Nitrided silicon-vanadium-iron alloy and production method thereof

Abstract

The invention belongs to the technical field of iron alloy, and specifically relates to nitrided silicon-vanadium-iron alloy and a production method thereof. The provided nitrided silicon-vanadium-iron alloy is composed of the following components in percent by weight: 25-55 wt% of vanadium, 11-26 wt% of nitrogen, 8-20 wt% of silicon, and the balance iron and unavoidable impurities. The provided production method for the nitrided silicon-vanadium-iron alloy comprises: crushing the raw material silicon-vanadium-iron alloy, reacting with nitrogen under high temperature, and cooling to obtain the nitrided silicon-vanadium-iron.

Description

technical field

[0001] The invention belongs to the technical field of iron alloys, and in particular relates to a silicon nitride ferro-vanadium alloy and a production method thereof. Background technique

[0002] The most important technological progress in the iron and steel industry in recent years is the development and application of microalloying technology for iron and steel materials. The commonly used microalloying elements are niobium, vanadium, titanium and so on. They are usually added in the form of carbides or nitrides. From an economic point of view, they are also directly added to silicon-vanadium-iron alloys or silicon-vanadium-iron alloys.

[0003] The industrial-scale application of a large number of vanadium-nitrogen microalloyed steel shows that only when vanadium exists in an effective combined state (vanadium nitride) in the steel can the mechanical properties of the steel be improved to the greatest extent. During the formation process, it has expe...
