Can the tube furnace for experiment achieve the effect of the muffle furnace?
In order to achieve the effect of the muffle furnace for experiment use, do I need to add flanges at both ends of the tube furnace? Do you want to add a snorkel? Or add a flange without a vent pipe?
During use, a tube furnace can be used instead of a high-temperature muffle furnace, but it must be ensured that air enters the tube. The two ends of the flange are not closed, and the heat convection can allow air to enter.
In addition, the refractory cotton is plugged at both ends to prevent the large difference between the temperature in the tube and the furnace caused by the large air flow, and it can also prevent the trouble caused by gas expansion and contraction.
