How to Select High-Temperature Chain Oil
In high-temperature chains, it is not enough for the lubricant to simply withstand the temperature. The oil must penetrate the chain pin-bushing area, evaporate in a controlled manner, leave low residue, and have the correct viscosity.
Temperature is not the only criterion.
The furnace air temperature and the actual metal temperature of the chain joint may differ. Measurements should be taken at the chain's operating temperature if possible; lubricant selection should be based on this actual temperature.
Evaporation and residue formation
The tendency of base oil to evaporate at high temperatures can increase consumption. Unsuitable oils can oxidize, forming hard carbon or varnish-like residues. This can restrict the movement of the chain joint and increase energy consumption.
Viscosity and application system
The oil must be fluid enough to reach the application point and enter the joint. However, very low viscosity can lead to high consumption and dripping problems. The pump and nozzle structure of the automatic lubrication system must also be taken into account.
Sectoral examples
The requirements for dyeing plant conveyors, ceramic kiln chains, textile stenter chains, and food processing chains differ from one another. In the food sector, hygiene requirements such as NSF H1 may also come into play.
Conclusion
The selection of high-temperature chain oil requires a combined assessment of temperature, viscosity, evaporation rate, residue tendency, and the application system.
