Application of short-wave infrared heating in electroplating process

Infrared heating tubes are basically characterized by infrared rays. It is actually a tubular heater that uses the working principle of infrared rays. Generally speaking, its performance is relatively stable, its quality is high, its thermal efficiency is high, and its power density is relatively high, so it can help products heat up quickly and help enterprises save time and electricity with high efficiency. Relatively speaking, this heating technology can be called a more energy-efficient heating method in the market, and it can also save electricity and energy, helping enterprises reduce overall operating costs. Also because of its energy-saving heating characteristics, it has been listed as a key promotion project in my country, and it has also achieved very good economic benefits at present.

Especially in this era of countries vigorously advocating energy conservation, emission reduction and green industry, the emergence of infrared heating tubes is very in line with the current market needs, helping industries reduce energy consumption and playing a role in environmental protection.

The infrared heating tube does not need to be dried in an open or sealed environment, because the drying material has a high absorption efficiency for infrared rays, while ensuring the drying quality and efficiency. In addition, short wave, medium wave and other wavelengths can match the absorption spectrum of most materials very well, and can effectively meet the needs of workpieces made of different materials, and can tailor-made heating plans for customers based on the performance of the heated object.

Short-wave and medium-wave radiation heating use a simple and direct heat transfer method that is more energy-saving. The feature of "inside-to-outside" simultaneous heating can improve the quality of the workpiece and is suitable for most heated objects. Therefore, infrared heating tubes have the advantages of excellent thermal efficiency, resource saving, simple installation, cleanliness, and high cost performance.

Customer case

Customer's problem: The customer is an electroplating factory. The previous method was to use commercial steam to dry electroplated parts by hot air convection. Commercial energy consumption is high, costs are high and commercial steam supply is unstable, affecting production efficiency;

After receiving the request, we quickly made a plan for the customer, customized short-wave infrared heating lamps according to the infrared absorption wavelength of the material, and installed a lamp arrangement every 30cm at the end of the drying room.

After switching to infrared heating, the following effects are achieved:

●Space saving - Originally, using hot air required a 45m long production line, but replacing infrared lamps only requires a 10m long production line.

●Time saving - When using hot air, the drying effect can be achieved in 15 minutes at a speed of 3m/min.

Using infrared lamps, under normal production line speed, if the 60KW is turned on to 3m/min, there will be local moisture at about 10m. If the full power is turned on, the drying effect is very good. If the moisture content is less than 50%, the production requirements can be met.

●Energy saving - The original use of hot air consumes 0.5 tons of steam per hour and is unstable; there are 33 infrared lamps, each 2.5KW, and the total power is 82.5KW. Stable, clean and efficient.

●Cost saving - the original use of hot air steam was 430 yuan/ton. You need to pay 215 yuan per hour, and if the infrared is turned on at full power, it is 80 yuan/hour.
