Description

Technical Field

[0001] This utility model relates to the field of vanadium-nitrogen alloy technology, and in particular to a high-efficiency stirring and mixing device for vanadium-nitrogen micro-alloying. Background Technology

[0002] Vanadium-nitrogen alloy is a new type of alloying additive that can replace ferrovanadium in the production of microalloyed steel. The addition of vanadium nitride to steel can improve the comprehensive mechanical properties of steel, such as strength, toughness, ductility, and resistance to thermal fatigue, and also give the steel good weldability. Under the same strength, the addition of vanadium nitride can save 30-40% of the vanadium addition, thereby reducing costs. Vanadium-nitrogen alloy can be used in structural steel, tool steel, pipe steel, reinforcing steel, and cast iron. When applied to high-strength low-alloy steel, vanadium-nitrogen alloy can simultaneously and effectively perform vanadium and nitrogen microalloying, promote the precipitation of carbon, vanadium, and nitrogen compounds in the steel, and more effectively exert the effects of precipitation strengthening and grain refinement.

[0003] While existing mixing equipment can complete the mixing process, the mixing effect and speed are not ideal. To address this issue, application number 201922007770.X discloses a mixer for vanadium-nitrogen alloy production. This mixer includes a frame, a mixing tank mounted on the frame, a fixed base at the bottom of the mixing tank, and the mixing tank and fixed base being fixedly connected to the frame by bolts and nuts. Multiple feeding conveyor belts are mounted on the outside of the mixing tank. Multiple feeding hoppers corresponding to the feeding conveyor belts are mounted above the mixing tank. This vanadium-nitrogen alloy production mixer, through its structure of frame, feeding conveyor belts, feeding hoppers, mixing tank, base, mixing device, upper mixing impeller, lower mixing impeller, upper rotating rod, lower rotating rod, gear, feeding channel, power mechanism, electric motor, and gearbox, achieves the function of simultaneous automatic feeding and rapid, efficient mixing of multiple raw materials. During the feeding process, the differential rotation of the multiple layers of mixing impellers enables small-batch, high-efficiency, and rapid mixing, thereby greatly improving production efficiency and reducing energy consumption.

[0004] The above-mentioned patent has the following problems when used: During the mixing and stirring of raw materials, due to the addition of binder, a large amount of mixture adheres to the inner wall of the stirring vessel when mixing iron powder, vanadium pentoxide and carbon powder, resulting in uneven mixing. There is room for improvement.

[0005] Therefore, we propose a high-efficiency stirring and mixing device for vanadium-nitrogen microalloying to solve the problems in the background technology.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

At the same time, the gear ring 4 meshes with the three gears 15, causing the three gears 15 to drive the three stirring rods 12 to rotate on the cover plate 10, and the three stirring rods 12 to drive the corresponding stirring blades to rotate synchronously, thereby achieving the effect of mixing and stirring the vanadium-nitrogen alloy raw materials.

[0039] The centrifugal force generated by the rotation of the vanadium-nitrogen alloy mixing tank 1 causes the vanadium-nitrogen alloy raw material to move towards the edge of the vanadium-nitrogen alloy mixing tank 1, thereby facilitating the mixing of the vanadium-nitrogen alloy raw material by the three stirring rods 12 and improving the mixing effect.
