Abstract

The invention relates to silicon vanadium nitride which comprises the following components in percentage by weight: 52-55 wt percent of vanadium, 13-15 wt percent of nitrogen, 6-10 wt percent of silicon and the balance of iron and inevitable impurities, wherein the mass ratio of vanadium to nitrogen is 3.6-4.5. A silicon vanadium nitride alloy can be prepared through high-temperature self-propagating reaction. According to the silicon vanadium nitride alloy disclosed by the invention, by adding the element silicon in the alloy, controlling the element silicon content in the alloy and controlling the contents of vanadium and nitrogen as major elements and the ratio of vanadium and nitrogen, the absorptivity and the stability of the silicon vanadium nitride alloy are greatly improved; and in addition, the silicon vanadium nitride alloy is a vanadium microalloy in most vanadium saving at present and has excellent market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of ferroalloy preparation, and more specifically, the invention relates to a silicon vanadium nitride and a production method thereof. Background technique [0002] The alloying of steel is usually based on manganese and silicon; microalloys refer to ferroalloys that add trace carbon and nitrogen forming elements such as niobium, vanadium, and titanium on the basis of the main ferroalloy, and are widely used in the production of high-strength steel bars and low-strength steel bars. Alloy high-strength steel, pipeline steel, H-beam, medium and heavy plate, etc. [0003] Microalloys generally have the following characteristics: (1) The added carbonitride-forming elements strengthen the mechanical properties of steel through the "dissolution-precipitation" behavior during the heating and cooling process of steel; The mechanism is mainly fine grain strengthening and precipitation strengthening; (3) Microalloyin...
