Design And Retrofit LF Ladle Furnace Capping Machine Hydraulic Control System

The steel-making of Shouqin launch the steel ladle adding project in order to reducesteel temperature drop, reduce production cost, improve product quality and meet therequirements for saving energy and reducing consumption, which is the key equipmentof the steelmaking process online. Based on LF ladle furnace capping machine hydrauliccontrol system, this article analysis the production process of adding ladle equipment andprinciple deeply, emphatically expounds the equipment hydraulic system design andretrofit, electrical automation system design and transformation, system management andfailure analysis, etc.First narrative adding ladle cover in steelmaking process and the development oftechnology, emphasis on the types and characteristics of ladle capping machine. Thenanalysis technology of adding ladle of shouqin company. Combined with the practicalapplication of LF furnace ladle capping machine, points out the problems existing in thesystem of equipment, modify the original hydraulic system design, and automationreform combining the reliability theory and equipment design, so that Solved someproblems which affect production,such as the sealed equipment operation is not smooth,the foundation bolt fracture when lifting mechanism rotary. Last increased theautomation program, get rid of the backward situation that only in manual operation, sothat adding ladle equipment reached the domestic leading level.Adding ladle equipment in steel-making and refining equipment plays an importantrole, directly affect the temperature drop of molten steel, the consumption of rawmaterials and refractory material,the cost of steel. At the same time,In reducingequipment failure rate, improving production efficiency, the article studied theapplication of reliability theory in the management of equipment system.Last states the development characteristics of equipment management and themanagement pattern of shouqin company in detail, lists the common equipment failurehandling and operation and maintenance management system, analyses the processefficiency and direct economic benefits after the equipment transforming.It is of great significance to improve the steel-making productivity, equipment maintenance management level and technology application level by studying the ladlecapping machine hydraulic control system of LF furnace and reliability management,which consolidate the foundation of improvement of economic efficiency of the company.
