Embodiment 1

[0027] Put 96.5kg of carbon material (C content ≥ 95%) into the Raymond mill (or pulverizer), start the machine to crush fineness of 200 mesh through a 200 mesh sieve and 3.5kg of β-Huanhujing (powdered, through a 180 mesh sieve) ) into the stainless steel vacuum double-helix mixing mixer, start the mixer to stir (1 hour), take samples and observe, put it into the stainless steel double-cone vacuum dryer after uniformity, start the machine to adjust the control temperature to 60°C, control time for 3 hours, and then cool down to 20°C -30°C, put the material into a vacuum packing box to obtain 99.5kg of vanadium-nitrogen alloy additive as black crystal powder, and the composition of the two was consistent through sampling and testing.

Embodiment 2

[0029] Put 96.5kg of carbon material (C content ≥ 99%) into the Raymond mill, start the machine to crush fineness of 320 mesh through a 320 mesh sieve and 3.5kg of β-Huanhu essence (in powder form, through a 220 mesh sieve) into the stainless steel vacuum Double-helix mixing mixer for 2 hours and then through a stainless steel double-cone vacuum dryer for 2 hours to control the temperature at 70°C to obtain 99kg of vanadium-nitrogen alloy additive, which is a black crystal powder.

Embodiment 3

[0031] 28.4kg vanadium pentoxide (180 mesh V 2 o 5 Purity ≥ 98.01%), mixed with 8.5kg energy-saving and environment-friendly vanadium-nitrogen alloy additives to make balls, put into a sealed fully automatic double-push plate kiln and gradually heat up to 1450°C in a nitrogen atmosphere, and after 12 hours, V: 77.34, N: 15.61 vanadium Nitrogen alloy 19.55kg.

Abstract

The invention discloses a vanadium-nitrogen alloy additive and a preparation method thereof and belongs to the new material field of special alloy manufacturing and the like. First a carbon material is smashed through a Raymond mill (or a pulverizer), the smashed carbon material and beta-cyclodextrin are placed in a stainless steel vacuum double helix mixer according to the proportion of (27-28):1, are evenly mixed for 1-3 h and then placed in a stainless steel bicone vacuum drying machine, the temperature is controlled to be 55-75 DEG C, and the product is obtained in 3-5 h. The carbon material serves as a raw material, beta-cyclodextrin serves as an excipient, and the carbon material and beta-cyclodextrin are mixed in the stainless steel vacuum double helix mixer and dried in the stainless steel bicone vacuum drying machine to produce the vanadium-nitrogen alloy additive; and the raw material is easy to obtain and the cost is low. The method is stable in process, free of three wastes and suitable for mass production.

Description

technical field [0001] The invention relates to a vanadium-nitrogen alloy additive and a preparation method thereof, belonging to the field of new materials such as special alloy manufacturing. Background technique [0002] Vanadium nitrogen alloy can significantly improve and improve the comprehensive mechanical properties and welding properties of steel such as wear resistance, corrosion resistance, toughness, strength, ductility and thermal fatigue resistance, and can greatly reduce the cost of steelmaking, but its manufacturing The cost is relatively high, the production process route is more complicated, the cycle is long, the energy consumption is high, the equipment scale is large, and the effect of conventional additives is not ideal. [0003] Additives used by Wang Gonghou and others in 1988: activated carbon and iron powder binder with V 2 o 5 For briquette molding, first carry out carbothermal reduction at 1673K and 1.333Pa vacuum to generate VC, and then pass ...
