Determination of the material resistance to liquid metal splashes on protective clothing.

The materials test involves pouring defined amounts of molten metal onto the specimen, which is held at an angle to the horizontal on a mounting frame. Damage is assessed by placing a PVC foil directly behind and in contact with the specimen and noting the changes in the PVC foil after casting. Depending on the result, the test is repeated using a larger or smaller amount of metal until the minimum amount causing damage to the PVC film is determined. The molten metal is melted in a crucible using a high fre­ quency induction furnace. A high-performance glass fiber ratio pyrometer provides the reference variable for tempera­ ture control by determining the pouring temperature. The temperature of the melt is set and controlled from 700 to 1800 ºC by a temperature controller.

The tilting speed and the tilting angle can be controlled and adjusted via a stepper motor.
