Fire-Resistant Hydraulic Fluid (HFC)
Fire-resistant hydraulic Fluid (HFC) is designed for use in high-temperature, high-pressure, or environments where open flames are present. It significantly reduces the risk of oil mist ignition if leakage.
Types of fire-resistant hydraulic fluid and characteristic
| Type | Main components and characteristics | Applicable scenarios and limitations |
|---|---|---|
| Water Glycol Type | Containing 35% to 40% water, HFC utilizes the evaporation of water to absorb heat, thereby achieving a fire-retardant effect. | Suitable for systems operating under 2000 psi. Good stain resistance, but might corrode metals such as tin, lead, and zinc. Should not be mixed with conventional mineral oils. |

Main user for HFC hydraulic oil. Widely used in equipment that directly faces molten metalsor high-temperature radiation, such as coke oven doors, coke drums, blast furnace tops, reverb furnaces, and steel strandreeling machines, as well as the sliding gates of hot rolling mills.
Metal Casting and Forging
Die-casting machines processing Al, Mg, and Zn alloys operate with molten metal at high temperatures. Cracking in hydraulic tubes with traditional oil may easily lead to severe and potentially catastrophic fires. Therefore, the adoptation of HFC-based fire-resistant fluids is now mandatory.
Heavy-Duty Hydraulic Press
Hydraulic drive systems for large presses, hot forging presses, and high-temperature plastic molding machines.
