Quench oil serves two primary functions. It facilitates hardening of steel by controlling heat transfer during quenching, and it enhances wetting of steel during quenching to minimize the formation of undesirable thermal and transformational gradients which may lead to increased distortion and cracking. Heat transfer in this region is exponentially dependent on the oil’s viscosity, which will vary with the degree of oil decomposition. Oil degradation is often accompanied by sludge and varnish formation. The presence of sludge may cause non-uniform heat transfer, increased thermal gradients Another source of non-uniform heat transfer is quench oil contamination due to water.
The Filtek Centrifugal Oil Cleaner model CK600 is a self contained skid powered by an 80 LPM pump+motor to remove contamination of quenching oils thereby reducing viscosity and helping in effective heat transfer. This will provide correct hardening of jobs and reduce rejections. The Centrifuge being a cleanable unit has no consumable parts.
