Technical Field
[0001] This utility model relates to the field of melting furnace technology, and in particular to a precision temperature-controlled melting furnace for glass powder preparation. Background Technology
[0002] Glass powder is an inorganic, amorphous, hard, ultrafine particle powder. It appears as a white powder and is produced using high-temperature, high-purity raw materials such as silicon dioxide and aluminum oxide. Through an ultra-clean production process, it forms a disordered, transparent glass powder with stable chemical properties. It is an ultra-weather-resistant powder material with acid and alkali resistance, chemical inertness, and a low coefficient of expansion.
[0003] In the actual operation of traditional glass furnaces, glass raw materials of different densities and compositions are prone to stratification during the melting stage due to their differences in physical properties. The denser raw materials gradually sink to the bottom of the furnace under the action of gravity, while the less dense and lighter raw materials float to the top of the furnace, forming a distinct stratified structure. Existing methods of breaking up the stratification are often limited to local areas, with limited movement trajectories and ranges. In particular, it is difficult to quickly mix the raw materials at the top and bottom of the furnace. Therefore, we propose a precision temperature-controlled melting furnace for glass powder preparation. Utility Model Content
