The main application scenarios of hydraulic oil in the steel industry are:
- Ironmaking process:
Blast furnace top equipment: (hydraulic mud cannon, opening machine, material distribution rotator)
Pain point: High temperature iron filings contaminate the oil, causing valve group jamming and high risk of sudden shutdown.
Hot air stove valve system:
Pain point: Long term high temperature operation accelerates oil oxidation, resulting in gum clogging of the filter element. - Steelmaking process
Converter/electric furnace tilting mechanism:
Pain points: High impact load, easy emulsification of oil, excessive moisture content corroding servo valves.
Hydraulic station for ladle refining furnace (LF/RH):
Pain point: Precision proportional valves require oil cleanliness to reach NAS level 7, and impurities can easily cause abnormal flow control of molten steel. - Rolling process (high fuel consumption!)
Hot rolling mill: (roughing/finishing hydraulic AGC system, coiler pinch roll)
Pain point: Metal dust+water vapor mixed pollution, requiring 2-3 oil changes per month, high cost.
Cold rolling plate shape control system: (bending roller cylinder, running roller mechanism)
Pain point: Excessive oil particle size directly leads to roller print defects on the surface of the strip steel.
Electric adsorption purification and reduction technology and equipment:
In 2017, it was listed as a “Major Environmental Protection Technology and Equipment Encouraged by the State” by the Ministry of Industry and Information Technology and the Ministry of Science and Technology.
