- Commodity name: Furnace top
SA-BL series spinel materials have the characteristics of high density, high hardness, and low porosity, which can effectively reduce the loss of refractory materials caused by flue gas scouring and chemical corrosion.
The Kivset furnace roof needs to withstand mechanical scouring and chemical erosion from flue gas, and also needs to have high resistance to thermal shock damage. SA-BL series spinel refractories can be used.
