USES:

Mainly used for tempering, quenching, preheating and other heat treatment of various metal parts and materials.

Equipment structure features:

1. The electric furnace is provided with a hot air circulation device to make the furnace temperature uniform and the workpiece heated uniformly; 2. Large loading capacity and high productivity, suitable for tempering, quenching and preheating of various parts; 3. The furnace lining adopts the whole fiber structure to improve the thermal insulation performance of the furnace body, save energy and reduce production cost; 4. The electric furnace is convenient for charging royal materials and good operation conditions; 5. The furnace door is double-open before and after, and two charging carts work alternately, saving energy and improving efficiency, making it easy to operate; 6. The electric furnace is equipped with interlocking protection device, which can prevent faults and accidents caused by misoperation; 7. No environmental pollution, good environmental benefit.

The shell of this series electric furnace is welded with steel plate and section steel. The bottom of the furnace body is integrated with the trolley light rail. The user does not need to install the foundation.

Relative brick lining adopts full fiber structure, furnace energy saving 50%, adopt high quality long fiber blanket as raw material, using special equipment made of 300 * 300 * 300 specifications of the module, and the machining process with compressed volume, in order to make sure the module in the building has been completed, each ceramic fiber expansion in different directions, make the whole of the crowded into each other without gap between modules, good heat insulation, heat preservation effect, and the product construction convenient and quick. Compared with other products, it has the advantages of low thermal conductivity, low thermal capacity, excellent corrosion performance, excellent thermal stability, thermal shock resistance and thermal insulation, and the anchoring part is set on the cold side of the furnace, which improves the high-temperature resistance strength of the fiber.

Heating elements are made of ribbon and spiral wound with high temperature resistance alloy wire, which are hung and placed on the furnace side, furnace door, back wall and trolley shelf brick respectively, and fixed with high aluminum porcelain nail.

High strength and high temperature resistant cast steel furnace bottom plate is laid on the platform for bearing work pieces. In order to prevent the oxide skin generated after the workpiece heating falling into the gap between the furnace bottom plate and the heating element and causing damage to the heating element, the furnace bottom plate and the furnace body contact place adopts the insertion type contact. In order to ensure normal use, it is necessary to frequently purge the oxide skin under the bottom plate of the trolley furnace. Generally, purge the bottom plate once a week, lift the furnace bottom plate and purge the oxide skin chip in the resistance wire groove with compressed air, so as to prevent the oxidation pickup from causing short circuit in the furnace wire.

The furnace door device is composed of the furnace door, the furnace door lifting mechanism and the furnace door pressing device. The shell of furnace door is welded by section steel and plate into a firm frame structure, and is made of laminated refractory fiber pressing module, which requires good insulation performance and light weight. The lifting device of the furnace door adopts electric device, which is mainly composed of the furnace door frame, the furnace door lifting beam, reducer, sprocket, transmission shaft and bearing, etc. The lifting of the furnace door drives the lifting of the furnace door through the positive and negative transmission on the reducer. The furnace door lifting reducer is also equipped with brake device, which can effectively prevent the furnace door from displacement in the lifting process. Oven door clamp device adopts domestic advanced spring loaded lever clamp structure, when need to increase the stove, the oven door automatically by the oven door lever will loosen the weight, and level up after removed from a distance, when drop in place under the oven door, again by the spring of the elastic pressure closely through lever move the standard oven door seal state, this kind of structure of the compaction device on the oven door, under without rubbing brush, have the characteristics of good performance, USES mission long.
