Ceramic welding
repair technoloqy
The ceramic welding powder is the material to repair the damaged area of refractory, composing the various furnaces such as glass melting furnace, coke oven, converter, etc. and without stopping operation of furnace, it can easily and quickly repair while a furnace is in use.
The ceramic welding powder mixes the metal fuel such as Al, Si, Mg, Zr, etc. with refractory raw materials which have the same elements as the refractory, and injects the mixture through excess oxygen to work hardfacing welding on the damaged area quickly.
