Advantages and disadvantages of different height powder layers

1. Advantages and disadvantages of powder layer thickness Taking conventional soda-calcium wine bottle products as an example, under normal circumstances, the height of the powder layer is controlled at 200~300mm, and the production effect is the best. If the height of the powder layer exceeds this range, it is easy to cause uneven material, that is,

Characteristics of the powder layer of the glass electric melting furnace

The batch layer covered on the surface of the electric melting furnace is called the powder layer, and the height of the powder layer is an important parameter for the design of the glass electric melting furnace. Different from the traditional flame kiln, the electric furnace adopts a vertical melting process, and the powder layer is completely covered on the surface of the molten glass in the melting pool, and at the same time, the heat radiation of the melt to the kiln roof is blocked, so that the temperature of the upper space of the kiln is reduced to below 150 degrees Celsius, commonly known as "cold top". The volatile components in the batch are condensed in the powder layer and flow back into the molten glass, and gases such as carbon dioxide released during the melting process can easily pass through the powder layer and enter the space. The powder layer flows from top to bottom and melts continuously as the temperature rises, gradually completing the clarification and homogenization process.

On-site treatment of cover brick tilting problem and problem analysis

Measures to deal with the problem of tilting of cover bricks The top wire of the cover of an electric furnace built by our company is movable and can be twisted by hand. The reason is that the open-hearth furnace is not adjusted in time when it is kept warm and resumed production, which causes the lower pool wall or the top wire of the pool wall to shrink and the gap to become larger when the furnace is stopped. When the temperature rises, the gap becomes larger, and the bricks will go outward, causing them to sink. In order to solve this problem, a wire position can be welded between the supporting plate and the column to make the supporting plate fixed. In addition, the lack of power of the flowing fans, resulting in large temperature differences, may also be one of the reasons. Finally, the cover bricks and the fused bricks between the over-layer are not reinforced and also need to be strengthened.

Glass furnace: how to improve the service life of glass electric melting furnace

With the development of industrial technical glass, the life of glass electric melting furnace has also been extended, and the quality of glass has been significantly improved, which is related to the emergence of refractory materials, new species of refractory materials. In particular, it is closely related to the development of fused refractories in the last century. Due to the high density, wear resistance, good high temperature mechanical properties and corrosion resistance of glass electric melting furnace electric refractory material.
