The JN series of furnace lining protector is used in electric furnace to adjust the furnace slag conditions, its main roles are as follows:

1. Reduce the iron oxide content of the slag to reduce iron loss and improve the metal yield;

2. Adjust the slag viscosity and surface tension to enhance the foaming effect, and further protect the furnace lining;

3. Strengthen the foaming slag effect and improve the utilization rate of electric energy;

4. The finished product is spherical, which can be added in a high-level silo to reduce dust pollution in steel mills.
