Automatic loading system for vanadium-nitrogen alloy and loading method

Abstract

The invention discloses an automatic loading system for a vanadium-nitrogen alloy and a loading method. The system comprises loading equipment and a crucible circulating heating device; the loading equipment comprises a main bin, a sieve, at least one fixing bin and at least one discharging hopper; a feeding port is formed in the top of the main bin; the sieve is obliquely mounted at the bottom of the main bin; a discharging port is formed in the wall of the main bin at the lowest end of the sieve; a vertical gate is mounted on the discharging port and is controlled by a vertical gate air cylinder to be opened and closed; the at least one fixing bin is mounted on the outer side of the discharging port and communicates with the discharging port; a movably-mounted transverse gate is arranged at the bottom of the at least one fixing bin and is controlled by a transverse gate air cylinder to be opened and closed; the at least one discharging hopper is arranged at the lower end of the at least one fixing bin; the crucible circulating heating device comprises a track and at least one row of crucibles placed on the track; the crucibles run on the track in a circulating manner; the loading equipment is fixed at the upper end of the crucible circulating heating device; and the volume of each fixing bin is equal to that of each crucible.

Description

technical field [0001] The invention specifically relates to a vanadium-nitrogen alloy automatic charging system and a charging method. Background technique [0002] As a new type of steel additive, vanadium-nitrogen alloy can replace ferro-vanadium for the production of micro-alloyed steel. It can improve the comprehensive mechanical properties of steel such as strength, toughness, ductility and thermal fatigue resistance, and make The steel has good weldability; at the same strength, the addition of vanadium-nitrogen alloy can save 30-40% of vanadium compared with the addition of vanadium, which reduces the cost. [0003] Vanadium-nitrogen alloys are usually processed and produced by ball-making technology. After being made into a spherical structure, they need to be sent to a high-temperature furnace for high-temperature calcination. Since the production of vanadium-nitrogen alloys by using a pusher kiln has the advantages of high automation, high efficiency and energy sa...

AI Technical Summary

Problems solved by technology

Although it has been attempted to use a mechanical method for charging, the main purpose is to shake off and recycle the powder on the vanadium-nitrogen alloy ball, and it is impossible to realize quantitative charging and synchronization with the operation process of the pusher kiln

[0005] To sum up, there is still a lack of an effective solution to the problem that the vanadium-nitrogen alloy cannot be charged quantitatively during the high-temperature calcination process of the pusher kiln in the prior art, and cannot run synchronously with the pusher kiln.
