Ceramic welding for tunnel kiln crown

Post Time:Jun 13,2016Classify:Glass QuotationView:703

Scoured by frequent flame and effected by temperature gradient,  refractory material structure of  ceramic tunnel kiln, which had run more than half a year, changed due to reduction reaction between incompletely combusted  carbon monoxide and liner brick. Meanwhile, low-melting phase formed due to chemical reaction brought down the thermal mechanical properties of material, which caused plastic deformation of vaults brick and subsidence of dual vaults in firing zone of ceramic tunnel kiln, thus threating structure safety of the entire kiln. By combining nondestructive cutting technology and ceramic welding technology, the company successfully solved the problem in the crown of tunnel kiln.
