The hot stove is one of the important equipment in the blast furnace production process to ensure the stable operation of the hot stove , is the key to improving blast furnace supply air temperature . In this paper, a large-scale iron and steel enterprises hot blast furnace longevity of the implementing agencies for the industrial background , identify the problems by the implementing agency for hot blast furnace process in - depth research and analysis on the hot stove , the stove perform scheme of institutions longevity . First, a brief introduction to the process of the hot air furnace , hot stove implementing agencies load characteristics , according to the iron-making environment of high temperature , high pressure, heavy dust features , proposed the use of hydraulic as hot stove implementing agencies longevity scheme . From the overall design of the hydraulic system of the implementing agencies , and the hydraulic system of hydraulic impact leakage problems were studied, effective anti- hydraulic shock leak measures . Secondly, it analyzes the advantages and disadvantages of the hydraulic system commonly used in oil inlet throttle speed control loop and back to the oil control Circuits , oil return control Circuits suitable for high-temperature environment as the system loop ; stability , fast and speed stiffness , modeling and analysis the dynamic characteristics of the oil return control Circuits , and propose measures to improve the system dynamic characteristics of quality . Next, the design of the implementing agencies to provide electrical power source system, hydraulic system , a distributed control system ( DCS ) ; DCS software configuration technology research , according to the the hot stove process requirements , control system software for I / O configuration and point configuration , use the SAMA picture shows the programming language , basic tools of AutoCAD , the preparation and valves of the hydraulic system control program , draw man-machine interface control software ; DCS anti-jamming technology research to identify interference was mainly due to take effective anti-jamming measures . Finally on the hot blast furnace implementing agencies longevity implementing and industrial applications , the system is proved the feasibility , reliability and stability , extend the life of the implementing agency , has laid a good foundation for other hot stove actuator technology update .
