Double trolley type electric resistance furnace

Double bogie hearth resistance furnace referred to as double trolley furnace or to open trolley furnace, trolley furnace with double for all metal parts and materials, tempering, quenching and preheating and heat treatment.

Double head type trolley resistance furnace casing has steel plate and steel welding, the bottom of the furnace is connected with the light rail. The user does not need to be installed.

Double bogie hearth resistance furnace lining using all fiber structure, relative brick furnace energy-saving 50% by high-quality long fiber needling blanket as raw material, the use of special equipment made of 300 x 300 x 300 specifications of the module, and leave a certain amount of compression, in order to ensure the module in masonry has been completed, each of the ceramic fiber block in different directions expansion, module between mutual squeeze into a seamless whole to good heat insulation, thermal insulation effect, and the product construction is convenient in the process. And other products compared to the advantages of low thermal conductivity, low heat capacity, excellent corrosion resistance, excellent thermal stability and thermal shock, thermal insulation and anchor set on the stove body cold, improve the fiber of high temperature strength.

Double bogie hearth resistance furnace heating element with high temperature resistance alloy wire is wound into a ribbon and spirally were hanging, placed on the side of the furnace, door, after wall and trolley put silk brick, and high aluminum porcelain nail fixed safety concise.

High strength and high temperature resistant cast steel furnace bottom plate is laid on the trolley of the resistance furnace of the double head type car to load the workpiece. In order to prevent the oxidation of the oxide skin from the workpiece heated, the heat element is caused by the gap between the furnace and the bottom of the furnace. The furnace bottom and the furnace body are in contact with the insert type. In order to ensure the normal use and need the often blow sweep car bottom furnace bottom oxide, a week blowing a sweep, blow sweep the furnace bottom of the lift, with compressed air resistance wire groove oxide debris clean, purge, pay attention to prevent oxidation pickup in the furnace wire caused by short circuit.

Double type trolley resistance furnace door device by the door, door and door lifting mechanism composed of clamping device. Door shell by steel and sheet metal welding and firm frame structure, with refractory fiber repression module stack shop, requires the heat insulation performance is good, light weight and so on. Furnace door lifting device uses an electric device, is mainly composed of a door frame, a furnace door lifting beam, a speed reducer, a chain wheel, a transmission shaft and the bearing part, the furnace door lifting through deceleration device on the positive and negative transmission to drive the door lifting. The reducer is equipped with a braking device can effectively prevent the lifting door, door displacement in the lifting process. Door clamping device adopts domestic advanced spring-loaded lever pressing structure, when the need to upgrade the stove, the weight of the door through the lever will door unlocked automatically, after rising and removed from a distance, when the door in place, by the elastic force of the spring by leverage the furnace door level move to press the sealing state. Such a structure, the clamping device to the door, when no friction generated, has good safety performance, long mission.

Characteristics of resistance furnace for double - head car:

1, double trolley furnace with hot air circulation device makes the furnace temperature uniformity, the workpiece is heated evenly;

 

2, double trolley furnace loading, high productivity, applicable to all types of mechanical parts tempering, quenching, preheating;

 

3, double trolley furnace lining using the fiber structure, improve the insulation performance of the furnace body, save energy, reduce the production cost;

 

4, double head car furnace is convenient, operation condition is good;

 

5, the door is only 2 before and after the double type, loading trolley work alternately, save energy and improve efficiency, convenient operation;

 

6, double head car furnace with chain protection device, can prevent the accident and accident caused by misuse;

 

7, no pollution, good environmental protection.
