[0002] The single crystal furnace main heater calcining equipment is a supporting equipment for heater processing. The pulling method is currently a common method for growing single crystals. Its working principle is to heat and melt the raw materials that constitute the crystal in a crucible, connect a seed crystal to the surface of the melt and pull the melt. Under controlled conditions, the atoms or molecules of the seed crystal and the melt are continuously rearranged at the interface, and a single crystal is grown as it gradually solidifies as the temperature drops. This process is mainly to ensure the stability of its heater and reduce the instability of crystal pulling. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of single crystal furnace main heater calcining equipment.

There is no fixed equipment for calcination at present, and most calcinations are carried out with shutdown equipment, which is not only inefficient but also difficult to observe the real-time dynamics of calcination. For this reason, we propose a single crystal furnace main heater calcination equipment. Utility Model Content
