The principle of electromagnetic brake for trolley furnace

2023-12-06 10:30

The trolley frame is formed by welding steel, ensuring its rigidity without deformation under full load. The interior is built with refractory bricks, while the easily colliding and load-bearing parts are built with heavy bricks to enhance the strength of the furnace lining structure. The walking of the trolley adopts a self-propelled structure, which is driven by the reducer drive sprocket to walk on the track. The sealing of the trolley adopts an automatic labyrinth structure and soft contact double sealing. The trolley enters the furnace through the action of a cam and a roller slope, and is automatically lifted for sealing. When the trolley is driven out, the sealing groove automatically falls down, and the sealing sand in the sealing groove does not need to be added frequently after being filled.
The trolley is driven and the furnace door is lifted and lowered by electric control, equipped with electromagnetic brakes to prevent inertia from hitting the furnace body. The interlocking control automatically cuts off the heating element and restores the power supply of the trolley's walking mechanism when the furnace door is slightly opened. After the furnace door is closed in place, the power supply to the trolley walking mechanism is automatically cut off, and the heating element power supply is restored to the trolley furnace at the same time.

Cause analysis and solution measures of short circuit problem in tempering furnace

Many years ago, our company purchased a multi-purpose furnace heat treatment production line. After it was put into use, the wiring terminals behind the tempering furnace and the tempering furnace shell had multiple short circuits, which caused inconvenience to maintenance. At the same time, smoke still emanates from the fan motor shaft above the tempering furnace, the furnace door, and the lead terminals behind the furnace during the early stages of the tempering process.
