Industrial All Fiber Pit Furnace
Jiangsu Jiuding Industrial Furnaces Technology Co., Ltd. is one of the most experienced manufacturers and suppliers of industrial all fiber pit furnace in China, also supports customized service. Welcome to wholesale high-grade industrial all fiber pit furnace for sale here from our factory. Quality products and reasonable price are available.
Product Description
As an All fiber pit furnace manufacturer, we produce vertical industrial furnaces for batch heating and metal heat treatment. The furnace uses a deep chamber design and a high-purity ceramic fiber lining.
The fiber modules help reduce heat stored in the furnace lining and limit heat loss during operation. This design is suitable for production processes that require controlled heating and repeated heating cycles.
We select the chamber diameter, depth and heating configuration according to the workpiece dimensions, loading weight and required process temperature.
Working Principle
The All fiber pit furnace for heat treatment uses electric resistance elements to generate heat. Heat transfers to the workpieces through radiation and other heat transfer processes inside the chamber.
A temperature control system regulates the heating process according to the selected settings or process curve. The actual temperature distribution depends on the furnace design, heating zones, load arrangement and operating conditions.
Key Features
Ceramic fiber lining: High-purity ceramic fiber modules provide the main insulation layer.
Lower thermal mass: The lining design helps reduce heat stored in the furnace structure.
Resistance strip heating: Widened resistance strips provide the heat source.
Automatic temperature control: The system regulates heating according to the selected process settings.
Heating zone configuration: The number of zones can be matched to the chamber design.
Safety interlock: The furnace cover position is linked to the heating control circuit.
Flexible chamber dimensions: Diameter and depth can be designed around the workpieces.
Batch operation: Suitable for production schedules based on separate heating cycles.
Product Structure and Materials
The All fiber pit furnace with ceramic fiber lining consists of several main assemblies:
Furnace shell: Supports the lining and heating components.
Ceramic fiber insulation: High-purity, high-pressure fiber modules form the main insulating layer.
Resistance heating system: Widened resistance strips generate heat inside the furnace.
Furnace cover and lifting mechanism: Provide access for loading and unloading workpieces.
Temperature control cabinet: Monitors and regulates the heating process.
Safety interlock system: Cuts off the relevant heating control power when the cover is opened.
The shell, lining arrangement, heating zones and control configuration can be adjusted to suit the required furnace dimensions and heat treatment process.
