Embodiment Construction
[0025] The invention provides a method for cold repair and cleaning of a flat glass melting furnace, which comprises the following steps:
[0026] S11. Empty the raw materials in the glass kiln head raw material warehouse;
[0027] S12, adding tin particles to the raw material warehouse of the glass kiln head;
[0028] S13. Push the tin particles into the glass melting furnace through the raw material feeder;
[0029] S14, such as figure 1 As shown, after the tin particles are melted into tin liquid 3 and precipitated under the glass liquid 2, stop heating the glass melting furnace 1;
[0030] S15. Combine figure 2 As shown, when the molten glass 2 is cooled and hardened into a glass body 4, and the temperature is above the melting point of the molten tin, that is, 300-700°C, a horizontal through-hole 5 is drilled on the side of the glass melting furnace 1, and the position of the through-hole 5 is the same as The bottom surface in the glass melting furnace 1 is correspon...

The invention discloses a method for clearing a plate glass melting furnace during cold repair. The method comprises the following steps that S11, raw materials of a glass furnace head raw material bin are emptied; S12, tin granules are added into the glass furnace head raw material bin; S13, the tin granules are pushed into the glass melting furnace through a raw material batch feeder; S14, afterthe tin granules are melted into tin liquor and precipitated under molten glass, the glass melting furnace stops being heated; S15, after the molten glass is cooled and hardened into a glass body andwhen the temperature is above the tin liquor melting point, a horizontal through hole is formed in the side of the glass melting furnace, and the through hole corresponds to the bottom face in the glass melting furnace in position; S16, the tin liquor is drained from the through hole; S17, after the tin liquor is drained, a suspension cavity is formed between the glass body and the bottom face inthe glass melting furnace; and S18, the glass body is chiseled and cleared. The suspension cavity is formed below the glass body through the temperature difference between the molten glass and the tin liquor melting point, large-area adhesion of the glass body and the bottom face in the glass melting furnace is eliminated, thus the glass body is cleared conveniently, and the working efficiency isgreatly improved.
Description
technical field [0001] The invention relates to the technical field of flat glass manufacturing, in particular to a cold repair and cleaning method for a flat glass melting furnace. Background technique [0002] In the field of flat glass manufacturing, especially in the field of float forming and calendering, the glass melting furnace is responsible for melting the prepared raw materials into glass liquid. The glass melting furnace is generally made of refractory materials. The operating temperature is 1580 ° C. Years later, cold repairs are required to replace damaged refractory bricks. [0003] During cold repair, the undischarged molten glass will condense in the furnace to form a solid glass body, which needs to be cleaned manually. The glass body is a huge whole with high hardness. The glass body is adhered to the bottom surface of the melting furnace, so manual cleaning is difficult and bulky. Contents of the invention [0004] The object of the present invention ...
