Machine Introduction

The Small Size Glass Tempering Furnace adopts industry-leading small-size glass tempering technology. With years of experience, the smallest tempered glass size can reach 30x30mm. We improved the traditional tempering furnace structure design and process design, and successfully solved various technical problems in the production of small-size glass, such as glass deviation, particle size/weight, loading rate limitation, temperature control, etc. This tempering furnace is suitable for all kinds of small-size glass products and is suitable for industrial applications such as household appliances, lamps, electronics, optics, and instruments.

This small size glass tempering furnace is mainly composed of six parts: loading area, heating area, quenching area, unloading area, blower system, and electrical control system. The glass is placed in the loading section and then removed in the unloading section after tempering. The working principle is that when the temperature in the furnace reaches a certain level, the glass is driven into the furnace, heated on the ceramic roller, and moved back and forth. When the temperature of the glass has exceeded the tempering temperature but has not been completely softened, the glass is quickly entered into the quenching section with cold air for quenching and cooling, and the flat tempered glass is obtained when this process is completed.

The heating section in the furnace adopts new air convection technology and a special structure designed in the United States. The new air convection system is equipped with a high-efficiency convection device so that the glass temperature has good consistency and stability during heating. Ensure high-temperature air convection and uniform temperature distribution. Convection can be adjusted in a wide range and is easy to control. This tempering furnace uses ceramic rollers with excellent linearity, roundness, and heating deformation. The deformation of the glass during heating is almost 0%. Furnace heating control mode: intelligent module + programmable control PLC.

The quenching section is composed of high-pressure blowers (or compressed air), a through-type air knife, a cooling and driving system. The quenching and cooling air knives make the cooling air evenly applied to the upper and lower surfaces of the glass. The distance between the air knife and the glass can be automatically adjusted to achieve the best glass quality. The glass product is flat, with no spots, no marks, and its optical properties are close to the original glass.

Products comply with ANSI Z97.1, EN 12150-1:2000, GB15763.2-2005, GB/T9963, GB/T9656, JIS R 3206, and other tempering standards. The operation and maintenance of this glass tempering furnace are convenient and simple. It is characterized by high production efficiency, excellent quality, high performance, durability, and low energy consumption. The equipment adopts improved passing-through technology, which not only guarantees the quality of tempering but also achieves the purpose of energy saving. It is well received by glass processors and fabricators.
