Double head trolley type resistance furnace characteristics
Features of double head trolley type resistance furnace:
1. The electric furnace is equipped with a hot air circulation device to make the furnace temperature uniform and the workpiece heated evenly;
2. The electric furnace has large loading capacity and high productivity, which is suitable for tempering, quenching and preheating of various types of parts; 3. The furnace lining adopts full fiber structure, which improves the thermal insulation performance of the furnace body, saves energy and reduces production cost; 4. The electric furnace has convenient charging and good operation conditions;
5. The furnace door is of front and back double opening type, two charging trolleys work in turn, saving energy and improving efficiency, easy to operate;
6. The electric furnace is equipped with interlock protection device, which can prevent faults and accidents caused by misoperation;
7. No pollution, good environmental protection benefits.
The shell of this series of electric furnace is welded with steel plate and section steel. The bottom of double head trolley resistance furnace body is connected with trolley light rail. Users do not need to install the foundation, but only put it on the flat cement ground for use.
The lining of the double head trolley type resistance furnace adopts the full fiber structure, which can save about 50% energy compared with the brick furnace. The high-quality long fiber thorn blanket is used as the raw material, and the special equipment is used to make 300 × 300 × 300 specification modules, and a certain amount of compression is reserved in the processing process, so as to ensure that after the completion of masonry, each ceramic fiber block expands in different directions, so that the modules are mutually squeezed into a seamless whole The utility model has good heat insulation and heat preservation effect, and the construction of the product is convenient and quick. Compared with other products, the double head trolley type resistance furnace has the advantages of low heat conduction, low heat capacity, excellent corrosion performance, excellent thermal stability, thermal shock resistance and thermal insulation, and the anchor is set on the cold surface of the furnace body, which improves the high temperature strength of the fiber.
The heating element of double head trolley type resistance furnace is made of high temperature resistance alloy wire wound into strip and spiral shape, which are respectively hung and placed on the furnace side, furnace door, back wall and trolley silk brick, and fixed with high aluminum porcelain nails, safe and simple.
The double head trolley type resistance furnace trolley is equipped with a high-strength and high-temperature resistant cast steel furnace bottom plate for carrying workpieces. In order to prevent the oxide skin generated after the workpiece is heated from falling into the surrounding of the heating element through the gap between the furnace bottom plate and causing damage to the heating element, the plug-in contact is adopted at the contact between the furnace bottom plate and the furnace body. In order to ensure normal use, it is necessary to blow the oxide skin under the bottom plate of the trolley furnace frequently. Generally, blow it once a week. When blowing, lift the bottom plate of the furnace. Use compressed air to blow the oxide skin in the resistance wire slot clean. Pay attention to prevent the oxide skin from causing short circuit in the furnace wire.
The double head trolley type resistance furnace door device is composed of furnace door, furnace door lifting mechanism and furnace door pressing device. The furnace door shell is welded by section steel and plate to form a solid frame structure, which is overlaid with fire-resistant fiber pressing module, requiring good heat preservation performance and light weight. The lifting device of furnace door is electric device, mainly composed of furnace door frame, furnace door lifting beam, reducer, chain wheel, transmission shaft and bearing. The lifting of furnace door drives the lifting of furnace door through the positive and negative transmission on reducer. The furnace door lifting reducer is also equipped with a brake device, which can effectively prevent the furnace door from displacement in the lifting process. The furnace door pressing device adopts the domestic advanced spring type lever pressing structure. When the furnace needs to be lifted, the self weight of the furnace door will automatically loosen the furnace door through the lever, and then move it out horizontally for a certain distance to rise. When the furnace door falls in place, the elastic force of the spring will move the furnace door horizontally through the lever to the pressing and sealing state. The pressing device of this structure makes the furnace door friction free when it is up and down It has the characteristics of good safety performance and long use mission of double head trolley resistance furnace.
