Claims
- 1. A method of uniformly spraying an ordinarily high viscosity nonaqueous lubricant containing solid additives onto the metal working surfaces of heated dies in a forging press comprising the steps of:
- heating said lubricant to approximately 170.degree. to 300.degree. F. to reduce its viscosity to approximately 1.0 centipoise;
- continuously recirculating a constant volume of said lubricant at a pressure of approximately 30 to 70 pounds per square inch and a temperature of approximately 170.degree. to 300.degree. F. from the source of heat to a spray nozzle;
- hydraulically atomizing said recirculating lubricant by selectively feedng said lubricant through said nozzle under said pressure; and
- directing said atomized lubricant onto said metal working surfaces.
- 2. A method as set forth in claim 1 further comprising:
- monitoring the temperature of said recirculating lubricant.
- 3. A method as set forth in claim 2 further comprising:
- monitoring the heat loss of said lubricant from recirculation to atomization.
- 4. A method of applying an ordinarily high viscosity, petroleum based, nonaqueous liquid lubricant containing solid additives with a viscosity of from approximately 300 to 2000 centipoise at 104.degree. F. onto the metal working surfaces of heated dies of a forging press comprising the steps of:
- heating said lubricnt to a temperature of approximately 170.degree. to 330.degree. F., such that the viscosity of said lubricant approximates that of water at standard temperature and pressure;
- continuously recirculating a substantially constant volume of said lubricant from the source of heat to a spray nozzle at a pressure of approximately 30 to 70 pounds per square inch;
- hydraulically atomizing said lubricant by feeding said lubricant through said nozzle solely under said pressure of approximately 30 to 70 pounds per square inch; and
- directing a uniform layer of said lubricant spray onto said metal working surfaces of said forging dies.
- 5. A method as set forth in claim 4 wherein said lubricant is heated to a temperature of approximately 250.degree. to 280.degree. F.
