Abstract
The invention discloses a bell-type gas nitriding furnace comprising a heating furnace body. The heating furnace body is mainly composed of a main furnace, a base and a bottom furnace door. The heating furnace body is provided with a support. A vertical cubic heating area is arranged on the top of the support. The heating area is located inside the main furnace. The base is provided with a fixed rail. A gas pump is arranged on the top of the main furnace. The gas pump is connected with a communicating pipeline. The top and the bottom inside the main furnace are both connected with convective fans. The bottom furnace door is arranged inside the fixed rail. The top of the bottom furnace door is connected with a material platform. The bottom furnace door is driven by the motor. The bell-type gas nitriding furnace is in vertical-structure design, the heat treatment process at the low-temperature section has the best temperature uniformity in a convective heating manner, and meanwhile the temperature rising speed of a workpiece is improved; and the nitriding atmosphere is forced to circulate in a work area through the convective fans, and therefore nitriding is more uniform.
