A MANDREL LUBRICANT FOR HOT FORMING SEAMLESS
MANDRELCOAT is a proven indigenous Substitute for the “Deltaforge 1096S"
In continuous Tube rolling mills, seamless tubes are shaped by rolling an ingot preform heated to 1200C to 1300C over a Mandrel. After each rolling operation, the Mandrel is cooled to about 100C and then coated with Lubricant prior to commencing the next rolling cycle.
The Lubricant should be smokeless, must provide optimum sliding of the ingot on the mandrel during rolling and should result in an optimum quality inner surface of the tube. The time available from Mandrel cooling to next rolling operation is about 5 seconds, Hence the Lubricant should be sprayed and dried to form a uniform, strong and adhesive film of preferred thickness on the mandrel within this time. The MANDRELCOAT meets all these requirements effectively.The Mandrelcoat forms a smooth lubricating protective film on application. The resulting coating is fast drying, resistant to water and shows excellent adhesion to the mandrel surface. The formulation is such that a coating thickness of upto 30microns is formed and being water based is smokeless, ensuring a clean work environment and zero pollution.
It has been tested for shelf life, suspension properties and pot-life when in use and when left standing. Mandrelcoat shows excellent
