サーモニックENG Product Lineup

There are many types of electric furnaces, including tubular furnaces, box-type furnaces, vacuum furnaces, atmosphere furnaces, metal furnaces, carbon furnaces, and chlorine furnaces. Selecting the appropriate furnace that matches the application and conditions requires specialized organization. At our company, we can work together from the initial stages to determine which furnace type may be suitable by confirming the temperature, atmosphere gas, processing volume, sample shape, and purpose. We can consult even if the specifications are not yet finalized. You can discuss questions such as "Can it be processed at this temperature?" "Can this gas be used?" "Can it be handled with existing furnaces?" and "Can we conduct a test first?" It is also possible to conduct tests and condition setting with small samples before introducing the equipment to confirm the feasibility of the process. For treatments involving special atmospheres, high temperatures, vacuum, corrosive gases, and reactive gases, which are difficult to handle with standard furnaces, we can consider custom specifications. 【Features】 ■ You can consult from the stage where you are unsure about the type of electric furnace that suits your application, even after researching online. ■ We can respond from the initial organization stage, even if the temperature, atmosphere, processing volume, and sample shape are not yet determined. *For more details, please download the PDF or feel free to contact us.

Are you considering sintering, chlorination reactions, and corrosion evaluation in a special atmosphere such as Cl₂ and HCl? In sintering using corrosive and reactive gases like Cl₂ and HCl, it is necessary to consider specifications not only for temperature and gas concentration but also for materials inside the furnace, jig materials, sealing materials, piping, valves, exhaust piping, pollution control devices, and safety interlocks. In particular, for chlorination reactions and volatile separation, the volatility of the generated chlorides, condensation location, recovery methods, insulation of exhaust piping, and pollution control capabilities are important. Additionally, since corrosive gases are handled, leak prevention measures, gas detection, exhaust routes, and safety shutdown conditions significantly impact equipment specifications.

Are you considering thermal treatment and firing evaluation in an H₂ reduction atmosphere? In processing under an H₂ reduction atmosphere, it is important to first clarify "what you want to reduce." Depending on the objective—such as the reduction of oxides, removal of surface oxide films, reduction of metallic impurities and residues, or treatment of powders, substrates, jigs, and components—the required temperature, H₂ concentration, holding time, and evaluation criteria will vary. Additionally, when processing with 100% H₂, high reduction power can be expected; however, it is crucial to consider specifications for replacement procedures, leak management, exhaust dilution, decontamination, and safety interlocks. When processing with diluted H₂ below the explosion limit, it is easier to lean towards safety, but there may be a risk of insufficient reducing power, necessitating verification of temperature, time, flow rate, and dilution ratio. This document organizes the reduction objectives, H₂ concentration, dilution gas, furnace configuration, safety measures, and points for reflecting on equipment specifications in H₂ reduction atmosphere thermal treatment. - For thermal treatment and firing evaluation in an H₂ reduction atmosphere - For comparative examination of 100% H₂ and diluted H₂ conditions - For oxide reduction, deoxygenation, and removal of surface oxide films - For organizing specifications of H₂ gas replacement, exhaust dilution, and safety interlocks - For firing tests and furnace type selection before equipment installation

Are you considering sintering and heat treatment with N₂・Ar atmosphere to suppress oxidation? Simply flowing inert gas is not sufficient to suppress oxidation. It is necessary to determine conditions that include the introduction of oxygen and moisture into the furnace, replacement procedures, gas flow rates, dew point, residual O₂, sample shape, jig material, and re-oxidation during cooling. Additionally, while N₂ is relatively low-cost and easy to use for general oxidation suppression, there is a possibility of nitriding or reactions depending on the material. Ar/He has low reactivity and is suitable for high-purity processing and high-temperature treatments, but it is important to consider gas costs, replacement amounts, and leak management.

Our company offers a "Multi-Atmosphere Furnace" designed to handle the firing process that generates harmful gases such as NH3, CO, and NOx. During the firing of raw materials containing organic substances, resin-based materials, catalyst carriers, and battery materials, gases such as NH3, CO, NOx, HCN, and hydrocarbon gases may be emitted during heating and holding. Gases that were not an issue in small tubular furnaces or small-scale tests can become significant challenges in terms of exhaust concentration, emission volume, corrosiveness, and safety measures as the number of tray layers and processing volume increase. Our Multi-Atmosphere Furnace can design the entire firing process, including vacuum replacement, atmosphere control, heating, exhaust, and coordination with emission treatment equipment. 【Features】 ■ Furnace design considering the generation of gases such as NH3, CO, and NOx ■ Gas replacement in the furnace before and after processing through vacuum replacement ■ Compatibility with various atmospheres such as N2, Ar, Air, and NH3 ■ Consideration of emission treatment methods such as scrubbers, catalytic oxidation, and thermal oxidation ■ Support for scale-up considerations anticipating increased tray layers and processing volume *For more details, please download the materials or contact us.

The "carbon furnace" we handle is an electric furnace designed for high-temperature processing at around 3000°C in an extremely low-oxygen atmosphere. By using vacuum replacement, the air inside the furnace is preemptively expelled, and the getter effect of the carbon material reduces residual oxygen and oxidizing components. It is structured to suppress oxidation, decarburization, and re-oxidation in high-temperature regions, making it easier to reproduce processing conditions such as graphitization, carbonization, nitridation, and high-temperature modification. It can be applied to high-temperature processing of carbon materials, carbon black, CNT, CNF, graphite sheets, ceramics, powder metallurgy materials, semiconductor fixtures, and more. 【Features】 ■ High-temperature sintering in an extremely low-oxygen atmosphere ■ Usable at a constant 2800°C, with a maximum of 3000°C ■ Reduction of residual air in the furnace through vacuum replacement ■ Oxygen getter effect from the carbon material ■ Design allows for simultaneous processing of multiple samples with a saya-tray configuration *For more details, please download the materials or contact us.
