FAQ

What Is A Rotary Tube Furnace?

A rotary tube furnace is a circular furnace that rotates during heat-treatment. It is designed to heat loose materials for physiochemical processing and is used for continuous materials processing. These furnaces feature a metal drum lined with refractory, which is mounted at an angle and can burn pulverized, solid, gaseous or liquid fuel into its working section. Rotary tube furnaces have a wide range of applications, including the manufacturing of materials such as alumina, vermiculite, iron ore pellets and cement clinker, as well as for oxidation and calcination processes.

How Does A Rotary Tube Furnace Work?

A rotary tube furnace is a circular furnace that rotates during heat-treatment. It burns fuel and the heating gases created flow towards the sample. The furnace features a metal drum lined with refractory, mounted at an angle. Loose materials are heated for physiochemical processing and the heat is transferred from a heat source to a rotating tube which holds the sample. Rotary tube furnaces are designed for continuous materials processing and have multiple thermal control zones. They have a wide range of applications, including the manufacture of alumina, vermiculite, iron ore pellets, and cement clinker.

What Are The Advantages Of A Rotary Tube Furnace?

The advantages of a rotary tube furnace include improved gas diffusion, reduced gas consumption, increased heat treatment efficiency, and improved product homogeneity. These furnaces provide an efficient way to transfer heat over a short time and continuously run batches of materials. Rotary tube furnaces can be custom designed for specific requirements, including temperature control, workspace size, residence time, tube rotation rate, and atmosphere flow rate. When choosing a tube for a rotary tube furnace, key points to consider include rotational speed, amount of material, tube diameter, suspended length, and tube thickness.

What Is The Function Of Rotary Tube Furnace?

The function of a rotary tube furnace is to heat loose materials for physiochemical processing. The furnace features a rotating tube that holds the sample and applies heat in multiple thermal control zones. Heating gases created by burning fuel flow towards the sample through the furnace. Rotary tube furnaces are used for manufacturing materials such as alumina, vermiculite, iron ore pellets, and cement clinker, as well as for oxidation and calcination processes. These furnaces can be made of ceramic, quartz, or high-temperature alloy and can be built with a wide temperature range for various applications.

What Are The Advantages Of Rotary Tube Furnace?

Rotary tube furnaces offer efficient heat transfer over a short period, continuously processing batches of material while minimizing material handling. The furnace's continuous movement exposes the entire sample surface to the atmosphere, improving gas diffusion and reducing gas consumption to increase heat treatment efficiency.
