Full Hydrogen Bell Annealing Furnace from China Suppliers - Energy Efficient Factory Solution for Heat Treatment
Product Introduction
The configuration ratio between the furnace and the heating cover is reduced. The traditional HNX furnace is 2:1. Due to the extremely short cooling time of the all-hydrogen furnace, the ratio is reduced to 1.6:1, saving floor area and reducing investment.
Utilizing 100% hydrogen as protective gas, corrugated inner casing, large gas flow, and high-speed burners. Combined gas/water cooling and strong convection can increase production by 30% to 40%.
No oxidation phenomenon occurs due to reliable two PPm level (millionth) sealing. With sufficient washing time and advanced control means, the annealed steel coil will not have oxidation color.
Frequently Asked Questions
What is the advantage of the 1.6:1 furnace ratio?
This reduced ratio compared to the traditional 2:1 HNX furnace allows for significant floor area savings and lower initial investment costs due to the all-hydrogen furnace's extremely short cooling time.
How does the system achieve a 40% production increase?
Efficiency is boosted through the use of 100% hydrogen protective gas, corrugated inner casings, high-speed burners, and a combination of gas/water cooling with strong convection.
What prevents oxidation during the annealing process?
Oxidation is eliminated by achieving a reliable two PPm level (one-millionth) seal, combined with advanced control systems and optimized washing times.
What type of protective gas is used in this furnace?
The system utilizes 100% hydrogen as a protective gas to ensure high-quality results and faster production cycles.
Will the annealed steel coils show any discoloration?
No, thanks to the PPm level seal and precise control of the environment, the annealed steel coils will not exhibit any oxidation color.
How is the cooling process managed?
The system employs a combined gas and water cooling method along with strong convection to achieve rapid cooling times.
