Embodiment 1

[0030] Such as figure 1 As shown, the executive mechanism is a driving mechanism for controlling the movement of the glass plate into the furnace, and the control process of the heating control method of the present invention is as follows:

[0031] First determine the heating furnace to be used, adjust the working temperature of the heating furnace according to the type of glass plate to be heated (such as low-emissivity coated glass, clear glass) and thickness information, and run the heating furnace at room temperature without load to reach the working temperature. Monitor the percentage of the number of temperature measuring units that have not reached the set temperature of the heating element in this state to the total number of temperature measurement units, and measure the percentage of the number of temperature measurement units that have not reached the set temperature at five different times The percentage of the number of units, average the five values, and the ave...

Embodiment 2

[0034] Such as figure 2 As shown, the executive mechanism is a driving mechanism for controlling the movement of the glass plate out of the furnace. The control process of the heating control method of the present invention is as follows:

[0035] First determine the heating furnace to be used, adjust the working temperature of the heating furnace according to the type of glass plate to be heated (such as low-emissivity coated glass, clear glass) and thickness information, and run the heating furnace at room temperature without load to reach the working temperature. Monitor the percentage of the number of temperature measuring units that have not reached the set temperature of the heating element in this state to the total number of temperature measurement units, and measure the percentage of the number of temperature measurement units that have not reached the set temperature at five different times Percentage of the number of units, average five values, the average is the s...

Embodiment 3

[0038] Such as image 3 As shown, the executive mechanism is a control mechanism that controls the opening of the cooling fan or changes from an idle state to a working state. The control process of the control method of the present invention is as follows:

[0039] First determine the heating furnace to be used, adjust the working temperature of the heating furnace according to the type of glass plate to be heated (such as low-emissivity coated glass, clear glass) and thickness information, and run the heating furnace at room temperature without load to reach the working temperature. Monitor the percentage of the number of temperature measuring units that have not reached the set temperature of the heating element in this state to the total number of temperature measurement units, and measure the percentage of the number of temperature measurement units that have not reached the set temperature at five different times. The percentage of the number of temperature units, and th...

Abstract

The invention provides a control method for a tempering technological process of a glass plate. The control method comprises the following steps: in a working process of a heating furnace, monitoring temperature information in the heating furnace in real time through temperature measuring units; counting up the quantity of the temperature measuring units, which do not reach pre-set temperature, through a control unit; calculating the percentage of the quantity of the temperature measuring units which do not reach the pre-set temperature in the quantity of all temperature measuring units; carrying out filtering processing on a calculation result; then comparing the calculation result of the filtering processing with a pre-set threshold value; when the percentage of the quantity of the temperature measuring units which do not reach the pre-set temperature in the quantity of all the temperature measuring units reaches maximum and minimum values, sending out an instruction to an executing mechanism by the control unit when the percentage is less than or equal to the pre-set threshold value in a decreasing process. According to the control method provided by the invention, a traditional control method taking time as evidences is changed and a novel control method for the tempering technological process of the glass plate is provided.

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 the softening temperature (for example, 600°C to 700°C), and then the tempering process is completed by rapid cooling, among which, the heating of the glass plate is an important process . [0003] According to the process requirements, before the glass plate is transported into the heating furnace, the heating furnace in the cold state or heat preservation state must be heated to the set temperature. In the prior art, the conventional method is: firstly, preset the temperature value achieved by heating according to the type, thickness and past operating experience of the glass plate; then, when the measurement result of the temperature sensor in the furnace reaches the set temperature value, In order to eliminate the influenc...
