The ceramic welding process is a mehod used to repair refractories in industrial furnaces at operating temperature.As a result,operational costs due to shutdowns and production are minimized and sometimes eliminated.
Ceramic welding uses a mixture of ceramic and metallic,which are conveyed in an or oxgen/ar mixture through a system of hoses anf specialized cooling pipes to the repair area.The heat from the furnace atmosphere and base refractory initiates an exothermic reaction between the metals and oxygen.The heat generated from this exothermic reaction is substantial enough to melt or soften the ceramic particles as they pass though the reaction zone before they are deposited onto the surface of the base refractory.The heat also softens or melts zone before they are deposited onto the surface of the base refractory.The heat also softens or melts the surface of the base refractory being repaired.Thus,upon cooling,a ceramic or crystalline bond is crested between the base refractory and the ceramic weld repair mass.Subsequent layers of repair are ,in turn,deposited onto the area until the desired thickness is achieved.
The repair material used in the ceramic welding process varies with the type of substrate that is being repaired.These include silica,fused,fused,silica,magnesia,fireclay,AZSand high alumina,as well as other materials.Depending on the repair criteria,the selection of equipment can also affect the weld quality.
