Embodiment 1

[0025] Such as figure 1 As shown, the executive mechanism is a driving mechanism that controls the glass plate out of the furnace, and the control process of the heating control method of the present invention is as follows:

[0026] First, get the total mass of the glass plate to be heated, according to the formula q 0 =cm△t Calculate the energy q needed to heat the glass plate from the temperature when it enters the furnace to the temperature when it comes out of the furnace 0， Among them, c is the specific heat capacity of the glass plate, m is the total mass of the glass plate to be heated, and Δt is the temperature difference between the glass plate entering the furnace temperature and the glass plate leaving the furnace temperature. The furnace temperature refers to the temperature set when the glass plate is heated in the heating furnace until it softens in the tempering process of the glass plate and meets the conditions for the furnace to be released. Usually, the v...

Embodiment 2

[0032] Such as figure 2 As shown, the executive mechanism is the control mechanism of the cooling fan, and the control process of the control method of the present invention is as follows:

[0033] First, get the total mass of the glass plate to be heated, according to the formula q 0 =cm△t Calculate the energy q needed to heat the glass plate from the temperature when it enters the furnace to the temperature when it comes out of the furnace 0， Among them, c is the specific heat capacity of the glass plate, m is the total mass of the glass plate to be heated, and Δt is the temperature difference between the glass plate entering the furnace temperature and the glass plate leaving the furnace temperature. The furnace temperature refers to the temperature set when the glass plate is heated in the heating furnace until it softens in the tempering process of the glass plate and meets the conditions for the furnace to be released. Usually, the value range of the furnace temperatu...

Abstract

A glass plate tempering process control method. After the glass plate is sent into the heating furnace, the monitoring unit monitors the energy consumed by the heating element of the heating furnace in real time, and transmits it to the control unit for comparison with the set threshold; when heating When the energy consumed by the heating element of the furnace is greater than or equal to the set threshold, the control unit sends instructions to the actuator to control the action of the actuator to complete the corresponding tempering process. The present invention changes the traditional control method based on time, monitors the energy consumed by the heating element of the heating furnace in real time through the monitoring unit, and can control the heating process of the glass plate more scientifically and accurately, thereby accurately judging the time when the glass plate comes out of the furnace. The phenomenon of insufficient heating temperature or over-burning of the glass plate is avoided, and the quality of the finished tempered glass is improved.

Description

technical field [0001] The invention relates to a glass production process, in particular to a glass plate tempering process control method. Background technique [0002] In the tempering process of the glass plate, the glass plate is first heated to a softening temperature (for example, 600°C to 700°C), and then the tempering process is completed by rapid cooling. Among them, the heating of the glass plate is an important process control process. In the prior art, the heating process of the glass plate is usually controlled by the heating time, that is, the thickness of the glass plate is multiplied by the time coefficient, and the thickness of the glass plate is estimated. Heating time, when the set heating time is reached, the glass plate comes out of the oven. This method of relying on experience to control the heating process of the glass plate has the following technical defects: 1. The heating temperature of the glass plate is not easy to be accurately controlled, an...
