Dry Ramming material for coreless induction furnace

Specifications

Metallurgical induction furnace dry ramming refractory material

Benefits:
1) Good performance to thermal shock, corrosion, erosion and abrasion resistance.
2) High refractoriness and excellent mechanical strength.
3) Both intermittently and continuously working mode are acceptable, reducing lining cracks.
4) Longer and stable life cycle to reach high efficiency.
5) Suit for all kinds of metal types, reduce residue and porosity of the products.
6) Labor and cost saving by convenient installation and maintenance.
