Small Carbon Furnace | Design Structure Realizing Low Oxygen x 3000℃ Class
Vacuum replacement, high airtight structure, and graphite heating achieve both low oxygen and treatment at 3000°C level.
The "small carbon furnace" we handle is a heating furnace capable of achieving both a low oxygen atmosphere and ultra-high temperature processing at around 3000°C. In high-temperature processing, residual oxygen and minor leaks within the furnace can lead to oxidation, re-oxidation, and material degradation. This equipment enables ultra-high temperature processing while minimizing the effects of oxygen through vacuum pumping for replacement, a high airtight seal design, and efficient heating with graphite heaters. It is suitable for applications where conventional electric furnaces are insufficient in temperature or atmosphere, such as the graphitization of carbon materials, sintering of ceramics like SiC and B4C, and heat treatment of high melting point materials. 【Features】 ■ Reduction of residual oxygen in the furnace through vacuum replacement ■ Suppression of minor leaks with a high airtight seal design ■ Rapid heating to ultra-high temperature ranges with graphite heaters ■ Stable attainment up to the 3000°C class ■ Structure that easily maintains a low oxygen atmosphere even during long-term operation *For more details, please download the materials or contact us.
basic information
**Reasons for Achieving Low Oxygen and Ultra-High Temperature** ■ Reduction of Oxygen through Vacuum Replacement - Air remaining inside the powder and furnace is expelled through vacuum replacement - Residual oxygen is reduced by replacing it with inert gases such as N2/Ar ■ Leak Suppression through High Air Tightness Structure - Micro leaks are reduced through seal design, machining precision, and assembly accuracy - The atmosphere inside the furnace is maintained stable even during long operation ■ High-Efficiency Heating through Graphite Heating - Achieves ultra-high temperature in a short time through the radiant heat of graphite heaters - Capable of high-temperature processing at around 3000°C ■ Reduction of Oxygen Influence through Carbon Furnace Materials - Furnace configuration that easily suppresses the influence of residual oxygen at high temperatures - Applicable to material processing that is sensitive to oxidation and re-oxidation *Specifications will be proposed according to application, temperature, and atmospheric conditions.*
