Has anyone worked with molten steel slag before?

Has anyone worked with molten steel slag before?

Has anyone worked with molten steel slag before?

(OP)
I have been given the project of designing a runner system for molten steel slag. The assumed temperature is around 3000-4000 F. Right now, I am just assuming that the flow would be similar to concrete. Any help on this matter would be greatly appreciated.

RE: Has anyone worked with molten steel slag before?

I worked in an iron foundry and observed the flow of the slag frequently. It flows better than concrete--more like a high viscosity newtonian fluid.

RE: Has anyone worked with molten steel slag before?

It is stickey and stringy, but the properties depend on the composition.  Some of it is almost like foam, aome is more like mud.
Are you to design a replacement system? Is there any way for you observe something in use?

Yes,stringy and sticky like molasses or honey.

RE: Has anyone worked with molten steel slag before?

My first idea was to make runner system that runs about 15 feet and elevation of about 7 feet. This leads to the pit on the lower level. However, I am not sure if the slag will make it that far. Whether it solidifies itself or having to high of viscousity and goes no where. I know if we are producing high carbon steel it does not flow as well, kind of like candle wax. On low carbon, I was told it flows similar honey. Also, we add a material called "Accutherm" to help the heat from being dissipated from the steel. This doesn't help the flow either. Yes, I am designing a replacement system. Thank you guys for you advice and comment.

RE: Has anyone worked with molten steel slag before?

For most steelmaking slags, if its chemical composition is known, it is possible to find its viscosity for a given temperature range in many references.  Compare the viscosity value of your slag with that of other fluid you are familiar with will tell you how it will flow.

WayneLee,

Did you go to U of I in the Early 90's?

(sorry for the off-topic, I just owe a guy named 'Wayne Lee' an apology...)

No, this is not my real name, my real name is Hoang Le. Wayne Lee is easier to pronouce and if I was given a american name, then this would be it.

RE: Has anyone worked with molten steel slag before?

I recall that are additives that are put in after the slag is dumped to change it's texture.  I believe that it is mostly to make it easier to crush, but it may also have to do with reducing sticking.
I can't find the information, but then it isn't my area.
