Embodiment approach

[0075] According to a preferred embodiment of the present invention, the method further includes: controlling the tractor 8 through the terminal to tow the corresponding molten iron tank 9 to carry out the alignment operation, and at the same time judging whether the alignment is successful according to the weight feedback of the molten iron weighing mechanism , and then send a signal of success or failure of alignment;

[0076] When the terminal receives the alignment success signal, the terminal controls the swing direction of the swing nozzle 7, and at the same time controls the blast furnace 2 to tap iron, so as to receive iron. During the iron receiving process, the terminal controls The tractor 8 carries out the work of advancing and transporting the molten iron tank 9 and replenishing the iron receiving unit.

[0077] In the above-mentioned preferred solution, the molten iron weighing mechanism judges whether the alignment position of the molten iron tank 9 is within th...

Embodiment 1

[0090] In this embodiment, a remote-controlled electric tractor 8 and a molten iron track scale without foundation pit are installed on the molten iron transportation line of the casthouse 1 under the blast furnace 2 to realize the safe top-flow dismantling operation of molten iron. Moreover, the electric tractor 8 can transport the heavy tanks that have reached the iron standard to the safe area outside the casting yard 1 through remote control during the tapping process of this trip, and then the connecting personnel will carry out the unloading operation of the heavy tanks, which effectively solves the problem. Previously, there was a problem that personnel could not enter casthouse 1 for top-flow unloading of heavy tanks. The molten iron track scale without foundation pit effectively solves the problem that the amount of molten iron loaded meets the standard, and at the same time effectively controls the problem that the amount of molten iron loaded exceeds the standard and...

Abstract

The invention belongs to the technical field of blast furnace molten iron transportation, and particularly relates to a blast furnace molten iron transportation system and a blast furnace molten iron transportation method. The system comprises a blast furnace with a swing flow nozzle, a casting house, a molten iron transportation line unit and a steelmaking area, wherein the molten iron transportation line unit is composed of a first line and a second line. The system further comprises an iron receiving unit, an optional coordination tank and a plurality of tractors, wherein the iron receiving unit is composed of three molten iron tanks, one of the three molten iron tanks is arranged on any one of the first line and the second line, and the other two of the three molten iron tanks are arranged on the spare one of the first line and the second line. According to the system, the molten iron tanks are designed into the iron receiving unit in a 1+2 alignment mode, the molten iron is subjected to iron receiving in multiple batches, the operation efficiency of the molten iron tanks can be improved, the number of the required online molten iron tanks is remarkably reduced, and the number of the generated tail tanks is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of blast furnace molten iron transportation, and in particular relates to a blast furnace molten iron transportation system and a blast furnace molten iron transportation method. Background technique [0002] During the casting process of the blast furnace, since the casting house belongs to the high-temperature molten metal and metallurgical gas operation area, it is easy to cause safety accidents such as burns and gas poisoning. From the perspective of safety, it is strictly forbidden to enter the casting house for operation during the casting process. Affected by this, hot metal tanks need to be aligned at one time, and the quantity is guaranteed to complete one trip of molten iron tapping. However, the alignment mode is basically fixed, and the number of tail tanks is not easy to control, resulting in the need for more molten iron tanks at one time for blast furnace tapping , The number of hot metal tank...
