Problems solved by technology
[0006] The invention solves the defect that the existing furnace repair adopts the surface gunning method, which cannot change the weak structure of the rat hole in the furnace, and the repair effect of the rat hole in the furnace is not ideal, and provides a glass melting furnace rat hole hot repair Method, by enlarging the mouse hole, filling it with silica bricks one by one, and then sealing it with silicon hot-fill material, changing the structure of the mouse hole to ensure that the part has a long service life and high-efficiency and energy-saving heat preservation effect
[0007] The present invention also solves the defect that the existing melting kiln hot patch is filled with refractory steel rods and refractory bricks, and cannot form an integral structure with the original melting furnace, which affects the service life of the repair, and provides a glass melting furnace rathole hot patch Method, by enlarging the mouse hole, filling it with silica bricks one by one, and then sealing it with silicon hot-fill material, changing the structure of the mouse hole to ensure that the part has a long service life and high-efficiency and energy-saving heat preservation effect

Embodiment
[0022] Embodiment: A method for hot-replenishing ratholes in a glass melting furnace, (1) first use a sitting water drill to ream holes in the furnace 1 where the ratholes 2 are located to form holes 3, the diameter of which is twice the diameter of the ratholes, The hole is cone-shaped, the diameter of the lower end of the hole is smaller than the diameter of the upper end, the depth of the hole is smaller than the depth of the mouse hole, and the bottom of the hole is 55mm away from the inner wall of the melting furnace. When drilling, cover the upper opening of the hole with a 30mm height of silicon polycrystalline rope;
[0023] (2) Clean up the hole to expose the silicon sealing material of the furnace, and fill the bottom of the hole with silicon hot filling material 4 after cleaning;
[0024] (3) Heating the zero-expansion silica brick 5 to be filled, the heating temperature is 300°C;
[0025] (4) Then fill the heated zero-expansion silica bricks layer by layer into th...

Abstract
The invention relates to a hot patching method for a mouse hole of a glass melting furnace. The method overcomes a defect that present melting furnace patching through a surface spraying manner cannot change weak structures of melting furnace mouse hole parts and is not ideal in patching effects. The method includes enlarging the mouse hole, gradually filling with silica bricks, and filling and sealing with a siliceous hot patching material layer by layer until fillers and the original melting furnace form an integrate structure. Through enlarging the mouse hole, gradually filling with the silica bricks, and filling and sealing with the siliceous hot patching material, the fillers and the original melting furnace wall are tightly combined, and no weak zone is formed at the mouse hole part, and therefore the mouse hole part after being patched has efficient and energy-saving thermal insulating effects and is long in service lifetime.
Description
technical field [0001] The invention relates to the field of repairing glass melting furnaces, in particular to a method for hot repairing ratholes in glass melting furnaces. Background technique [0002] Float glass melting furnace is one of the three major thermal processes in float glass production. As the heart facility of float glass production, its role cannot be replaced in the existing technology. Due to the high temperature operation of the float glass melting furnace, the wall is eroded, and holes appear in the crest, parapet, regenerator, etc. of the melting furnace, which will cause heat loss inside the melting furnace, which is not conducive to the thermal insulation effect of the melting furnace and the entry of impurities into the glass liquid. Then affect the glass quality and yield. [0003] In order to repair the ablated holes in the melting furnace, it is usually done by cold repair or hot repair. Due to the high cost of cold repair, hot repair is used fo...
