and break, the phenomenon that the slag shells in the main runner float away and the added main runner block flows into the slag runner to enter the slag flushing is avoided, a motor speed reducer 13 is immediately started, a winch 9 is driven to rotate to reduce the height, the height of a blocking ball hanging beam 6, a lifting hanging chain 5 and a blocking ball 1 hung by a hanging steel ring 4 is gradually reduced in the downward lowering process of a steel wire rope 8, and the blocking ball enters a certain depth below the iron slag level of the main runner according to the requirement of blocking balls, so that the block 3 in the main runner is blocked from reacting at the front section of the main runner before the blocking ball 1 in the main runner. And after the main ditch sand dam is completely poked by a sand muzzle worker in front of the furnace and the liquid slag on the surface layer of the main ditch is discharged, the winch 9 is driven to rotate by starting the motor reducer 13 to increase the height, and the blocking ball block 1 is lifted upwards to a certain height capable of avoiding the tapping machine and the mud gun to work for standby. The heat insulation asbestos plate 7 is used for heat insulation protection of the hanging steel ring 4, the lifting hanging chain 5 and the baffle ball block hanging beam 6. The hanging steel ring 4, the lifting hanging chain 5 and the blocking ball block hanging beam 6 are made of heat-resistant stainless steel materials, so that the hanging steel ring 4, the lifting hanging chain 5 and the blocking ball block hanging beam 6 have enough strength to hang the blocking ball block 1 and are not influenced by high-temperature deformation. The ball baffle block 1 is manufactured by utilizing waste refractory materials of a continuous casting tundish under steelmaking production and replacement and is baked.
The utility model adopts the blocking ball block device for blocking the carbon-containing iron-zinc briquette in the main ditch of the blast furnace, solves the problems that the briquette in the main ditch does not have a slag shell because of the excessive temperature of a sand dam or slag iron of the main ditch operated by workers, and the like, and flows into a slag ditch to enter slag flushing, so that the briquette cannot be continuously processed.
