1. When controlling the moisture of granularity-sensitive raw materials such as calcite white jade, in addition to conventional drying and drying treatment, microwave drying technology can be used to achieve efficient and accurate dehydration. Microwaves can penetrate the inside of the material, causing water molecules to generate high-frequency vibration friction and heat generation, which is 3-5 times more efficient and more evenly distributed than traditional hot air drying. At the same time, the near-infrared spectrometer is used to monitor the moisture content of raw materials in real time, and when the detected value deviates from the set range, the operating parameters of the drying equipment are automatically adjusted to form a closed-loop control system to ensure that the moisture content of raw materials is stable in the process requirement range.
2. As an important additive of special glass, the particle size distribution of barium oxide has a significant impact on the optical properties of glass. Studies have shown that glass refractive index uniformity is best when the average barium oxide particle size is controlled at 1 - 3 microns. In actual production, barium oxide can be ground to the required particle size by jet grinding technology, which uses high-speed air flow to make particles collide and rub against each other, avoiding impurity pollution caused by mechanical grinding. In addition, barium oxide is easy to react with moisture in the air to form barium hydroxide at high temperatures, so vacuum packaging or nitrogen-filled packaging is required to isolate moisture and ensure the purity of raw materials.
3. The application of barium sulfate and barium carbonate in glass production is developing in the direction of functionalization. Through surface modification technology, a layer of titanium dioxide film is coated on the surface of barium carbonate particles, which can significantly improve its shielding ability against ultraviolet rays and is used in the production of radiation-resistant glass. In terms of the application of barium sulfate, it is compounded with graphene to prepare a new glass raw material, which can endow the glass with excellent thermal conductivity and meet the needs of heat dissipation glass for electronic equipment. At the same time, with the stricter environmental protection regulations, industrial barium carbonate with low lead and low sulfur content has become a development trend, enterprises need to establish a more stringent impurity detection process, and use inductively coupled plasma mass spectrometry (ICP-MS) technology to detect heavy metal impurities at the parts per million level to ensure that products meet green production standards.
4. In order to realize the fine control of the particle size and uniformity of glass raw materials, the digital management system has gradually become the industry standard. The chemical composition, particle size distribution, moisture content and other data of raw materials are entered into the cloud database, and combined with machine learning algorithms, a prediction model of raw material performance and finished glass quality is established. When the parameters of a batch of raw materials fluctuate, the system automatically recommends adjustment plans, such as changing the ratio of raw materials and optimizing the mixing process. At the same time, the 3D laser particle size analyzer is used to monitor the mixed raw materials in real time to ensure that each raw material meets the process requirements and ensure the quality stability of glass products from the source.

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.
Structural reinforcement and design recommendations for the breast wall Problems in the design and reinforcement of the breast wall structure. It is recommended to consider tiling and supporting structures in the design to avoid voids and deformations. At the same time, on-site construction can also be carried out according to the actual situation, and various materials and methods can be used for reinforcement. In addition, the problem that the exposed steel bricks in the oven process are not affixed with thermal insulation paper leads to serious explosions, which reminds everyone to pay attention to this problem and avoid similar situations.
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.
