Application	The mortar, including corundum mortar, high alumina mortar and fireclay mortar, mainly used for blast furnace, hot blast stove, reheating furnace, annealing furnace and rotary furnace etc.
Characters	1. phosphate bonded dry mortar, consistence in quality, convenience in transportation   2. Easy to use, no need of ageing. It can be used by adding 25~27% water in site.   3. Good workability, easiness in coating, suitable setting time, making the joints completely sealed .   4. At different temperatures (high, middle or low), it possesses high bonding strength, good slag resistance and molten iron erosion resistance, excellent integrity and high strength structure.   5. Compared with common phosphate bonded mortar, this phosphate bonded mortar has the simplified construction process and short construction time. In consumption, furnace building efficiency and quality of furnace building, the mortar shows maximum superiority.
Packing	The product is packed in polyethylene-lined polypropylene knitted sack. 50kg per.
sack	Transporting and storage: moisture- and damage-proof.
