hp 200 mm graphite electrodes

What damages are prone to the hp 200 mm graphite electrodes mold during the hot pressing process?

Because the hp 200 mm graphite electrodes mold has many excellent performance, it is widely used in all walks of life. Although it has many benefits, it has a relatively short life and use times. Next, Cobowei hp 200 mm graphite electrodes mold manufacturer will briefly explain the damage that hp 200 mm graphite electrodes molds are prone to damage during hot pressing.

Oxidation is prone to occur when using hp 200 mm graphite electrodes mold for hot press sintering. This is because when the hp 200 mm graphite electrodes mold is hot-pressed, the protective measures of the reducing atmosphere are not done so that the hp 200 mm graphite electrodes and the air are in direct contact, so the surface oxidation phenomenon will occur in this high temperature environment, and The oxidation phenomenon will become more serious as the temperature rises. If the hp 200 mm graphite electrodes mold is very severely oxidized, the carbon element inside will be slowly consumed, leaving only part of the ash and carbon. Therefore, when using the hp 200 mm graphite electrodes mold for production, you will see that it has been used. There are some fine holes on the surface and some toner peeling off.

If the mold of hp 200 mm graphite electrodes is in direct contact with some tire powder containing diamonds, its contact surface will form a high-pressure state, which will cause a large difference in hardness between the molds of hp 200 mm graphite electrodes and cause extrusion deformation. In addition, if the hp 200 mm graphite electrodes mold hits the diamond tip during the hot pressing process, it is easy to produce some pits.
