Continuous measurement of remaining lining thickness
The SAVEWAY® system allows the continuous measurement of remaining lining thickness during furnace operation. It is the only technology used in security monitoring, which measures the actual remaining lining thickness. In addition to visible signs of wear, such as erosion and worn-out areas, covered wear conditions are detected reliably, like dangerous metal penetrations and metal fins.
Metal fins represent an enormous risk potential for coreless induction furnaces. They can cause short-circuited coil turns if they remain undetected. Contact between liquid metal and cooling water could lead to an explosive molten discharge – an immense and possibly fatal danger for workers and plant.
The system also offers the option to switch between “melting mode” and “drying mode”, so that the sinter charge can be monitored on metal penetration. The detection of coil leakage, such as those occurring on coreless induction furnaces, completes the service range of the SAVEWAY® Technology.

The SAVEWAY® system can be used wherever ceramic refractory material is used and a temperature gradient exists. The main application area is the measurement of remaining lining thickness on coreless induction furnaces.

To measure the wear condition, electrode panels (sensors) are installed on an insulating surface. On a coreless induction furnace, the sensors are used in place of the usual slip-plane on the coil grout.
The measurement is based on the distinctive temperature dependence of the electrical resistance of refractory materials. The 16-stage wear indicator shows each segment separately. Critical conditions are immediately displayed on the operators’ display screen.

This separate parallel display always shows the same screen as on the control and visualization unit, without time delay. Longer distances can be reached; for example, next to the furnace instead of in the control room.
There are two different variants:
External opti panel
External TFT display
With the help of this feature, the system automatically identifies which furnace shells are currently connected to the system. The identified furnace shell will be monitored in the wear and history display.
With the aid of the gradient analysis, a critical increase of penetration for each segment will be displayed separately. That means metal is penetrating the lining at an unsafe rate. A critical increase of wear levels can be set differently for each segment.

The peak level indicator refers to the temporary display and storage of the maximum wear level per segment until manually reset. Quick and easy view of the maximum wear is possible. This quick overview is an enormous benefit, for example at, shift changes.

This feature allows the automatic switching between operator displays of all furnaces connected to the system. Activation and deactivation is done manually. This display is advantageous; especially at greater distances between furnace and the control and visualization unit.
The three-step status stack (ANDON lights), which is designed for floor and wall installation, shows the current wear condition of the furnace as Green, Yellow or Red.

The dual display allows you to monitor the wear condition of two different furnaces on one screen.
