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 cold repair and cleaning of a flat glass melting furnace, which comprises the following steps: S11, emptying the raw materials in the raw material bin of the glass kiln head; S12, adding tin particles into the raw material bin of the glass kiln head; S13, passing through a raw material feeder Push the tin particles into the glass melting furnace; S14, stop heating the glass melting furnace after the tin particles are melted into tin liquid and precipitate under the glass liquid; S15, after the glass liquid is cooled and hardened into a glass body, and the temperature is at When it is above the melting point, set a horizontal through hole on the side of the glass melting furnace, and the position of the through hole corresponds to the bottom surface in the glass melting furnace; S16, let the tin liquid leak out from the through hole; S17, after the tin liquid leaks, the glass body Form a suspended cavity with the bottom surface of the glass melting furnace; S18, cut open the glass body and clean the glass body; use the temperature difference between the melting point of the glass liquid and the tin liquid to form a suspended cavity under the glass body to eliminate the gap between the glass body and the inside of the glass melting furnace. The large-area adhesion on the bottom surface facilitates the cleaning of the vitreous body and greatly improves the work efficiency.
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 ...
