Fused Spinel
The Fused Spinel produced by us has high bulk density and good color.it is strong to resist corroding and anti-detonation is better.it dopts high pure MgO and Chemical Al 2 O 3 to smelt by EAF.Apply to the proof of EAF and basic oxygen furnace.steel ladle,intermediate zone cement rotary kiln,etc.
