Application of Raytek infrared thermometer in the glass industry

Raytek company, which has 35 years of experience in manufacturing infrared thermometer for industrial environment, is committed to providing high-quality products for the glass industry. These products are especially designed for monitoring and controlling every part of the glass production line. The products include non-contact infrared scanner, intelligent probe temperature measurement system (probe and display device), and can be customized according to the needs of customer glass production

raytek infrared thermometer (or probe) provides fast, accurate and non-contact temperature measurement. Real time monitoring enables the manufacturing of glass and secondary processed glass to obtain the following benefits:

● improve output and yield ● improve process control ● improve product consistency

● improve product quality ● reduce downtime

Raytek infrared probe is used to measure the temperature of furnaces, glass in furnaces, melting pools, regenerators, clarifiers, material channels, droplets, molds, float lines and annealing furnaces, as well as cooling areas and coating areas. Effective temperature measurements reflect the conditions of the heating or cooling process, such as whether the regenerator has become too hot or too cold, whether the temperature in the bath and annealing furnace area is correct, and so on. Careful inspection of the melting state to the cooling process can ensure that the glass can maintain its characteristics in every manufacturing process

Raytek temperature solution


there are two types of furnaces, one is horizontal flame furnace, the other is horseshoe flame furnace. The direction of the flame in the furnace changes periodically, and the regenerator can heat the combustion supporting air, so as to improve the fuel efficiency. The lattice bricks in one side of the regenerator are heated by the hot gas discharged from the furnace. When the lattice bricks rise to an appropriate temperature, the flame direction will be changed, and the regenerator on this side will heat the combustion supporting air entering the furnace, so as to operate alternately

in order to ensure the best operation efficiency, Raytek thermometer is installed on the top and bottom of each regenerator. Unqualified components cannot be installed in the use part of the system, and the reversing of air and flame can be started at the best time. Using ray can also reduce energy consumption. Tek probe monitors the corrosion of lattice bricks and refractory materials, which is very important for arranging hot repair and cold repair as planned. It can avoid the passive situation of huge expenditure caused by emergency shutdown. Raytek portable thermometer is regularly used to detect the outside of the furnace and regenerator to find out the hot spots caused by the corrosion of refractory bricks, so as to prevent the leakage of liquid glass

measure the temperature at the small furnace arch and bridge wall to maximize the service life of refractory materials there. Raytek probe can accurately locate and measure the temperature of each brick through ADDA, a DDS and a ddc3 address decoding, which can avoid the false measurement caused by furnace flame

flat glass

in the production of flat glass, the temperature monitoring of each process is very critical. Incorrect temperature or rapid temperature change in the annealing furnace will cause uneven expansion and contraction of glass, resulting in poor annealing. The annealing furnace has multiple temperature control zones. In the tin bath part, the probe is installed on each location to ensure the accurate glass temperature. The probe with thermojackettm air-cooled protective sleeve is installed in each area to maintain the flatness of the glass surface and the consistency of the edge to edge transverse temperature. Then, the MP50 line scanner is installed between the tin bath and the annealing furnace. The specific part of the annealing furnace and its outlet are used to scan the temperature across each point on the width of the glass. Any lack of flame on the surface, such as cracking, local thinning or thickening, or the temperature difference of the surrounding glass caused by the cooling of the bubble, will display color images in real time on the computer screen

bottles, cans and containers

molten glass flows from the furnace to one or more material channels (depending on the production scale), where the glass should maintain a uniform temperature. At the end of the material channel, the material drops fall into the mold and are formed by blowing (with compressed air) or by pressing with the core mold and the forming mold

it is very important to maintain the appropriate temperature of molten glass in the chute to ensure the appropriate uniformity of glass at the outlet. When the droplet is formed and leaves the bowl mouth, it must have a suitable viscosity (a 1-degree temperature change will cause a 1% change in viscosity). The infrared optical fiber probe is installed along the material path to monitor and control the temperature of each section

the temperature of each control area in the annealing furnace must be strictly monitored and controlled to maintain the annealing quality of products. If the product is too hot when leaving the annealing furnace, it will be damaged in the subsequent process or crack when encountering external cold air. If the products in the annealing furnace are cooled too fast, it will also cause cracking or damage. If the cold end surface treatment is applied to bottles and containers, the products at the outlet also need to be kept at an appropriate temperature

installing probes in each section of the annealing furnace can accurately monitor and control the cooling process of products and the surface treatment of the cold end. This can achieve better quality control and less waste

glass fiber

there are two main methods to manufacture glass fiber: centrifugal glass wool and jet glass wool. The temperature of each section of the material path is monitored and controlled by the infrared optical fiber probe, so that the engineer can keep the glass entering the fiber former (rotating head) at the best temperature (or viscosity). The temperature of the fiber former is monitored by an infrared probe to maintain its compatibility with the fiber. 2. Our party provides lifelong protection service wire for the equipment, and can prevent the blockage of the discharge hole of the fiber former. Plugging the hole can make the glass "slag ball" enter the final product, that is, the thermal insulation material. The hot glass slag ball can still ignite the lining paper after the thermal insulation material is made for a few days

in the curing furnace, it must be controlled at a suitable temperature, otherwise the curing agent will not cure well. If the backing paper and/or aluminum foil are bonded to the glass fiber, the fiber must be at an accurate temperature to ensure good adhesion between the materials

the probe is installed along the conveyor belt to monitor the temperature at the inlet and outlet of the curing furnace. With this temperature feedback, the engineer can monitor and adjust the temperature of the furnace and curing furnace. If it is automatic adjustment, the probe signal can be connected to the control room. The MP50 line scanner is installed behind the curing furnace to monitor the uniformity of curing and detect dangerous slag balls hidden in the whole width. The infrared probe is distributed in the material path, conveyor belt and curing furnace, which can make the whole production line more efficient and maintain the high quality of products

other processes

other processes, including the processing of automobile windshield glass, can benefit from the use of Raytek infrared probe. MP50 line scanner or themalert probe is used in the heating section and forming section to monitor and control its temperature. In the production of laminated safety glass for vehicles and buildings
