Intelligent molten iron conveying system

Abstract

The invention provides an intelligent molten iron conveying system. The system comprises a haulage motor body, a molten iron conveying vehicle body, a vehicle-mounted control system and a ground control system, wherein the vehicle-mounted control system is used for controlling motions of the haulage motor body and the molten iron conveying vehicle body according to a control instruction, the ground control system is used for collecting external environment information and controlling a ground advancing line of the haulage motor body and the molten iron conveying vehicle body according to the control instruction, and a centralized control platform is used for sending the control instruction to the vehicle-mounted control system and the ground control system. Automatic interaction of information and the control instruction is performed through the centralized control platform, a molten iron transporting vehicle achieves unmanned and organization scheduling intelligence in the whole molten iron transporting working process from a blast furnace casting field to a steel making transit station, the haulage motor operation efficiency is improved, the iron molten temperature drop is lowered, the road and haulage motor operation safety is improved, equipment damage and accidents caused by faults such as worker operation and judgment are completely eradicated, the operation risk is lowered, and personal safety of workers is ensured.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to an intelligent molten iron transportation system. Background technique [0002] Molten iron transportation is an indispensable production link in the long-process iron and steel smelting process. Constrained by production technology, land use restrictions, environmental protection and safety, etc., the current transportation methods of molten iron in domestic iron and steel complexes include railway transportation, road transportation and straddle vehicle transportation. Among them, molten iron railway transportation has been widely used because of its mature technology, rich actual production experience, good production rhythm flexibility, and safety and reliability. Joint operations involve a large number of refined operations such as alignment and connection. The characteristics of large-scale equipment, high temperature, and continuous production have higher requirements for the st...

AI Technical Summary

Problems solved by technology

[0004] 1) In the process of molten iron transportation, there are many staffing, and the cost of human resources is high

[0005] 2) Each driver needs to control the locomotive, unhook, signal confirmation, parking alignment, and identify obstacles on the track. One post has multiple jobs, and it takes 12 hours of uninterrupted work. The labor intensity is very high, and there are misjudgments and operational errors, etc. Security risks

[0006] 3) The temperature of the molten iron in the molten iron transportation vehicle exceeds 1000°C. During the transportation of the molten iron, there may be splashing of molten iron and the possibility of iron leakage. Operators frequently work in this area, which poses a high safety risk

In addition, affected by severe weather such as thunderstorms and heavy fog, the working environment is poor, and the personal status of the operator will affect the operation efficiency and may lead to misoperation, and the safety risk is also relatively large.

[0007] 4) During the entire molten iron transportation operation process, there are many operation links that personnel participate in. On the one hand, it is affected by the level of personal operation, and on the other hand, the connection time of each link is long to ensure sufficient working time and judgment of personnel, which affects the operating efficiency of locomotives and vehicles. The turnover rate not only increases the investment of transportation equipment, but also reduces the operating efficiency and increases the temperature drop of molten iron, which is not conducive to production cost and quality control
