Втвърдяване на покритието чрез нагряване на алуминиевия блок

Coating curing by heating the aluminum block

Objective: To heat an aluminum block for a cylinder liner coating curing application.

Equipment:

• Ambrell EKOHEAT® 30 kW, 50-150 kHz solid state induction power supply with a workhead;
• Single position four-turn helical coil.

Frequency: 89 kHz

Material: Aluminum block - 4" x 4" x 4.5" (102 x 102 x 114 mm)

Temperature: 400 °F (204 °C)

Testing: The aluminum part was placed inside the helical coil with temperature indicating paint applied to both the inside and outside of the block. The power was turned on and the part began to heat. After 90 seconds the temperature indicating paint began to melt.

Benefits:

• Speed: The client’s oven had a heating time of 20 minutes, so the time savings are considerable with induction.
• Precision and repeatability: Induction is a highly repeatable process, unlike an oven.
• Floor space: Induction takes up less floor space than an oven.
