Heat transfer analysis during cooling of die with use of water mist
Journal Title: Archiwum Odlewnictwa - Year 2011, Vol 11, Issue 3
Abstract
The paper presents the results of the heat transfer area during the cooling process of steel test die with water mist which consist the flow of air in the range 150÷350 l/min and 0.050.24 l/min of water. Temperature change in the thickness of die by means showing with the thermal curves and the temperature gradient and temperature distribution in the space between the nozzle and the cooled surface of the metal mold using a thermal imaging camera and thermocouples measurement. The course of changes in the temperature gradient and the received heat flux from the die while cooling its with the flow of air and water mist stream. It has been shown that the use of water mist with a variable flow of air and water controls the process of heat transfer process between the permanent molds, and a stream of water mist.
