Whilst the principal objective of the selective roll cooling system is to achieve optimum strip flatness and efficient heat transfer from the roll; ensuring this is achieved by applying minimum coolant volume is a key engineering and production priority.
This results in a consequential reduction in the coolant volume being applied and reprocessed for recovery as spent coolant, which can significantly reduce primary operating costs.
Efficient application of the coolant and lubrication media also ensures minimal generation of detritus and particulates in the process consequentially improving surface quality, strip brightness and rolled in defects such as micro-inclusions.
Lechler systems are "designed in" to the existing mill configurations as an integral part of the rolling process ensuring optimum interaction and integration with the rolling process.
Lechler provides participative contributions to ensuring clients' process needs are considered a priority.
