Description of the Equipment
1.1 Brief introduction
The furnace includes loading table, heating, quenching and cooling section, unloading table, and control system. It is used to manufacture flat tempered glass for furniture, home appliance, architecture glass, etc.
1.2 Loading Table
The loading table is composed of rubber-covered rollers and Kevlar rope. When the glass is put onto the rollers, the glass will be conveyed automatically to the entrance of the furnace where it will be in ready-to-enter-furnace position and the rollers stop moving. It will send the glass into the furnace once the computer control system gives enter command.
1.3 Heating Section
The structure of the heating section is of a double-layer box type covered with thermos-insulation material. Inside the section there is a conveyor system with high temperature resistant ceramic rollers. Heating elements and radiation plates are installed on the upper layer and lower layer of this section. The upper layer radiation plate is special heat resistant and anti-corrosion cast material. The heating element is of an integrated part with spiral type resistance erected on ceramic part, it's easy to replace. When the glass is going to enter the furnace, the front door of the heating section opens the rolls of the loading table and heating section move at the same time. When the glass is in the furnace, the front door will close and the glass on the rollers will be moved back and forth at the distance calculated by the controlling system automatically, so that the glass will be heated evenly. The upper section can be lifted up for maintenance. The heating elements are in matrix layout.
1.4 Flat Quenching/Cooling Section
The alloy sections and steel sheet is cold riveted to avoid deformation of heat welding, ensure effectively the entire flatness at air face of quench. Rational nozzle aperture and arrangement of air hole guarantee the glass even cooling. The upper and lower quenches are combined with linkage and individual drives, which can actually control the rational height for air nozzle of quenches. Matched with balance control of upper and lower air amount, the top and bottom of the glasses can reach to optimum heat radiation, so as to ensure the flatness of tempering glass.
1.5 Forced convection heating system
Balance tube made by air tube of convection heating system with leptospira model. The convection air comes from compressor to spray hot air into the surface of the soft coat Low-E glass; under the production working process, the heating chamber is combed with both forced convection and radiation. In any case when you expect to process Low glass(both soft and hard coat), you could switch on the compressor control and when you only intend to process clear float glass you can only adopt radiation for processing.
1.6 Unloading Table
The unloading table is the similar as the loading table. When the glass is transported to the end of the conveyor, the rollers will stop, and the glass can be taken away by hand, or by robot, if there is available at the customer's factory.
