Float glass melting furnace

Abstract

The invention discloses a float glass melting furnace, comprising a melting region which is arranged at the forepart of the melting furnace, wherein a charging opening is arranged at the front end of the melting region; a hot spot is arranged in the middle of the melting region along the length direction; a furnace bank is arranged at the hot spot of the melting region; the length dimension of the furnace bank is same as the width dimension of a pool of the melting region; the height of the furnace bank is 50-70% of the depth of the pool of the melting region; and the thickness of the furnace bank is 300-400mm. By adopting the structure, the float glass melting furnace can maintain the stability of two circulating glass melt flows in the melting furnace and prolong the residence time of the glass melt in the melting furnace to contribute to the clarification and the homogenization of the glass melt, and can prevent the dirty materials at the bottom of the pool of the melting region from directly flowing to a cooling region and prevent a part of the glass melt in the cooling region from reflowing to the melting region to be reheated, thereby improving the melting quality of the glass melt, saving the energy, and lowering the loss of the float glass melting furnace.

Description

technical field [0001] The invention relates to a float glass melting furnace, in particular to a float glass melting furnace which improves the structure of the melting part. Background technique [0002] Float glass is currently the main production process for flat glass, and the melting furnace is one of the most important thermal equipment in the float glass production process. For a long time, strengthening the scientific research on glass melting furnaces and improving the design level of glass melting furnaces has always been a subject of concern and attention to glass production researchers and designers. Improving the structure of the furnace can not only reduce the cost of glass production, but also improve the quality of glass. [0003] Glass melting is the process of adding batch materials into the melting furnace and heating at high temperature to form a uniform, bubble-free (that is, reduce bubbles, streaks and stones to the allowable level) glass liquid that ...

Problems solved by technology

However, the bubbling at the bottom of the pool is easy to damage the bricks at the bottom of the pool, the material at the bottom of the pool is easy to leak, or the bubbling tube is easy to block, which limits its application.

As a simple and easy measure, kiln sill has been discussed and tried for decades, but it is only used in bottle glass kilns and other small glass melting kilns. It is currently used in float glass melting kilns in my country. still not used
