Batch-type rotary kiln

Batch-type rotary kiln

It is possible to switch the atmosphere gas during heat treatment.

In a batch-type rotary kiln, it is possible to switch the atmosphere gas during the heat treatment process. This is effective when you want to reduce the use of expensive atmosphere gases at the start of heating at room temperature. Additionally, it allows for the mixing, drying, and heat treatment processes to be handled all at once. 【Selection Points for Batch-Type Rotary Kilns】 ■ Want to process mixing, drying, and heat treatment in one step ■ Requires a long processing time ■ Has many temperature stages Please consult us for small lot production, heat treatment testing, and small sample manufacturing. As processing volume increases, it is also possible to modify from a batch type to a continuous furnace. When handling powder processing, not only the heating furnace but also the upstream and downstream equipment, including the conveying system, is necessary. At San Furnace, we provide comprehensive proposals that include not only the furnace but also the upstream and downstream equipment through collaboration with partner companies. *For more details, please contact us or download the PDF.

[Case Study] Proposal for Heat Treatment Method for Prototypes

[Case Study] Proposal for Heat Treatment Method for Prototypes

Solutions for precision and distortion issues! Introduction of heat treatment examples for prototypes.

This is a case study regarding a request for heat treatment "salt quenching" for SK material prototypes. 【Consultation Details】 We want to achieve a hardness of HRC 50 or higher, but performing salt quenching with the material as is leads to issues with precision and distortion. 【Solution Case】 We proposed changing the material from SK to SPCC and altering the heat treatment method to gas soft nitriding. This not only achieved a hardness of HRC 50 or higher, but also reduced the total cost of mass-produced items and improved the lifespan of the molds. At Meinetsu, we offer heat treatment solutions tailored to our customers' needs.

Vacuum heat treatment furnace

Vacuum heat treatment furnace

Seamless temperature measurement is possible in multi-room types (patented).

In heat treatment that spans multiple processing rooms, by devising the structure of adjacent rooms, it is possible to prevent atmospheric confusion and enable prompt and accurate temperature measurement. Additionally, conventional thermocouples for heat treatment equipment can be used and are easily detachable. With a "vacuum furnace," you can maintain brightness and enhance the value of metal materials. Since subsequent processes such as acid cleaning and degreasing are unnecessary, work efficiency improves, and energy-saving effects can be expected. 【Features】 ■ It is possible to enhance the value of metal materials by maintaining brightness. ■ Work efficiency improves as subsequent processes such as acid cleaning and degreasing are no longer necessary. 【Problem-Solving Examples】 We have addressed the following challenges: ■ Required hardness cannot be achieved due to heat loss during oil quenching. ■ We want to automate the process of pre-cleaning → carburizing → oil quenching → oil cleaning → tempering. ■ We want to digitize the results of heat treatment and the history of the processes. 【Implementation Examples】 ■ We want to anneal copper without oxidation → "Vacuum Annealing Furnace." ■ We want to achieve a clean finish on the surface of processed items → "Vacuum Quenching Furnace." ■ We want to improve the wettability of brazing → "Vacuum Brazing Furnace." ■ We want to improve the hot working environment around the furnace → "Vacuum Furnace." *For more details, please contact us or download the PDF.

Batch-type rotary kiln capable of switching atmosphere gases during heat treatment.

Batch-type rotary kiln capable of switching atmosphere gases during heat treatment.

Depending on the characteristics of the material being processed, it is possible to switch the atmosphere gas to the target temperature during heat treatment.

In a batch-type rotary kiln, it is possible to switch the atmosphere gas during the heat treatment process. This is effective when you want to minimize the use of expensive atmosphere gases at the start of heating at room temperature. Additionally, it is possible to combine mixing, drying, and heat treatment processes into one operation. 【Specifications】 ● Temperature: 200–960℃ ● Effective dimensions: φ1150×L1850 ● Atmosphere: Hydrogen / Nitrogen ● Applications: Hydrogen reduction / Annealing ● Processed material: Metal powder ● Processing capacity: 1300kg/ch ● Electrical capacity: 156kW 【Selection Points for Batch-Type Rotary Kiln】 ■ Want to process mixing, drying, and heat treatment in one step ■ Processing time is long ■ There are many temperature steps Please consult us for small lot production, heat treatment testing, and small sample manufacturing. It is also possible to modify from a batch type to a continuous furnace as processing capacity increases. When performing powder processing, not only the heating furnace but also the upstream and downstream equipment, including the conveying system, is necessary. At San Furnace, we provide total proposals that include not only the furnace but also the upstream and downstream equipment through collaboration with partner companies. *For more details, please contact us or download the PDF.

[Technical Column] Explanation of Types and Components of Heating Furnaces and Heating Methods

[Technical Column] Explanation of Types and Components of Heating Furnaces and Heating Methods

We will provide a detailed explanation of the structure, features, and types of heating furnaces, which are important production equipment for realizing heat treatment technology!

The heating furnace is used in various industries and is a device for performing "heat treatment" to bring out the properties of metals such as iron and steel. By applying heat treatment, metals can change their hardness and toughness, allowing them to possess properties suitable for their intended applications. Typical heat treatments include "quenching," "tempering," "annealing," and "normalizing." Not limited to the automotive industry, it has become essential for the development of Japan's core industries such as the machinery industry, supporting the quality of Japanese manufacturing. This article will provide a detailed explanation of the structure, characteristics, and types of heating furnaces, which are important production equipment for realizing such heat treatment technology. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.

Minimize deformation! Heat treatment "Gas Nitriding Treatment"

Minimize deformation! Heat treatment "Gas Nitriding Treatment"

For heat treatment, go to Meinetz! The heat treatment "gas soft nitriding" improves corrosion resistance and wear resistance.

Even for shafts and similar components that are prone to distortion, warping, and deformation, precise heat treatment is possible through Meinetsu's years of expertise and the latest processing method, "gas soft nitriding." "Gas soft nitriding" is a heat treatment that maintains a temperature range of 550 to 600°C in a mixed atmosphere of carburizing gas and NH3 (ammonia), allowing nitrogen and carbon to diffuse into the surface to form carbonitrides, thereby achieving surface hardening. Additionally, because it operates within a temperature range that does not cause changes in the metal structure, it results in a treatment that is less prone to deformation and dimensional changes. This method is actively adopted for sliding parts, wear-resistant components, and resin molds. 【Features】 ■ Strong improvement in wear resistance and corrosion resistance ■ Effective in suppressing distortion, suitable for products with strict dimensional accuracy ■ Adopts retort peripheral cooling method to reduce load on products ■ Minimal nitriding unevenness, resulting in a beautiful (silver-gray) finish ■ Capable of handling sizes up to Φ600mm×1000mm

Gas Nitriding Treatment to Solve Your Problems During Quenching

Gas Nitriding Treatment to Solve Your Problems During Quenching

For sliding parts, wear-resistant parts, and resin molds! Solve distortion, finishing, and cost issues during hardening with "gas nitriding treatment"!

Gas soft nitriding treatment is a heat treatment that forms carbonitrides on the surface by diffusing nitrogen and carbon through heating and holding in a mixed atmosphere. It features not only wear resistance but also less distortion compared to quenching, with surface hardness equivalent to that achieved during quenching, and a faster finishing time. By hardening relatively inexpensive materials, it is also possible to achieve the same hardness as more expensive materials. Additionally, while the basic finishing characteristics such as hardness do not change between "salt bath soft nitriding" and "gas soft nitriding," gas soft nitriding results in a cleaner appearance after treatment, leading to fewer processing steps and quicker completion. Products that are currently treated with salt bath nitriding should also be considered for gas soft nitriding. 【Features】 ■ High wear resistance and corrosion resistance ■ Effective for products with strict dimensional accuracy, minimizing distortion ■ Adopts a retort outer cooling method to reduce stress on the product ■ Minimal nitriding unevenness, resulting in a beautiful (silver-gray) finish ■ Suitable for sliding components, wear-resistant parts, and resin molds We can accommodate requests for one-off or small-lot heat treatments for prototypes and development.
