Process ovens in manufacturing plants are critical to production, but operating conditions such as high temperatures, 24/7 operation and heavy contamination make it difficult to ensure proper lubrication. LE has a range of superior high-performance lubricant formulations that assist customers worldwide with their process oven lubrication requirements.
Oven chains will operate freely and efficiently throughout the process if properly lubricated. Penetration of the pins and bushings is critical to prevent corrosion and provide sufficient lubrication.
Conversely, substandard lubrication leads downtime-inducing problems such as:
- Premature wear to the pins and bushings, which shorten chain life and causes rapid stretching, a critical failure in machines where equipment or machinery synchronization is a chain function.
- Links and strands becoming inflexible, causing rough operation, chains jumping off the sprockets and even breakage.
Reduced energy costs
Increased friction means more electrical energy is needed to operate the oven chain. Superior lubricants decrease friction, which reduces energy consumption and helps the lubricants eventually pay for themselves many times over.
Solid vs. liquid lubricant
There are two different ways to lubricate high-temperature chains: with a liquid lubricant or with a solid lubricant suspended in a carrier fluid. LE has both fluid and solid film lubricants, with recommendations made depending upon the specific needs of your application.
Fluid film lubrication is the regular oil film lubrication used in the majority of ambient temperature applications. It can also be used at higher temperatures, as long as the following are considered: the increased oxidation rate of the oil, the decreased viscosity of the fluid, and the volatility of the oil.
Solid film lubrication is preferred at high temperatures or in applications where it is impossible or undesirable to use a liquid. The solid lubricant is suspended in a liquid carrier designed to evaporate after the lubricant has been applied and, in the case of chains, after it has penetrated to the pin area of the chain. The result is a smooth, low-drag surface, which reduces friction, heat and wear, as well as electrical energy consumption.
