Automatic temperature control and energy-saving system of glass toughening furnace

Abstract

The invention discloses an automatic temperature control and energy-saving system of a glass toughening furnace, which comprises a sheet loading table and a heating furnace, the sheet loading table isprovided with a first roller way, the heating furnace is provided with a convection fan, a second roller way and a heating wire, and a first glass position detection sensor and a second glass position detection sensor are arranged at two ends of the sheet loading table. The position and shape of the glass can be known through the first glass position detection sensor, the second glass position detection sensor and the glass shape detection equipment, and the heating wire above the glass can be controlled to increase the heating power according to the position of the glass. The heating power of the heating wire above the non-glass is reduced, process parameters such as a temperature curve, a heating curve and the like which are most suitable for the current batch of glass are generated, edge warping caused by uneven heating of the glass is prevented, white marks are avoided, the product quality is stabilized, and the purpose of saving energy is achieved.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to an automatic temperature control and energy-saving system for a glass tempering furnace. Background technique [0002] The current process of glass tempering is that the glass as a whole enters the heating furnace, moves to the end of the heating furnace and then starts to reciprocate for heating. During this process, the convection system and the heater are all turned on. [0003] The applicant of the present invention found that when the glass enters the furnace, due to physical characteristics and uneven heating, the two sides will warp, causing one or several small areas in the middle of the glass to contact the quartz roller table, and leaving one or several foggy lines on the glass. Traces, and its process parameters such as temperature curve, power curve, convection curve, etc. are all set fixed data. It is impossible to adjust each batch of glass under manual ope...
