Nitrided Ferro Silicon Introduction and application

 

Ferro silicon nitride is a Si3N4 as the main ingredientalong with free iron, no-nitride Ferro Silicon and small amounts of other components of the mixture. Ferro Silicon Nitride of refractory is a kind of gray powder,and it is the gray granular matter when used for steel making.

 

The powder ferrosilicon is mainly used for the closure of a large blast furnace taphole clay, and a small amount of it is used in the iron ditch material or other unshaped refractory materials.

 

The granular nitrided ferro silicon is mainly used for oriented silicon steel or other steels that use nitride to increase strength (such as HRB400 rebar).

 

Nitrided Ferro Silicon in the blast furnace taphole clay are universally applied in the developed countries to significantly improve the opening blocked and meet the needs of the blast furnace.It is an indispensable ingredient of modern large-scale blast furnace taphole clay. adding a small amount of ferro silicon nitride in ferrous material greatly improve the iron content of iron trough. Japan began to use it in the 1970s.

In steelmaking, granular Nitrided Ferro Silicon is originally used in grain oriented silicon steel, stainless steel, heat-resistant steel, corrosion-resistant steel, alloy steel and special steel smelting production.It is relatively stable to add a certain amount of nitrogen for the molten steel. Nitrided Ferro Silicon is a cheap nitrogen alloy. production HRB400 reinforced FeV50 + Fe Si3N4 micro-alloying program, the cost of alloying than a single FeV50 ton of steel cost is reduced by 127.61 yuan, lower than the ton of steel cost VN12 microalloying 44.21yuan. If the technology has been popularized, that will be the benifit for construction steel production and reducing cost and increasing profit.

 

The domestic application of nitrided ferro silicon is in a relatively short time, Baosteel first added ferro silicon nitride to blast furnace taphole clay, the taphole clay properties are improved to meet the needs of Baosteel, many other steel mills in China are basically using nitrided ferro silicon , Adding nitrided ferro silicon stemming is very good to meet the needs of large-scale blast furnace, the blast furnace tapping times from 18 decreased to 12, the lowest down to 6, the consumption of taphole clay reduced by 1.2kg/ tons of iron to 0.5kg/ tons of iron.In the past 3 years, the blast furnace tap hole clay that above 2000M3 of the national key large-scale iron and steel enterprise are basically using it.
