what is split tube furnace?
Split tube furnaces are a popular choice for laboratories as they are extremely versatile. They consist of a furnace body which is split in half, attached by a hinge. This allows easy access to place and remove samples and a range of tube diameters can be used with split tube furnaces.
Natural Gas Furnace with Atmospheric Controls
At Thermcraft, we have manufactured a robust natural gas furnace that meets military specifications, with a high temperature capacity of up to 1371°C (2500°F) and a temperature uniformity of within +/-25°F. This immense machinery is constructed from a continuously welded shell of plate steel and structural joists with high-performance ceramic fiber blanket insulation installed in the walls and roof of the furnace.
Why Use a Tube Furnace?
Numerous thermal processing formats are available to researchers and manufacturers handling relatively small-volume samples or operations with low throughput. At these scales, benchtop laboratory ovens tend to excel – yet the geometry of the thermal processing chamber can be a limiting factor in certain application areas.
What is a horizontal tube furnace?
A horizontal tube furnace is an electric thermal processing solution with a characteristic heating chamber comprised of a continuous piece of high-temperature insulation, or two semi-cylindrical elements. They are often consequently defined as either solid or split tube furnaces.
Benefits of Horizontal Tube Furnaces
Now that we have recapped the basics, let us look at the main benefits of horizontal tube furnaces and how they enable leading-edge performance in specific application areas.
Unmatched Thermal Uniformity
The primary benefit of tube furnaces is their unmatched thermal uniformity. Workpieces in the hot zone are subjected to sustained temperatures of up to 1800°C (3272°F) across their full 360° axis

An inert atmosphere, sometimes referred to as a protective atmosphere, produces very clean parts in a highly controlled environment. It also serves to prevent unwanted chemical reactions (like oxidation or decarburization) from occurring on the surface of the part.
Heat Treatment Processes That Require Controlled Atmospheres
There are several different heat treatment processes that may require a controlled atmosphere in order to be successful. Those requiring either an inert atmosphere or a hydrogen atmosphere include the following:
Why Furnace Atmosphere Is Important？The atmosphere in a heat treatment process can be a critical factor: it may act as a carrier for key elements in the process, or it may act to protect the part being heat treated from the effects of exposure to air while also exposed to substantially elevated temperatures. As a carrier, the atmosphere is chemically reactive with the surface and leads to improved surface characteristics to support processes such as
The working principle of a lab muffle furnace which is also known as a retort furnace is toheat the air inside its chamber using the basic fundamentals of thermal convection andthermal radiation. The name muffle furnace is derived from the fact that the internalceramic chamber of the furnace which is also known as muffle is wrapped up in vastlayers of insulation so as to prevent heat loss and achieve high temperatures.
