Molten Metal Splash Resistance Test Equipment For Protective Clothing

Molten Metal Splash Resistance Materials Test Machine

Introduction:

Evaluate the material's resistance to liquid metal splash. During the test, an appropriate amount of molten metal is sputtered onto the sample placed at an angle. Attach a PVC film to the back of the sample to contact it. The damage is evaluated by recording the change of the PVC film after the sputtering process. According to the test results, repeat the test with a larger or smaller amount of metal until the damage to the PVC film is minimal.

A furnace with induction coil and high-frequency generator melts the metal. High-performance optical fiber two-color pyrometer is used for temperature control and measurement of sputtering temperature. The temperature controller adjusts the temperature between 700°C and 1800°C. The stepping motor controls the tilt speed and tilt angle. The cooling device uses the water flow connecting the inlet and outlet of the equipment for cooling.
