Introduction to Hualing Lianyuan Iron and Steel Co., Ltd.: since the beginning of this year, the continuous casting bench team in the 210 converter operation area of the maintenance center of Hualing Lianyuan Iron and Steel Group Co., Ltd. has carried out key research activities to solve the problem of high oil consumption in the hydraulic system of the continuous casting machine, and the oil consumption cost has been reduced by more than 100000 yuan per month year on year. It is understood that the hydraulic system of the continuous caster in the 210 ton converter operation area At that time,

since the beginning of this year, the continuous casting bench work team in the 210 converter operation area of the maintenance center of Valin Lianyuan Iron and Steel Group Co., Ltd. has carried out key research activities to solve the problem of high oil consumption in the hydraulic system of the continuous casting machine, and the oil consumption cost has been reduced by more than 100000 yuan per month year on year

it is understood that the oil consumption of the hydraulic system of the continuous caster in the 210 ton converter operation area is 40 ~ 50 barrels per month, and even hundreds of barrels in most cases, which is much higher than that of similar enterprises. Most hydraulic systems are in the high temperature (2) yield stage. When the stress exceeds the elastic limit and reaches the zigzag curve, the cleaned oil in the environment is dirty. At the same time, some equipment assembly and sealing components have quality problems, resulting in too many oil leakage points and high oil consumption. For this reason, the operation area 6. Package and process performance test instruments (including package drop test instrument, package impact test instrument, friction and wear test instrument, bending test instrument, straightening machine, etc.); The target of only 20 barrels per month was set. In order to reduce oil consumption, a specialized hydraulic technology team was established in the operation area to establish equipment operation control files and explore equipment deterioration trend and maintenance and repair cycle. At the same time, through consultation and cooperation with 210 converter plant, the operation error points that are easy to occur are counted, and the fine operation control is implemented. At present, the hydraulic oil consumption is only 1 ~ 2 barrels per month, which reduces the hot shutdown time and improves the slab quality
