Generally, the heat treatment furnace of protective gas should be equipped with devices to ensure its operation, and also to ensure its good curved sealing. So what are the necessary devices to ensure the operation of heat treatment furnace as a popular industrial furnace?
The heat treatment furnace is usually a cylindrical furnace. The shell of the furnace is usually made of section steel and welded with steel plate. Most of the workpieces are hung with special hangers inside or outside the furnace mouth, and the control area is usually 1-1.5 times of a diameter.
The controllable atmosphere box to ensure the operation of heat treatment furnace is usually divided into three parts: front chamber, furnace and cooling tank. The front chamber is mainly composed of a sealed space welded by section steel and steel plate, and the lower edge is connected with the cold groove, and the upper side is the air cooling chamber with water-cooled wall. In the middle, there is a material rack which passes through the workpiece track and up and down lifting, and is operated by the cylinder on the top. When the workpiece descends, it enters into the cooling tank for rapid cooling or isothermal quenching. When it rises, the workpiece is slowly cooled in the upper atmosphere. The furnace is located at the back of the front chamber and separated by a furnace door in the middle, and the furnace will be opened through the upper cylinder when feeding and discharging.
The above is to share with you to ensure the operation of heat treatment furnace necessary device knowledge points, hope to let you more in-depth understanding of the heat treatment furnace.
