Full Hydrogen Bell Annealing Furnace from China Suppliers - High Efficiency Factory Heat Treatment Solution
Product Introduction
The configuration ratio between the furnace and the heating cover is reduced. The traditional HNX furnace is 2:1 — two HNX furnaces are equipped with one heating cover. 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 overall investment.
The use of 100% hydrogen as a protective gas, combined with a corrugated inner casing, large gas flow, high-speed burner, combined gas/water cooling, and strong convection, can increase production by 30% to 40%.
No oxidation phenomenon. Through reliable dual PPm-level (parts per million) sealing, sufficient purging time, and advanced control means, annealed steel coils will not exhibit any oxidation discoloration.
