Is there any that involves silver plating on the inner wall of the reduction furnace?

Have any of you managed to apply silver to the inner wall of a reverberatory furnace? What was the result?

Just turn the stick over and you’ll see how powerful it is........................;P
It’s not that great; the silver transfer method works well for a few uses at most. After that, due to the adhesion of amorphous silicon on it, its effectiveness is lost and it becomes like an ordinary furnace. Generally, growth is faster in the first few batches, but after that it’s the same.
Yes. Features of the Silver Reduction Furnace DH-202: 1. This furnace uses conveyor belts for baking; it is made of SUS 310 material that can withstand temperatures up to 1000 ℃. It features five-stage temperature control, with RKC meters used for the second, third, fourth, and fifth stages. The speed can be adjusted as needed. Additionally, it is equipped with an alarm switch and a buzzer – an alarm is triggered and the machine stops automatically when the material reaches the end of its path. 2. Operation and maintenance of this furnace are simple, requiring no manual intervention, thus saving time and increasing efficiency. Specifications: Dimensions: 6060 (length) × 850 (width) × 1330 (height) mm. Weight: Approximately 360 kilograms. Production capacity: 2000 pieces per 8 hours, based on 5 φ – 10 φ ceramic tiles or tubes. Power requirements: 220V/380V, 1P/3P, 50/60 Hz, 1/2HP, 23.5KW. Temperature range: 0 – 800 ℃. Function: It reduces the silver paste (which is silver oxide) printed on ceramic tiles or tubes to a silver-white color through heating at 800 ℃.
What is the cost of silver plating? Is it electroless plating or electroplating? First, mechanical polishing is carried out, followed by electrolytic polishing; then a protective layer resistant to high temperatures and oxidation is applied through electroplating. This approach ensures lasting energy savings and excellent results.
Friend, is the above your experience with using a reduction furnace for silver plating? Are there any good ways to remove the amorphous substances attached to the surface? Thanks for the advice!
For gold plating and silver plating, it is necessary to analyze the costs and benefits in comparison, depending on what one’s priorities are
I think silver plating and gold plating are fine for pilot tests in the laboratory, but when it comes to practical use on a large scale, the cost of just gold and silver alone is extremely high. Moreover, the market situation for silicon isn’t very good right now!
The reason for silver plating is that silver is a material in nature that can reflect far-infrared radiation at 100%, which allows for a reduction in heat loss of around 20%. However, silver has poor oxidation resistance; when the coating is thin, it turns into silver oxide, which does not reflect infrared radiation well, after only a short time. The finish is similar to that of silver plating, and it also has excellent oxidation resistance. However, maintenance is relatively difficult; coatings generally contain capillary pores. When the reduction furnace is started, hydrogen chloride gas absorbs moisture from the air, forming hydrochloric acid. Corrosion of the stainless steel substrate through the gold plating causes the plating to flake off. The cost of gold plating is lower than that of silver plating. This is because there are multiple plating steps: nickel plating -- copper plating -- silver plating. The method I use is brush plating.
