Lubrication System (e.g., oil nozzles): Pressure 2-10 bar

Component Specifications

Definition

A specialized lubrication system in continuous casting mold assemblies that delivers controlled amounts of lubricant (typically oil-based) through precisely engineered nozzles to critical contact surfaces between the mold and the solidifying steel strand. This system reduces friction, prevents sticking, minimizes wear on mold components, and facilitates smooth strand withdrawal during the continuous casting process.

Working Principle

The system operates by pumping lubricant from a reservoir through a distribution network to strategically positioned nozzles. These nozzles atomize or precisely direct the lubricant onto the mold walls or designated contact areas. The lubrication creates a thin film that separates moving surfaces, reduces thermal stress, and prevents the formation of solid bridges between the strand and mold, ensuring continuous operation.

Materials

Nozzles: Typically stainless steel (e.g., AISI 316) or ceramic for corrosion and high-temperature resistance. Tubing: Stainless steel or flexible high-temperature hoses. Reservoir and pumps: Carbon steel or stainless steel with seals compatible with industrial lubricants.
