Description

technical field [0001] The invention relates to the technical field of vanadium-nitrogen alloys, in particular to a reverse cycle double-push vanadium-nitrogen alloy production device and process. Background technique [0002] Vanadium-nitrogen alloy and vanadium nitride, vanadium-nitrogen alloy is a new type of alloy additive, which can replace ferro-vanadium for the production of alloyed steel. The addition of vanadium nitride can improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, and make the steel have good weldability. Under the same strength, adding vanadium-nitrogen alloy can save 30%~40% of the amount of vanadium-nitrogen added, thereby reducing the cost; at present, there are 32 domestic vanadium-nitrogen alloy production enterprises. [0003] At present, the production of vanadium-nitrogen alloys often uses auxiliary pits for preheating, and single-channel chambers for carbonization and n...

AI Technical Summary

Problems solved by technology

[0003] At present, the production of vanadium-nitrogen alloys often uses auxiliary pits for preheating, and single-channel chambers for carbonization and nitriding sintering. Due to the limitations of technology and equipment, the construction cost and energy consumption are relatively high, but the production efficiency is not high.
