CORELESS INDUCTION FURNACES - IRON
Coreless Induction Furnaces have been a major primary melting unit in the ferrous foundry industry for many years.
The demands placed on the refractory lining are varied and sometimes very complex, bringing very different sets of circumstances that can affect the performance of the refractory lining, including:

THERMAL SHOCK
The constant thermal cycling of the refractory lining

LINING WEAR
Erosion due to the physical movement of the liquid metal.
Corrosion due to the aggressive chemistry of the metal 
and/or slag. 

GAS PENETRATION
The unwanted movement of gasses through the refractory lining such as carbon monoxide, zinc vapour, and zinc steam can be greatly reduced by our CALDETM SHIELD concept

SLAGBUILD-UP
The deposition of oxides on the refractory lining
