What is the Difference Between Batch Vacuum Furnace and Continuous Vacuum Furnace?
Batch Vacuum Furnaces
It's designed for many thermal processes, the electrically heated batch vacuum furnace is available in a multitude of configurations. The most basic configurations are the front and top-loading single chamber styles where work is loaded into and out from the same door. These are designed for high-temperature applications such as brazing, annealing, carburizing, hardening, tempering and are supplied with graphite or ceramic insulation packages. Evacuation systems include rough pumps, boosters, and diffusion pumps when required. Being modular in design, independent quench chambers may be added to the basic heating chamber. The quenching mediums may be gas, pressurized gas, and/or oil. Isolation of the modules (temperature and vacuum level) may be accomplished with an internal vacuum door.
Batch Atmosphere Furnaces Thermal Processing Systems manufactures, installs, and commissions a full range of batch atmosphere products. Our product line covers a wide range of different processes including tempering, annealing, nitrocarburizing, nitriding, stress relieving, normalizing, steam treating, and inert atmosphere processing. These products are highly energy-efficient and can be gas-fired or electrically heated. They are available in standard configurations and sizes or can be custom designed. We can provide the ideal product to process your specific parts based upon your loading method, process, temperature, and atmosphere requirements.
Continuous Vacuum Furnace
The continuous vacuum furnace essentially transforms the batch vacuum furnace into a straight through furnace. Work is no longer processed into and out from the same side – rather work is loaded into the entry side and unloaded from the exit side of the furnace. Modules consist of load/evacuation chambers, preheat and high heat chambers, multiple heat position chambers, and quench (oil and/or pressurized gas) chambers. Small batches are therefore indexed in a continuous fashion making this style furnace highly productive in processes that range from annealing, brazing, carburizing, sintering, to hardening. With the continuous vacuum furnace, the heat chamber typically remains hot and under vacuum making for a highly efficient and pure system.
Continuous Atmosphere Furnaces Thermal Processing Systems manufactures, installs and commissions a wide range of continuous atmosphere products which include mesh belt, pusher, and roller hearth furnaces. Our product line covers a wide range of different processes including sintering, brazing, annealing, glass-to-metal sealing, carburizing, carbonitriding, hardening, inert atmosphere processing, normalizing, stress relieving, tempering, and drying. These products are highly energy efficient, and can be gas-fired or electrically heated. They are available in standard configurations and sizes or can be custom designed. We can provide the ideal product to process your specific parts based upon your process, temperature, atmosphere, and throughput requirements.
Heating Methods
There are several types of heating methods, including:
Resistance Heating
Resistance heaters such as metal heaters, silicon carbide (SiC), molybdenum, tungsten, and carbon are commonly used.
Temperature control is achieved by inserting a thermocouple into the heater and managing the heater temperature, thereby controlling the temperature inside the furnace.
01
Induction Heating
This is the most widely used method of electric heating.
A high-frequency magnetic field is created by an external coil, inducing an electric current in the object to be heated, and heating the surface of the object. It is an efficient method.
02
Electron Beam Heating
This is a heating method that irradiates an electron beam onto the object to be heated to partially generate high temperature.
03
Laser Beam Heating
Similar to electron beam heating, this method irradiates the object to be heated with a laser beam to partially generate high temperature.
04
Direct Current Heating
This is a heating method in which electric current is passed directly through the object to be heated, generating self-heating, and is also known as "Joule heating".
05
Corresponding to the characteristics of each heating method, almost all heat treatments such as quenching, tempering, nitriding, carburizing quenching, and bright heat treatment can be performed.
Common Types of Furnaces Used in Heat Treatment Processes
Batch Furnaces
Batch furnaces can process different metal workpieces for long periods of time. The work charge with these furnaces remains stationary, ensuring that interactions with changes in their atmosphere can be carried out in near-equilibrium conditions. Varying types of batch furnaces can be used by manufacturers. These types include bell furnaces, box furnaces, fluidised bed furnaces, pit furnaces, and salt pot furnaces. Integral quench furnaces, in particular, are common batch furnaces that can perform case hardening to metal workpieces.
Continuous Furnaces
Continuous furnaces, alternatively, often work by allowing the workpieces to move in specific manners while the environment surrounding them changes. Some common types of continuous furnaces that manufacturers take advantage of include mesh belt furnaces, rotary drum furnaces, humpback furnaces, vacuum furnaces, and walking beam furnaces. One common type of continuous furnace today is the pusher furnace. This type of continuous furnace can be effective in carrying out hardening, stress relieving, annealing, and carburising.
Atmosphere Furnaces
Atmosphere furnaces take advantage of a protective atmosphere to surround the workpieces whenever they are heated and cooled. When picking the volume of the protective atmosphere, manufacturers have to consider the type and size of the furnace, the presence or absence of doors or curtains, the environment, size, loading, and nature of the work. By picking the right atmosphere furnaces, the success of a heat treatment process can be achieved. The atmospheres used in heat treatment, after all, intend to protect the workpieces from surface reactions and allow their surfaces to change or be chemically active or reactive.
Vacuum Furnaces
Vacuum furnaces can be designed based on the size of the workpiece, the pressure and temperature to be attained, and the medium that will be used in cooling the workpieces. And during heat treatment, they should be able to control the temperature and vacuum level optimally to process workpieces optimally. Some parts of vacuum furnaces are the vessel, the pumping system, the hot zone, and the cooling system. These furnaces can be effective in carrying out annealing, sintering, brazing, and other similar heat treatment processes. Many more furnaces can be used in heat treatment processes. However, the furnaces listed above are some of the most common elements used by manufacturers today.

FAQ
Q: 1. What is a non-continuous furnace?
A non-continuous furnace is a closed process machine best suited for inert atmosphere or cleanroom applications. Once the heating chamber has been sealed, heat treatment can be performed without risk of cross-contamination.
In batch furnace heating, items are grouped in racks or baskets for treatment. Rather than being automatically fed into the heating chamber, articles need to be removed from the production line for grouping. This requires more work, but this is offset by batch furnaces' ease of operation (and maintenance).
Continuous furnaces are more complex (and therefore more expensive) than batch furnaces. As such, they require frequent maintenance. In continuous furnaces, temperature uniformity is critical such that temperatures cannot be easily altered. A non-continuous furnace allows for flexibility of formulation - free of cross-contamination - in specialized applications in aerospace, automotive, petrochemicals, optics, and other industries.
