Control of a holding furnace

Each menu has an area with menu-specifi c displays. Additional buttons or displays are provided there. The following menu-specifi c display is shown in the start menu; it allows you to switch to all other menus.

Setting the surface temperatures of the furnace housing

On the furnace housing the surface temperatures are monitored at 6 points with NiCr-Ni thermocouples. The furnace fl ange and the furnace cables are water-cooled; each cooling circuit consists of a main line and a bypass. In the main line as well as in the bypass there are both a temperature and a fl ow monitoring.

Switching the system on again after an EMERGENCY STOP

If one of the emergency stop buttons is pressed for safety reasons, this immediately interrupts the tilting operation of the system. The power feed of the inductor remains unaffected by this.

Control of the furnace cooling

The inductor is water-cooled. The water temperatures and fl ow rates of the 4 circuits are monitored and displayed on the touch panel.

Control of a crucible furnace

The “Power“ menu displays the electrical parameters as values and bars. The operating mode can be changed here. The menu and the displayed values change depending on the selected operating mode.

Temperature settings for furnace cooling

In this menu the limit values for temperature and fl ow rate can be set. In the event of an overtemperature fault in a single cooling circuit, the power is switched to a low level to protect the furnace. In the event of a malfunction of the fl ow rate in a single cooling circuit, the power is switched off to protect the furnace.
