The main operating temperature of the high-temperature trolley furnace exceeds 1000 degrees Celsius, and due to its unique structural features, it is widely used for heating, annealing, normalizing, quenching, surface hardening, stress-relieving annealing, and other heat treatment processes for large carbon and alloy steel parts, and has received unanimous praise from industry professionals. Today, the editor of Star Ding will talk about the structural composition and characteristics of the high-temperature trolley furnace.
　　

Section 1: Structure of the High-Temperature Trolley Furnace

1. Furnace lining

　　
The高温 car-bottom furnace shell is焊接from steel plates and shaped steel, utilizing either ultra-lightweight vacuum spherical energy-saving bricks with high-purity fiber composite lining or full ceramic fiber insulating lining. The furnace mouth is lined with heavy-duty collision-resistant bricks, while the car-bottom surface is lined with heavy-duty high-alumina bricks.
　　

Door furnace

　　
The lifting and lowering of the furnace door is primarily achieved through the rolling wheel's movement along the guide rail, ensuring a tight seal between the door and the furnace body when closed, while also preventing friction and damage to the masonry during opening. The movement of both the furnace door and the trolley is powered by an electric motor, which is connected through a reducer and a chain drive. Additionally, the installed electromagnetic brake allows for appropriate adjustments.

3. Trolley

　　
The furnace body and trolley chamber are constructed using labyrinth-type refractory materials. Moreover, they incorporate a self-acting sealing mechanism through advanced technology to minimize heat loss in the trolley furnace, thereby improving the uniformity of the furnace temperature. The bottom of the furnace body is integrated with the trolley light rail, allowing for easy use on a flat concrete surface without the need for installation by the user, offering great convenience.
　　

4. Furnace bottom plate

　　
The furnace bottom plate of the high-temperature trolley furnace is made of heat-resistant chrome-manganese-nitrogen steel or 1200°C silicon carbide to support the workpieces.
　　

5. Thermal Element

　　
The material used for the heating element is the general OCr27Al7Mo2 resistance wire or resistance strip. The anti-drop slanting 20° wire support brick is used for the heating element, with a maximum operating temperature of 1440°C.
　　

6. Temperature Control System

　　
Star鼎 Furnaces offers specially designedHigh-Temperature Trolley FurnaceThe computerized three or multi-zone temperature control cabinets, equipped with multiple microcomputers or multi-zones, individually control the heating for each zone with high-precision automatic temperature control and door trolley operation. The cabinets feature multiple microcomputers and a multi-channel color screen paperless automatic recorder, primarily for automatic control and recording of furnace temperatures. The cabinets achieve high-precision non-contact 8-segment program control of the trolley furnace's temperature through microcomputer fuzzy logic and PID calculations, allowing the user-defined high-precision heat treatment process temperature program curve to run. This realizes the automation of the heat treatment process, making operation simple and efficient, with temperature control accuracy up to ±1°C.
　　

High-Precision Trolley Furnace Design

　　
To achieve uniform heating of the furnace, the traveling grate furnace employs a three-zone heating system and arranges heating elements according to the even temperature weaving method. To compensate for the heat loss at the furnace mouth, the arrangement ranges of the heating elements in zones 1-3 differ. This ensures that the high-temperature traveling grate furnace maintains consistent three-zone even temperatures during the heating and保温 processes, with an even temperature accuracy of ±3-5°C.
　　

Section Two: Features of the High-Temperature Carriage Furnace

　　
The traveling of the trolley furnace and the lifting of the furnace door are both electrically operated, offering convenient operation and reduced labor intensity.
　　
2. The furnace lining utilizes a new composite lining, which accumulates less heat, heats uniformly, and achieves energy savings of over 20%.
　　
The high-temperature trolley furnace features a special sealing structure between the furnace door and panel, resulting in minimal heat and atmosphere loss, and a relatively stable furnace gas.
　　
4. Customizable to meet diverse user needs, the trolley can be designed with hydraulic or mechanical tilt options, and can also include a circulating fan and air guidance system.
　　
5. The high-temperature trolley furnace utilizes a specially designed high-temperature, high-resistance electric heating alloy as the heating element, offering a longer service life.
　　
6. The automatic sealing device for the trolley and furnace body is innovative, well-designed, practical, and safe.
　　
7. Employing effective sealing measures, low-oxidation equipment, and anti-seepage and anti-fracture electrical heating elements ensures the achievement of low-oxidation objectives.
　　
The above covers all the details of the structural composition and characteristics of the high-temperature trolley furnace. From the above introduction, it can be understood that the high-temperature trolley furnace is mainly composed of the furnace body and lining, furnace door, trolley, furnace bottom plate, heating elements, temperature control system, and high-precision trolley furnace design, and it boasts features such as easy operation, energy-saving, stable furnace gas, customizable to meet specific needs, and a long service life. The high-temperature trolley furnaces produced by Luoyang Xingding Kiln Furnace Co., Ltd. are of excellent quality, diverse specifications, and meet customer requirements.
