Mobil SHC™ 630 iron and steel mill gearbox oil success story

Decreased amps by

3.3%
Primary metals molten steel

Situation

There are 16 sets of conveyors in the Coking Branch of Xinyu Iron & Steel Co., Ltd. The gearboxes of the conveyors were lubricated with a mineral oil that contributed to abnormal wearing of the gear and short oil drain intervals. In addition, the gearboxes were located at a relatively high position, increasing the safety risk and cost of maintenance.

Recommendation

The Mobil Lube Engineer conducted on-site inspections together with the customer and recommended Mobil SHC 630™ gear oil and Mobil Serv℠ Oil Analysis. As Mobil SHC 630™ gear oil has excellent high-temperature oxidation stability, low traction coefficient and high viscosity index, it is able to extend oil drain interval and improve the energy efficiency of the system.

Result

After the implementation of Mobil SHC 630™ synthetic lubricant, the plant managed to achieve a total annual savings of US $1,830. The benefits resulted from:

  • Decreasing the average operating temperature of the gearboxes by 6.7°C
  • Decreasing the electric motor current by about 3.3%

*This success story is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used. ExxonMobil shall include Exxon Mobil Corporation and its affiliates.
