Problems solved by technology
[0005] Since there is only one furnace wire circuit in the heating unit area, once the furnace wire circuit is damaged and the overall circuit breaks, the heating unit area will not work, the temperature in this area cannot reach the set temperature, and there will be a large temperature difference with the nearby heating unit area, thus making the glass Uneven heating affects the quality of tempered glass, making the yield of the product extremely low, and even making it impossible to continue production
The traditional solution is to cool down and shut down the furnace for maintenance, which greatly reduces production efficiency and greatly increases production costs

The invention relates to a temperature control furnace structure for a glass toughening furnace, and relates to the glass toughening furnace field. The structure comprises a furnace loop (1), a furnace loop (2), a temperature measuring component (3), a PLC (10), controlled silicon (4) and controlled silicon (5). The invention is characterized in that two isolated furnace loops are positioned in a heating area, thus, when a single furnace is damaged for non working, the other furnace heating loop can increase heating powder to ensure that the temperature in the heating area also can reach the setting temperature, thereby ensuring that the glass is evenly heated, ensuring the product quality and improving the production efficiency.
Description
technical field [0001] The invention relates to a glass tempering furnace, which is especially suitable for the temperature control furnace wire structure of the glass tempering furnace. Background technique [0002] The temperature control furnace wire structure of the glass tempering furnace in the prior art is composed of a furnace wire circuit, a temperature measuring element, a PLC, and a thyristor. The total heating area is composed of multiple heating unit areas, and each heating unit area is composed of a single furnace wire circuit. The furnace wires in the heating unit area are connected in parallel according to the design power, and the temperature signal in the heating unit area measured by the temperature measuring element is fed back to the PLC. After the PID operation in the PLC, an analog value is output to the thyristor. Change the current to make the furnace wire circuit reach the set power, thereby adjusting the temperature of the entire heating unit area...
