Glass Furnace Exit Monitoring

Applications

Apr 29,2026

System Introduction

The HIRDA-HT high-temperature resistant infrared thermal imaging temperature measurement and analysis system is specially designed for the glass furnace exit, which can work normally in a high-temperature environment of up to 500℃. It consists of an infrared thermal imaging core, an infrared lens, a high-temperature resistant water-air cooled metal protective cover, a thermal imager control cabinet and client software. It solves the following pain points: molten glass radiation and high-temperature airflow interference make it difficult to obtain accurate temperature, prolonged exposure to extreme heat accelerates equipment failure, and manual spot checks fail to detect temperature fluctuations at the furnace exit in time.

Product features

1. It features all-weather passive thermal imaging capability and can operate over a wide range of ambient temperatures.

2. It adopts a high frame rate design, enabling observation of fast-moving targets.

3. It utilizes a self-developed temperature measurement correction algorithm to achieve accurate temperature measurement.

4. It outputs full-stream lossless 16-bit temperature data and provides client software along with an SDK development kit, facilitating secondary development and system integration for users to carry out customized temperature analysis of the measured target.

Equipment Value

Common issues during the production of automotive tempered glass:

1. Non-uniform tempering and substandard particle size

2. Glass bending, warping, and optical distortion

3. Scratches and stress marks

4. Edge cracking and center burst points

Effects of the infrared thermal imaging system:

The infrared thermal imaging system monitors the temperature at the furnace outlet to reduce power, increase temperature, adjust air volume, and change line speed. This ensures temperature uniformity, improves yield, and reduces energy consumption.

Actual economic benefits brought by the infrared thermal imaging system:

1. Automotive-grade raw glass + processing cost: approximately 80~200 RMB per piece (side window / rear windshield / sunroof)

Assuming a production line outputs 3,000 pieces of glass per day, and the yield increases by 1%–3%, the daily loss reduction is 2,400~18,000 RMB. Calculated on 300 days per year → annual savings of 720,000~5.4 million RMB.

2. The system enables more uniform furnace temperature, eliminating the need for excessively high temperatures to maintain production, thereby reducing energy consumption. Energy consumption decreases by 3%–8% per line. Monthly electricity/gas costs are approximately 200,000~400,000 RMB → monthly savings of 10,000~30,000 RMB → annual savings of 150,000~350,000 RMB.
