100% Hydrogen Bell-Type Bright Annealing Furnace BMR Type
Bell-type radiant pure furnace BMR type
Higher performance than a vacuum furnace, outstanding productivity in a 100% hydrogen gas atmosphere!
This is a simplified and energy-efficient bell-type bright annealing furnace based on European industrial furnace technology. It uses gas atmospheres such as hydrogen, nitrogen, and argon, and the temperature distribution is within ±5℃ due to hot air circulation! The heating, holding, and cooling times can be reduced by 30%. It allows for uniform annealing, with no variations in hardness, grain size, or tensile strength, resulting in excellent drawability.

basic information
First, the inside of the bell is evacuated to create a vacuum, and the rolling oil attached to the product is degreased while simultaneously purging the air inside the furnace. Then, a protective gas with good thermal conductivity (100% H2 or H2 + N2) is introduced and stirred rapidly with an extremely powerful fan. Additionally, by finely adjusting the heating and cooling rates, the desired grain structure can be easily obtained. Performing annealing in this bell-type furnace eliminates the need for pickling, resulting in no metal loss and no need for wastewater treatment, thus contributing to environmental improvement. ◆ Processing Weight: 3–50 ton/ch ◆ Temperature: 100–800°C ◆ Atmosphere: Vacuum purge N2 + H2 We will make proposals based on the material, application, quantity, weight, building conditions, and other factors of the processed items. *For more details, please download the catalog or contact us.*
