Erosion of the furnace wall in the trichlorosilane synthesis furnace
Thread Content
Recently, the furnace walls of several trichlorosilane synthesis furnaces have started to wear out, with the wear occurring at a 45° angle above the silicon powder feeding port. Has anyone encountered this issue before? Is there any way to solve this? Thank you!
In this area, it can only be repaired by making the repair section thicker
It seems to be useful for ceramic pipelines, but then again, how high must the pressure be, or how thin must the pipe walls be?
I haven’t encountered it yet; just make sure the silicon powder feed port isn’t facing the cooling tube, as that can easily damage the furnace core
A wear-resistant coating can be sprayed on; we use one of good quality.
Which company are you from? Specializing in the production of trichloro-methane?
We haven’t encountered that either. It seems that your problem is caused by an increase in silicon powder levels; in other words, you need to monitor the pressure inside the furnace to understand the situation and reduce the pressure of hydrogen chloride gas entering the furnace
