Components of trolley furnace

1. Furnace lining adopts full-fiber structure, which saves about 40% energy compared with brick furnace. It uses high-quality long-fiber thorn blanket as raw material and is made with equipment, and a certain amount of compression is left in the processing process to ensure that the module is completed after the masonry is completed. , Each ceramic fiber block expands in different directions, so that the modules are squeezed into a whole without gaps, achieving a perfect heat storage effect, and the product is convenient and quick to construct, and can be directly fixed on the stainless steel anchor nail of the furnace shell steel plate .

2. The heating elements of the trolley furnace are made of high-temperature resistance alloy wire wound into ribbons and spirals, respectively hung on the furnace side, furnace door, back wall and placed on the trolley wire bricks, and fixed with high-alumina porcelain nails. Safe and concise.

3. The trolley furnace is equipped with a pressure-resistant and high-temperature cast steel furnace bottom plate to support the workpiece. In order to prevent the oxide scale generated after the workpiece is heated from falling into the heating element through the gap between the furnace bottom plate and causing damage to the heating element, the contact between the furnace bottom plate and the furnace body adopts plug-in contact.

4. The furnace door device is composed of the furnace door, the furnace door lifting mechanism and the furnace door pressing device. The furnace door shell is welded by section steel and plate to form a firm frame structure, and the interior is laminated with refractory fiber pressing modules, which require good heat preservation performance and light weight. The lifting device of the furnace door adopts an electric device, which is mainly composed of a furnace door frame, a furnace door lifting beam, a reducer, a sprocket, a transmission shaft, and a bearing. The furnace door lifting is driven by the positive and negative transmission on the reducer to drive the furnace door up and down. .

5. The frame of the trolley furnace is formed by welding section steel, and its rigidity is guaranteed not to be deformed under full load. The interior is built with refractory bricks, and the easy-to-collision parts and load-bearing parts are built with heavy bricks to enhance the structural strength of the furnace lining.

6. ​​Flip hydraulic mechanism: The hydraulic power flip mechanism is combined with a motor, plunger pump, solenoid valve, hydraulic cylinder, etc., controlled by an electric button in the control cabinet, and installed with an anti-overturn device to ensure safe and convenient use.

7. Electrical control system: The temperature control adopts intelligent microcomputer program to control the temperature. It is equipped with a recorder to record the complete process curve and can alarm over temperature; the operation adopts buttons and light display to realize the in and out of the trolley furnace, the heating element on and off, and The furnace door lifts and other actions are controlled, and there is an interlocking device. When the furnace door is raised or closed to a certain position, the trolley can move, which is safe and reliable.
