Argon purging system:
as international technology makes remarkable progress in to the world of alloys, super alloys and special steels. The requirement for cleaner steel homogeneous chemical composition coupled with the need for reducing production cost as well as increasing productivity has led to development of more efficient metallurgical process become a necessity for mini steel plant.
the process concern itself with production of wide range of steels & high grade alloys steels.
The recognized benefits are:
1 • to make any type of qualitative steel production.
2 • homogenization of melt for chemical analysis.
3 • improvement of purity in terms of gaseous impurities.
4 • to reduce on metallic inclusion.
5 • total quality and killed metal.
6 • purging of argon gas from bottom of the ladle is through pours plug and the main roll of argon purging is to remove non-metallic inclusions from the steel which on purging of argon gas goes to the slag surface.
7 • argon purging shall ensure vigorous slag metal reaction.
8 • homogenization of temperature.
9 control of gases viz h2, n2
10 n2 is an impurity and is undesirable in steel
11 • nitrogen is reactive gas and during nitrogen purging it is picked up in steel and argon is non reactive gas that is best to use for best quality but costly. You can use some nitrogen in start of refining and then argon after that to reduce cost.
12 • argon being neutral gas & non reactive and being used all over the world for purging in steel making operations in secondary steel making.
13 • upper limit for nitrogen ppm varies from grade to grade.
14 • nitrogen is innert gas, there is no chemical reaction with steel.
15 • argon and nitrogen both are considered to be inert gases to be used as purging agents in ladle & furnace. However, you have to be careful while using nitrogen as a purging gas for those steel grades that contains elements like ti, nb, v etc. Which have strong affinity for nitrogen.
