Abstract:
1. A heat treating furnace for a gas reaction comprising: an outer body having a first side and a second side corresponding to said first side, said first side being provided with a first gate door capable of being opened, said second side being provided with a second gate door capable of being opened, a first gas-tight structure arranged inside said first gate door, a second gas-tight structure arranged inside said second gate door; an inner body having an outer wall and an inner wall, being spaced and fixed inside said outer body, thereby forming a gas circulation chamber between said outer wall and said outer body and a reaction chamber between said inner wall, said inner body having a third side and a fourth side corresponding to said third side, and when said first gate door is being closed, said first gas-tight structure being hermetically sealed with said third side and said second gas-tight structure being hermetically sealed with said fourth side, thereby either of said gas circulation chamber and said reaction chamber being an independent gas-tight chamber; a heating mechanism being fixed and contacted with said outer wall of said inner body; and a gas supplying mechanism set outside said outer body being connected with one of said side of outer body and one of said side of inner body by utilizing a plurality of gas pipes such as to control the supply of a first gas into said gas circulation chamber and the supply of a second gas into said reaction chamber; and a controller provided outside said outer body for controlling the supply amount of said first gas into said gas circulation chamber and the supply amount said second gas into said reaction chamber through said gas supplying mechanism, thereby forming a first pressure (P
