Automatic control method and system for blast furnace coil base electric locomotive

Abstract

A blast furnace coil base electric locomotive automatic control method and a blast furnace coil base electric locomotive automatic control system belong to the field of blast furnace ironmaking, and the method comprises the following steps: confirming that an electric locomotive is in an original position and no locomotive exists below a coil base, starting the electric locomotive to advance to a waiting position, and automatically stopping the electric locomotive; the molten iron vehicle set enters a coil base and is coupled with the electric locomotive in the waiting position, the electric locomotive drives the molten iron vehicle set to move, molten iron tanks on the molten iron vehicle set are aligned to a blast furnace tap hole one by one, and tapping is completed; after tapping is completed, the locomotive is commanded to enter a coil base, and the molten iron train set is pulled out; and the electric locomotive automatically stops after returning to the original position, and the electric locomotive runs to the waiting position according to a preset value of the distance from the original position to the waiting position and automatically stops to wait for tapping. The automatic control method and system of the electric locomotive are used for being matched with safe tapping of a blast furnace, automatic alignment of tapping of a coil base of an iron and steel enterprise is achieved, the labor intensity is reduced, and the safety risk of operators is reduced.

Description

technical field [0001] The invention relates to the field of blast furnace ironmaking, in particular to an automatic control method and system for a blast furnace platform electric locomotive. Background technique [0002] The electric locomotive, also known as the iron ox, is a special locomotive widely used in the alignment of molten iron under the blast furnace platform in iron and steel enterprises, and its shape is similar to that of a diesel locomotive. Alignment of molten iron means that the empty molten iron tank on the molten iron car is just moved to the directly below the tap hole of the stove, and the tap hole is at the center of the tank mouth. The molten iron wagon with empty iron ladle is called "empty wagon". Multiple molten iron wagons are connected together to form a hot metal wagon. The electric locomotive drives the hot metal wagon to tap iron. The molten iron tank is filled with molten iron, which is the "heavy wagon" state. , pulled out of the railway ...

AI Technical Summary

Problems solved by technology

[0006]1. At least one person should be arranged for each shift of each blast furnace to engage in the remote control operation of iron cattle, which did not give full play to the economic effect brought by the electric locomotive

[0007]2. The connection workers under the stove and the tank workers on the stove often need language communication and confirmation, and there is a risk of misoperation due to misunderstanding

[0008]3. The operating environment under the stove is harsh, and personal safety risks are great

There is a lot of iron sticking to the wall on the top of the bottom of the hearth, and there is a risk of injury if it falls; there is an iron ditch, slag ditch, and auxiliary ditch on the upper part, and there is a risk of iron leakage and injury; there is a risk of gas poisoning; human risk
