Abstract
A crystal-growing furnace system with an emergent pressure-release arrangement includes an isolated chamber and a furnace upper body. The top board is provided with an opening and three first guides, and the furnace upper body with a lower opening and three second guides, wherein the lower opening of the furnace upper body covers, correspondingly, on the opening of the top board. In case a crystal-growing furnace, combined oppositely by the furnace upper body and the furnace lower body, has an over-high internal pressure, the pressure will overcome the weight of, and lift up the furnace upper body. At this moment, the furnace upper body will slightly move upward and away from enclosing the furnace lower body, so that the over-high internal pressure in the furnace will be released immediately to prevent the furnace from being exploded and from resulting in public accidents.
