Problems solved by technology

That is, the entire vanadium nitride is completed separately in two sets of equipment, because of its low efficiency, large equipment investment and high manufacturing cost
[0006] 2. The methods for preparing vanadium nitride adopted by the above two companies are not continuous production methods from the strict concept of metallurgical process
As a result, there is no continuous production of vanadium nitride production process

Embodiment

[0047] According to the production process of the present invention, 4 batches of vanadium nitride alloys were trial-produced on the device for continuous production of vanadium nitride alloys described in the present invention. The composition and ratio of the 4 batches of raw materials equipped are shown in Table 1. After the raw materials are prepared, the pellets enter the hopper through mixing, pressing, molding and drying. The size and drying parameters of the pellets are listed in Table 2. The pellets enter the reduction and nitriding vertical electric furnace from the hopper through the feed port, and then enter the reduction and nitriding section through the preheating section and the pre-reduction section. The temperature ranges of the pre-reduction section, the reduction nitriding section, and the nitrogen flow rate entering the reduction nitriding vertical electric furnace are listed in Table 3. Finally, vanadium nitride is produced through reduction nitriding in ...

Abstract

A technology for continuously producing vanadium nitride alloy includes such steps as proportioning raw materials (V2O5, carbon reducer and liquid adhesive), mixing, die pressing, baking, reductive nitrifying, and refining. Its advantages are high productivity, high quality and low cost.

Description

technical field [0001] The invention belongs to the field of iron and steel metallurgy, and relates to a production method and a device for a vanadium nitride alloy. Background technique [0002] Vanadium is one of the most commonly used and most effective strengthening elements in the production of microalloyed steels, and nitrogen is a cost-effective alloying element in vanadium-containing steels. [0003] The vanadium and nitrogen microalloying technology makes full use of the cheap nitrogen element, optimizes the precipitation of vanadium, better plays the role of fine grain strengthening and precipitation strengthening, and significantly improves the strength of steel. What is more practical is the use of vanadium and nitrogen microalloying to obtain higher strength at low vanadium content, which obviously saves vanadium content and reduces the production cost of steel. Vanadium nitrogen microalloying technology has been maturely applied in the development of high-stre...
