Machine Introduction

The Vertical Glass Tempering Furnace (vertical type and hanging type) is mainly used for tempering flat glass. The glass is heated, tempered, and cooled in a vertical state. Compared with the horizontal roller table tempering furnace, this equipment greatly saves floor space. It is suitable for most plant layouts. The glass is heated and tempered vertically, and the intelligent heating system ensures uniform temperature control. The glass does not touch any roller, ensuring the surface quality of the glass. The surface quality of the glass which is defect-free after tempering. It is characterized by low investment and no defects on the glass surface.

This vertical glass tempering furnace is mainly composed of four parts: heating section, forming quenching section, circular (or linear) transportation track, and electrical control system. The heating section of the furnace adopts new air convection technology and a special structure designed in the United States, so that the glass temperature has good consistency and stability during heating, It also ensures the uniform distribution of high-temperature air convection. Each temperature controller has over-temperature protection.

The quenching section is composed of a high-pressure blower, air knife system, a cooling and driving system. The air knives in the quenching section are distributed vertically, and the cooling air is precisely controlled to be evenly applied to the surface of the glass. The distance between the air nozzle and the glass can be automatically adjusted to achieve the best glass quality. The glass product is flat, has no spots, no deformation, 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. This equipment has a human-computer interaction interface that is convenient and simple to operate. It is characterized by excellent quality, stable performance, sturdiness and durability, and easy maintenance.
