The rotary kiln (rotating retort furnace) can be used for the thermal treatment of powder materials. It dries and processes the powder materials uniformly by stirring them inside the rotating furnace core tube. In batch type, mixing, drying, and thermal treatment are processed continuously. San Furnace, as a top manufacturer of rotary kilns, handles everything from design and manufacturing to installation and maintenance consistently. 【Problem Solving】We have solved the following issues: ■ Want to use continuous type with 100% hydrogen but concerned about gas leaks. ■ Difficult to achieve continuous processing from powder input to discharge in batch type. ■ Large machines require preheating before operation due to the introduction of large amounts of gas. Please consult us for small lot production, thermal treatment tests, and small sample manufacturing. When processing powder materials, not only heating furnaces but also upstream and downstream equipment, including conveying devices, are necessary. At San Furnace, we provide total proposals that include not only the furnace but also upstream and downstream equipment through collaboration with partner companies. *For more details, please contact us or download the PDF.

When heat treatment is performed in the atmosphere, steel reacts with oxygen, resulting in the formation of oxide scale on the surface, so it is used when one wants to avoid an oxidizing atmosphere. Performing heat treatment in a vacuum atmosphere allows for the degreasing and degassing of organic substances adhered to the surface of the metal material, resulting in a surface with the inherent luster of the metal material after treatment. 【Features】 ● It is possible to enhance the value of metal materials by maintaining their luster. ● Since subsequent processes such as acid cleaning and degreasing are unnecessary, work efficiency is improved. 【Case Studies】 ■ I want to anneal copper without oxidation → 'Vacuum Annealing Furnace' ■ I want to achieve a clean finish on the surface of the treated product → 'Vacuum Quenching Furnace' ■ I want to improve the wettability for brazing → 'Vacuum Brazing Furnace' ■ I want to improve the hot working environment around the furnace → 'Vacuum Furnace'

The "annealing furnace" is a furnace that heats metal materials to soften them, holds them at that temperature, and then cools them slowly to remove residual stress and achieve uniform structure. If the processes of sintering or firing are incomplete, or if the thermal history is significantly affected by factors such as temperature and cooling speed during molding, material reuse, and ambient temperature, the hardness of the structure may become uneven, leading to machining irregularities. By softening the material through annealing treatment, it can exhibit its original material properties. Annealing is also known as "normalizing" or "anneal." 【Features】 ● Appropriate cooling control for rapid cooling, slow cooling, and over-aging is possible. ● Precise temperature distribution can be achieved. ● Various atmosphere gases can be introduced. 【Case Studies】 ■ Want to anneal copper without oxidation → "Vacuum Bright Annealing Furnace" ■ Want to fully anneal steel → "Pit Type Non-Oxidizing Annealing Furnace" ■ Want to anneal castings → "Trolley Type Annealing Furnace" ■ Want to anneal large parts of press products → "Trolley Type Annealing Furnace" / "Pit Type Annealing Furnace" ■ Want to anneal optical glass molded products → "Trolley Type Annealing Furnace"

The size, shape, and material of samples vary depending on the customer. When you have new research and development projects or challenges in new fields that cannot be handled by your existing equipment, you can visit our company to see the results firsthand. 【Testing Examples】 ◆ Tests involving heating treatment with moving samples When powder is heat-treated, unevenness occurs, resulting in inconsistent sample quality. We conducted tests using a rotary kiln that moves the samples, resulting in uniform heat treatment without unevenness. ◆ Tests involving heating treatment with stationary samples During heat treatment tests of powder in a rotary kiln, the powder tends to clump together significantly. Therefore, we introduced a special powder container in a muffle furnace and efficiently processed the powder by directly flowing hydrogen into the powder container, preventing it from solidifying. Many customers are considering transitioning to a rotary kiln when heat treatment does not go well in their current furnace. We also provide suggestions for gases suitable for each sample. We are committed to addressing even the smallest questions and requests from our customers. With the achievements and experience we have cultivated over many years as a manufacturer of industrial furnaces, we provide total support from specification determination to aftercare.

A powder material heat treatment furnace, known as a rotary kiln, is an industrial heat treatment furnace that heats and sinters powder raw materials while stirring them inside a rotating furnace core tube. This equipment can be used for the sintering, sintering, reduction, oxidation, nitriding, and drying of powder materials, including batteries. Since it stirs the powder while drying and heat treating in a rotary manner, there are no inconsistencies. There are two types of rotary kilns: "batch type" and "continuous type." The "batch type" can process mixing, drying, and heat treatment in one go. The "continuous type" can handle larger production volumes. 【Features】 ● It can accommodate 100% hydrogen due to its special gas seal structure. ● It can propose everything necessary for powder processing, including front and rear equipment. ● In the batch type, gas switching is possible during heat treatment. Please consult us for small lot production, heat treatment testing, and small sample manufacturing. If you are considering converting from a batch type to a continuous furnace due to increased processing volume, we can also provide transition proposals.
