Abstract

The invention discloses a high-nitrogen vanadium-titanium alloy, which comprises the following components by weight percentage: 15-40% titanium; 10-30% vanadium; and 5-25% nitrogen. Also disclosed is a production method for producing high-nitrogen vanadium-titanium alloys, including: a) weighing raw materials, the raw materials include ferrovanadium powder and ferrotitanium powder; b) mixing raw materials, mixing the raw materials evenly; c) burning the raw materials system, put the raw materials into the autoclave, then add silicon powder, then close the autoclave and evacuate; and d) add nitrogen-containing gas, pass nitrogen-containing gas into the autoclave, adjust the The pressure in the high-pressure reactor is maintained, and the pressure is maintained until the high-nitrogen vanadium-titanium alloy is released from the furnace. The invention is to mix vanadium and titanium according to a specific ratio and then carry out nitriding. After the titanium is nitrided, oxidation can be effectively avoided, so as to increase the yield of titanium in steel.

Description

technical field [0001] The invention relates to a high nitrogen vanadium titanium alloy and a production method thereof. Background technique [0002] It is well known that vanadium, niobium and titanium are necessary alloying elements for smelting high-grade rebar. A small amount of vanadium, niobium and titanium can greatly improve the crystal structure of steel and significantly improve the tensile and yield strength of steel bars. Vanadium and niobium are very rare and precious metals, while titanium is relatively abundant and cheap. However, titanium is easily oxidized and is not easily absorbed in steel. When used alone, it will cause disadvantages such as molten steel fluidity and cracking. SUMMARY OF THE INVENTION [0003] The invention lies in that vanadium and titanium are mixed according to a specific ratio and then nitrided, and oxidation of titanium can be effectively avoided after nitriding, so as to improve the yield of titanium in steel. And the combinati...
