PRODUCT PARAMETERS
Description
1200°C High-Temperature Car-Bottom Furnace
This 1200°C high-temperature car-bottom furnace utilizes high-temperature alloy resistance strips for heating, with heating elements positioned on the two side walls and the bottom. The equipment is equipped with a pull-out loading hearth, a 7-inch touchscreen, and a 30-segment programmable temperature control system, making it suitable for the high-temperature heat treatment of large, heavy workpieces.
Product Features
- High-Temperature Alloy Resistance Strip Heating
The heating elements consist of high-temperature alloy resistance strips, positioned along the sides and bottom of the furnace chamber. Dedicated temperature control points are provided to meet the requirements for high-temperature heat treatment at temperatures up to 1200°C.
- Pull-Out Bogie-Hearth Loading System
The loading platform (trolley) can be manually pulled out of the furnace, facilitating the loading and unloading of large or heavy items. The trolley is constructed using a combination of high-purity lightweight alumina insulation material and high-alumina refractory bricks, ensuring both effective thermal insulation and high load-bearing capacity.
- Efficient Thermal Insulation and Dual-Layer Air Cooling
The furnace lining consists of folded zirconium-containing alumina fiber modules. The furnace body features a dual-layer, air-cooled design, with circulating cooling air used to lower the temperature of the furnace shell and the conductive components of the heating elements.
- Intelligent Programmed Temperature Control and Comprehensive Protection
Equipped with a 7-inch touchscreen and a 30-segment programmable controller, the system allows for the configuration of heating, holding, cooling, and cyclic processes. It also incorporates multiple safety features, including protection against over-temperature, over-current, over-voltage, and phase loss, as well as current feedback monitoring and a soft-start function.

| Furnace Body Structure | The electric furnace body adopts an internationally advanced air-cooled double-layer structure. An effective air-cooled guide baffle enables overall cold air circulation in the furnace shell, ultimately cooling the heating element conductive plates before discharging out of the furnace body, avoiding high-temperature oxidation of the heating element conductive plates; ensuring a good working environment |

| Protection | An integrated modular control unit is adopted for accurate control precision, and dual-loop control and dual-loop protection are designed, featuring protection against overshoot, over-regulation, under-regulation, broken thermocouple, phase loss, overvoltage, overcurrent, overtemperature, current feedback, soft start, etc. |
| Control | Closed-loop technology is adopted for thyristor module trigger control, with phase-shift triggering control mode. Output voltage, current, or power can be continuously adjusted, featuring constant voltage, constant current, or constant power characteristics. The current loop is the inner loop, and the voltage loop is the outer loop. When a load is suddenly applied or the load current exceeds the current limiting value, the output current of the voltage regulator is limited within the rated current range to ensure normal operation of the output and the voltage regulator. At the same time, the voltage loop also participates in regulation, so that the output current of the voltage regulator is limited within the rated current range, maintaining constant output current and voltage under the premise of sufficient adjustment margin. This protects the heating elements from impact of excessive current and voltage, achieving safe and reliable control effects and control precision |
