Description
1400℃ Car Bottom Furnace
The 1400℃ car bottom furnace is an industrial electric furnace suitable for heat treatment of large workpieces. It belongs to the Car Bottom Furnace/Bogie Hearth Furnace type. The equipment adopts a movable trolley structure, facilitating the loading and unloading of heavy or large workpieces. It is widely used in the metallurgy, machinery manufacturing, mold making, and new materials industries.
This equipment, combined with a touchscreen intelligent control system, achieves high-precision temperature control and automated operation, making it an ideal device for heat treatment and sintering processes of medium to large workpieces.
Product Features (Car Bottom Furnace)
- Large-capacity furnace chamber, 2-ton load capacity
This car bottom furnace has a furnace chamber size of 1500mm × 1000mm × 1000mm (depth × width × height), with a volume of 1.5 cubic meters and a loading platform load capacity of 2 tons. Suitable for heat treatment and sintering processes of large workpieces and batch products, it is an ideal piece of equipment for mass production.
- Electric loading platform inlet and outlet, convenient operation
The loading platform uses an electric inlet and outlet system with a 2-ton load capacity, ensuring stable and reliable operation. The refractory material between the furnace opening and the loading platform is stepped and cross-sealed, with angles on both the top and bottom of the refractory material. The opening angle of the loading platform increases, and the closing angle gradually decreases, ensuring a good seal.
- Peripheral heating
The heating elements are U-shaped silicon carbide rods of equal diameter, evenly distributed around the furnace chamber to form a three-dimensional heating field. The silicon carbide heating element is a non-metallic high-temperature electric heating element made primarily of high-purity α-SiC. It features rapid heating, high thermal efficiency, long lifespan, resistance to deformation at high temperatures, and ease of installation, operation, and maintenance. Temperatures can reach 1500℃.
- Precise Temperature Control, Uniform Furnace Temperature
It employs a platinum-rhodium S thermocouple (temperature range 0-1600℃), with a temperature control accuracy of ±1℃ and furnace temperature uniformity of ±5℃. The heating rate can be freely adjusted from 1℃/h to 15℃/min to meet the heating speed requirements of different materials and processes.
- 7-inch Touchscreen Centralized Control
Equipped with a touchscreen, it allows for temperature curve setting and features an intuitive and user-friendly interface. It uses an intelligent temperature controller that supports multiple adjustment methods, including standard PID, AI-based APID, or MPT, and possesses self-tuning and self-learning functions, exhibiting excellent control characteristics with no overshoot or undershoot.
