and form a bond equivalent to the bond of a newly casted lining.
ENDLESS LINING SYSTEM Refractory linings are a consumable and subject to wear under extreme high temperatures and pyro-chemical conditions. Tis requires linings to be replaced periodically when 50% wear has occurred. Since traditional repair methods cannot bond well to worn refractory linings, a repair will therefore not bring the lining into the same condition as new. So plant engineers are faced with two choices. Either they repair a lining and get a compromised lifetime, or they break out the entire lining and replace it, throwing the good and expensive remainder of the lining into the bin.
Te use of gel-bonded linings is the
answer to this problem as it enables the plant engineer to repair the worn lining with a refractory castable that has the same properties as the original lining and bonds with its nano particles into the micro porosity of the existing lining. Tis cost-effective repair eliminates the cost and time to demolish a worn lining and reduces the amount of refractory castable used. Te result is a repair that is cost-effective, fast and brings the lining back to its original property.
REAL-WORLD CASE STUDY A recent case study on the endless lining system from Refraline showcases its technical advantages on a torpedo ladle in South Africa. Te table on p32 details the improvements that the Refbond nano-gel brought about.
IN SUMMARY We hear a great deal about new technologies with buzzwords such as “nanotechnology”, and mostly we cannot imagine how these new technologies can be applied in our daily lives. Here is a real-world example of a development being taken from the laboratory environment into a real industry problem and making a notable difference – both financially and technically.
