RT4 series of high-temperature car type resistance furnace is our patent product, the Chinese exclusive patent, Patent No.: 200520096582.4. The resistance furnace with the most advanced international synchronization of high-temperature car type resistance furnace technology has become the important products of China's exports to international markets and participate in international competition. To export high-temperature car type resistance furnace only factory exclusive. I plant trolley resistance furnace production line and mass production, the largest domestic production. 

 Purposes: 
 RT4 series of high-temperature car type resistance furnace is mainly used for high-manganese steel liner, high chromium and high manganese steel castings, ductile iron, roller, ball, pump, hammer crusher, resistant liner hardening, solid solution, normalizing, annealing and heat treatment of the various mechanical parts. Also be used for sintering, calcination, precision formwork roasting. 

 Structure description: 
 Furnace: the high-temperature car type resistance furnace adopts export trolley furnace structure, the most advanced international car electric furnace standards. Housing is made of steel plate and steel welded into a fixed structure, trolley track with the integration of even the rail structure, an electric furnace and furnace outside the orbit factory trolley furnace with the overall structure, and debug qualified, the user only needs to prepare the foundation pit sink 100mm, secondary cement grout to seal the track and sleepers, overloaded electric furnace trolley running vibration force transmitted is absorbed in the soil, to ensure the electric furnace of the car long-term trouble-free operation. 

 Lining: In order to reduce power consumption, lower outer wall temperature, improve the insulation performance, furnace using high-intensity ultra-lightweight beads saving bricks, play a dual role of both refractory and insulation. Put silk brick factory exclusive production of the interior angle bend 20 degrees to let go of the wire brick, Never lose your resistance wire. Insulation layer with a new wave stacked high purity aluminum silicate fiber blanket is a typical energy-saving furnace lining. In order to prevent the workers loading heap partial impact high strength and high-pressure collision brick lining, the furnace mouth, installed in the chamber surrounding the lower part of the surrounding heavy put a hit brick, effective protection of the lining. Electric furnace roof of a large trolley full-fiber multi-layer vertical flat-top structure of the stacked aluminum silicate insulation effect. 

 Loading trolley: loading trolley overloaded structure, trolley combination of steel beam of the bucket structure, smooth operation when overloaded trolley masonry brick high-strength insulation, high temperature put silk brick surface of the trolley heavy high-pressure compression brick. Trolley surface labyrinth refractory masonry. Sealing between the electric furnace trolley and furnace uses our unique design, popular in the international l-bit auto-sand seal groove sealing mechanism can effectively reduce the heat loss of the furnace to improve temperature uniformity. When the car drove into the furnace, the seal groove is automatically lifted, the gap between the trolley and the furnace sealed, the seal groove when the car left the furnace, automatic drop reset, not produce friction losses. Installed before the trolley run independently of the power box, built-in motor, reducer, brake, fully rely on the independent operation of its own power. Taiwan car equipped with a chromium manganese nitrogen heat-resistant steel furnace floor or 1200 ° C silicon carbide furnace base plate carrying the workpiece. 

 Door: trolley furnace door with electric lift, rely on the chain drive. Door seal with the trajectory weight pressed, the door all-fiber composite structure. The door lifting scroll wheel scroll up and down the rail to achieve, both to ensure a consistent seal between the furnace close the door when the door to ensure the friction damage masonry, will not open the door and the trolley movement are provided by the motor through the worm gear reducer, chain drive, and equipped with electromagnetic brake to make the appropriate adjustments. 

 Heating elements: heating element materials for the International General OCr27Al7Mo2 high temperature resistance alloy wire or resistance band, sub-variety of power, pitch temperature Busi design. According to the distribution of different kcal, rational arrangement of the side wall, door, hearth and electric furnace back wall, a large trolley furnace temperature uniformity. Supporting multiple high-power high-temperature car electric furnace automatic temperature control cabinet, multi-zone heating, automatic temperature control and run the door trolley. 

 Temperature control mode: the high temperature trolley furnace temperature control system with automatic temperature control of the most advanced microcomputer technology curve, is the world's most advanced high-precision energy-saving temperature control technology, and ruled out human error, according to user needs heat treatment technology curve automatically change the power level, the output energy-saving power not only save energy but also reduces the fluctuations in the temperature inertia, so that the desired heat treatment process curve in the practical application of high precision execution. Each microcomputer program automatic temperature control, power cabinet installed six sets of high-power board SCR can be automatic or manual control and adjust the power 0-100% stepless output, not transferred between the microcomputer and the thyristor power circuit, avoiding the hidden faults, and high reliability. According to the heat treatment process needs, arbitrarily set each heating rate (ie hourly heating degrees), each holding temperature (ie, to the desired temperature insulation), each holding time (ie, to the desired temperature when the insulation long) can be set to eight out technology curve. Temperature Accuracy ± 1 ℃.
