How to choose a customized well type crucible furnace?

Well crucible furnace is a common industrial heating equipment, named after its well shaped furnace body and crucible placed inside for carrying materials. It is widely used in metal heat treatment, melting, sintering and other fields. So what are the aspects to pay attention to when customizing a well crucible furnace? Let’s take a look below!

Functional requirement
Clarify the heating purpose: Determine whether the well furnace is used for high-temperature firing of ceramics and metal materials, or for heat treatment of bar and long shaft parts (such as quenching, tempering, annealing, etc.). Different purposes have different requirements for the performance and design of the furnace.
Consider atmosphere control: If inert gases (such as nitrogen or argon) or reducing gases (such as hydrogen) need to be introduced during the experiment or production process, a well furnace with corresponding atmosphere control functions should be selected, ensuring that it has a gas flow control system, vacuum pump interface, and sealing flange.

Technical Parameter
Temperature range: Select the appropriate temperature range based on the materials and processes required for processing. For example, general high-temperature firing may require reaching 1200 ℃ or even higher, and it is necessary to ensure that the maximum temperature and long-term operating temperature of the furnace can meet the requirements.
Temperature control accuracy: Temperature control accuracy directly affects the quality of experiments or production. Generally, temperature control accuracy is required to be ≤ ± 1 ℃. For some processes that require higher temperature, higher accuracy may be required.
Heating rate: Choose the appropriate heating rate according to the process requirements. Some processes may require rapid heating, while others require slow heating.
Furnace size: Select the appropriate furnace size based on the size of the sample or workpiece to ensure that the sample or workpiece can be smoothly placed in the furnace and there is sufficient space for heating and processing.

Structure Design
Furnace structure: Consider whether the furnace body adopts a double-layer shell structure or other structures. The double-layer shell structure usually has better insulation performance and energy-saving effect. At the same time, attention should be paid to the material of the furnace body, and materials that are resistant to high temperatures and corrosion should be selected.
Furnace door design: The design of the furnace door should be convenient for taking and placing samples and workpieces, such as using an upward opening furnace door structure. In addition, the furnace door should have good sealing performance to prevent heat loss and atmosphere leakage.
Crucible design: The material of the crucible should be selected based on the properties of the material being processed, such as materials with good thermal conductivity and conductivity (such as copper, oxygen free copper, etc.). At the same time, the size, shape, and structure of the crucible should be considered to ensure that it can meet the requirements of experiments or production.

Safety and reliability
Protection mechanism: Ensure that the furnace has multiple protection mechanisms, such as over temperature alarm, leakage protection, disconnection protection, door opening and power-off function, etc., to ensure the safety of operators and the normal operation of equipment.
Heating element lifespan: The heating element is one of the core components of the furnace, and its lifespan directly affects the operating cost and maintenance cycle of the furnace. Choose a furnace with longer heating element lifespan.

Brand and after-sales service
Brand selection: Priority should be given to well reputed well furnaces, which typically have more mature technology, more reliable quality, and more comprehensive after-sales service.
After sales service: Understand the manufacturer’s after-sales service content, including warranty period, repair response time, spare parts supply, etc. Choose a manufacturer with good after-sales service so that any problems encountered during use can be promptly resolved.
