Method for controlling glass to be heated in glass toughening process

Abstract

The invention relates to a method for controlling glass to be heated in the glass toughening process. The method includes the steps that a plurality of temperature sensors used for detecting the temperature of the glass in a heating section are arranged on the heating section of a glass toughening furnace, the temperature sensors are connected with a control center of the glass toughening furnace, the control center is further connected with a transmission mechanism controller of the heating section, the temperature needing to be reached by the glass on the heating section through heating is set in advance according to different sorts of glass to be toughened before the glass is heated, when the temperature sensors detect that the temperature of the glass reaches the set temperature in the glass heating process, the control center sends an instruction to the transmission mechanism controller, the glass is moved out of the heating section, the next process is executed, an original mode that heating time is judged according to the experience of operators is changed, the percent of pass of finally-obtained toughened glass products is high, and the quality of the products is stable.

Description

technical field [0001] The invention relates to the technical field of glass tempering, in particular to a method for controlling glass heating during the glass tempering process. Background technique [0002] The physical tempering method of glass requires uniform heating of the glass to be tempered in the tempering furnace to close to the softening point, and then rapid cooling to complete the tempering of the glass. Traditional glass tempering equipment is used to control the heating process of the glass. If the glass needs to be heated to the tempering temperature, it is roughly calculated according to the heating time of 40 seconds per millimeter of ordinary float glass. In this way, ordinary 6MM float glass The heating time is roughly 240 seconds. Due to the different glass raw materials, different softening points, different colors, and different thickness errors, it is impossible to calculate the heating time so accurately through the above method, and the operator n...
