Application of oil circulation temperature control machine in die casting industry
Oil circulation temperature control machine (heat conduction oil heater): coal, heavy oil, light oil combustible gas and other combustible materials as fuel, heat conduction oil as heat carrier. The use of circulating oil pump forced liquid phase circulation, the heat energy is transported to the heat equipment, and then returned to the reheated direct-flow special industrial furnace, heat transfer oil, also known as organic heat carrier or heat medium oil, as an intermediate heat transfer medium in the industrial heat transfer The application of the process has more than fifty years of history.
Application of Heat Transfer Oil Heater in Die Casting Industry
The control of die surface temperature is very important for the production of high quality die castings. The temperature of the mold will affect the flow of the molten metal on the surface of the mold cavity, especially for thin-walled parts with long flow routes.
In order to make the molten metal fill the cavity before solidification, in addition to the design of shortening the filling time, the gate speed can be increased (but it is easy to produce turbulence) to increase the mold temperature. In addition, large area and high surface requirements of the casting, but also need a higher and stable mold surface temperature, can reduce the cold and surface defects.
Uneven or inappropriate mold temperature can also lead to dimensional instability of castings, deformation of castings during the production process, resulting in defects such as thermal pressure, mold sticking, surface depression, internal shrinkage cavities and thermal bubbles. When the mold temperature difference is large, the variables in the production cycle, such as filling time, cooling time and spraying time, have different degrees of influence. In addition, the life of the mold will also be due to the impact of supercooling and overheating and lead to expensive steel to produce hot cracking and other problems.
