Abstract

The invention relates to a molten iron tank alignment tractor below a blast furnace. The molten iron tank alignment tractor comprises a tractor body controlled by a tractor master control system. The tractor master control system is provided with a master control module and is in wireless communication connection with an outer remote control unit through a remote control signal receiver. A rotary encoder is installed on an output shaft of a speed reducer of the molten iron tank alignment tractor and connected with a tractor alignment control system. The tractor alignment control system at least comprises a single-chip microcomputer, a key circuit, a display module and a communication module. The communication module is additionally in communication connection with the tractor master control system and a blast furnace casting control system. The molten iron tank alignment tractor can replace an internal combustion locomotive to finish molten iron tank alignment operation, remote alignment is completed through remote control, operation is convenient, alignment is accurate and reliable, efficiency is high, and mis-operation and molten iron splashing can be prevented. Equipment operation and the automatic charging process are both remotely controlled, the man-machine contact frequency is greatly reduced, and the safety accident rate is reduced. A breakthrough is made in blast furnace casting alignment operation.

Description

technical field

[0001] The invention relates to a tractor, in particular to a tractor for alignment of molten iron tanks under a blast furnace. Background technique

[0002] In iron and steel enterprises, molten iron smelted in blast furnaces is generally transported to steelmaking plants in molten iron tanks for further processing. There are two railway lines under the taphole of the blast furnace. Before tapping, two rows of molten iron tractors are equipped with two rows of molten iron tanks. During the tapping process, in order to ensure the continuity of tapping, after one tank is filled, the molten iron is sent to In the hot metal tanks of another railway line, a row of hot metal tanks just filled with one tank is pulled forward by a diesel locomotive for a distance of one hot metal tank, and the next hot metal tank is aligned with the tap hole (alignment), so that the two rows of molten iron can The iron is tapped alternately between the tanks until all the molten ir...
