Product Definition
Bell type heat treatment furnace is a batch furnace with a movable bell shaped cover. You lower the hood over a stationary base where the workpieces sit. That forms an enclosed heating chamber. You control the temperature and the atmosphere inside.
Working Principle
The whole idea is that the hood moves. The outer cover goes up and down. Here's how you run it. You put your workpieces on a fixed base. Then you lower the heating hood down over them. Now you've got a closed heating space.
Why do it this way? A few reasons. First, you can adjust the furnace space depending on how big your workpieces are. Second, you can have multiple bases and move one hood between them. That improves utilization – one hood, several bases. Third, the sealing is good. You can control the atmosphere inside without leaks.
Features
Full fiber furnace structure. Saves energy. Compared to a brick lined resistance furnace of the same size, you save thirty to thirty eight percent on power. Heats up twice as fast too.
Lightweight furnace body. You can move it by hand crank or electric drive. Lift the hood, expose the base, load or unload. Simple.
Because the hood moves, maintenance is easier. You can get to things. The furnace lasts longer.
One hood, multiple bases. You buy one heating unit and several bases. Move the hood from base to base. Saves investment. Increases productivity.
Applications
Bell type heat treatment furnaces are common in non-ferrous metal processing and machinery manufacturing. Especially for annealing copper and aluminum. The temperature field is uniform and you can control the atmosphere. Product quality stays consistent.
Also used for bright annealing of precision welded or seamless metal tubes.
