Function

L Lining the furnace
L Ramming or prefabricate the furnace wall, furnace foundation, roof (lid), water pipe and burner of the furnace steel rolling under flame environment
L Lining for Chemical equipment such as primary and secondary ammonia synthesis converter

Feature
L High refractoriness ---- low cement content, refractoriness up to 1650-1800° C, performing good under high temperature environment
L High strength----good performance under intermediate and high temperature
L Anti-erosion----strong ability to resist erosion from slag under high temperature environment

Usage
Adding water in proportion, stirring it into mortar, and then moulding by vibrating vibration moulding

Storage
25kg / bags, sealed package stored for 3 months at room temperature
