Trolley furnace should be equipped with appropriate heating elements
In order to prevent the role of the furnace atmosphere on the trolley furnace heating elements, as well as carbon black deposition caused by short circuit, the trolley furnace heating elements should be used plate-shaped anti-carburizing electric heating elements (low power supply of large current), or try to isolate the atmosphere, the use of radiation tube heating elements.
There are explosion-proof devices. The trolley furnace is usually equipped with explosion-proof holes on the furnace or on the top of the front and rear Chambers. In addition, there are also devices, such as one-way valve, stop valve, flame backcheck valve, pressure measuring device and alarm on the pipeline.
The purpose of setting up a ventilator in the furnace is to make the atmosphere and temperature uniform. The fan shall be water cooled and sealed. For smaller box-type furnaces, an axial fan can be installed at the top of the furnace without the need for a diversion device. The fan is installed in the center of the trolley furnace slightly against the back wall, and the impeller is as close to the workpiece as possible. Proper consideration has been given to the opening of air intakes, various vent positions, and outlet of exhaust pipes. In general, in the need for air pressure adjustment place are equipped with water seal device.
