Abstract

The invention discloses an electric glass melting furnace work simulating method and application thereof. The electric glass melting furnace work simulating method is based on a fluent software, and comprises the following steps: establishing a glass liquid geometric model, dividing grids, and drawing an obvious boundary between an electrode surface and a nearby adjacent insulating fire-resistant material area so as to add an electric field module; according to actual production situations, setting boundary conditions, and adding voltage boundary conditions to the electrode surface; simulating a temperature field, a flow field and an electric field of glass liquid to obtain glass liquid temperature field distribution, space flame temperature field distribution and speed field distribution conditions of different areas in the furnace; adopting a gabled temperature schedule as initial glass liquid surface temperature distribution, so as to obtain a final curve according to simulation coupling and curve coupling, and importing the final curve using a user-defined function for calculating; measuring a conductivity curve, a viscosity curve and heat conductivity coefficients, which change along with temperature, of the glass liquid in advance, and importing the conductivity curve, the viscosity curve and the heat conductivity coefficients into a model using the user-defined function. According to the electric glass melting furnace work simulating method and the application thereof, the working principle of the electric glass melting furnace is analyzed at a low cost.

Description

technical field [0001] The invention relates to the technical field of the principle of a glass electric melting furnace, in particular to a working simulation method of a glass electric melting furnace and its application. Background technique [0002] TFT (Thin Film Transistor, Thin Film Transistor) display screen is the mainstream display device on various notebook computers and desktop computers, so the demand for TFT liquid crystal glass substrates is relatively large. The usual furnace type for preparing TFT liquid crystal glass substrates is 5-30 tons per day. The thickness of TFT liquid crystal glass substrates is generally 0.3mm-0.7mm. It is a high-strength and high-hardness material. At 1580°C, it does not contain colored particles such as iron, is colorless and has high transmittance, and has low high-temperature conductivity. In the liquid crystal glass substrate manufacturing process, the furnace melting pool is a device for melting glass. The flame combustion...

Problems solved by technology

Using foreign software training is troublesome, the software cost is high, the service cost is also high, the application range is small, and there are a lot of immature places, and there is a lack of communication between users

Other companies directly purchase services, provide models and boundary conditions, and let foreign professional simulation companies conduct corresponding simulations. It usually takes several rounds of simulations. Each time they should go through procedures such as quotation and negotiation. The time is long, the procedures are complicated, and the communication is difficult. On the other hand, the cost is also very high

Most companies basically do not do simulation, and they have little grasp of the principles of related furnaces. They all rely on the accumulation of practical experience and need a long time to explore. Many electric melting furnaces cannot be produced normally for a long time.

[0007] At present, fluent software is also used for mathematical simulation of the combustion space of glass furnaces, but the results are not ideal and cannot meet the high requirements of TFT liquid crystal glass substrates
