Blast furnace dust removal fan hydraulic system
Steel mill
Finland

Situation
A Finnish steel mill experienced ongoing problems lubricating its blast furnace dust removal fan hydraulic system in winter conditions. To maintain operations in extremely low ambient temperatures, the hydraulic system required the addition of electric heaters under a tarpaulin covering. In an effort to improve the efficiency of its blast furnace, the steel mill approached ExxonMobil to identify a lubricant solution capable of operating in extreme cold as well as summer conditions.

Recommendation
ExxonMobil engineers recommended the steel mill switch to Mobil DTE 10 Excel™32 hydraulic oil for its blast furnace dust removal fan hydraulic system. Formulated with a shear stable, high viscosity index base oil, Mobil DTE 10 Excel^™ 32 oil is designed to perform in a wide range of extreme temperatures.

Result
After transitioning to Mobil DTE 10 Excel ™32 hydraulic oil, the mill was able to operate equipment efficiently in temperatures averaging -15°C (5°F), and occasionally in temperatures as low as -27°C (-17°F). As a result, maintenance personnel no longer required supplement heating of tarpaulins to help maintain operating efficiency.

Mobil DTE 10 Excel^™32 oil has helped improve production reliability and generate savings by eliminating the need for heaters, tarpaulins and related maintenance costs.
