Description

technical field [0001] The invention belongs to the technical field of glass preparation, and in particular relates to a laboratory-used molten glass stirring control system and method. Background technique [0002] In the field of glass application research and development, before large-scale industrial mass production of new formula glass, it is necessary to carry out trial production research in the laboratory, that is, first prepare glass samples, then test various performance parameters of the samples, and finally analyze whether their performance meets the design requirements. need. In laboratory glass preparation, high-temperature melting of glass is a key process step. It is a process in which the batch material is heated at high temperature to form a uniform, bubble-free glass liquid that meets the forming requirements. This process includes: melting the batch material, clarification , stirred and homogenized, and then thermoformed to obtain a glass sample. Among ...

AI Technical Summary

Problems solved by technology

The equipment used in laboratory glass melting is generally a muffle furnace or a box furnace. These traditional electric furnaces often have the problem of uneven furnace temperature distribution due to poor sealing of the furnace body or uneven power distribution of electric heating elements, especially the furnace bottom temperature. Low, resulting in the actual temperature rise of glass melting inconsistent with the set system

At the same time, the stirring and homogenization process usually relies on manual stirring with a platinum stirring rod, especially when there is a lot of glass liquid, the stirring effect is poor, and problems such as uneven stirring are prone to occur, and it is extremely inconvenient, time-consuming and labor-intensive. Accurately grasping the stirring speed cannot realize consistent management of the stirring process, resulting in poor homogenization effect of the glass in the molten state, making the formed glass samples prone to quality problems such as uneven composition, visible bubbles, streaks, inclusions, etc. Affect and interfere with the performance test of the sample, the test results often cannot reflect the real situation of the new formula glass, which restricts the progress of glass application research and development
