Heat-Hardened Refractory Mud

1/

Each year, Taiwan’s metal casting heavy industries generate several thousand tons of waste casting sand that is mostly utilized in low strength ready mixed concrete. This material is made with recycled casting sand through processes such as pulverization, grinding and screening to produce recycled mullite sand and refractory granules of varying sizes that is mixed in a special formula heat-hardened refractory mud with granularity of <3mm is mixed with water to form a refractory material that can be applied to the walls and pan of kilns; it is resistant to temperatures of 1710-1790℃. more
