Embodiment 1
[0039] A method for repairing a baking furnace, the specific steps are as follows:
[0040] (1) Pretreatment: Clean the surface of the roasting furnace with a high-pressure water gun, and remove the hidden and weak coating on the surface of the roasting furnace, so as to avoid the hidden and weak coating that is short-lived after repair because it cannot be found in time. Shedding and damage occur again within a short period of time, and the firm coating remains; the pressure of the high-pressure water gun is 70Mpa; the high-pressure water gun sprays silica sol;
[0041] (2) The first spraying repair: Spray the first layer of spraying paint on the surface of the pretreated roasting furnace with a jet machine. The thickness of the first layer of spraying paint is 0.2mm, and the particle size of the first layer of spraying paint is submicron. ;
[0042] (3) When the first layer of spray paint is viscous, spray a layer of glass fiber or carbon fiber on the first layer of spray p...

[0049] A method for repairing a baking furnace, the specific steps are as follows:
[0050] (1) Pretreatment: Clean the surface of the roasting furnace with a high-pressure water gun, and remove the hidden and weak coating on the surface of the roasting furnace, so as to avoid the hidden and weak coating that is short-lived after repair because it cannot be found in time. The shedding and damage will occur again within a short period of time, and the firm coating will remain; the pressure of the high-pressure water gun is 72Mpa; the spray of the high-pressure water gun is silica sol;
[0051] (2) The first spraying repair: Spray the first layer of spraying paint on the surface of the pretreated roasting furnace with a jet machine. The thickness of the first layer of spraying paint is 0.25mm, and the particle size of the first layer of spraying paint is submicron. ;
[0052] (3) When the first layer of spray paint is viscous, spray a layer of glass fiber or carbon fiber on the...
Embodiment 3
[0059] A method for repairing a baking furnace, the specific steps are as follows:
[0060] (1) Pretreatment: Clean the surface of the roasting furnace with a high-pressure water gun, and remove the hidden and weak coating on the surface of the roasting furnace, so as to avoid the hidden and weak coating that is short-lived after repair because it cannot be found in time. The shedding and damage will occur again within a short period of time, and the firm coating will remain; the pressure of the high-pressure water gun is 75Mpa; the spray of the high-pressure water gun is silica sol;
[0061] (2) The first spraying repair: Spray the first layer of spraying paint on the surface of the pretreated roasting furnace with a jet machine. The thickness of the first layer of spraying paint is 0.3mm, and the particle size of the first layer of spraying paint is submicron. ;
[0062] (3) When the first layer of spray paint is viscous, spray a layer of glass fiber or carbon fiber on the ...
