Several Technologies for Hot Repair of Glass Kilns

1、 Vent the glass and prepare the damaged kiln bottom area, as described above. The predetermined quantity of refractory aggregate is transported by air flow through the spray gun to the damaged part of the kiln bottom. Same until the satisfied thickness stops. This method can also be used to operate without emptying the glass. It is necessary to know the convection condition of the glass so that the repair refractory can be sprayed in the correct direction and coagulated in the proper part of the damaged kiln bottom.
2、 Empty the glass in the kiln, and then drill holes in areas with greater corrosion at the bottom of the kiln or in "recesses" to discharge the glass in these smaller areas. Spray a flux onto the damaged area and partially heat it to completely remove the remaining glass adhering to the refractory material that needs to be repaired. A gunning material is sprayed directly onto the damaged kiln bottom through the spray gun until the desired thickness is reached.
