Customized atmosphere furnaces have the advantages of higher efficiency, more uniform material heat treatment, more energy saving and environmental protection, and customizable configuration according to needs. Sometimes, when a larger processing capacity atmosphere furnace is needed, it is necessary to customize the furnace size atmosphere furnace. So, what aspects should be paid attention to before customization? Let's take a look below!

1. Clarify application requirements and process requirements
Temperature range and accuracy
Determine the maximum working temperature based on material characteristics (such as metal heat treatment requiring 1200 ℃ or above, ceramic sintering may require 1600 ℃ or above).
The requirement for temperature uniformity needs to be clearly defined (such as ± 5 ℃ or higher accuracy) to ensure consistent temperature in all areas of the furnace.

Atmosphere type and control
Determine the required atmosphere type (such as inert gas, reducing gas, vacuum, etc.) and evaluate the gas purity requirements (such as 99.999% high-purity nitrogen).
Multiple atmosphere switching or mixed atmosphere control needs to be supported to meet complex process requirements.

Furnace size and shape
Customize furnace length, width, and height based on workpiece dimensions to ensure uniform heating.
Consider special shapes (such as circles, squares) or irregular furnace designs to accommodate special workpieces.

2. Evaluate equipment performance and reliability
Heating elements and insulation materials
Heating elements should be made of high temperature resistant and anti-oxidation materials (such as silicon molybdenum rods, silicon carbon rods, resistance wires, etc.), and their lifespan and maintenance costs should be evaluated.
Insulation materials need to have low thermal conductivity and high temperature resistance (such as ceramic fibers, alumina fibers, etc.) to reduce heat loss.

Sealing and vacuum degree
The sealing structure of the furnace body should be made of high-strength and high-temperature resistant materials (such as stainless steel and carbon steel), and equipped with vacuum sealing rings or welded seals.
The vacuum system needs to meet the vacuum degree required by the process (such as 10 ^ -3 Pa or higher), and be equipped with vacuum pumps, vacuum gauges, and other equipment.

Control System and Automation
The temperature control system needs to support multi-stage program heating, constant temperature control, and have PID regulation function to ensure temperature stability.
The atmosphere control system needs to support precise control of gas flow and pressure, and be equipped with gas analyzers (such as oxygen content analyzers) to monitor atmosphere composition.

3. Consider safety and environmental performance
Safety protection measures
The furnace body needs to be equipped with safety devices such as over temperature protection, leakage protection, and overvoltage protection to ensure safe operation.
An emergency stop button and fault alarm system need to be installed to promptly handle abnormal situations.

Environmental protection and energy-saving design
The furnace body needs to use efficient insulation materials to reduce heat loss and energy consumption.
It is necessary to equip exhaust gas treatment devices (such as catalytic combustion devices, adsorption devices) to treat harmful gases generated during the process.

4. Assess the customization capability and after-sales service of suppliers
Customization capability
Suppliers need to have rich customization experience and be able to provide customized designs for furnace size, heating method, atmosphere control, and other aspects according to user needs.
Detailed technical solutions and drawings are required to ensure that the equipment meets the user's process requirements.

After sales service and technical support
Suppliers are required to provide comprehensive services such as equipment installation and commissioning, operation training, maintenance, and upkeep.
A rapid response mechanism needs to be established to promptly handle equipment failures and user feedback.

5. Comprehensive cost and cost-effectiveness
Equipment prices and operating costs
It is necessary to compare the equipment prices of different suppliers and evaluate their cost-effectiveness.
It is necessary to consider the operating costs of the equipment (such as energy consumption, gas consumption, maintenance costs, etc.) and choose a plan with lower long-term costs.
