Embodiment Construction

[0026] see figure 1 , figure 2 , image 3 , a kind of heating furnace for glass tempering provided by the present invention has a furnace body 2, and a closed heating space is formed in the furnace body 2 (comprising frame and insulation material);

[0027] On a horizontal plane in the heating space of the furnace body 2, a plurality of horizontal roller tables 1 are arranged at intervals, and the two ends of each horizontal roller table 1 are all rotatably supported on the outer sides of the furnace body 2; when the present invention works, it is located The glass to be processed 7 of different shapes and areas on the horizontal roller table 1 separates the heating space into a relatively closed and disconnected upper space 21 and a lower space 22;

[0028] Several upper high-temperature fans 41 and lower high-temperature fans 42 are arranged in the upper space 21 and the lower space 22 respectively. The driving device 43 (such as an electric motor or an internal combusti...

Abstract

The invention provides a heating method of a heating furnace for glass tempering; air in the heating furnace is driven by a high temperature blower fan to flow circularly so as to take away heat generated by an electric heating element; the air is pressurized and injected onto a surface of glass to be processed; and thus heating in a convection heating manner is realized; the heat generated by the electric heating element is also transmitted to the surface of the glass to be processed through radiation heating; during the heating process, the glass to be processed is heated in a main manner of convection heating; when the glass to be processed is heated to a temperature near a glass softening temperature, the glass to be processed is heated in a main manner of radiation heating till the glass to be processed reaches a temperature at which tempering can be completed. With the heating method, using the characteristic that convection heating is faster than radiation heating, the temperature of the glass to be processed is increased quickly; and with the characteristic that matrix radiation heating of a device allows regional temperature adjustment, each part of the glass to be processed can be heated to the temperature at which glass tempering can be completed.

Description

technical field [0001] The invention relates to a heating method for a heating furnace used for tempering glass. Background technique [0002] The process of glass tempering requires that the temperature of different parts in the furnace cavity of the heating furnace can be individually controlled, so that each part of the glass to be processed can be accurately heated to the temperature at which the glass can be tempered. [0003] At present, the more efficient glass heating furnaces widely used in glass tempering, especially coated glass tempering, are derived from utility model patent 200920006859.8. The temperature of the hot air ejected from the convection tube of the heating furnace cannot be controlled separately in different parts of the furnace. When the temperature of different parts in the furnace needs to be controlled, only by adjusting the temperature of the electric heating element in each independent heating area, the electric heating This is achieved by the...
