What is the difference between a trolley furnace and a regular muffle furnace?

There are significant differences between trolley furnace and ordinary muffle furnace in multiple aspects, mainly reflected in structural characteristics, application fields, heating methods, and performance.
Structural characteristics
Trolley furnace:
The furnace body of a trolley furnace generally consists of two main parts: a fixed heating chamber and a movable furnace bottom on the trolley. The furnace is fixed and the furnace bottom can move along the track, making it easy to load and unload workpieces outside the furnace.
The interior of the furnace is usually insulated with high refractory materials to maintain uniform temperature. The furnace door is designed with a sealing device to reduce heat loss.
The trolley furnace is also equipped with a transmission system, such as motor drive and gearbox drive, to drive the trolley in and out of the furnace.
Ordinary muffle furnace (taking box type muffle furnace as an example):
The structure is relatively simple, usually consisting of a furnace body, heating elements, temperature control system, etc.
The furnace space is small and suitable for processes such as heat treatment, firing, and melting of small workpieces.
The furnace door design also emphasizes sealing, but the overall structure is more compact.
application area
Trolley furnace:
Widely used in industries such as metallurgy, machinery manufacturing, and building materials. Mainly used for heating, annealing, normalizing, tempering and other processes of metal materials, as well as heat treatment of mechanical parts.
In the building materials industry, it can also be used for curing and solidifying concrete, as well as for firing ceramic products and other processes.
Ordinary muffle furnace:
The application scope is also relatively wide, but it focuses more on processes such as heat treatment, firing, and melting of small workpieces and samples.
It is also applied in laboratories, research institutions and other places, such as in drug testing, medical sample pretreatment, water quality analysis, environmental analysis and other fields.
Heating method
Trolley furnace:
Usually, electric heating methods such as resistance wires, electric heating tubes, etc. are used as heating elements.
The heating elements are distributed at the bottom of the furnace and trolley, providing uniform heating.
Ordinary muffle furnace:
There are various heating methods, which may include arc heating, plasma combustion heating, etc. (but electric heating is also a common method).
The arrangement and heating method of heating elements vary depending on the specific model and purpose.
Performance Performance
Trolley furnace:
It has the advantages of fast heating speed, uniform temperature, energy saving and environmental protection.
Equipped with safety protection devices such as over temperature alarm, power-off protection, etc., to ensure the safe operation of the equipment.
Suitable for large-scale production and processes with high requirements for heat treatment.
Ordinary muffle furnace:
The performance varies depending on the model and purpose, but overall it may focus more on fine processing of small workpieces and samples.
The temperature control accuracy and uniformity are also relatively high, but they may not be as suitable for large-scale production as trolley furnaces.
In summary, there are significant differences between the trolley furnace and the ordinary muffle furnace in terms of structural characteristics, application fields, heating methods, and performance. When choosing which equipment to use, it is necessary to consider the specific production and process requirements comprehensively.
