I believe everyone also knows that Guinness ’s fifth anniversary of Ruben is the only player who lost the challenge and smashed 17 pieces of tempered glass in our country. Many netizens have disputes about their challenge defeats, and many netizens have disputes about challenges and defeats. Is the quality of tempered glass in China too good? Is there a problem with the fixing method? Regardless of the result, the quality of tempered glass is very important. Because the glass needs to be heated to the corresponding temperature, the temperature of each part of the glass surface should be uniform, and the difference should not be too large, so we need to grasp three factors to manipulate this data.

First, choose a reasonable heating time. The heating power of the tempering furnace is determined. Generally, the set heating time is about 35-40 seconds per millimeter of thick glass. For example, the heating time of 6 mm thick glass is about 6 × 38 seconds=228 seconds. This calculation method is applicable to ordinary flat tempered glass with a thickness less than 12 mm. When the thickness of the glass is 12-19mm, the fundamental calculation method of heating time is about 40-45 seconds per 12 mm thick glass.

Secondly, according to the load of the electric furnace, select a reasonable heating temperature to effectively control the temperature in the furnace. The heating of glass in the tempering furnace mainly includes conduction, radiation and convection. The electric furnace load mentioned here does not refer to the area occupied by glass in the electric furnace, but refers to the relationship between the glass thickness, the heating temperature and the heating time.

Third, in order to achieve uniform heating, the placement of glass on the table is also very important. The reasonable placement of the discharge plate is mainly to ensure the uniformity of the longitudinal and lateral loads in the electric furnace, that is, the placement of the discharge plate of each furnace glass and the gap time of each furnace should be uniform.
