Abstract

The invention discloses a glass heating furnace and a heating method. A ceramic roller way for heating glass is arranged in a furnace. Glass is placed on the ceramic roller way. A radiation type air heater is arranged above the glass. A forced convection device is also arranged above the glass and is used to make hot air around the radiation type air heater carry out internal thermal circulation; during the circulation process, the force convection device can control the flowing speed and flow of hot air and is used to heat the upper surface of glass, thus the upper surface of glass can be uniformly heated relative to the lower surface, and the temperature of the upper surface of glass can be controlled. The high temperature convection device makes the idle hot air above the heater carry out forced internal thermal circulation so as to further reduce the energy consumption, moreover, the heating speed is increased, the heating becomes more uniform, and the heating time is shortened.

Description

technical field [0001] The invention relates to the technical field of glass heating and processing equipment, in particular to a glass heating furnace and a heating method. Background technique [0002] In the (physical) tempering process of glass, heating is the first process and the most important process that affects the final tempering quality of glass. In the current tempered glass equipment, the heating furnace is the part with the most complex control process and the greatest impact on tempered glass products. Controlling the heating process of glass is the prerequisite for producing high-quality tempered glass. [0003] The heating process of glass in the furnace is a process in which the temperature of the furnace drops, rises, and balances; When the glass is heated in the furnace, different heating methods are required for different periods of time to meet the heating needs of the glass. Reducing the processing defects caused by conventional heating methods to t...
