General Information of Gunning Mass
Gunning mass refractories is product that is used in various part of furnace as Monolithic Refractories that added hydraulic alumina cement to refractory aggregate.
Our Company is producing suitable product to installation and working condition through a quality control, this product which is minimizing alumina cement for using various dispersants and ultra fine powder so it has excellent abrasion resistance, erosion resistance, spalling resistance and chemical resistance . It widely used in part of various industrial furnace including incinerator, nonferrous metal furnace etc.
Features of Gunning Mass
High refractoriness, High refractoriness under load
High density, low porosity
Good slag resistance and corrosion resistance
High strength and wear resistance
Good resistance to flake performance
Good thermal shock stability
Scouring resistance
Good hot strength
